Y=5-2x
x^2 + (5-2x)^2 = 25
x^2 + 25-20x+4x^2 = 25
x^2 +4x^2-20x+25=25
5x^2 -20x=0
x=0 and y=5
Answer:
d. Taking larger samples more frequently
Step-by-step explanation:
The alternative that will increase the probability of detecting a shift in the process average is option D.
d. Taking larger samples more frequently
.
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 miles
Answer:
agree with both because 1 dollar = 4 muffins so 2 x 4 = 8 muffins and 4x4 = 16 muffins
