The reciprocal of 2/3 is 3/2. If the reciprocal of 4x/5 is 1/20, what is x?

Black_prince [1.1K]

Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation $\frac{4x}{5}=20$ . From there we can solve for x.

Firstly, multiply both sides by 5: $4x=100$

Next, divide both sides by 4 and your answer will be $x=25$

Answer:

The guaranteed mileage should be 31800 miles.

Step-by-step explanation:

Consider the provided information.

It is given that the normally distributed with a mean of 40,000 miles and a standard deviation of 4,000 miles. Also the company desires that no more than 2 percent of the tires will fail to meet the guaranteed mileage.

That means the p < 0.02

Now with the help of the table the respective Z-score value of p < 0.02 is -2.05

From the provided information mean and standard deviation is given as $\mu = 40,000\ \text{and}\ \sigma = 4000$
