Given: AG and IC are common internal tangents of H and B. HI = 8, ED = 2, and EF = ED. What is the measure of AE?
ki77a [65]
AE = 6

This is because ABE is a right triangle with the right angle being angle BAE. We know that AB = 8 and EB = 10, so we can use the Pythagorean Thoerem to find AE.

The Environmental Protection Agency records data on the fuel economy of many different makes of cars. Data on the mileage of 20
artcher [175]

Answer:

A) 8.5 miles per gallon

Step-by-step explanation:

Given

x = \{12\ 13\ 15\ 16\ 16\ 17\ 18\ 18\ 19\ 19\ 20\ 20\ 22\ 23\ 24\ 26\ 26\ 27\ 27\ 29\}

n = 20

Required

The IQR

This is calculated as:

IQR = Q_3 - Q_1

Calculate Q_1

Q_1 = \frac{1}{4}(n + 1)th

Q_1 = \frac{1}{4}(20 + 1)th

Q_1 = \frac{1}{4}(21)th

Remove bracket

Q_1 = 5.25th

This means that:

Q_1 is the mean of 5th and 6th item

From the given data:

5th \to 16

6th \to 17

So, we have:

Q_1 = \frac{1}{2}(16 + 17)

Q_1 = \frac{1}{2}(33)

Q_1 = 16.5

Q_1 = 16.25

Calculate Q_3

Q_3 = \frac{3}{4}(n + 1)th

Q_3 = \frac{3}{4}(20 + 1)th

Q_3 = \frac{3}{4}(21)th

Remove bracket

Q_3 = 15.75th

This means that:

Q_3 is the mean of 15th and 16th item

From the data:

15th \to 24

16th \to 26

So:

Q_3 = \frac{1}{2}(24 + 26)

Q_3 = \frac{1}{2}(50)

Q_3 = 25

Recall that:

IQR = Q_3 - Q_1

IQR = 25 -16.5

IQR = 8.5
