one student chosen at random from each grade level an equal number of students chosen at random from each grade level the first 10 students from each grade level to arrive at school in the morning all students arriving on one busthe answer is: an equal number of students chosen at random from each grade level
Step-by-step explanation:
A good sample must be random and representative of all the population. In this case, the population is all the kids that go to middle school. A good sample would need to be taken at random and all the students should have equal opportunity to be chosen, and the three grades must be included in the same proportion.
Answer:

Traverion wants to find the answer to the question "How much money does the average college professor make?" He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university
Step-by-step explanation:
Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.
Therefore for him to have accurate result he have to survey professors from different area which will inturn give him the accurate sample

A)There is no bias in this survey because the students were randomly chosen.
B)There is nonresponse bias because the results underestimate the true percentage of students who complete their homework nightly.
C)There is response bias because the results underestimate the true percentage of students who complete their homework nightly.
D)There is convenience sampling bias because the results overestimate the true percentage of students who complete their homework nightly.
E)There is voluntary response bias because the results overestimate the true percentage of students who complete their homework nightly.

This relation is not a function because the number 6 repeats twice.
Riemann hypothesis, explain please.
Answer:
The Riemann Hypothesis states that all non trivial zeros of the Riemann zeta function have a real part equal to 0.5. ... The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Answer:
Y=X+74
Step-by-step explanation:
75=m+b......*
76=2m+b.........**,b=76-2m
then substitute b=76-2m
on the first equation
75=m+76-2m
m=1
b=74
Y=X+74 is the answer
Write the equation of the line that is parallel to y = -x – 5 and has a y-intercept at (0, 11).
Answer:
[tex]y=-x+11[/tex]
Step-by-step explanation:
We know that the new equation must be parallel to [tex]y=-x-5[/tex].
Therefore, since they are parallel, the slope of the new equation must be the same as the old.
The slope of the original equation is -1.
Therefore, the slope of our new equation is also -1.
We also know that it has a y-intercept at (0, 11).
And as determined earlier, it has a slope of -1.
So, we can use the slope-intercept form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
We will substitute -1 for m and 11 for b. Thus, our equation is:
[tex]y=-x+11[/tex]
Solve using substitution.
4x - 5y = 1
x = -6
Answer:
y = -5
Step-by-step explanation:
To solve by using substitution, first substitute x for -6 in the equation 4x-5y=1
4(-6)-5y=1 start by simplifying this problem
-24-5y=1 now you can solve for y, add 24 on both sides
-5y=25 now divide -5 on both sides
y= -5
A recipe requires 1 cup of milk for every 4 cups of flour. Choose a linear equation that describes the proportional relationship?
A- y=4x
B- y=4x+1/4
C-y=1/4x+4
D-y=1/4x
Answer:
A
Step-by-step explanation:
For every 4 cups of flour, there is one cup of milk, therefore, the first equation describes the relationship.
Michael says that 5(153)=5(53). Is his answer correct? Explain. A. Yes; Both expressions are equal to 625. B. Yes; Both expressions are equal to 125⋅ C. No; The first expression is equal to 125 and the second expression is equal to 625. D. No; The first expression is equal to 625 and the second expression is equal to 125.
Answer:
Michael's answer is not correct
5(153)≠ 5(53)
Step-by-step explanation:
Michael says that 5(153)=5(53)
Is his answer correct?
We solve for the left hand side
5(153) = 5 × 153
= 765
Solving for the right hand side
= 5(53) = 5 × 53
= 265
Therefore, from the above calculation,
5(153)≠ 5(53)
5(153) is not equal to 5(53)
Michael's answer is not correct

The seventh grade enrollment at Goddard increase from 380 to 456 students. What is the percentage of increase?
Answer:
The percentage of increase is minus.
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
If it increased from 380 to 456, first you need to find the difference.
456 - 380 = 76
Now, you must divide the original number by 76, which is 380.
76/380 = 0.2
Convert 0.2 to a percentage.
0.2 = 20%
The seventh grade enrollment at Goddard increased by 20%.
I hope it all works out well for you in your class :)
