Assume that females have pulse rates that normally distributed with a mean of 75.0 beats per minit And the standard deviation of 12.5 beats per minute . Complete parts (a) through (c) below. A - if 1 adultes female is randomly selected find the probability that her pulse rate is less than 78 beats per minute?

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
