Aubree practices the piano 1197 minutes in 3 weeks. At what rate did she practice, in minutes per day?
Norma-Jean [14]

Answer:

57

Step-by-step explanation:

We need to create a ratio. so Aubree practices the piano for 1197 min: in 3 weeks. So for 1 week, we have to divide 1197 by 3, so 1197/=399. And so we know that 1 week is 7 days, just divide 399 by 7! 399/7=57. The rate that she practiced per day is 57 minutes. So one last final step just to check if this answer is correct is to divide 57 by 60, and that is 0.95. 0.95 out of 1.00 minutes per day is 95/100. Cross multiply with x/60, and you will get your answer, which is 57.

Find a 75% confidence interval for the population average weight μ of all adult mountain lions in the specified region. (Round y
kupik [55]

Answer:

75% confidence interval is 91.8±16.66. That is between 75.1 and 108.5 pounds.

Step-by-step explanation:

The question is missing. It is as follows:

Adult wild mountain lions (18 months or older) captured and released for the first time in the San Andres Mountains had the following weights (pounds): 69  104  125  129  60  64

Assume that the population of x values has an approximately normal distribution.

Find a 75% confidence interval for the population average weight μ of all adult mountain lions in the specified region. (Round your answers to one decimal place.)

75% Confidence Interval can be calculated using M±ME where

  • M is the sample mean weight of the wild mountain lions (\frac{69 +104 +125 +129+60 +64}{6} =91.8)
  • ME is the margin of error of the mean

And margin of error (ME) of the mean can be calculated using the formula

ME=\frac{t*s}{\sqrt{N} } where

  • t is the corresponding statistic in the 75% confidence level and 5 degrees of freedom (1.30)
  • s is the standard deviation of the sample(31.4)
  • N is the sample size (6)

Thus, ME=\frac{1.30*31.4}{\sqrt{6} } ≈16.66

Then 75% confidence interval is 91.8±16.66. That is between 75.1 and 108.5

Tomas Briggs and Sons reviewed their first year operations. Gross sales were $204,000 Customer returns and allowances were $18,0
Masteriza [31]

Answer:

Percentage of total net sales = 91.17%

The percentage of cost of merchandise sold = 44.11 %

Percentage of First year expenses = 41.17 %

Percentage of Overall profit = 5.88 %

Step-by-step explanation:

Given:

Gross sales= $204,000

Customer returns and allowances = $18,000

Cost of the merchandise they sold = $90,000

overall profit before taxes = $12,000

Now,

The Net sales = Gross sales - sales returns  

or

The net sales = $204,000 - $18,000 = $186,000

Thus,

Percentage of total net sales = \frac{\textup{Net sales}}{\textup{Gross sales}}\times100

or

Percentage of total net sales = \frac{186,000}{204000}\times100

or

Percentage of total net sales = 91.17%

Now,

The percentage of cost of merchandise sold = \frac{\textup{cost of the merchandise sold }}{\textup{Gross sales}}\times100

or

The percentage of cost of merchandise sold = \frac{\textup{90,000}}{\textup{204,000}}\times100

or

The percentage of cost of merchandise sold = 44.11 %

And,

Percentage of First year expenses = \frac{\textup{Expenses}}{\textup{Gross sales}}\times100

or

Percentage of First year expenses = \frac{\textup{84000}}{\textup{204000}}\times100

or

Percentage of First year expenses = 41.17 %

also,

Percentage of Overall profit = \frac{\textup{Overall profit}}{\textup{Gross sales}}\times100

or

Percentage of Overall profit = \frac{\textup{12,000}}{\textup{204,000}}\times100

or

Percentage of Overall profit = 5.88 %
