Answer:

x = 2

Step-by-step explanation:

-3x - 6 = 8x + 16

8x - 3x = 16 - 6 (subtract like terms)

5x = 10 (divide by 5)

x = 2

F(x) = x^2 - 3x+ 5 g(x) = 2x^2 - 4x - 11 what is h(x) = f(x) + g(x)
iogann1982 [59]

Hey there! :)

Answer:

h(x) = 3x² - 7x - 6

Step-by-step explanation:

Calculate h(x) by adding the two polynomials:

h(x) = f(x) + g(x):

h(x) = x² - 3x + 5 + 2x² - 4x - 11

Combine like terms:

h(x) = 3x² - 7x - 6

Cook-Easy blender has a mean time before failure of 41 months with a standard deviation of 4 months, and the failure times are n
Naddika [18.5K]

Answer:

The warranty period should be of 35 months.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Cook-Easy blender has a mean time before failure of 41 months with a standard deviation of 4 months

This means that \mu = 41, \sigma = 4

What should be the warranty period, in months, so that the manufacturer will not have more than 8% of the blenders returned?

The warranty period should be the 8th percentile, which is X when Z has a p-value of 0.08, so X when Z = -1.405.

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

-1.405 = \frac{X - 41}{4}

X - 41 = -1.405*4

X = 35.4

Rounding to the nearest integer, 35.

The warranty period should be of 35 months.
