Answer: 35
so in one hour she'd do 2.5 hours
so in 14 she'd do 2.5*14=35
We are given the following relation:
y = 4.302 x – 3.293
To solve for the mean value of y when x = 20, what we have
to do is to find for the value of y at x = 20 and the value of y at x = 0. Then
we get the average of the two values.
when x = 0
y(0) = 4.302 (0) – 3.293
y(0) = - 3.293
when x = 20
y(20) = 4.302 (20) – 3.293
y(20) = 82.747
The mean value would be:
mean y = [y(20) + y(0)] / [20 + 0]
mean y = [82.747 + (-3.293)] / 20
<span>mean y = 3.9727 = 3.97</span>
Answer:
56
Step-by-step explanation:
The ratio is 5 to 2, and we must keep it this way.
For example, if he had 10 regular sodas then the ratio would be 10:4.
If something happens to one side of this ratio, it needs to happen to the other so it remains balanced.
We need to find out how 5 got to 140. To find out, simply divide 140 by 5.
140 divided by 5 = 28
So, 5 was multiplied by 28 to get to 140.
Now, we need to multiply the 2 by 28 as well so it remains balanced.
2 x 28 = 56.
So, there are 56 diet sodas.
