Gemiola [76]

Answer:

50 years

Step-by-step explanation:

use the simple interest formula :

PRT/100

P is the principle (5000)

R is the rate of interest (4)

T is the time taken (x- unknown)

the amount at the end is double the amount invested = 5000*2 = 10000

(5000*4 * x )/100 = 10000

20000x/100=10000

20000x = 100*10000

20000x = 1 000 000

x= 1 000 000/ 20 000

x = 50

it will take<u> 50 years </u>

A study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 Chevrolet Cavalier shows that the mean

Nana76 [90]

Answer: 0.0026

Step-by-step explanation:

Given: Mean : $\mu=8.4\text{ hours}$

Standard Deviation : $\sigma = 1.8\text{ hours}$

Sample size : $n=40$

Formula to calculate z-score :-

$z=\dfrac{X-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For X=7.6 hours.

$z=\dfrac{7.6-8.4}{\dfrac{1.8}{\sqrt{40}}}=-2.81091347571\approx-2.8$

$P(X$

Hence, the probability that their mean rebuild time is less than 7.6 hours = 0.0026
