Well to get that answer is simple, just divide 121 and 35.

121 divided by 35 = 3.4571428571

You would have to divide 121÷35, you will get a decimal.
the decimal is 3.457142857, that's the answer, you could also round it to 3.46

Greenfield village is spread across 240 acres of land. Only 37% of the land is used for the exhibits, while the rest of the land

Sergeeva-Olga [200]

Answer:

The land which are used for exhibits are 89 acres (approximately).

Step-by-step explanation:

Given:

Village is spread across 240 acres of land. 37% of land is used for the exhibits.

Now, we have to find acres of land which are used for exhibits.

So, here it is given that land used for exhibits is 37%, and we have to calculate the quantity from the percentage given:

According to question:

37% of 240 acres of land.

$\frac{37}{100}\times 240$

$0.37\times 240$

$88.80$

So, the land used for exhibits are 88.80 acres.

Therefore, the land which are used for exhibits are 89 acres (approximately).

Hi! I'm having trouble with my algebra homework. The second question (b) confused me, I don't understand what they are asking or

Yakvenalex [24]

Don't forget that you can also pull out an x besides the 10. The expression should look like this.

A(x) = 10x(x - 5)

The GCF is 10x

The area of the Bedroom = 10x ( x - 5)

If the length = 5x then the width is

A/L = 10x (x - 5)/(5x)= 2*(x - 5)

Now they are changing the Length to the GCF. We determined in A that the GCF = 10x

This time A/L = 10x(x - 5)/10x = (x - 5)

So the width = x - 5

5t-14=-14 solve the equation for t

ikadub [295]

Hi there!

Before we begin, let's rewrite your equation. :)

$5t - 14 = -14$

Step 1) Add 14 to both sides.

$5t - 14 + 14 = -14 + 14 5t = 0$

Step 2) Divide both sides by 5.

$\frac{5t}{5} = \frac{0}{5}$

$t = 0$

Final Answer -

$t = 0$

Hope this helps!

Message me if you need anymore help! :D

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the

Rasek [7]

Answer:

$\mu_{p} = p = 0.06$

And the standard error is given by:

$SE_{p} = \sqrt{\frac{\hat p(1-\hat p)}{n}}$

And replacing we got:

$SE_[p]= \sqrt{\frac{0.06*(1-0.06)}{373}}= 0.0123$

And we want to find this probability:

$P(\hat p < 0.03)$

We can calculate the z score for this case and we got:

$z = \frac{\hat p -\mu_p}{\Se_p} = \frac{0.03-0.06}{0.0123}= -2.440$

And using the normal distribution table or excel we got:

$P(\hat p < 0.03)= P(Z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

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

Solution to the problem

For this case we can find the mean and standard error for the sample proportion with these formulas:

$\mu_{p} = p = 0.06$

And the standard error is given by:

$SE_{p} = \sqrt{\frac{\hat p(1-\hat p)}{n}}$

And replacing we got:

$SE_[p]= \sqrt{\frac{0.06*(1-0.06)}{373}}= 0.0123$

And we want to find this probability:

$P(\hat p < 0.03)$

We can calculate the z score for this case and we got:

$z = \frac{\hat p -\mu_p}{\SE_p} = \frac{0.03-0.06}{0.0123}= -2.440$

And using the normal distribution table or excel we got:

$P(\hat p < 0.03)= P(Z$
