Items produced by a manufacturing process are supposed to weigh 90 grams. The manufacturing procon such, however, that there is variability in the items produced and they do not all weigh exactly 90
distribution of weights can be approximated by a Normal distribution with mean 90 grams and a standard
deviation of 1 gram. About what percentage of the items will either
weigh less than 87 grams or more than
93 grams?

the answer for your question is

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
