A tire company finds that the lifespan for one brand of its tires is normally distributed with a mean of 47,500 miles and a stan

Illusion [34]

Answer:

42580 miles

Step-by-step explanation:

Mean = $\mu = 47500$

$\sigma = 3000$

The manufacturer does not want to replace more than 5% of the tires

$P(X\leq x)=5\%$

$P(\frac{x-\mu}{\sigma}\leq \frac{x-47500}{3000})=0.05$

By using normal table values :

$\frac{x-47500}{3000}=-1.64$

$x=(-1.64 \times 3000)+47500$

$x=42580$

Hence the approximate number of miles for the warranty is 42580 miles

A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes: 3 4 5 2 7 1 3 7 2 6 2 1 7 3

Greeley [361]

The prime numbers on the dice are 1,2,3,5 and 7 , the theoretical probability is
$\frac{5}{8}$ , which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is $\frac{3}{4}$ , which is 75%, the difference between the experimental probability and the <span>theoretical probability is 12.5%.</span>
