Factor the polynomial completely 20x -220x squared + 600x

1 answer:

7 0

I first would rearrange the problem

-220x^2 + 20x + 600x

Simplify

-220x^2 + 620x

Find the GCF of the two values

20x(11x + 13)

Hope this helps!

Answer:

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Step-by-step explanation:

Margin of error

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation and n is the size of the sample.

Standard deviation of 1.3

This means that $\sigma = 1.3$

She surveys 124 families

This means that $n = 124$

Margin of error and meaning:

$M = z\frac{\sigma}{\sqrt{n}}$

$M = 2.58\frac{1.3}{\sqrt{124}}$

$M = 0.3012$

The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Lady bird [3.3K]

City code says you need to have a total of at least 54 toilet stalls, but each bathroom can only have 6 stalls.

So, Let the number of bathrooms to be built be = x

Number of toilet stalls needed = 54

Number of stalls each bathroom can have = 6

So, the number of bathrooms to be built are =

$6(x)=54$

$x=\frac{54}{6}$

$x=9$

Hence, one must build 9 bathrooms with 6 stalls each.
