To find the area of a square, you multiply the side length by itself. So, multiply 18 feet by 18 feet to get 324 square feet.

Since it is a square, all side lengths will be equal. Thus, we can assume that since the equation to find area is wl or width*length, we can simply multiply 18 by 18.
18*18=324
The area of the painting is 324 inches.
Hope this helps!

A superintendent of a school district conducted a survey to find out the level of job satisfaction among teachers. Out of 53 tea

frez [133]

Answer:

b. 1.15

Step-by-step explanation:

The z statistics is given by:

$Z = \frac{X - p}{s}$

In which X is the found proportion, p is the expected proportion, and s, which is the standard error is $s = \sqrt{\frac{p(1-p)}{n}}$

Out of 53 teachers who replied to the survey, 13 claim they are satisfied with their job.

This means that $X = \frac{13}{53} = 0.2453$

She find that the proportion of satisfied teachers nationally is 18.4%.

This means that $p = 0.184$

Standard error:

p = 0.184, n = 53.

$s = \sqrt{\frac{0.184*0.816}{53}} = 0.0532$

Z-statistic:

$Z = \frac{X - p}{s}$

$Z = \frac{0.2453 - 0.184}{0.0532}$

$Z = 1.15$

The correct answer is:

b. 1.15

il63 [147K]

Answer:

Step-by-step explanation:

Alright, lets get started.

In the morning Cynthia completed the work = $\frac{2}{3}$

During her lunch break, she completed = $\frac{1}{8}$

So, she completed total of her work : $\frac{2}{3}+\frac{1}{8}$

So, we need to add these two fractions.

First making common denominator , so

$\frac{16}{24}+\frac{3}{24}$

So, adding = $\frac{19}{24}$

It means she had finished $\frac{19}{24}$ fraction of het to do list. : Answer

Hope it will help :)
