The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.05 inches and a standard dev
Viefleur [7K]

Answer:

6.68% or 0.0668

Step-by-step explanation:

Mean sheet length (μ) = 30.05 inches

Standard deviation (σ) = 0.2 inches

In a normal distribution, for any length X, the z-score is determined by the following expression:

z=\frac{X-\mu}{\sigma}

For X = 29.75, the z-score is:

z=\frac{29.75-30.05}{0.2}\\z=-1.5

A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution.

Therefore, the probability that a sheet selected at random will be less than 29.75 inches long is 6.68%.

87th term of 12,0,-12
Elan Coil [88]

Answer:

a_{87} = -1020

Step-by-step explanation:

Given:

The given AP is.

12,0,-12,......

n=87

The first term of an AP a=12

Common difference d=0-12=-12

We use the the formula for nth term of an AP.

a_{n} = a+(n-1)d

for 87th term

a_{87} = 12+(87-1)(-12)

a_{87} = 12+(86)(-12)

a_{87} = 12+(-1032)

a_{87} = 12-1032

a_{87} = -1020

Therefore, The 87th term of given series is -1020.
