The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 257.8 and a standard deviation of 60.6. (all units are 1000 cells/mul.) using the empirical rule, find each approximate percentage below. a. what is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 197.2 and 318.4? b. what is the approximate percentage of women with platelet counts between 136.6 and 379.0?

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
