Could someone assist me with this?

Answer:

Step-by-step explanation:

1.

Formula for Area of a parallelogram: A = bh

So multiply the base (25cm) by the height (16cm) to get 400cm^2.

2.

Volume formula l x w x h

Multiply the length of the pool (20ft) by the width (15ft) by the height (6ft) to get 1,800ft^2

3.

Formula for Area of a trapezoid A= a+b/2 * h

Where a is (12.6in), b is (15in), and h is (3.4in) just plug in the numbers into the formula to get 46.92in^2

4.

Same thing as number one, use the Area of a parallelogram formula A = bh

A certain brand of automobile tire has a mean life span of 35,000 miles, with a standard deviation of 2250 miles. Assume the lif

yawa3891 [41]

Answer:

Step-by-step explanation:

From the information given:

mean life span of a brand of automobile = 35,000

standard deviation of a brand of automobile = 2250 miles.

the z-score that corresponds to each life span are as follows.

the standard z- score formula is:

$z = \dfrac{x - \mu}{\sigma}$

For x = 34000

$z = \dfrac{34000 - 35000}{2250}$

$z = \dfrac{-1000}{2250}$

z = −0.4444

For x = 37000

$z = \dfrac{37000 - 35000}{2250}$

$z = \dfrac{2000}{2250}$

z = 0.8889

For x = 3000

$z = \dfrac{30000 - 35000}{2250}$

$z = \dfrac{-5000}{2250}$

z = -2.222

From the above z- score that corresponds to their life span; it is glaring that the tire with the life span 30,000 miles has an unusually short life span.

For x = 30,500

$z = \dfrac{30500 - 35000}{2250}$

$z = \dfrac{-4500}{2250}$

z = -2

P(z) = P(-2)

Using excel function (=NORMDIST -2)

P(z) = 0.022750132

P(z) = 2.28th percentile

For x = 37250

$z = \dfrac{37250 - 35000}{2250}$

$z = \dfrac{2250}{2250}$

z = 1

Using excel function (=NORMDIST 1)

P(z) = 0.841344746

P(z) = 84.14th percentile

For x = 35000

$z = \dfrac{35000- 35000}{2250}$

$z = \dfrac{0}{2250}$

z = 0

Using excel function (=NORMDIST 0)

P(z) = 0.5

P(z) = 50th percentile
