a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?
Answers
The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.
So, the confidence interval is:
178.6 ± 45.2
To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:
(178.6 + (178.6 - 45.2)) / 2 = 311.6
Therefore, the estimated number of students per grade level in the state is 311.6

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4
Answers
1. First, divide both sides of the equation by 4.
1÷4 x³/4 = –27/4/4
2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.
3. Then, to solve for x, take the cube root of both sides of the equation.
Cube root of x³ = cube root of –27
4. To check your answer, plug in -3 for x in the original equation and solve.
1÷4 x³ = –27/4
1÷4 (-3)³ = –27/4
1÷4 (-27) = –27/4
1 = 1
Since 1 = 1, the answer checks out.
Therefore, the solution to the equation is x = -3.

The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

Drag each expression to show whether it is equivalent to 36x+9
or 9(4x−1)
.
Answers
In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E.
Next we will look at the expression 9(4x-1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9.
9 × 4x - 9
Now calculate the product
36x - 9
This means that the equivalent for this expression is
36x - 9,, or option A.
Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together.
(36x) + (4 × 2)
Now multiply the numbers in the second parenthesis together.
(36x) + 8
Remove the parenthesis
36x + 8
Now factor out 4 from the expression to get your final answer.
4(9x + 2)
This means that the last expression is equivalent to 4(9x + 2),, or option C.

That gave me -16/-12, I simplified & got 4/3.
To find the slope you need at least two points on a line

The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.
as the graph can not be used:
Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.
However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.
