Suppose that a normal distribution has a mean of 20 and a standard deviation of 4.
What is the s-score of 13
Answer:
-1.75
Step-by-step explanation:
The z-score = (n - m) / d where n is the value (13) m = mean and d = standard deviation.
= (13 - 20) / 4
= -1.75 (answer)

Which inequality has the graph shown below?

y < 2x – 3
y > 2x - 3
y > 2x - 3
Answer:
the second option y<2x-3. how i know its collect because i used desmos
The inequality that the graph has shown is
y < 2x - 3
Option B is the correct answer.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
From the graph, we have the following coordinates.
(0, -3) and (1.5, 0)
The coordinates can be found in the following inequalities.
Now,
y < 3x + 1
y = 3x + 1
When x = 0, y = 1
This is not possible.
y < 2x – 3
y = 2x - 3
When x = 0, y = -3
This is possible.
y > 2x - 3
y = 2x - 3
When x = 0, y = -3
This is possible
The shaded portion of the graph is more on the negative y-axis.
So,
y < 2x - 3.
Thus,
The graph given has shown y < 2x - 3.

Now there is a door whose height is more than its width by 6 chi 8 cun. The distance between the [opposite] corners is 1 zhang. Find the height and width of the door.NOTE: 1 zhang
Complete question is;
Now there is a door whose height is more than its weight by 6 chi 8 cun. The distance is between the opposite is corners is 1 zhang. Find the height and width of the door.
Note: 1 zhange = 10 chi = 100 cun. Give your answers in units of chi and cun.
Answer:
h = 9 chi 6 cun
w = 2 chi 8 cun
Step-by-step explanation:
Let the height be h and width be w.
Now, we are told that height is more than its weight by 6 chi 8 cun.
Thus,
weight = height - 6 chi 8 cun
Let's convert 6 chi 8 cun to chi for easy calculation.
Since 100 cun = 10 chu
Then 8 cun = 8 × 10/100 = 0.8 chi
Thus 6 chi 8 cun = 6 chi + 0.8 chi = 6.8 chi
Thus;
Height is h
Width is (h - 6.8) chi
Now, we are told that the distance between the corners is 1 zhang = 10 chi
Distance between corners is the diagonal of the door.
Thus, the height, width and diagonal con form a right angle triangle which can be solved by Pythagoreas theorem.
Thus;
h² + w² = 10²
Plugging in (h - 6.8) for w, we have;
h² + (h - 6.8)² = 100
h² + h² - 13.6h + 46.24 = 100
2h² - 13.6h + 46.24 - 100 = 0
2h² - 13.6h - 53.76 = 0
Using quadratic formula, we have;
h = 9.6 chi
Converting 0.6 chi to cun gives;
0.6 × 100/10 = 6 cun
Thus, h = 9 chi 6 cun
Since w = (h - 6 chi 8 chun)
Then, w = 9 chi 6 cun - 6 chi 8 chun = 2 chi 8 chun
Which graph represents the function y = cos(4x)?
Answer is graph B
Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude = [tex]\frac{1-(-1)}{2}[/tex]
= 1
B = [tex]\frac{2\pi}{\text{Period}}[/tex]
B = [tex]\frac{2\pi}{\frac{\pi}{2}-0}[/tex]
B = [tex]\frac{4\pi}{\pi}[/tex]
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)

What is the additive inverse of -10? Explain how you know.
(Will name brainiest)
Answer:
The answer would be positive 10 this is because the additive inverse is the same number but different sign which yours is a negative sI it is positive 10.
Answer:
10
Step-by-step explanation:
The additive inverse of - 10 is 10.
Additive inverse are basically the opposites of the number so all you need to do is switch the signs. In this case, you have to switch -10 to its opposite, which is 10.
To check -10 + 10 = 0.
Jenna was on a 268 mile long road trip. During the first part of the trip there was lots of traffic so she only averaged 28 mph. The second part of the trip there was no traffic so she could drive 46 mph. She spent 1 hour longer after the traffic cleared than stuck in traffic. How long did she travel at each speed?
In traffic, she drove for______hours. After the traffic cleared, she drove for_____hours
Answer:
Step-by-step explanation:
It takes 36 minutes less time to travel 120 miles by car at night than by day because the lack of traffic allows the average speed at night to be 10 miles per hour faster than in the daytime. Find the average speed ,

If an AaBbccDd individual is crossed to a AaBbCcDD individual, what is the probability that the first offspring will be of AabbccDd genotype?
Answer:
The probability that the first offspring will be of AabbccDd genotype is 0.03125.
Step-by-step explanation:
The parents genotype are: AaBbccDd and AaBbCcDD.
Aa and AaA a
A AA Aa
a Aa aa
P (Aa) = 2/4 = 1/2
Bb and BbB b
B BB Bb
b Bb bb
P (bb) = 1/4
Cc and ccc c
C Cc Cc
c cc cc
P (cc) = 2/4 = 1/2
Dd and DDD d
D DD Dd
D DD Dd
P (Dd) = 2/4 = 1/2
Then the probability that the first offspring will be of AabbccDd genotype is:
P (AabbccDd) = (1/2) × (1/4) × (1/2) × (1/2) = 1/32
Thus, the probability that the first offspring will be of AabbccDd genotype is 0.03125.

What is a triangle?A polygon with three vertices, angles and sides is called a triangle.
Given that, a triangle △ LMN, where, ∠ M ≅ ∠ L, LM = 7 and LN = 16
Since, ∠ M ≅ ∠ L
Therefore, MN ≅ LN
By the postulate :-
Sides opposite to congruent angles of a triangle are also congruent.
Therefore,
MN = LN
Since, LN = 16
Therefore, MN = 16 [By transitive property]

box with a square base and open top must have a volume of 4,000 cm3. Find the dimensions of the box (in cm) that minimize the amount of material used. sides of base
Answer:
Hence the width, length is 20 cm and height is 10 cm
Step-by-step explanation:
Since the box has a square base, let length = width = x. Also, let the height = y, therefore:
The volume of box = width * length * height
4000 = x * x * y
4000 = x²y
y=4000/x²
The surface area (SA) = area of the base + sum of the area of each side
SA = x² + xy + xy + xy + xy
SA = x² + 4xy
substitute y = 4000/x²
SA = x² + 4x(4000/x²)
SA = x² + 16000/x
Taking the derivative:
SA' = 2x - 16000/x²
making SA' = 0:
0 = 2x - 16000/x²
2x = 16000/x²
2x³ = 16000
x³ = 8000
x = 20 cm
y = 4000 / x² = 4000 / 20² = 10 cm
Hence the width, length is 20 cm and height is 10 cm

0.5x + 1.75 = 10 and last one is
0.75h + 3 = 12
Answer:
13, 16.5, 12
Step-by-step explanation:
-7x= -91 divide both sides by -7 to isolate x
[tex]\frac{-7}{-7} x=\frac{-91}{-7}[/tex] any number divided by itself like in -7/-7 =1
x=13
0.5x + 1.75 = 10 subtract 1.75 from both sides
0.5x +1.75-1.75 =10 -1.75
0.5x = 8.25 divide by 0.5 both sides
[tex]\frac{0.5}{0.5} x=\frac{8.25}{0.5}[/tex]
x=16.5
0.75h +3=12 subtract 3 from both sides
0.75h = 12-3 divide both sides by 0.75
[tex]h= \frac{9}{0.75}[/tex] = 12

A. The sample size
B. The test statistic
C. The sample standard deviation
D. The number of degrees of freedom
The value of df is _________ Type an integer or a decimal. Do not round )
Answer:
D. The number of degrees of freedom
The value of df is 31
Step-by-step explanation:
Degrees of freedom (DF) denotes the amount of information provided by the data you can "consume" to estimate unknown population parameters' values and calculate the variability of those estimates.
Increasing the sample size provides more information about the population, which increases the degrees of freedom present in the data.
Given that:
The sample size in the study (n) = 32
The degree of freedom df = n - 1
The degree of freedom df = 32 - 1
The degree of freedom df = 31
