Answer:
Graph B
Step-by-step explanation:
we know that
The graph that represent the situation
As x increases, y increases
Is the graph B or the graph C
but
Graph B represent a moderate coefficient of correlation r (-0.5 to -0.3 or 0.3 to 0.5)
Graph C represent a strong coefficient of correlation r (-1.0 to -0.5 or 1.0 to 0.5)
In this problem we have r=0.42
so
The coefficient of correlation is Moderate
therefore
The answer is the Graph B
Answer: 9c²
<u>Step-by-step explanation:</u>
To find the Greatest Common Factor of 207c³ and 108c², first factor them down to their primes and see what they have in common.
207c³ 108c²
∧ ∧ ∧ ∧
9·23 c·c·c 9·12 c·c
∧ ∧ ∧
3·3 3·3 3·4
∧
2·2
207c³: 3·3·23 c·c·c
108c²: 2·2·3·3·3·4 c·c
GCF = 3·3 c·c
= 9c²
Answer:
<u>The correct answer is D. 114</u>
Step-by-step explanation:
There are 252 students of twelfth grade at Vista View High School.
99 walked to school
11 went by bicycle
28 used the school bus
To find the amount of twelfth graders that rode in a car, we do this calculation:
Amount of twelfth graders that rode in a car = Total of twelfth graders - those who walked - those who went by bicycle - those who used the bus
Replacing with the real values, we have:
Amount of twelfth graders that rode in a car = 252 - 99 - 11 - 28 = 252 - 138 = 114
<u>The correct answer is D. 114</u>
Answer:

linear/proportional
Answer:
3
Step-by-step explanation:
- 3 |2x -3| -5=4
- 3 |2x -3| =4+5
- 2x-3=9÷3
- 2x=3+3
- x=6÷2
- x=3
