Step-by-step explanation:

3/4 x 2 2/3 =

Convert 2 2/3 into a improper fraction!

Step 1. Multiply denominator by whole number.

2 2/3 = 3 • 2

Step 2. Add the numerator to the expression!

2 2/3 = 3 • 2 + 2

Step 3. Add the denominator after the expression.

2 2/3 = 3 • 2 + 2 / 3

Step 4. Solve

2 2/3 = 6 + 2 / 3

2 2/3 = 8 / 3
______________________________
Now instead of using 2 2/3 we are going to use 8/3!

Then we can start multiplying the two fractions (3/4 x 8/3)

Step 1. Multiply the numerator by numerator over denominator by denominator!

3/4 x 8/3 = 3 • 8/4 • 3

Step 2. Solve

3/4 x 8/3 = 24/12

Simplify 24/12

24/12 = 2

88-55+ 5x-7=180 Find the value of x

marshall27 [118]

Answer:

x = 30.8

Step-by-step explanation:

88 - 55 + 5x -7 = 180

33 + 5x -7 = 180

5x -7 = 180 - 33

5x - 7 = 147

5x = 147 +7

5x = 154

x = 154/5

x = 30.8

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000

Elis [28]

Answer:

84.13% probability a particular tire of this brand will last longer than 57,100 miles

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

$\mu = 60000, \sigma = 2900$
