Keep that Michelle went out To dinner. The total cost of the meal, including the tip, came out to $53.70. It's a combined tip came out to $9.60 and each friend spent an equal amount, how much did each friend pay not including the tip?

Answers

The question is incomplete:

Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?

Answer:

Each friend paid $22.05 without including the tip.

Step-by-step explanation:

Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:

$53.70-$9.60=$44.1

$44.1/2=$22.05

According to this, the answer is that each friend paid $22.05 without including the tip.

Convert the following equations from point-slope form to slope-intercept form.

9) y – 4 = 3(x – 1)

10) y – 1 = -4(x – (-3))

Answers

Answer:

We need to solve both for y.

#9:

[tex]y - 4 = 3(x - 1)\\\\y - 4 = 3x - 3\\\\y = 3x + 1[/tex]

#10:

[tex]y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11[/tex]

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.

Answers

Answer:

Average rate of change between x = 3 to x = 5 is 0.

Step-by-step explanation:

Given quadratic function s passing through two points (3, 0) and (5, 0).

Average rate of change of a function between x = a and x = b is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the graph attached,

Average rate of change between x = 3 to x = 5 will be,

= [tex]\frac{f(5)-f(3)}{5-3}[/tex]

= [tex]\frac{0-0}{5-3}[/tex]

= 0

Therefore, average rate of change between x = 3 to x = 5 is 0.

Answer: The average rate of change for the given graph from x=3 to x=5 is 0

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

n = 5m

n = 2/3m - 13

Step 2: Solve for m

Substitution

Substitute in n:                                 5m = 2/3m - 13Subtract 2/3m on both sides:          13/3m = -13Divide 11/3 on both sides:                m = -3

Step 3: Solve for n

Define equation:                    n = 5mSubstitute in m:                      n = 5(-3)Multiply:                                  n = -15

Answer:

Step-by-step explanation:

5m = 2/3m - 13

15m = 2m - 39

13m = -39

m = -3

n = 5(-3)

n = -15

The sales tax on a $750 computer at T&C Computers is $75. What is the sales tax rate? BTW

ANSWER IS 10%

Answers

Answer:

10%

Step-by-step explanation:

Price of computer = $750

Amount of sales tax = $75

Sales tax rate = Amount of sales tax / Price of computer × 100

= $75 / $750 × 100

= 0.1 × 100

= 10%

Sales tax rate = 10%

Sales tax rate = 10% of selling price

A manager of the credit department for an oil company would like to determine whether the mean monthly balance of credit card holders is equal to $75. An auditor selects a random sample of 100 accounts and finds that the mean owed is $83.40 with a sample standard deviation of $23.65. If you were to conduct a test to determine whether the auditor should conclude that there is evidence that the mean balance is different from $75, which test would you use? a) Z-test of a population mean b) Z-test of a population proportion c) t-test of population mean d) t-test of a population proportion

Answers

Answer:

c) t-test of population mean

Explanation:

The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.

Example we compare our test variable to the hypothesized mean value $75 above.

The t test is used instead of z score when standard deviation is unknown.

Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.
