I just took the quiz, the answer is A: Critical values=0.312; there is sufficient evidence to support a claim of a linear correlation between before-and-after weights.
Answer:
a.) $3.20
b.) $102.40
$3,276.80
Step-by-step explanation:
0.2 times 2 five times is 3.2
0.2 times 2 ten times is 102.4
0.2 times 2 fifteen times is 3,276.8
From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is
x= 3y
And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get
or
The store paid $17.00
Solution: $24.00 (selling price) - $7.00 (difference of what the store paid) = $17.00
