5/10+3/10

Answers

Rules in adding fractions:

1) Make sure that they have common denominator.
5/10 + 3/10

2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator

5/10 + 3/10 = (5 + 3)/10 = 8/10

3) Simplify the fraction
8/10 can still be simplified into 4/5

8 ÷ 2 = 4
10 ÷ 2 = 5

5/10 + 3/10 = 4/5

add 5+3= 8 then to make it in simplest form divide it by 2 until you can't

Robert is using the following data samples to make a claim about the house values in his neighborhood:House Value
A $250,000
B $275,000
C $300,000
D $267,000
E $250,000

Based on the data, should Robert use the mean or the median to make an inference about the house values in his neighborhood?
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

Answers

Both mean and median are measures of the center of a set of data.
Mean is normally preffered to the median except if there is an outlier that has a tendency to affect the mean.
An outlier is a data point that significantly differs from the other data points in a sample.
In the data set above, there is no outlier that will affect the mean.
Therefore, he should use the mean because there are no outliers that affect the mean.

-1/2u + 3/5= 1/6. What is u?

Answers

So to start off on answering we are going to subtract 3/5 from both of the sides:
−1/2u+3/5−3/5=1/6−3/5
−1/2u=−13/30
Okay, so now we are going to multiply both sides by 2/(-1):
(2/−1)*(−1/2u)=(2/−1)*(−13/30)
The final answer shall be:
u=13/15
I hope this helps!

arnold full workout consist of 10 minutes of warm-up exercises, 25 minutes of lifting weights, and 15 minutes on the treadmill. What was the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout?

Answers

The ratio of the number of minutes Arnold lifted weights to the total number of minutes is 1:2 or 1 / 2.

What is ratio?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

Given:

Arnold full workout consist of 10 minutes of warm-up exercises, 25 minutes of lifting weights, and 15 minutes on the treadmill,

Calculate the total time of the work-out as shown below,

Total time of workout = Time of warm-up exercises + Time of lifting weights + Time on the treadmill

Total time of workout = 10 + 25 + 15

Total time of workout = 50 minutes,

Calculate the ratio of the number of minutes he lifted weights to the total number of minutes as shown below,

The ratio of the number of minutes he lifted weights to the total number of minutes = Time of lifting weights / Total time of workout

The ratio of the number of minutes he lifted weights to the total number of minutes = 25 / 50

The ratio of the number of minutes he lifted weights to the total number of minutes = 1 / 2.

What is the means-to-MAD ratio of the two data sets, expressed as a decimal?Data set Mean Mean absolute deviation (MAD)
1 10.7 2.4
2 13.7 2.5

Answers

You have to calculate two separate measures, one for each set.The mean-to-MAD ratio is the mean divided by the MAD, i. e. mean / MAD. For the set 1, mean = 10.7 and MAD = 2.4, then mean / MAD = 10.7 / 2.4 = 4.4583. For the set 2, mean = 13.7 and MAD is 2.5, so mean/ MAD = 13.7 / 2.5 = 5.480.
