Answer:

so let's call the unknown number x.

-5/4 x X = 7/2

by changing the subject, X = 7/2 / -5/4

to divide fractions, we turn the fraction we're dividing by upside down and change the sign to multiplication. so X = 7/2 x 4/-5

after multiplying, X =>28/-10

simplified, X = 14/-5

A set of data is described as:
Savatey [412]

The group of measures which would lead to the provided conclusion is the range is 7, the mean of the data is 12, the median is 12 and the mode is 11.

Given that, the data is around 12. If another measurement were taken, it would probably be around 12.

We need to find which group of measures would lead to this conclusion.

<h3>What are the mean, median and mode of the data set?</h3>

The mean of the data is the average value of the given data. The mean of the data is the ratio of the sum of all the values of data to the total number of values of data.

The median of the data is the middle value of the data set when it arrange in ascending or descending order. The data is around 12 which suggests that the median is 12.

Median=12

The mode of a data set is the value, which occurs most times for that data set. The value which has the highest frequency in the given set of data is known as the mode of that data set.

Mean and mode is around the median. For this case, the mean of the data is 12 and the mode is 11.

Mode=11

Mean=12

Thus, the group of measures which would lead to the provided conclusion is the range is 7, the mean of the data is 12, the median is 12 and the mode is 11.

Fraction word problems Your strip of paper represents one lap on a track. Three students ran a relay and took turns running equa
artcher [175]

Answer:

A quarter (\dfrac{1}{4}) of one lap of the track.

Step-by-step explanation:

Three students ran ran a relay and took turns running equal parts of the track.

The race was three-fourths of a lap long.

Let the length of one lap of the track=x

The length of the race=\frac{3}{4}x

Since each of the students ran equal part,

Length run by each student

=\dfrac{3}{4}x \div 3\\=\dfrac{3}{4}x X \dfrac{1}{3}\\=\dfrac{1}{4}x

Therefore, each student ran a quarter (\dfrac{1}{4}) of one lap of the track.

Plzz hellp :( i will mark you the brainlist if some on helps (A rectangular prism has a length of 1 1/4 yards, a width of 2 1/2
Veseljchak [2.6K]
The volume of rectangular prism is the product of its length, width and height. 
So the volume V of prism with length 1 \frac{1}{4} yards, width 2 \frac{1}{2} yards and height of 4 yards will be:

V=1 \frac{1}{4} * 2 \frac{1}{2} *4 \\  \\ &#10;V=  \frac{5}{4}* \frac{5}{2}*4 \\  \\ &#10;V= \frac{25}{2} \\  \\ &#10;V=12 \frac{1}{2}

Thus the volume of prism as a mixed number in simplest form will be 12 \frac{1}{2} cubic yards
