Set up the proportion.  Then cross multiply and isolate the variable to solve.

\frac{8(trash bags)}{30 (days)} = \frac{x (trash bags)}{180 (days)}

8(180)= 30(x)

\frac{8(180)}{30} = \frac{30x}{30}

8(6) = x

48 = x

Answer: 48 trash bags

kipiarov [429]

Answer:

The p-value of the test is 0.0041 < 0.05, which means that there is sufficient evidence at the 0.05 significance level to conclude that the mean cost has increased.

Step-by-step explanation:

The average undergraduate cost for tuition, fees, and room and board for two-year institutions last year was $13,252. Test if the mean cost has increased.

At the null hypothesis, we test if the mean cost is still the same, that is:

H_0: \mu = 13252

At the alternative hypothesis, we test if the mean cost has increased, that is:

H_1: \mu > 13252

The test statistic is:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

13252 is tested at the null hypothesis:

This means that \mu = 13252

The following year, a random sample of 20 two-year institutions had a mean of $15,560 and a standard deviation of $3500.

This means that n = 20, X = 15560, s = 3500

Value of the test statistic:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{15560 - 13252}{\frac{3500}{\sqrt{20}}}

t = 2.95

P-value of the test and decision:

The p-value of the test is found using a t-score calculator, with a right-tailed test, with 20-1 = 19 degrees of freedom and t = 2.95. Thus, the p-value of the test is 0.0041.

The p-value of the test is 0.0041 < 0.05, which means that there is sufficient evidence at the 0.05 significance level to conclude that the mean cost has increased.

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d? Negative 5 c d c d minus 8 d 5 c d minus 8
Pavel [41]

Question

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?

a) Negative 5 c d

b) c d minus 8 d

c) 5 c d minus 8 d

d) Negative 5 c d minus 8 d

Answer:

a) Negative 5cd or -5cd

Step-by-step explanation:

The question asks:

What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?

This is expressed mathematically as:

-3cd - d(2c - 4) - 4d

= -3cd -2cd + 4d - 4d

= -5cd + 0

= -5cd

The answer is negative 5cd(in words) or - 5cd
