Hi there

This is how you read the question: What is the cube root of 64.
To answer this question ask yourself what number multiplied by itself three times gives you the answer 64?
1*1*1=1
2*2*2=8
3*3*3=27
4*4*4=64
YAY! that means the answer is 4.

Hope this helps.
And you give me the brainliest answer.
Thanks

Answer:

$2\frac{1}{3}\: ft$

Step-By-Step Explanation:

$Height\: of \:sail = 1\frac{1}{6}\: ft = \frac{7}{6}\: ft\\Base\: of \:sail = 4\: ft \\Area\: of \:sail =\frac{1}{2} \times base \times height\\=\frac{1}{2} \times \frac{7}{6} \times 4\\= \frac{7}{6} \times 2\\=\frac{7}{3}\\=2\frac{1}{3}\: ft$

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for

Alona [7]

The equation is L = 34 – 0.5d for the water level, L, after d days

<h3><u>Solution: </u></h3>

Given that , Suppose that the water level of a river is 34 feet

And that it is receding at a rate of 0.5 foot per day.

We have to write an equation for the water level, L, after d days

The equation can be framed for water level after d days which is found by calculating difference between initial level and receding level of water per day

Now , we know that,

<em>water level after d days = initial level – receded level of water. </em>

L = 34 feet – number of days spent x rate of receding level per day.

L = 34 feet – d days x 0.5 foot

L = 34 – 0.5d

Hence, the equation is L = 34 – 0.5d

Netflix is considering a new romcom (romantic comedy) series. Before making a final decision, the producers design an experiment

Airida [17]

A) the value of the population proportion of people who would watch the new series is 5 out of 8 viewers, and B) a 99% confidence interval for the population proportion of people who would watch the new series indicates that between 61.87% and 63.13% of viewers will watch the new series.

<h3><u>Proportions</u></h3>

Given that Netflix is considering a new romcom (romantic comedy) series, and a random sample of 1,000 viewers was selected and 625 viewers indicated they would watch the new series, for A) estimate the value of the population proportion of people who would watch the new series, and B) develop a 99% confidence interval for the population proportion of people who would watch the new series, the following calculations must be made:

625 = 1

1000 = X

1000 / 625 = X

1.6 = X

10 out of 16, or 5 out of 8.

62.5 x 0.99 = 61.875

62.5 x 1.01 = 63.125

Therefore, A) the value of the population proportion of people who would watch the new series is 5 out of 8 viewers, and B) a 99% confidence interval for the population proportion of people who would watch the new series indicates that between 61.87% and 63.13% of viewers will watch the new series.
