Complete the ratio table.to convert the units of measure from ounces to grams or to ounces ?

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Set this up as a proportion with oz on the top and grams on the bottom and then fill in with what you are given:

$(oz)/(g):(1)/(28)=(3)/(x)$

Cross multiply to get x = 28*3 so x = 84 g

Do the same for the next ratio:

$(oz)/(g):(1)/(28)=(x)/(140)$ and cross multiply again to get

28x = 140 so

x = 5 oz

Answer 2

Answer:

Answer:

Ounces Grams

1 28

3 84

5 140

Step-by-step explanation:

Since one ounce is 28 grams you would do 3 times 28 which gives you 84 and so 3 ounces if equal to 84 grams. Now we have to find how many ounces in 140 grams. We would do 140 divided by 28 which gives us 5 and so 140 grams is equal to 5 ounces. Hope this helps! If not well...

John receives two credit card offers in the mail. Credit Card A: 1% introductory APR, 19.9% APR for purchases after the introductory period, and 22.9% APR for cash advances. Annual membership fee: $0. Credit Card B: 0% introductory APR, 20.9% APR for purchases after the introductory period, and 24.9% APR for cash advances. Annual membership fee: $0. What would be a valid reason for John to choose one card over the other? Select the best answer from the choices provided. A. John chooses Credit Card A because any purchases he makes after the introductory APR period will have a 1% APR because of the annual membership fee of $0. B. John chooses Credit Card B because he will not have to pay any interest on a cash advance if he makes his payments by the due date. C. John chooses Credit Card A because he will not have to pay any late fees if he makes a payment after the due date since he has $0 annual membership fee. D. John chooses Credit Card B because he will not have to pay any interest on his purchases during the introductory APR period.

Pedro bought lb of red sand and lb of brown sand to refill his sand box. Both types of sand cost $4.60 a pound. How much did Pedro spend on the sand? A. $29.85 B. $31.05 C. $33.05 D. $33.75

Answers

If we know that Pedro bought 1 $(1)/(4)$ pounds of red sand, and 5 $(1)/(2)$ pounds of brown sand, and they both cost $4.60, then we just have to add the individual amounts of sand, since they cost the same.

$1 (1)/(4) + 5 (1)/(2) = 6 (3)/(4)$

So Pedro bought $6 (3)/(4)$ lbs of sand overall. Now, we just need to multiply the cost per pound by the total amount of sand he bought.

$6 (3)/(4) * 4.6 = 31.05$

Pedro spent $31.05 on sand, which is answer choice B.
Hope that helped =)

b. $31.05
5.5 + 1.25 = 6.75
6.75 * $4.60 = $31.05

I NEED HELP NOW!!!!! The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the outlier is included, then the mean is 84. Which statement is always true about the new data when the outlier is removed? The mean would decrease
. The mean would increase.
The median would decrease.
The median would increase.

Answers

The median would decrease. The correct option is C.

What is the median?

The average is the value obtained by dividing the sum of the data values by the number of data points, and the median is the midpoint of the given data points. However, for evenly spaced numbers like 2, 4, 6, 8, and 10, the median and average, or 6, are the same.

There are 16 observations in total in this question, and their average is 80. An anomaly with the value 91 exists. This demonstrates that the outlier is greater than the mean. The mean formula is:

Mean = Sum of observations/Number of Observations.

The sum of observations can be calculated by substituting the values in the above formula.

80 = Sum/16.

Sum = 80*16 = 1280.

Subtracting 91 from the total sum will give the sum of the rest of the 15 non-outlier values. Therefore 1280 - 91 = 1189.

Calculating the mean of the 15 values:

Mean = 1189/15 = 79.267 (correct to 3 decimal places).

It is evident that eliminating the outlier lowers the mean. As a result, C is the right response. Since actual values are needed to calculate the median but are missing, the information about the median cannot be determined. C is therefore the right answer.

Answer:

Option C (The mean would decrease).

Step-by-step explanation:

In this question, there are 16 observations and their mean is 80. There is an outlier which has the value 91. This means that the outlier is on the greater side of the mean. The formula for mean is:

Mean = Sum of observations/Number of Observations.

Sum of observations can be calculated by substituting the values in the above formula.

80 = Sum/16.

Sum = 80*16 = 1280.

Subtracting 91 from the total sum will give the sum of rest of the 15 non-outlier values. Therefore 1280 - 91 = 1189.

Calculating the mean of the 15 values:

Mean = 1189/15 = 79.267 (correct to 3 decimal places).

It can be seen that removing the outlier decreases the mean. Therefore C is the correct answer. The information regarding the median cannot be determined since actual values are not present, which are required to calculate the median. Therefore, C is the correct choice!!!
