Answer:

I believe the answer is a imaginary number... I only know the fist one I'm sorry..

Step-by-step explanation:

I think this because a rational number is a number that is real. A Whole number is one without decimals. A natural number is something that is also real. I really hope this is helpful.

A school club needs 300 feet of rope for a project. They have the amounts of rope listed below.
Minchanka [31]

Answer:

43.25 feet.  

Step-by-step explanation:

We have been given that school club needs 300 feet of rope for a project.

First of we will change given lengths of ropes in feet.

\text{2 pieces of 16 yards}=2\times16\text{ yards}=32\text{ yards}

1 yard =3 feet

32 yards= 3*32 feet = 96 feet.

12.5 yards = 3*12.5 feet = 37.5 feet.

Let us find the amount of rope school already have by adding all the given amounts.  

\text{Total amount of rope that school club already have}=96+37.5+123.25

\text{Total amount of rope that school club already have}=256.75

Now let us subtract 256.75 feet from 300 feet to find the amount of rope that school club needs to complete the project.

\text{Amount of rope school club needs to complete the project}=300-256.75

\text{Amount of rope school club needs to complete the project}=43.25

Therefore, the school club needs 43.25 feet of additional rope to complete their project.

Subtract the rational expression and simplify<br> x+2/2x-6 - x+3/5x-15
SashulF [63]

Answer: -3x² - 2x -57

This is how this would look: \frac{x+2}{2x-6} - \frac{x+3}{5x-15}

First I brought the denominator to the top for both expressions.

so I was left with: 2x-6(x+2) - 5x-15(x+3)

I distributed, combined like terms, and simplified.

<em><u> -3x² - 2x -57</u></em> was my answer

Step-by-step explanation:

Trust Milky. Milky smart.

Can someone please solve 10n - 3 = 7n + 21
Ira Lisetskai [31]
10 n-3 = 7n+21

Add 3 to both sides :

10n-3+3=7n+21+3

10n=7n+24

Subtract  7 n from both sides:

10n-7n=7n+24-7n

3n=24

Divide both sides by 3 :

\frac{3n}{3} = \frac{24}{3}

n = 8

hope this helps!

Based on historical data, your manager believes that 26% of the company's orders come from first-time customers. A random sample
scoundrel [369]

Answer:

\hat p \sim N( p, \sqrt{\frac{p (1-p)}{n}})

And we can use the z score formula given by:

z = \frac{\hat p -\mu_p}{\sigma_p}

And if we find the parameters we got:

\mu_p = 0.26

\sigma_p = \sqrt{\frac{0.26(1-0.26)}{158}} = 0.0349

And we can find the z score for the value of 0.4 and we got:

z = \frac{0.4-0.26}{0.0349}= 4.0119

And we can find this probability:

P(z>4.0119) = 1-P(z

And if we use the normal standard table or excel we got:

P(z>4.0119) = 1-P(z

Step-by-step explanation:

For this case we have the following info given:

p = 0.26 represent the proportion of the company's orders come from first-time customers

n=158 represent the sample size

And we want to find the following probability:

p(\hat p >0.4)

And we can use the normal approximation since we have the following two conditions:

1) np = 158*0.26 = 41.08>10

2) n(1-p) = 158*(1-0.26) = 116.92>10

And for this case the distribution for the sample proportion is given by:

\hat p \sim N( p, \sqrt{\frac{p (1-p)}{n}})

And we can use the z score formula given by:

z = \frac{\hat p -\mu_p}{\sigma_p}

And if we find the parameters we got:

\mu_p = 0.26

\sigma_p = \sqrt{\frac{0.26(1-0.26)}{158}} = 0.0349

And we can find the z score for the value of 0.4 and we got:

z = \frac{0.4-0.26}{0.0349}= 4.0119

And we can find this probability:

P(z>4.0119) = 1-P(z

And if we use the normal standard table or excel we got:

P(z>4.0119) = 1-P(z
