It is given that R=2q-5 and Q=3p+2. Find the numerical value of R when p=3

saveliy_v [14]

Answer:

R = 17

Step-by-step explanation:

R = 2q - 5

Q = 3p + 2

Find the numerical value of R when p = 3

R = 2q - 5

R = 2(3p + 2) - 5

R = 6p + 4 - 5

R = 6p - 1

When p = 3

R = 6(3) - 1

R = 18 - 1

R = 17

The operation manager at a tire manufacturing company believes that the mean mileage of a tire is 48,637 miles, with a variance

Brut [27]

Answer:

$P(x < -778) = 0$

Step-by-step explanation:

Given

$\bar x = 48673$

$\sigma^2 = 11282880$

$n = 143$

Required

$P(x$

First, we calculate the z score

$z = \frac{x}{\sqrt{\sigma^2}/n}$

So, we have:

$z = \frac{-778}{\sqrt{11282880}/143}$

$z = \frac{-778}{3359.0/143}$

$z = \frac{-778}{23.49}$

$z = -33.12$

So:

$P(x < -778) = P(z < -33.12)$

From z score probability, we have:

$P(x < -778) = 0$
