For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric
temperature can be described by the formula t = -0.0035a +g, in which t is the atmospheric
temperature in degrees Fahrenheit,a is the altitude, in feet, at which the atmospheric temperature is
measured and g is the ground temperature in degrees Fahrenheit. Solve the equation for a. If the
atmospheric temperature is -30.5 °F and the ground temperature is 50 °F, what is the altitude?
The equation for a is a =
If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then

Answer:
The equation for a is [tex]a=-\frac{2000}{7}*(t-g)[/tex]
The altitute is 101,428.57 feet
Step-by-step explanation:
You know that the relationship between ground temperature and atmospheric temperature can be described by the formula
t = -0.0035a +g
where:
t is the atmospheric temperature in degrees Fahrenheita is the altitude, in feet, at which the atmospheric temperature is measured g is the ground temperature in degrees Fahrenheit.Solving the equation for a:
-0.0035a +g=t
-0.0035a= t - g
[tex]a=\frac{t-g}{-0.0035}[/tex]
[tex]a=-\frac{2000}{7}*(t-g)[/tex]
The equation for a is [tex]a=-\frac{2000}{7}*(t-g)[/tex]
If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F
Replacing in the equation for a you get:
[tex]a=-\frac{2000}{7}*(-305-50)[/tex]
[tex]a=-\frac{2000}{7}*(-355)[/tex]
a= 101,428.57
The altitute is 101,428.57 feet

A newspaper article states that 90% of drivers in Iowa wear their seatbelt. Suppose we are interested in estimating the proportion of drivers in Iowa City who wear their seatbelt when driving. We will observe drivers at different times of the day at different locations around town and record whether they are wearing their seatbelt. How large of a sample would we need to estimate this proportion to within 1% with 95% confidence?
Answer:
The sample size is [tex]n = 3457 [/tex]
Step-by-step explanation:
From the we are told that
The population proportion is p = 0.90
The margin of error is E = 0.01
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally the sample size is mathematically represented as
[tex]n =[ \frac{ Z_{\frac{\alpha }{2} } }{E} ]^2 * p(1-p)[/tex]
=> [tex]n =[ \frac{ 1.96 }{0.01} ]^2 * 0.90(1-0.90)[/tex]
=> [tex]n = 3457 [/tex]

Answer:
4,757 pounds
Step-by-step explanation:
One case book weighs 34 pounds
One case of magazines weigh 25 pounds
A book store wants to ship 73 cases of book 91 cases of magazines
Therefore the total weight of the shipment can be calculated as follows
= 34×73 + 25×91
= 2482 + 2275
= 4,757
Hence the total weight of the shipment is 4,757 pounds

2. Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy individuals are Normally distributed, with a mean of 3.2 mg/dl and a standard deviation of 1.5 mg/dl. A researcher believes that one area of the United States has naturally elevated arsenic levels in the ground and water supplies. An SRS of 25 individuals in this area found a sample mean arsenic level of 3.75 mg/dl. What are the null and alternative hypotheses for this study?
Answer:
The null hypothesis [tex]H_o : \mu = 3.2 \ mg/dl[/tex]
The alternative hypothesis [tex]H_a : \mu > 3.2 \ mg/dl[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 3.2 \ mg/dl[/tex]
The standard deviation is [tex]\sigma = 1.5 mg/dl[/tex]
The sample size is n = 25
The sample mean is [tex]\= x = 3.75 \ mg /dl[/tex]
Generally
The null hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is [tex]\mu = 3.2 \ mg/dl[/tex]
i.e
The null hypothesis [tex]H_o : \mu = 3.2 \ mg/dl[/tex]
The alternative hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is greater than [tex]\mu = 3.2 \ mg/dl[/tex]
The alternative hypothesis [tex]H_a : \mu > 3.2 \ mg/dl[/tex]

b
[tex]P(J) = 0.27 [/tex]
c
[tex]P(R) = 0.0144 [/tex]
d
[tex]P(R') = 0.7744 [/tex]
e
[tex]P(Q) =0.2256 [/tex]
Step-by-step explanation:
From the question we are told that
The proportion of M & M's that is brown is b = 0.12
The proportion of M & M's that is yellow is y = 0.15
The proportion of M & M's that is red is r = 0.12
The proportion of M & M's that is blue is b = 0.23
The proportion of M & M's that is orange is o = 0.23
The proportion of M & M's that is green is g = 0.15
Generally the probability that a random selected M&M is not yellow is
[tex]y' = 1-y[/tex]
=> [tex]y' = 1-0.15[/tex]
=> [tex]y' = 0.85 [/tex]
Generally the probability that a randomly selected peanut M&M isgreen or red is mathematically represented as
[tex]P(J) = g + r [/tex]
=> [tex]P(J) = 0.15 + 0.12 [/tex]
=> [tex]P(J) = 0.27 [/tex]
Generally the probability that two randomly selected peanut M&M’s are both red is mathematically represented as
[tex]P(R) = r^2[/tex]
=> [tex]P(R) = 0.12^2[/tex]
=> [tex]P(R) = 0.0144 [/tex]
Generally if two two peanut M&M’s are selected the probability that neither of them are red is mathematically represented as
[tex]P(R') = (1 -r)^2[/tex]
=> [tex]P(R') = (1 - 0.12)^2[/tex]
=> [tex]P(R') = 0.7744 [/tex]
Generally if two two peanut M&M’s are selected the probability that at least one of them is red is mathematically represented as
[tex]P(Q) = 1- P(R')[/tex]
=> [tex]P(Q) = 1- 0.7744 [/tex]
=> [tex]P(Q) =0.2256 [/tex]

The resting heart rates for a sample of individuals are normally distributed with a mean of 70 and a standard deviation of 15. Use the 68-95-99.7 rule to find the percentage of heat rates greater than 55
Answer:
84%
Step-by-step explanation:
The empirical rule states that 68% values are within 1 standard deviation of mean, i.e,
70
±
15
or from 55 to 85. Since normal distribution is symmetric, we must have (32%) outside this range, and 32/2=16% on the right if this range. Hence below 85 we have (100-16) % = 84%

Substitute values
[tex]Area = \frac{1}{2}[(-5*4 +3*-6 + 6*-6 + -7*4)-(3*4 +6*4 + -7*-6 + -5*-6)][/tex]
[tex]Area = \frac{1}{2}[(-102)-(108)][/tex]
[tex]Area = \frac{1}{2}[-102-108][/tex]

Solving the for angle NMP. *
Answer:
50°
Step-by-step explanation:
Angle NMP is an angle that has its vertex on a point along the circumference of the circle, thus, angle NMP is referred to as an inscribed angle of the circle.
The measure of an inscribed angle is equal to half of the measure of the arc it intercepts.
Therefore, the following equation shows the relationship between inscribed angle NMP and arc NP:
m<NMP = ½ × measure of arc NP
m<NMP = ½*100
m<NMP = 50°
Anna is 9 years less than twice jims age. The sum of thier ages are 63. how old are anna and jim
Answer:
Jim is 36. Anna is 27.
Step-by-step explanation:
63 -9 = 54
54 ÷ 2 = 27
27 + 9 = 36
Anna's age is 39 years old while Jim's age is 63-year old based on the formation of the equation for their age.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's say Anna's age is A while Jim's age is J.
As per the given,
Anna is 9 years less than twice Jim's age.
A = 2J - 9
And,
Sum A + J = 63
By solving both equations,
63 - J = 2J - 9
63 + 9 = 3J
J = 24 years old.
A = 2(24) - 9 = 39 years old.
Hence "Anna's age is 39 years old while Jim's age is 63-year old based on the formation of the equation for their age".

homework
, and takes another 1/4hour to do chores every day. How much
longer does Naruto spend practicing his harmonica and doing his chores
than working on homework?
Answer:
2
Step-by-step explanation:
If he uses 1 hour to practice harmonica, one our on homework, and another hour doing chores. He will be spending twice as much time practicing harmonica and doing homework than he would spend on chores.
Answer:
10 minutes more on working with his homework than his chores and harmonica OR 1/6 hour (or any other equivalent fraction).
Step-by-step explanation:
You can convert 1/4 into fifteen minutes. 15+15=30 minutes. Thus, he spends 30 minutes on his harmonica and doing chores.
You can convert 2/3 into 40 minutes.
40-30=10, so he spent 10 minutes more on working with his homework than his chores and harmonica.
Since you want it in fractions, you can find fractions that are equivalent to 10/60. One you can use is 1/6.

8) A committee has fifteen members. There are two members that currently serve as the board’s chairman and vice chairman. Each member is equally likely to serve in any of the positions. Two members are randomly selected and assigned to be the new chairman and vice chairman. What is the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions
Answer:
The probability is [tex]P(Z) = 0.0064 [/tex]
Step-by-step explanation:
From the question we are told that
The number of members is n = 15
Generally the number of ways of selecting two member from the fifteen members is mathematically represented as
[tex]K = ^{n}C_2 * 2![/tex]
Here C stands for combination hence we will be making use of the combination functionality in our calculator
[tex]K = ^{15}C_2 * 2 * 1 [/tex]
=> [tex]K = 78 * 2 * 1 [/tex]
=> [tex]K = 156 [/tex]
Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1
Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as
[tex]P(Z) = \frac{m}{K}[/tex]
=> [tex]P(Z) = \frac{1}{156}[/tex]
=> [tex]P(Z) = \frac{1}{156}[/tex]
=> [tex]P(Z) = 0.0064 [/tex]
