(CO 4) Determine the minimum sample size required when you want to be 75% confident that
the sample mean is within twenty units of the
population mean. Assume a standard deviation of
327.8 in a normally distributed population

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
