Answer:

A

Step-by-step explanation:

z = y                                  Both are opposite equal sides

z = 70                                From the first statement.

y = 70                                Given

x = 180 - z - y                    A triangle has 180 degrees

x = 180 - 70 - 70

x = 40

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 108.7-cm and a standard dev
Luden [163]

Let x be the lengths of the steel rods and X ~ N (108.7, 0.6)

To get the probability of less than 109.1 cm, the solution is computed by:


z (109.1) = (X-mean)/standard dev

= 109.1 – 108/ 0.6

= 1.1/0.6

=1.83333, look this up in the z table.


P(x < 109.1) = P(z < 1.8333) = 0.97 or 97%
