You just divide 3/8= 0.375
The regression line equation is
, the value of the slope is shown as constant 16 and it's a positive constant, hence the correlation between the amount of gas used and degree of the days is a POSITIVE correlation.
Answer:
Step-by-step explanation:
When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.
17 * (2/5)
= (17*2)/5
= 34/5
= 6.8
You can then round this number up --> about 7 cars.
Answer: 18
Step-by-step explanation:
Let x be the number of 2 point baskets made and y be the number of 3 point baskets made
:
1) x + y = 26
:
2) 2x + 3y = 60
:
solve equation 1 for x and substitute in equation 2
:
x = 26 - y
:
2(26 - y) +3y = 60
:
52 -2y +3y = 60
:
y = 8
:
x = 26 - 8 = 18

Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
