Tom goes to a restaurant and the food bill is $22. If he wants to give the waiter a 20% tip. What will the total cost of the meal be?

Answers

Answer: $4.40

Step-by-step explanation:

Trust me did the assignment

Answer:

$26.40.

Step-by-step explanation:

Find 20% of 22.

20% x 22 = 22/5 = 4 2/5 = 4.40.

So the tip costs 4.40, so let's add that to 22 to find the total cost. 4.40+22=26.40, so the entire meal costs: $26.40.

Solve systems of equations by substitution

Answers

Answer:

No solution.

Step-by-step explanation:

2x + y = 7

-2x - y = 6

From the first equation:

y = 7 - 2x

Plug this into the second equation:

-2x - (7 - 2x) = 6

-2x  + 2x = 6 + 7

0 = 13

We have 3y and are asked to express it equivalently with the answers provided.

I will go over the flaws of each answer and single it down to the correct one.

x * x * x would equal x^3, since this is being multiplied.

x^3 is equal to x * x * x, therefore it is not correct.

x + 3 is not correct because you cannot add numbers or variables that are not like terms, so it would not equal to 3y.

x + x + x would equal to 3y because they are all like terms and do not form exponents.

The number of measles cases decreases by 9 percent to 508 cases. What was the number of cases before the decrease

Answers

Answer:

558

Step-by-step explanation:

The original number of cases of measles was x.

x was 100% of the number of cases of measles.

The number of cases then went down by 9%.

100% - 9% = 91%

The number of cases now is 91% of the original number, or 91% of x. We are told the number now is 508, so 91% of x must equal 508.

91% of x = 508

0.91x = 508

x = 508/0.91

x = 558.241...

The local ranger station tracked and tagged 2,844 adult female black bears in a national park. A random sample of 9 adult female black bears from those tagged had an average body weight of 203 pounds with standard deviation 25 pounds. Which of the following is a point estimate for the population mean weight of all female black bears that are tagged?

a. 9
b. 25/√9
c. 25
d. 203
e. 2,844

Answers

Answer:

203

Step-by-step explanation:

Sample size, n = 9

Mean weight, m = 203

Standard deviation = 25

Point estimate for the population mean weight of all black bears that are tagged `

The point estimate of the population mean ;

ΣX / n

Sum of sample / sample size ;

This is the mean value formula for the sample.

However, since it has been given in the question that, sample mean weight value = 203 ; then the point estimate of the population mean weight = 203

Option d: 203 is a point estimate for the population mean weight of all female black bears that are tagged.

Given that:Total tagged adult female black bears in the national park = 2,844Sample size = 9Sample mean of body weight of female black bears = 203 pounds.To find:

Point estimate of population mean weight of female black bears that are tagged.

Calculations and explanations:

Point estimation of population mean is calculated by calculating the mean of the sample drawn from that population. This estimate is considered best guess of population mean.

The sample mean is obtained by:

[tex]\overline{x} = \dfrac{\sum \text{sample observations}}{\text{sample size}}[/tex]

Since it is given that the sample mean is 203, thus we have the point estimate of the population mean as 203 too.

Thus, 203 is a point estimate for the population mean weight of all female black bears that are tagged.
