Answer:

8:1

Step-by-step explanation:

Volume of a cube = Length of edge³

So the equation for the small cube is,

V=L³

If the edge of the bigger cube is twice as long as the smaller cubes edge, then the equation for the bigger cube is:

V = (2L)³

= (2³)L³

= (8)L³

Combining these two in ratio form:

(8)L³ : (1)L³

You can remove the L³ from each side because they are equal

So the answer is 8:1

The simple interest due on a 6-month loan of $2,500 is $125. What is the monthly payment on the loan?

Elina [12.6K]

A person borrows $2500 and they must pay this amount back, plus the $125 in simple interest. In total, they must pay back 2500+125 = 2625 dollars.

Divide this amount over 6 months
2625/6 = 437.50

The monthly payment is $437.50, so the answer is choice B

Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund

ser-zykov [4K]

Testing the hypothesis, it is found that since the p-value of the test is 0.0042 < 0.01, it can be concluded that the proportion of subjects who respond in favor is different of 0.5.

At the null hypothesis, it is tested if the proportion is of 0.5, that is:

$H_0: p = 0.5$

At the alternative hypothesis, it is tested if the proportion is different of 0.5, that is:

$H_1: p \neq 0.5$

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1 - p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.
p is the value tested at the null hypothesis.
n is the sample size.

In this problem, the parameters are given by:

$p = 0.5, n = 483 + 398 = 881, \overline{p} = \frac{483}{881} = 0.5482$

The value of the test statistic is:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1 - p)}{n}}}$

$z = \frac{0.5482 - 0.5}{\sqrt{\frac{0.5(0.5)}{881}}}$

$z = 2.86$

Since we have a two-tailed test(test if the proportion is different of a value), the p-value of the test is P(|z| > 2.86), which is 2 multiplied by the p-value of z = -2.86.

Looking at the z-table, z = -2.86 has a p-value of 0.0021.

2(0.0021) = 0.0042

Since the p-value of the test is 0.0042 < 0.01, it can be concluded that the proportion of subjects who respond in favor is different of 0.5.
