Answer:

13

Step-by-step explanation:

f (x) = x/2 + 8

If x = 10, replace the x with 10.

f (x) = 10 / 2 + 8

f (x) = 5 + 8

f (x) = 13

Assume that the probability of a defective computer component is 0.02. Components arerandomly selected. Find the probability tha
solmaris [256]

Answer:

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Step-by-step explanation:

Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.

First six not defective, each with 0.98 probability.

7th defective, with 0.02 probability. So

p = (0.98)^6*0.02 = 0.0177

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.

Find the expected number and variance of the number of components tested before a defective component is found.

Inverse binomial distribution, with p = 0.02

Expected number before 1 defective(n = 1). So

E = \frac{n}{p} = \frac{1}{0.02} = 50

Variance is:

V = \frac{np}{(1-p)^2} = \frac{0.02}{(1-0.02)^2} = 0.0208

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
GREYUIT [131]

Answer:

  • Decay
  • Decrease rate is 8%

Step-by-step explanation:

<u>Given function:</u>

  • y = 490(0.92)^x

The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.

<u>The rate of decrease is </u>

  • 0.92 times

<u>Percent decrease is </u>

  • (1 - 0.92)*100% = 8%
