A soccer ball manufacturer wants to estimate the mean circumference of mini-soccer balls within 0.12 inch. Assume that the population of circumferences is normally distributed with a population standard deviation of 0.78 inch. How many balls must the manufacturer sample in order to construct a 90% confidence interval for the population mean

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

yes   because as the functions are graphed they eventually will intersect unless otherwise
