Gloria earned a total of $810 over the summer. She earned $162 babysitting and the rest
from mowing lawns. Which bar model and solution represent x, the amount of money Gloria
earned mowing lawns?

Answers

Answer 1

Let x represent the amount of money Gloria  earned mowing lawns.

We have been given that Gloria earned a total of $810 over the summer. She earned $162 babysitting and the rest  from mowing lawns.

The total amount earned by Gloria would be amount earned from baby sitting and lawn mowing that is [tex]x+162[/tex].

Now we will equate total earnings of Gloria by 810 as:

[tex]x+162=810[/tex]

[tex]x+162-162=810-162[/tex]

[tex]x=648[/tex]

Therefore, Gloria earned $648 from mowing lawns.

Answer:

The answer is that the y-coordinate should be -3 1/2.

Step-by-step explanation:

First, look at the graph. On the x-axis, the dot is at -5, since it is 5 units to the left of the origin. On the y-axis, the dot is at -3 1/2. It is between -3 and -4, not -4 and -5. Therefore, the answer is that the y-coordinate should be -3 1/2, not -4 1/2. You can also check by seeing if -4 1/2 is reasonable. -4 1/2 would mean the dot would be more than 4 units below the origin. On the graph, the dot is clearly above the -4 mark, so the -4 1/2 must not be correct.

A local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. The owner has randomly selected 23 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 34 minutes. Suppose the P-value for the test was found to be 0.0290. State the correct conclusion

Answers

Answer:

We conclude that the mean delivery time actually exceeds 34 minutes.

Step-by-step explanation:

We are given that the owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes.

The owner has randomly selected 23 customers and has delivered pizzas to their homes in order to test if the mean delivery time actually exceeds 34 minutes. Suppose the P-value for the test was found to be 0.0290.

Let [tex]\mu[/tex] = average time spent on the deliveries.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] [tex]\leq[/tex] 34 minutes    {means that the mean delivery time is less than or equal to 34 minutes}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 34 minutes     {means that the mean delivery time actually exceeds 34 minutes}

Now, the decision rule based on the P-value to whether null hypothesis should be accepted or rejected is given by;

If the P-value of test statistics is less than the level of significance, then we will reject our null hypothesis.If the P-value of test statistics is more than the level of significance, then we will not reject our null hypothesis.

Here, we assume that the level of significance is 5%.

Since, the P-value of test statistics is less than the level of significance as 0.029 < 0.05, so we have sufficient evidence to reject our null hypothesis.

Therefore, we conclude that the mean delivery time actually exceeds 34 minutes.

Two trains leave stations 390 miles apart at the same time and travel toward each other. One train travels at 70 miles per hour while the other travels at 80 miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.

Answers

Answer:

Let's denote:

x: the time both trains traveled.

Then, we have:

70x + 80x = 390

=> 150x = 390

=> x = 390/150 = 2.6 hour

Answer:

2.6 hours ( or 2 hours 36 minutes).

Step-by-step explanation:

The combined speed is 70+80 = 150 mph.

Speed = distance / time,  so time = distance / speed.

So the time when they will meet

=  390 / 150

= 2.6 hours.

The ratio of the number of student in mr. Moore’s class compared to the number of student in miss Henry’s class is 5:4.

Wilson’s class?

Answers

Answer:

10:9

Step-by-step explanation:

First ratio is 5:4. 4 is equal to Henry class

If you múltiply the ratio by 2 you get

10:8, This ratio can be compared because now Henry class has 8

2(5:4)

10:8

8:9

Meaning that the answer is 10:9

The require ratio of number of students in Mr. Moore's class to Mr. Wilson's class is 10:9

What is Ratio?

The ratio can be expression as how many times one number contain another number.

For example, If any bag contain 4 apples and 8 oranges then the ratio of apple to orange is 4:8 while the ratio of the orange to the apple is 8:2

How to find ratio?

Consider M denote the number student present in the Mr. Moore's class

similarly H denote the number of student in miss Henry's class and W denote the number of student present in Mr. Wilson's class

then we have given that

M : H = 5 : 4 or

[tex]\frac{M}{H} = \frac{5}{4}[/tex]

Also we have H : W = 8 : 9

[tex]\frac{H}{W} = \frac{8}{9}[/tex]

Now multiply these two equations we have

[tex]\frac{M}{H}\times \frac{H}{W}=\frac{5}{4}\times\frac{8}{9}[/tex]

[tex]\frac{M}{W}= \frac{10}{9}[/tex]

The ratio of number of student in Mr. Moore's class to Mr. Wilson's class is 10:9

The owner-operator of a hardware store in a Virginia suburb along the banks of the Potomac River wants to learn several things about his customers and his business. Over the past 5 years, he has kept meticulous records on the contact information for his most frequent customers through a point-of-sale information system his cashiers use. He offers attractive discounts on every purchase to customers who have provided their contact information (name, phone number, home address, e-mail address) for inclusion in the database. When the customer provides his/her phone number to the cashier during checkout, the discount is activated in the cash register and all information about the purchase (products, quantities, prices) is captured by the point-of-sale system and stored in the master database. The system tracks the number of check-outs made by database customers vs. check-outs made by customers not in the database. In the past year, 80% of the 50,000 checkouts have been made by customers in the database. The owner-operator wants to survey his customers to learn their level of satisfaction with his business and to learn their attitudes toward certain changes he is contemplating.


Which of the following survey methods would most likely produce a representative sample of the owner's customer population at the least cost:

a. telephone calls to 5,000 randomly selected people in the Virginia suburb where the store is located
b. mailers to 5,000 randomly selected homes in the same zip code as the store

a. Do you like our store hours during the winter season?
b. How likely is it that you will make your next hardware purchase from our store?
c. Would you buy more from our store if we lowered our prices?
d. Which of our competitors do you buy from when you do not buy from our store?

Which of the following is the best the method for randomly selecting customers for the survey to produce representative results:

a. choose young adults aged 25-40 for the survey
b. choose half men and half women for the survey
c. assign numbers to each customer record and use a random number generator to pick customers for the survey
d. choose customers with last names that begin with a vowel

Which of the following statements is most correct about the minimum size of the sample required for confidence in the results?

a. the minimum size of the sample is 10
b. the minimum size of the sample depends upon the size of the population
c. the minimum size of the sample depends on the level of confidence required in the result
d. the minimum size of the sample depends on the standard deviation of the population

Which of the following statements is most correct about response rates and sample sizes?

a. It is preferable to have a high response rate from a randomly chosen small sample.
b. it is preferable to have a low response rate from a randomly chosen large sample.

Answers

Answer:

12.12%

Step-by-step explanation:

We have that the formula is given by:

A = p * e ^ (r * t)

From here, we know that A = 200000; p = 20000 and the time we can calculate 40 - 21 = 19

if we replace we have:

200000 = 20000 * e ^ (19 * r)

we must calculate r:

e ^ (19 * r) = 200000/20000

e ^ (19 * r) = 10

19 * r = ln 10

r = ln 10/19

r = 0.1212
