One rate of an equivalent ratio is 9/n. Select two other rates, one that can be solved using equivalent fractions, and the other that can be solved with unit rates

Answers

Answer 1

Answer: The values given is not sufficient.
However, the rates could 18/2n or 90/10n

In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.

57.80 - 4.07

= 57.80 - 4.00 - 0.07

= 53.80 - 0.07

= 53.73

1st when you start to subtract decimals you line them up
so 57.8
-4.07
_______
Next you need to act like the decimal point is not there, then subtract then add the decimal point.
The answer would be....

E.) 14

Answers

Well, 1/2*7=3.5. So you have to do each equation to see which ones are not equal to 3.5. A) 1*7=7/2=3.5 so A is not the right answer. B) 1/2*7=1/14=.07, so B is one of the correct answers. C) 1*7=7*2=14, so C is another one of the correct answers. D) 1*7/2=7/2=3.5, so D is not a correct answer. E) 14 is not equal to 3.5, so E is another correct answer. So the correct answers are B, C, and E.

B, C, and D are incorrect.

14. The mode of the data set is 21. What number is missing?21, 17, _, 25, 23, 13

19. The mean of the data set is 18. What number is missing?

21, 11, _, 27, 22, 13, 16

20. The median of the data set is 81. What number is missing?

82, 87, _, 77, 70, 80, 88

14. The missing number would be 21, which makes the 21 the mode.

19. The missing number of the data set with a mean of 18 is: 16.

20. The missing number would be 81, which is the median.

What is the Mode, Mean, and Median of a Data?

The mode is the data point that appears the most in a data set.

The median is the middle value or average of the middles values in a an ordered data set.

The mean is the average value of the data set.

14. The missing number would be 21, which makes the 21 the mode.

19. Mean = (21 + 11 + x + 27 + 22 + 13 + 16)/7 = 18

110 + x/7 = 18

110 + x = (18)(7)

110 + x = 126

x = 126 - 110

x = 16

Therefore, the missing number of the data set with a mean of 18 is: 16.

20. Let the missing number be x, then order the data set:

70, 77, 80, x, 82, 87, 88

The missing number would be 81, which is the median.

14. The mode is the number in a data set that happens most frequently. Since we have a 21 and the mode is 21 then the missing number has to be 21.

19. The mean is the average of all the data in the set. That means...

(X+21+11+27+22+13+16)÷7= 18

X + 110/7 = 18
X + 110 = 126
X = 16

The missing number is 16

20. The median is the central number in a data set. Put the numbers in order...

70, 77, 80, __, 82, 87, 88

It tells us that 81 is the median, so that has to be the missing number because it fits as the central number (the middle number in the data set). There are 3 numbers before it and after it.

Missing number is 81

A shuttle bus makes 4 round-trips between 2 shopping centers each day. The bus holds 24 people. If the bus is full on each one-way trip, how many passengers are carried by the bus each day?

Answers

The bus makes four round trips, which means that it will go a total of 8 times: 4 times twice.

And on each of those 8 journeys, it will take with it 24 people.

So we have to multiply 24 by 8: this is 192.

so each day the bus carries 192 people.
