Mathematics
1 answer:
Harman [31]3 years ago
6 0

Answer:B. Her mean, median and mode are equal.

Step-by-step explanation:

Mean = (sum of the outcomes)/(total number of outcomes)

Total number of rounds played is 7

The scores for the 7 rounds played are - 6, - 4, - 1 , +3 , - 2, -1, +4

Sum of the scores = - 6 - 4 - 1 + 3 - 2 -1 + 4 = -7

Mean = - 7/7 = - 1

The mode is the most occurring score. Looking at the scores, - 1 occurred twice, so the mode is - 1

The median is the middle score. We would determine it by rearranging the scores in increasing or decreasing order. It becomes

- 6, - 4, - 2, -1, -1, +3, +4

The median is -1

The true statement is

B. Her mean, median and mode are equal.

What is an equation of the line that passes through the points (4,-2) and (-1,3)
Paraphin [41]

Answer:

<h3>The slope is -1.</h3>

Step-by-step explanation:

To find an equation of the line that passes through the points, you have to use the slope formula.

Slope:

\Rightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

y2=3

y1=(-2)

x2=(-1)

x1=4

Solve.

3--2/-1-4=5/-5=-1

The slope is -1.

I will give BRAINLIEST! HELP PLEASE.!!!<br><br> 2. Find each measure. <br> m&lt;1 m&lt;2 m&lt;3

<h3>Answer: Choice B</h3>

Angle 1 = 147 degrees

Angle 2 = 80 degrees

Angle 3 = 148 degrees

======================================================

Work Shown:

(angle 1) + 33 = 180

angle 1 = 180-33

angle 1 = 147 degrees

---------------

Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees

The angle exterior to this 100 degree angle is angle 2

angle 2 = 180-100 = 80

We have enough info to conclude the answer must be choice B.

---------------

Let's keep going to find angle 3

The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right

This triangle on the right has interior angles 100 and 48

The missing interior angle is 180-100-48 = 32

The angle supplementary to this is 180-32 = 148, which is angle 3.
