The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which
Step2247 [10]

Answer:

D

Step-by-step explanation:

The mean will be the very middle of the distribution, which is at 66. So we know that a and c are wrong.

The standard deviation is the distance between those bars, like 70 and 74. 74-70 = 4, so the standard deviation is probably around 4.

That means the answer is D.

After solving the equation we get y=2 when x = 15

Step-by-step explanation:

We need to complete the solution of the equation -x-8y=-1

We need to find value of y when x equals -15

For finding value of y, we will put value of x= -15 in the given equation:

-x-8y=-1

-(-15)-8y=-1

+15-8y=-1

Adding -15 on both sides

-8y=-1-15

-8y=-16

Divide both sides by -8

y=2

So, After solving the equation we get y=2 when x = 15
