Find the area of the trapezoid with bases 5cm and 2cm and height 1/5 cm.

(Simplify your answer)

Answers

Answer:

Step-by-step explanation:

[tex]\frac{(5 + 2) * \frac{1}{5} }{2}[/tex] = [tex]\frac{\frac{7}{5}}{2}[/tex] = [tex]\frac{1.4}{2}[/tex] = 0.7, rounded to the nearest ones is 1.

Answer:

0.7

Step-by-step explanation:

The formula for the area of a trapezoid is (A+B)÷2×H

So our formula is (5+2)÷2×1/5

5+2=7

7÷2=3.5

3.5×1/5=0.7

That's why the answer is 0.7

If a manufacturer's list price is $800 and Bill's Outlet buys the goods for $650, what is the trade discount percent? (Round answer to
the nearest hundredth percent)

Answers

Answer:

The discount percent is 18.75%

Step-by-step explanation:

The amount of money that was lost in this discount is $150, to calculate the percent, you subtract the original price by the discounted price, and then divide the difference by the original price and multiply that by 100% to get the discount percent. [tex]\frac{150}{800}[/tex] * 100% equals 18.75%, so that would be the discount percent.

Jeff Brown has collected sales data for his cupcake stand. Calculate the exponential smoothing forecast for period 13 with α = 0.4. And F2 = A1. Round your answers to 2 decimals. Time 1 2 3 4 5 6 7 8 9 10 11 12 Sales 48 41 37 32 36 31 43 52 60 48 41.9 29.7

Answers

Answer:

The exponential smoothing forecast for period 13 = 39.68

Step-by-step explanation:

As given,

[tex]\alpha[/tex] = 0.4

Time Sales forcast

1 48

2 41 48

3 37 48 + [tex]\alpha {(41 - 48)}[/tex] = 45.2

4 32 45.2 + [tex]\alpha {(37 - 45.2)}[/tex] = 41.92

5 36 41.92 + [tex]\alpha {(32 - 41.92)}[/tex] = 37.95

6 31 37.95 + [tex]\alpha {(36 - 37.95)}[/tex] = 37.17

7 43 37.17 + [tex]\alpha {(31 - 37.17)}[/tex] = 34.70

8 52 34.70 + [tex]\alpha {(43 - 34.70)}[/tex] = 38.02

9 60 38.02 + [tex]\alpha {(52 - 38.02)}[/tex] = 43.61

10 48 43.61 + [tex]\alpha {(60 - 43.61)}[/tex] = 50.17

11 41.9 50.17 + [tex]\alpha {(48 - 50.17)}[/tex] = 49.30

12 29.7 49.30 + [tex]\alpha {(41.9 - 49.30)}[/tex] = 46.34

13 46.34 + [tex]\alpha {(29.7 - 46.34)}[/tex] = 39.68

∴ we get

The exponential smoothing forecast for period 13 = 39.68

a. Explain in words what is done to the input value (20) to produce the output value (y).
b. Write the rule you described in part (a) with algebraic symbols.

Answers

Answer:

(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product

(b) [tex]y =2x +5[/tex]

Step-by-step explanation:

Given

The attached table

Solving (a): The rule of the table in words

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Using:

[tex](x_1,y_1) = (2,9)[/tex]

[tex](x_1,y_1) = (10,25)[/tex]

So, we have:

[tex]m = \frac{25 - 9}{10 - 2}[/tex]

[tex]m = \frac{16}{8}[/tex]

[tex]m=2[/tex]

The equation is calculated using:

[tex]y - y_1 =m(x - x_1)[/tex]

Using:

[tex](x_1,y_1) = (6,17)[/tex]

We have:

[tex]y - 17 =2(x - 6)[/tex]

[tex]y - 17 =2x - 12[/tex]

Make y the subject

[tex]y =2x - 12+17[/tex]

[tex]y =2x +5[/tex]

Hence, the rule is:

Multiply the input (x) by 2 and add 5 to the result of the product

(b): The rule, in algebra

As solved in (a), the rule is:

[tex]y =2x +5[/tex]

A local radio station conducted a survey about stay-at-home parents by randomly dialing home numbers on weekdays until responses from 500 adults were collected. Twenty-six percent of those who responded said they were stay-at-home parents. In reality, only four percent were actually stay-at-home parents at the time of the survey. Which of the following best explains the difference in the two percentages?

a. The difference is due to voluntary response. Adults are able to volunteer as members of the sample.
b. The difference is due to undercoverage bias. The survey included only adults with telephones.
c. The difference is due to response bias. Adults who are stay-at-home parents are likely to say they are employed outside the home.
d. The difference is due to sampling variability. We should not expect the results of a random sample to match the truth about the population every time.
e. The difference is due to nonresponse bias. Adults who are stay-at-home parents are more likely to be available for the sample than adults who are employed outside the home.
