From the question, we have:

September = 99th percentile
February = 90th percentile

A change (whether higher or lower) in the score is caused by statistical regression.

This is so because several variables could attribute to the change in the score.

The relationship between these variables is referred to as statistical regression

Asap help.! Circle measurements

Margaret [11]

Answer:

D

Step-by-step explanation:

Here, we want to get the value of x;

To get this, we simply use one of the circle angle and arc properties

Mathematically;

arc MN = 2 * arc MLN

3x + 22 = 134/2

That will be;

3x + 22 = 67

3x = 67-22

3x = 45

x = 45/3

x = 15

Answer: $\frac{485}{ 1,454}$

Step-by-step explanation:

For this exercuse you need to analize the information provided. You know that:

1) The height of the replica of the Empire State Building with its antenna spire in Las Vegas is 485 feet.

2) The height of the real Empire State building is 1,454 feet.

Finally, in order to find the ratio of height of the replica to the height of the real Empire State building, its necessary to divide the height of the replica of the Empire State Building by the height of the real Empire State building.

Therefore, trough this procedure you get that the ratio of height of the replica to the height of the real Empire State building is:

$ratio=\frac{heigth_{ replica}}{heigth_{real}}=\frac{485}{ 1,454}$

(This fraction cannot be reduced)
