Engineers must consider the breadths of male heads when designing motorcylces helmets. men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inches. the safeguard helmet company plans an initial production run of 100 helmets. find the probability that 100 randomly selected men have mean head breadth less than 6.2 inches

d.192

step-by-step explanation:

12*16=192

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
