Answer: 59.91%.
Step-by-step explanation:
- We know that the fraction of the variability in data values accounted by a model is given by
, where r is the coefficient of correlation.
We are given , that the correlation between a car’s engine size and its fuel economy (in mpg) is r = - 0.774.
Then, the fraction of the variability in fuel economy is accounted for by the engine size would be 
[Multiply 100 to convert a decimal into percent]
Hence, the fraction of the variability in fuel economy is accounted for by the engine size is 59.91%.
None of the options are correct.
We have 1 m = 100cm
⇒ 72 m = 7200 cm
⇒ 7200 / 1.5= 4800 cm = 48 m
Answer:
1. We have been given that a∥b , and c is neither parallel to a nor b.
Let us see which of our given options are correct.
A. m∠7 can not be equal to m∠11 as line c is not parallel to line a.
B. m∠5 can not be equal to m∠12 as line c is not parallel to line b.
C. By alternate interior angles m∠4=m∠5 as ∠4 is inside line a and ∠5 is inside line b. Both angles are on the opposite sides of transversal.
D. Since we know that corresponding angles are congruent. We can see that ∠5 corresponds to ∠1, therefore, m∠1=m∠5.
Therefore, Option C and D are correct choices.
2. We have been given that AB∥CD and m∠4=85°. We are asked to find measure of ∠5.
Since we know that same side interior angles are supplementary. In our figure we can see that ∠4 and ∠5 are same side interior angles.
Therefore, measure of ∠5 will be 95 degrees.
Step-by-step explanation:
1. is m∠4=m∠5 by the alternate interior angle theorem.
2. Angles 4 & 3 are supplementary angles or linear pair and so they have to equal 180 and 180 - 85= 95 3 & 5 are corresponding angles so 95 should be your answer.

Answer:
4pi/15=θ - i think
Step-by-step explanation:
S = r*θ
r=9
s=12pi/5
12pi/5=9*θ
12pi/45=θ
4pi/15=θ
