Consider a set of 7500 scores on a national test whose score is known to be distributed normally with a mean of 510 and a standa
german
\mathbb P(X>600)=\mathbb P\left(\dfrac{X-510}{85}>\dfrac{600-510}{85}\right)=\mathbb P(Z>1.059)\approx0.145

So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see 0.145\times7500\approx10.86 scores above 600.

F is perpendicular to line m whats blank
erastova [34]
Hi, I would like to answer you question to help you out but unfortunately there is not enough information for me to do so. Maybe if you put a picture along with those words then I could solve the problem.

For example, when stating a problem such as 2 plus?= 4

Then I am able to solve by doing...

4-2=2

Check:
2 plus 2=4

But with your problem, F is perpendicular to line m whats blank

Then the only thing I am able to do is...

F=m
blank=?

Like I said I would love to help but I need a little more info than what is present now. Thanks.

Which number is not a perfect square?
bagirrra123 [75]

Answer:

C

Step-by-step explanation:

If I had to make a choice it would be C. Its strange because all numbers can be divided by 4 so they all can make a square. But the closest was C.

Solve the inequality below. Use the drop-down menus to describe the solution and its greah
Solnce55 [7]

Answer:

The solution of the inequality is x ≤ -4. A graph of the solution should have a vertical line passing through x = -4 and be shaded to the left of x = -4

Step-by-step explanation:

-7x + 13 ≥ 41

Subtract 13 from both sides

-7x ≥ 28

Dividing both sides by the -7 changes the inequality sign and we have

x ≤ -4

Hence, the solution of the inequality is x ≤ -4 and the graph of the solution should have a vertical line passing through x = -4 and it should be shaded to the left of x = -4 indicating that only numbers less than or equal to -4 are possible solutions of the inequality.

Hope this Helps!!!
