nick is solving the equation 3x^2 = 20 − 7x with the quadratic formula.

which values could he use for a, b, and c?

a. a = 3, b = -7, c = 20

b. a = 3, b = -20, c = 7

c. a = 3, b = 7, c = -20

d. a = 3, b = 20, c = -7

i think it's either a or d but i'm not 100% sure so i could be wrong

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle.he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field

Ur environment is very sensitive to the amount of ozone in the upper atmosphere. the level of ozone normally found is 4.04.0 parts/million (ppm). a researcher believes that the current ozone level is not at a normal level. the mean of 2525 samples is 4.44.4 ppm with a standard deviation of 0.80.8. assume the population is normally distributed. a level of significance of 0.020.02 will be used. make the decision to reject or fail to reject the null hypothesis. answer tables
