You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14

The average life of a certain type of small motor is 10 years with a standard deviation of 2 years. The manufacturer replaces fr
Ivenika [448]

Answer:

She should offer a guarantee of 6.24 years.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 10, \sigma = 2

If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?

This is the value of X when Z has a pvalue of 0.03. So it is X when Z = -1.88. So

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

-1.88 = \frac{X - 10}{2}

X - 10 = -1.88*2

X = 6.24

She should offer a guarantee of 6.24 years.

In mathematics, sometimes the word 'of' means 'multiply'.

\frac{2}{3} * \frac{3}{4} = \frac{6}{12}

Simplify.

\frac{6}{12} = \frac{1}{2}

So, 1/2 is the answer.
