A film distribution manager calculates that 9% of the films released are flops. If the manager is correct, what is the probability that the proportion of flops in a sample of 701 released films would be greater than 7%? Round your answer to four decimal places. Please show how to enter short hand in calculator.
Answer:
The probability that the proportion of flops in a sample of 701 released films would differ from the population proportion by greater than 7% is 0.00001
Step-by-step explanation:
We are given;
Probability that the films released are flops = 9% = 0.09
Sample size = 701
Formula for standard deviation is;
σ = √(p(1 - p)/n)
σ = √(0.09(1 - 0.09)/701)
σ = √0.0001168331
σ = 0.0108
We want to find the probability that the proportion of flops in a sample of 701 released films would be greater than 7%.
Thus, it means x - μ = 7% = 0.07
Z-score formula here is;
z = (x - μ)/σ
z = 0.07/0.0108
z = 6.4815
From online p-value from z-score calculator attached using; z = 6.4815, Nominal significance level = 0.05, two tailed distribution, we have;
P-value = 0.00001

Eugene's grandmother is teaching him how to make her salsa recipe. Each batch of salsa requires 1 4 of a cup of red onions. If they have 1 1 2 cups of red onions, how many batches of salsa can they make? batches of salsa (Enter all mixed numbers as x y/z.)
Answer:
They can make six salsa batches
Step-by-step explanation:
Here, we are told that each salsa batch require 1/4 of a cup of red onions and they have 1 1/2 cups, we want to know the number of batches of salsa that can be made
Mathematically, that would be 1 1/2 divided by 1/4
That is;
3/2 divided by 1/4
Hence;
3/2 * 4/1 = 12/2 = 6
They can make six batches of salsa
If the cosmic radiation to which a person is exposed while flying by jet across US is a random variable having mean 4.35 mrem and standard deviation 0.59 mrem,find the probabilities that the amount of cosmic radiation to which a person will be exposed on such a flight is:_______
(a) Between 4.00 and 5.00 mrem
(b) At least 5.50 mrem
(c) Less than 4.00 mrem
Answer:
a
[tex]P(4.00 < X < 5.00) = 0.58818 [/tex]
b
[tex]P(X \ge 5.5) = 0.02564 [/tex]
c
[tex]P(X < 4 ) = 0.27652[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 4.35[/tex]
The standard deviation is [tex]\sigma = 0.59[/tex]
Generally the probability that the amount of cosmic radiation to which a person will be exposed on such a flight is between 4.00 and 5.00 mrem is mathematically represented as
[tex]P(4.00 < X < 5.00) = P(\frac{ 4 - \mu }{\sigma} < \frac{X - \mu}{\sigma} < \frac{ 5 - \mu }{ \sigma} )[/tex]
Here [tex]\frac{X - \mu}{\sigma} = Z (The \ standardized \ value \ of \ X )[/tex]
=> [tex]P(4.00 < X < 5.00) = P(\frac{ 4 - 4.35 }{0.59} < Z < \frac{ 5 - 4.35 }{ 0.59} )[/tex]
=> [tex]P(4.00 < X < 5.00) = P(-0.59322 < Z < 1.1017 )[/tex]
=> [tex]P(4.00 < X < 5.00) = P( Z < 1.1017 ) - P(Z < -0.59322) [/tex]
From the z -table the probability of ( Z < 1.1017 ) and (Z < -0.59322) are
[tex]P( Z < 1.1017 ) =0.8647[/tex]
and
[tex]P( Z < -0.59322 ) =0.27652[/tex]
So
=> [tex]P(4.00 < X < 5.00) = 0.8647 - 0.27652 [/tex]
=> [tex]P(4.00 < X < 5.00) = 0.58818 [/tex]
Generally the probability that the amount of cosmic radiation to which a person will be exposed on such a flight is At least 5.50 mrem is mathematically represented as
[tex]P(X \ge 5.5) = 1- P(X < 5.5)[/tex]
Here
[tex]P(X < 5.5) = P(\frac{X - \mu }{\sigma} < \frac{5.5 - 4.35}{0.59} )[/tex]
[tex]P(X < 5.5) = P(Z< 1.94915) [/tex]
From the z -table the probability of (Z< 1.94915) is
[tex]P(Z< 1.94915) = 0.97436[/tex]
So
[tex]P(X \ge 5.5) = 1- 0.97436[/tex]
=> [tex]P(X \ge 5.5) = 0.02564 [/tex]
Generally the probability that the amount of cosmic radiation to which a person will be exposed on such a flight is less than 4.00 mrem is mathematically represented as
[tex]P(X < 4) = P(\frac{X - \mu }{\sigma} < \frac{4 - 4.35}{0.59} )[/tex]
[tex]P(X < 4) = P(Z< -0.59322) [/tex]
From the z -table the probability of (Z< 1.94915) is
[tex]P(Z< -0.59322) = 0.27652[/tex]
So
[tex]P(X < 4 ) = 0.27652[/tex]

An oilfield contains 6 wells that produce a total of 1,800 barrels of oil per day. For each additional well that is drilled, the average production per well decreases by 25 barrels per day.
Required:
How many additional wells should be drilled to obtain the maximum amount of oil per day?
Answer:
The additional wells for maximum amount of oil per day is 3 wells.
Step-by-step explanation:
Given;
initial number of wells, n = 6
total production, T = 1800
average production per well, = 1800/6 = 300 barrels per day
Let the additional well = y
total number of wells after optimization = 6 + y
new production per well = 300 - 25y
new total production = (6+y)(300-25y)
t = 1800 - 150y + 300y - 25y²
t = 1800 + 150y - 25y²
dt / dy = 150 -50y
for maximum value, dt/dy = 0
150 - 50y = 0
50y = 150
y = 150 / 50
y = 3
Therefore, the additional wells for maximum amount of oil per day is 3 wells.
33 additional wells should be drilled, reaching 39 wells, to obtain the maximum amount of oil per day.
Given that an oilfield contains 6 wells that produce a total of 1,800 barrels of oil per day, and for each additional well that is drilled, the average production per well decreases by 25 barrels per day, to determine how many additional wells should be drilled to to obtain the maximum amount of oil per day, the following calculation must be performed:
1800 x 6 = 10800 1200 x 30 = 36000 1000 x 38 = 38000 950 x 40 = 38000 900 x 42 = 37800 975 x 39 = 38025
Therefore, 33 additional wells should be drilled, reaching 39 wells, to obtain the maximum amount of oil per day.

Am eastern cotttentail rabbit and ferret weigh 7 lbs together. The ferret weighs 2 lbs more than the rabbit. Create a system of equations to represent the scanario. How much does each weigh. If the answer is not an integer write as a decimal.
Answer:
Step-by-step explanation:
The first equation is the weights of the rabbit and the ferret together which is
r + f = 7.
The second equation puts the weight of the ferret in terms of the rabbit. If the ferret's weight is 2 pounds more than the rabbit, then
f = r + 2 (the word "is" means equals). Since we know what f is equal to, we will sub it into the first equation and solve for r:
r + (r + 2) = 7 and
2r + 2 = 7 and
2r = 5 so
r = 2.5 pounds.
A rabbit weights 2.5 pounds and the ferret weights 7 - 2.5 which is 4.5 pounds.

Answer:
a i
[tex]P(X < 185 ) = 0.3085 [/tex]
a ii
[tex]P(X > 195 ) = 0.3085 [/tex]
a iii
[tex]P(185 < X < 195 ) = 0.3829 [/tex]
b
[tex]x = 208.8[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 190[/tex]
The standard deviation is [tex]\sigma = 10[/tex]
Generally the probability is less than 185 is mathematically represented as
[tex]P(X < 185 ) = P(\frac{X - \mu }{\sigma } < \frac{185 - 190 }{10 } )[/tex]
Generally [tex]\frac{X - \mu }{\sigma } = Z (The \ standardized \ value \ \ of \ X)[/tex]
=> [tex]P(X < 185 ) = P(Z< -0.5)[/tex]
From the z-table the p value of (Z< -0.5) is
[tex]P(Z< -0.5) = 0.3085[/tex]
So
[tex]P(X < 185 ) = 0.3085 [/tex]
Generally the probability is less than 185 is mathematically represented as
[tex]P(X > 195 ) = P(\frac{X - \mu }{\sigma } > \frac{195 - 190 }{10 } )[/tex]
=> [tex]P(X > 195 ) = P(Z > 0.5)[/tex]
From the z-table the p value of (Z > 0.5) is
[tex]P(Z > 0.5) = 0.3085[/tex]
So
[tex]P(X > 195 ) = 0.3085 [/tex]
Generally the probability is less than 185 is mathematically represented as
[tex]P(185 < X < 195 ) = P( \frac{185 - 190 }{10 } < \frac{X - \mu }{\sigma } < \frac{195 - 190 }{10 } )[/tex]
=> [tex]P(185 < X < 195 ) = P(-0.5 < Z > 0.5)[/tex]
=> [tex]P(185 < X < 195 ) = P(Z < 0.5 ) - P(Z < -0.5) [/tex]
From the z-table the p value (Z < 0.5) and (Z < -0.5) is
[tex]P(Z < 0.5) = 0.6915 [/tex]
and
[tex]P(Z < - 0.5) = 0.3085[/tex]
So
=> [tex]P(185 < X < 195 ) = 0.6915 - 0.3085 [/tex]
=> [tex]P(185 < X < 195 ) = 0.3829 [/tex]
Generally the level of cholesterol the 97th percentile represents is mathematically evaluated as
[tex]P(X < x ) = 0.97[/tex]
=> [tex]P(X < x ) = P(\frac{X - \mu}{\sigma } < \frac{x - 190}{10 } ) = 0.97[/tex]
=> [tex]P(X < x ) = P(Z < \frac{x - 190}{10 } ) = 0.97[/tex]
From the z-table the z-score for 0.97 is
[tex]z-score = 1.88[/tex]
=>
[tex]\frac{x - 190}{10 } = 1.88[/tex]

Two construction contracts are to be randomly assigned to one or more of three firms: I, II, and III. Any firm may receive both contracts. Each contract will yield a profit of $90,000. Assume that firms I and II are actually owned by the same individual. Find the probability distribution of X, the owner's total profit.
Answer:
The owner's total profit is $120,000.
Step-by-step explanation:
Assume that:
X₁ = contract is assigned to firm 1
X₂ = contract is assigned to firm 2
The sample space for assigning the two contracts is:
S = {(I, I), (I, II), (I, III), (II, I), (II, II), (II, III), (III, I), (III, II) and (III, III)}
There are total of 9 possible combinations.
So, the probability of selecting any of the combination is, 1/9.
Compute the probability distribution of X₁ and X₂ as follows:
X₁ P (X₁) X₂ P (X₂)
0 4/9 0 4/9
1 4/9 1 4/9
2 1/9 2 1/9
Compute the expected values of X₁ and X₂ as follows:
[tex]E(X_{1})=\sum X_{1}\cdot P(X_{1})\\\\=(0\times\frac{4}{9})+(1\times\frac{4}{9})+(2\times\frac{1}{9})\\\\=\frac{6}{9}\\\\=\frac{2}{3}[/tex] [tex]E(X_{2})=\sum X_{2}\cdot P(X_{2})\\\\=(0\times\frac{4}{9})+(1\times\frac{4}{9})+(2\times\frac{1}{9})\\\\=\frac{6}{9}\\\\=\frac{2}{3}[/tex]
It is provided that each contract will yield a profit of $90,000.
Compute the owner's total profit as follows:
[tex]\text{Total Profit}=\text{Profit}\times [E(X_{1})+E(X_{2})][/tex]
[tex]=90000\times[\frac{2}{3}+\frac{2}{3}]\\\\=120000[/tex]
Thus, the owner's total profit is $120,000.

he production of pipes has a mean diameter of 3.25 inches and a standard deviation of .15 inches. The shape of the distribution is approximated by a normal distribution since approximately an equal number of parts are above or below average, and most parts are very close to the mean value. A part will be discarded is it has a diameter of greater than 3.5 inches or less than 3 inches. What proportion of parts are discarded from the production line
Answer:
The probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Step-by-step explanation:
[tex]Mean = \mu = 3.25 inches[/tex]
Standard deviation = [tex]\sigma = 0.15 inches[/tex]
We are supposed to determine the probability that a randomly chosen part has diameter of 3.5 inches or more
[tex]P(Z \geq 3.5)=1-P(z<\frac{x-\mu}{\sigma})\\P(Z \geq 3.5)=1-P(z<\frac{3.25-3.5}{0.15})\\P(Z \geq 3.5)=1-P(z<-1.67)[/tex]
Refer the z table for p value
[tex]P(Z \geq 3.5)=1-0.0475\\P(Z \geq 3.5)=0.9525[/tex]
Hence the probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
f) graph the function in part e. (10 points)
Answer:
Step-by-step explanation:
Given: $1.99 as the fee per book (slope) & fixed fee of $3 (y-intercept)
The function can be written out f(x) = 1.99x + 3.
Express the value of f(x) for x = 0.
This would cancel out the slope, giving us a horizontal line on (0, 3).
f(0) = 1.99(0) + 3
f(0) = 3
You can try to graph the function using a software or by hand.
The graph is continuous because the x-values can have any input as a point.

A manufactured product has a length that is normally distributed with a mean of 12 cm. The product will be unusable if the length is 11 V2 cm or less.
Required:
a. If the probability of this has to be less than 0.01, what is the maximum allowable standard deviation?
b. Assuming this standard deviation, what is the probability that the product’s length will be between 11.75 and 12.35 cm?
Answer:
a) σ = 0,1612
b) P [ 11,75 < X < 12,35] = 0,92,44 or 92,44 %
Step-by-step explanation:
NOTE: I assume the unusable length s 11,5 and less
a) For a normal distribution, the probability of P = 0,01 corresponds to z(score) = -3,1 then:
- 3,1 = ( X - μ₀ ) / σ
- 3,1 = (11,5 - 12 )/ σ
-3,1 = - 0,5 / σ
σ = 0,1612
b) If σ = 0,1612
P [ 11,75 < X < 12,35]
z₁ (score) = ( 11,75 - 12 ) / 0,1612
z₁ = - 0,25/ 0,1612
z₁ = -1,55
From z table P [ 11,75 < X] = 0,0606
z₂ (score) = ( 12,35 - 12) / 0,1612
z₂ = 0,35 / 01612
z₂ = 2,17
From z table P [ X < 12,35] = 0,9850
Finally P [ 11,75 < X < 12,35] = 0,9850 - 0,0606
P [ 11,75 < X < 12,35] = 0,92,44 or 92,44 %

I will be giving out brainlist if the answer you submitted was correct❤️.
Please answer correctly and don’t waste my points these were hard to earn :((((
Answer:
Question 1: She had $352 in her wallet
Question 2: The percent of the trout were the tiger trout is 45%
Step-by-step explanation:
Question 1:
∵ Carmen spent $88 at the mall
∵ The money she spent was 25% of the total amount she had in her wallet
→ Assume that the amount she had in her wallet is $x
∴ 25% of x = 88
→ Change 25% to decimal by divide it by 100
∵ 25% = [tex]\frac{25}{100}[/tex] = 0.25
∴ 0.25 × x = 88
∴ 0.25x = 88
→ Divide both sides by 0.25 to find x
∴ [tex]\frac{0.25x}{0.25}=\frac{88}{0.25}[/tex]
∴ x = 352
∵ x represents the total amount she had in her wallet
∴ She had $352 in her wallet
Question 2:
∵ Kendrick caught 22 rainbow trout and 18 tiger trout while fishing
last month
∴ The number of rainbow trout = 22
∴ The number of tiger trout = 18
→ To find the percent of tiger trout divide its number by the total number
of trout, then multiply the result by 100%
∵ The total number of the trout = 22 + 18 = 40
∴ The percent of the tiger trout = [tex]\frac{18}{40}[/tex] × 100%
∴ The percent of the tiger trout = 45%
∴ The percent of the trout were the tiger trout is 45%

https://brainly.com/question/13741614
Answer:
With this algebraic representation of physics, we can also apply the mathmatical concept of quadratics to derive the components from this function. You can use the line of symmetry: x = -b/2a. To find the minimum or maximum height because of its association with the vertex. This function is in the standard quadratic form: ax^2 + bx + c where x is t. According to this instance, a being -16, b being 24, and c being 8. t = -b/2a → -24/-32 = 3/4 which also represents the maximum value because a is negative so it is opening downward.
To find the max height, substitute the value of x back into the equation f(3/4) = -16(3/4)^2 + 24(3/4) + 8 →
-9 + 18 + 8 = 17ft [maximum height]
We already solved for the time (x) in terms of t which is 3/4 sec [time of maximum height].

(E) More than 900 years
Answer:
The correct answer is:
Between 600 and 700 years (B)
Step-by-step explanation:
At a constant decay rate, the half-life of a radioactive substance is the time taken for the substance to decay to half of its original mass. The formula for radioactive exponential decay is given by:
[tex]A(t) = A_0 e^{(kt)}\\where:\\A(t) = Amount\ left\ at\ time\ (t) = 75\ grams\\A_0 = initial\ amount = 1000\ grams\\k = decay\ constant\\t = time\ of\ decay = 2500\ years[/tex]
First, let us calculate the decay constant (k)
[tex]75 = 1000 e^{(k2500)}\\dividing\ both\ sides\ by\ 1000\\0.075 = e^{(2500k)}\\taking\ natural\ logarithm\ of\ both\ sides\\In 0.075 = In (e^{2500k})\\In 0.075 = 2500k\\k = \frac{In0.075}{2500}\\ k = \frac{-2.5903}{2500} \\k = - 0.001036[/tex]
Next, let us calculate the half-life as follows:
[tex]\frac{1}{2} A_0 = A_0 e^{(-0.001036t)}\\Dividing\ both\ sides\ by\ A_0\\ \frac{1}{2} = e^{-0.001036t}\\taking\ natural\ logarithm\ of\ both\ sides\\In(0.5) = In (e^{-0.001036t})\\-0.6931 = -0.001036t\\t = \frac{-0.6931}{-0.001036} \\t = 669.02 years\\\therefore t\frac{1}{2} \approx 669\ years[/tex]
Therefore the half-life is between 600 and 700 years
The sum of two non-zero numbers a and b equals the sum of their reciprocals. If a+b≠0, what is the product of the two numbers?
Answer:
ab = 1
Step-by-step explanation:
A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.
So the reciprocal of x would be x⁻¹ or ¹⁄ₓ
The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.
So we can write this into an equation and solve,
(See image)
Once we solve, we get the equation (ab-1)(a+b) = 0
We are given info that a+b≠0
So for the above equation to be true, ab-1 has to equal 0
For this to be true, the product ab must equal 1
