So 2.5^2= 1.5^2 +b^2
6.25= 2.25 +b^2
Subtract 2.25 on each side
4= b^2
Take the square root of each side
X=2

Hope it helps

Find the length of the line segment formed by the points (2, 3) and (2, 5)

SCORPION-xisa [38]

Answer:

2 units

Step-by-step explanation:

Given data

The points are (2, 3) and (2, 5)

x1= 2

y1= 3

x2= 2

y2= 5

substitute into the distance between two points formula

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-2)²+(5-3)²)

d=√(2)²)

d=√4

d= 2 units

Hence the length is 2 units

Consider the following dot plots.

motikmotik

The correct answer is:

A) The medians are both between 10 and 14 emails.

Explanation:

The mode is the easiest measure to find of a data set.
The mode of a data set is the data value that appears the most often. In plot A, there are 3 dots at 10 and 3 dots at 15; this means the modes are 10 and 15.

In plot B, there are 3 dots at 5 and 3 dots at 15; this means the modes are 5 and 15.

They do not have the same modes.

The median of a data set is the middle value. There are 10 dots in each dot plot; this means the medians will each be between two data points.

For plot A, we can see that the middle value is between 10 and 15.
For plot B, we can see that the middle value is between 10 and 15.

This means that choice A is correct, the medians of both are between 10 and 14.

During a period of 80 minutes, a music station played 8 minutes of commercials. What is the ratio of music they played to commer

igomit [66]

Answer:

Step-by-step explanation:

80 minutes.......8 minutes played commercials....that means (80 - 8) = 72 minutes played music

so the ratio of music to commercials is : 72/8 which reduces to 9/1...so the ratio is 9:1 <=== ur answer

** pay attention to the wording, because if it would have asked for the ratio of commercials to music, it would have been 8/72....ratio would be 1:9

Someone help, I suck at math

attashe74 [19]

option A.55°

Answer:

Solution given:

<x+<y=<z

exterior angle of a triangle is equal to the sum of two opposite interior angle

4n-18+n+8=133-6n

5n+6n=133+10

11n=143

n=143/11

n=13

exterior angle =133-6*13=55°

option A.55°
