Battery packs in electric go-carts need to last a fairly long time. The run-times (time until it needs to be recharged) of the b
pav-90 [236]

Answer:

The minimum level for which the battery pack will be classified as highly sought-after class is 2.42 hours

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 = 2, \sigma = 0.33

What is the minimum level for which the battery pack will be classified as highly sought-after class

At least the 100-10 = 90th percentile, which is the value of X when Z has a pvalue of 0.9. So it is X when Z = 1.28.

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

1.28 = \frac{X - 2}{0.33}

X - 2 = 0.33*1.28

X = 2.42

The minimum level for which the battery pack will be classified as highly sought-after class is 2.42 hours

The measures of two sides of a triangle are 7.3 centimeters and 2.94 centimeters. The triangle's perimeter is 14.8 centimeters.
evablogger [386]
The perimeter is the sum of all lengths of the side of a polygon. For a triangle it is expressed as:

P = a + b + c

We let a = 7.3, b = 2.94 and c=x

Therefore, the perimeter of the given triangle is:

14.8 = 7.3 + 2.94 + x

From the options given, the correct answer is the last option. The expression, <span>x - 14.8 = 2.94 + 7.3, will give an erroneous value of the third side. It will be more than the perimeter given.</span>
