The diameters of ball bearings are distributed normally. The mean diameter is 7373 millimeters and the variance is 44. Find the probability that the diameter of a selected bearing is less than 7676 millimeters. Round your answer to four decimal places.

0.9332

Step-by-step explanation:

We are given that

Mean diameter,

Variance,

We have to find the probability that the diameter of a selected bearing is less than 76.

Standard deviation,

Where

Hence, the probability that the diameter of a selected bearing is less than 76=0.9332

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
