d. He should use the paired-sample of the mean to answer question one and two sample test of the mean to answer question two.
Answers
Answer:
b. He should use the two-sample test of the mean to answer question one and the two-sample test of proportion to answer question two.
Step-by-step explanation:
Here we have two independent groups, Men and Women, therefore, to show if it is the Men or Women who performed better, this can be determined based the mean scores of each group. Therefore, use the two sample test of mean which is used to test whether the unknown mean of two independent population are equal or not.
In other to determine those who have the greater number of admissions between the two groups, this is determined by comparing the proportion of each group admitted. Hence, rather Than testing for the mean, we compare the proportion. Hence, we use the two sample test of proportion.

What is the area of this rectangle? Rectangle with width 5.1 cm and height 11.2 cm. Responses 16.3 cm2 16.3 cm, 2 32.6 cm2 32.6 cm, 2 57.12 cm2 57.12 cm, 2 571.2 cm2
Answers
The area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².
To find the area of a rectangle, we multiply its length by its width. In this case, the width is given as 5.1 cm and the height (or length) is given as 11.2 cm.
Area = length × width
Area = 11.2 cm × 5.1 cm
Calculating the product, we get:
Area = 57.12 cm²
Therefore, the area of the rectangle is 57.12 cm².
The correct answer is: 57.12 cm².
It is important to note that when calculating the area of a rectangle, we should always include the appropriate unit of measurement (in this case, cm²) to indicate that we are dealing with a two-dimensional measurement. The area represents the amount of space covered by the rectangle's surface.
So, the area of a rectangle with a width of 5.1 cm and a height of 11.2 cm is 57.12 cm².

which grows at the fastest rate for increasing values of x
\(f(x)=4*2^x\\h(x)=9x^2+25\\\\g(x)=15x+6\)
Answers
The function that grows at the fastest rate for increasing values of x is f(x) = 4×2ˣ.
We can see this by comparing the growth rates of the three functions for larger and larger values of x.
As x gets larger, the exponential function f(x) grows much faster than the other two functions, which are both polynomial functions.
if we plug in x = 10, we get:
f(10) = 4×2¹⁰ = 4×1024 = 4096
h(10) = 9×10² + 25 = 925
g(10) = 15×10 + 6 = 156
As we can see, f(10) is much larger than h(10) and g(10), indicating that f(x) grows at a much faster rate than the other two functions.

Students in a large statistics class were randomly divided into two
groups. The first group took the midterm exam with soft music
playing in the background while the second group took the exam
with no music playing. The exam scores of the two groups were
then compared.
This experiment was not blind because:
- students were allowed to keep their eyes open while
taking the exam.
- the exam was too long.
- the students knew whether or not music was playing while
they were taking the exam.
- some of the students did not study for the exam.
- students were randomized into the two groups.
Answers
The correct option is B. The students knew whether or not music was playing while they were taking the exam
Given,
The class was split into two groups.
The first group took the midterm exam while background music was playing, and the second group took the exam without any background music.
In a blind experiment, any information that might affect the subjects is kept secret until the experiment is over. The pupils in this instance are aware of their group membership.
In order to answer this question, an experiment is carried out to see how music affects learning. One group of students studies while background music is playing, while the other group does not.
However, because of the background music playing here, the pupils are aware of which group they belong to. The experiment's outcomes are impacted by this.
Therefore the correct option is B. The students knew whether or not music was playing while they were taking the exam.

Write an equation for the line parallel to the line -7x - 7y= 7 through the point (-1,2)
Answers
Answer:
\(y=-x+1\)
Step-by-step explanation:
Slope-Intercept Formula:It helps to write the equation in slope-intercept formula to find the slope of an equation in the form: \(y=mx+b\) where "m" is the slope of the equation. We can take the equation given: \(-7x-7y=7\) and solve for "y" to get the equation in slope-intercept form:
\(-7x-7y=7\)
add 7x to both sides:
\(-7y=7x+7\)
Divide both sides by -7
\(y=-x-1\)
Now in this form we can tell that the coefficient of "x" (the m value) is our slope, which is -1. We need this slope to determine a parallel line as parallel lines share the same slope but different y-intercepts. So a general equation for a parallel line would be:
\(y=-x+b\text{ where b }\ne -1\)
We're given the point (-1, 2) and we can use it to solve for that "b" value.
We plug in -1 as x and 2 as y
\(2=-1(-1)+b\implies 2=1+b\implies 1=b\)
Now we just plug this into the general equation to get: \(y=-x+1\)

Answers
Given the exponential function:
\(f(x)=a\cdot b^x\)The function passes through the points:
(0, 4) and (3, 500)
Let's find the values of a and b.
Let's use the given points to find a and b.
(0, 4):
Substitute 0 for x, and 4 for f(x), to find the value of a:
\(\begin{gathered} f(x)=a\cdot b^x \\ \\ 4=a\cdot b^0 \\ \\ 4=a\cdot1 \\ \\ 4=a \\ \\ a=4 \end{gathered}\)The value of a is 4
(3, 500):
Substitute 3 for x, 500 for f(x) and 4 for a to solve for b:
\(\begin{gathered} f(x)=a\cdot b^x \\ \\ 500=4\cdot b^3 \\ \\ \text{Divide both sides by 4:} \\ \frac{500}{4}=\frac{4\cdot b^3}{4} \\ \\ 125=b^3 \\ \\ \text{Take the cube root of both sides:} \\ \sqrt[3]{125}=\sqrt[3]{b^3} \\ \\ 5=b \\ \\ b=5 \end{gathered}\)The value of b is 5

Step-by-step explanation:
Hi there.

1b. m P= 60 degrees
10+110=120 180-120=60
For future reference, you can solve these with some simple addition. The sum of the angles in any triangle is 180, so add your two given pieces together and subtract it from that to get your missing measure.
2a. Lines a and b have a positive slope. You can tell because they are tilted to the right.
2b. Line d has a negative slope. It's tilted to the left.
(Line c's slope is neither positive or negative because it is zero)
3. x= 65
(I'm not so sure about this one, but I think the angle opposite 25 is also 25, and because of parallel rules the angle above 70 is 110. That means the angle above 110, inside the triangle, is 90. So, we have 90 and 25 and that means 65 is our remaining measure. I really hope this is correct. If you have some sort of notes sheet on the rules of parallel lines and their angle measures, that might be helpful)

A small class has 9 students, 4 of whom are girls and 5 of whom are boys. The teacher is going to choose two of the students at random. What is the probability that the first student chosen will be a boy and the second will be a girl? Write your answer as a fraction in simplest form.
Answers
The probability that the first student chosen will be a boy and the second will be a girl is 0.28.
What is probability?Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Total students = 9
Number of girls = 4
Number of boys = 5
Probability of choosing first boy = Number of boys / total students
⇒ 5/9
Now since 1 boy extract so remaining students = 9 - 1 = 8
Probability of choosing second girl = Number of girls / Total students
⇒ 4//8
Probability of A and B = P(A) × P(B)
Therefore,
The probability that the first student chosen will be a boy and the second will be a girl = (5/9) × (4/8) = 0.28
Hence "The probability that the first student chosen will be a boy and the second will be a girl is 0.28".

if a to b ratio, b to c ratio, c to d ratio, are given, then express a to d in terms of given ratios
Answers
The ratio of a to d can be expressed by multiplying the ratio of a to b, b to c, and c to d. Therefore, a to d = (a to b) x (b to c) x (c to d).
The ratio of a to d can be determined by using the given ratio of a to b, b to c, and c to d. To begin, the ratio of a to b can be expressed as a:b, the ratio of b to c can be expressed as b:c, and the ratio of c to d can be expressed as c:d. Then, the ratio of a to d can be determined by multiplying the ratios of a to b, b to c, and c to d. This can be written as (a:b) x (b:c) x (c:d). Therefore, the ratio of a to d can be expressed as (a:b) x (b:c) x (c:d). For example, if the ratio of a to b is 2:3, the ratio of b to c is 4:5, and the ratio of c to d is 6:7, then the ratio of a to d would be (2:3) x (4:5) x (6:7) or 24:35.
