A rectangle is 12m longer than it is wide. Its perimeter is 68m. Write and equation and show steps to find its length and width.

Galina-37 [17]

Answer:

length: 23 m; width: 11 m.

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:

l + w = 34

l - w = 12

Adding these together gives you ...

2l = 46

l = 23 . . . . . . divide by 2

Then the width is

w = 23 -12 = 11

The length and width are 23 m and 11 m, respectively.

Home sizes in Anytown, USA have a mean of 2400 square feet and a standard deviation of 450 square feet. What is the probability

lesya [120]

Answer:

0.00084

Step-by-step explanation:

We are given that

Mean, $\mu=2400$ square feet

Standard deviation, $\sigma=450$ square feet

n=50

We have to find the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet.

$P(x$

Using the formula

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$P(x$

$P(X$

Hence, the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet=0.00084
