Answer:
See below
Step-by-step explanation:
Lets assume weight is input and time is output
The function based on the input and output values is close to linear and it is decreasing (graph is attached)
<u>Answers are</u>
- a) correlation is negative as time decreases with increase in weight.
- b) Numeric value is obtained -0.99 by using the formula attached as picture. It is 'very strong negative relationship'
- c) Yes. Because weigh increase causes time to decrease
Answer:
$960
Step-by-step explanation:
take the total salary to be 100%, since the taxes are 20% subtract 20% from 100% to get 80% which will represent the left over after the taxes have been taken so say if 100%=$1200 what about 80% 80times 1200 then divide by 100.
Answer:
∠ DBE = 25.5°
Step-by-step explanation:
Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then
∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°
Answer:
17.5 + 15.5
Step-by-step explanation:
17+ 15 = 32
.5 + .5 = 1
32 + 1 = 33
Answer:
(9-10x)(9+10x) (I think this is the answer but I'm not one hundred percent sure)
Step-by-step explanation:
First, you can recognize that both numbers (-100x^2 and 81) are a difference of squares, in which means that they both can be square routed. Then, plug in the square routes of the numbers into (9-10x)(9+10x). 9 is the square route of 81 and 10 is the square route of 100. Make sure that when you put the numbers in the parenthesis that there is one negative and positive number since a negative multiplied by a positive makes a negative, hence making 100 negative. I hope that helped.
