12. (ST5) The weight of a bag of chips isapproximately normally distributed with amean of 10.72 oz. and a standard deviationof 0

kenny6666 [7]

μ = mean = 10.72 oz

σ =standard deviation = 0.14

x = 10.5

First, find the z-score:

z = x - μ / σ

z = (10.5 - 10.72) / 0.14 = -1.57143

Then find the value on the z-score table:

P (x < 10.5) = 0.058042

If the perimeter of the following figure is 58 meters find x.

Marianna [84]

Answer:

x = 10

Step-by-step explanation:

Sum the 3 sides and equate to 58

6x + 10 + x + 3 - 2x - 5 = 58 , that is

5x + 8 = 58 ( subtract 8 from both sides )

5x = 50 ( divide both sides by 5 )

x = 10

The change from x = 0 to x = 1 is -3

The change from x = 1 to x = 2 is -5

The average of -3 and -5 is $\frac{-3-5}{2} = \frac{-8}{2} = -4$

The answer is D. -4
