The social studies teacher wants to know whether the students in the entire school prefer a model United Nations activity or a student government activity. The teacher draws a random sample from the following groups: All teachers in the school All boys in each grade All students in each grade All students in the social studies club Which group best represents the population he should take a random sample from to get the best results for his survey? (5 points) Group of answer choices All teachers in the school All boys in each grade All students in each grade All students in the social studies club
Answer:
The social studies teacher should draw a random sample from all the students in each grade.
Step-by-step explanation:
The teachers will not be doing the activity, so their opinion is irrelevant. All boys in each grade targets a some audience and leaves the girl's voices unheard. All the students in the social studies club only represent a small portion of students who take the class. A poll of all the students in each grade will give the teacher the results they desire.

Is 600% of 9 less than 10, greater than 10 but less than 100, or greater than 100?
Answer:
Greater than 10, less than 100
Step by Step Explanation:
600%=6
Why? - because you move the decimal two places to the left when turning a percent into a fraction
So 600% of 9 is 6 times 9 which is 54
54 is greater than 10 but less than 100
I hope this helps!!!
Answer:
600% of 9 is greater than 10 but less than 100
Step-by-step explanation:
WHYTo find out whether 600% of 9 is less than 10, greater than 10 but less than 100, or greater than 100, we need to calculate the value of 600% of 9.
600% of 9 can be calculated as follows:
600% = 600/100 = 6
6 * 9 = 54
So, 600% of 9 is equal to 54.
Since 54 is less than 100 but greater than 10, the answer is that 600% of 9 is greater than 10 but less than 100.

can someone solve 9 = x - 5 + 8 STEP BY STEP PLEASE?
Answer:
x=6
Step-by-step explanation:
first, remember to simplify each side of the equation
so, 9=x+3, because -5+8=3
9=x+3
remember, you must isolate x by reversing the operation that is done on x
so, right now 3 is being added to x.
So, to reverse, you have to subtract 3, but remember, what is done to one side must be done to both
9=x+3

6=x

The perimeter of a rectangle is 40 feet its length is 12 feet what is the width
Answer:
8 feet
Step-by-step explanation:
In a rectangle
length (L) = 12 feet
perimeter (p) = 40 feet
width (b) = ?
We know
p = 2(L + b)
40 = 2 ( 12 + b)
40/2 = 12 + b
20 = 12 + b
b = 20 - 12
b = 8 feet
Answer:
12 feet
Step-by-step explanation:
Perimeter of rectangle = 2( l + b )
40 = 2( 12 + b )
40 = 24 + 2b
40 - 24 / 2 = b
12 feet = b (width)
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
Answer:
length of foot = y
length of forearm = x = 17
Equation: y = 0.860x + 3.302
Plug in 17 for x in the equation, and simplify. Remember to follow PEMDAS, first multiply, then combine like terms:
y = (0.860)(17) + 3.302
y = 14.62 + 3.302
y = 17.922
length of foot = y = 17.922 inches long
Step-by-step explanation:
If the forearm of a person is 17 inches long then his foot would be 17.922 inches long.
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
We have been given an equation y = 0.860x + 3.302
y = length of the foot and x = length of the forearm
The equation below can be used to find the length of a foot or forearm when you know one or the other.
We need to find the foot of a person be if his forearm was 17 inches long.
For x = 17 inches, we need to find the value of y.
Substitute x = 17 in the given equation.
⇒ y = 0.860x + 3.302
⇒ y = 0.860 (17) + 3.302
⇒ y = 14.62 + 3.302
⇒ y = 17.922
Therefore, if the forearm of a person is 17 inches long then his foot would be 17.922 inches long.

7. Danielle went to the grocery store to buy pies for a family dinner. The manager told her they were having a sale in which she could get the third pie for half price if she bought the first two for full price. Is the relationship between the number of pies and the cost proportional? JUSTIFY YOUR ANSWER
Answer:
No
Step-by-step explanation:
The relationship between the number of pies and the cost is not proportional. This is because the third pie is at half price, meaning it's not consistent with the price of the other two.

Sweet Springs Candy Shop sold 2 pounds of chocolates for $9.98 and 5 pounds of chocolate for $24.95.
A. Is the relationship between the number of pounds of chocolate and the total cost proportional?
B. Why or why not?
Answers:
A) Yes, the total cost is proportional to the number of pounds of chocolate.B) Explanation is below=================================================
Let,
x = number of pounds of chocolate
y = cost of buying x pounds of chocolate
If you buy x = 2 pounds, then you spend y = 9.98 dollars.
So k = y/x = 9.98/2 = 4.99 is the cost per pound. This is known as the unit price or unit cost. It's the cost of one pound of chocolate.
Now if you buy x = 5 pounds, then you'll be charged a total of y = 24.95
So, k = y/x = 24.95/5 = 4.99
We get the same constant of proportionality here, and therefore, this is a direct proportional relationship. Each time x goes up by 1, y goes up by 4.99; in other words, each time you buy 1 extra pound of chocolate, you pay $4.99 more. This is to be expected whenever you're at the grocery store as long as you ignore things like coupons or bulk discounts or things of that nature.
The equation of this line is y = 4.99x
This shows the slope is 4.99 and the y intercept is 0.
------------------
An alternative approach:
Again we define x and y as stated above. We see that the two points are (2,9.98) and (5,24.95)
Computing the slope gets us
m = (y2-y1)/(x2-x1)
m = (24.95-9.98)/(5-2)
m = 14.97/3
m = 4.99
So this matches what we got earlier.
Now turn to y = mx+b. Plug in that value of m along with (x,y) = (2,9.98)
Doing so gets us 9.98 = 4.99*2+b
Let's solve for b
9.98 = 4.99*2+b
9.98 = 9.98+b
0 = b
b = 0
I subtracted 9.98 from both sides to isolate b. The fact we get the y intercept is 0 helps show that we have a direct proportion. All direct proportion linear equations go through the origin (0,0). This is to reflect that buying 0 pounds of chocolate means you pay 0 dollars.
We get the same result as the previous section.
