Answer:

Sarah need to run 1\frac{1}{2} more miles.

Step-by-step explanation:

In order to tell how much more she needs to run we need to find out how much she ran so far. Since we know that one lap is \frac{1}{4} of a mile, and that she ran 14 laps we can easily find out how much she ran so far by multiplying \frac{1}{4} by 14. And so we get......

(\frac{1}{4} )(14) = \frac{14}{4} = 3\frac{2}{4} = 3\frac{1}{2}

Now that we know how much she ran so far (3\frac{1}{2} miles), in order to find out how much more she has to run we just have to substract the distance she ran so far from the total distance she wants to reach (in our case 5 miles) . After doing this we get the answer which is......

5 - 3\frac{1}{2} = \frac{5}{1} - \frac{7}{2} = \frac{10}{2} - \frac{7}{2} = \frac{3}{2}  = 1\frac{1}{2}

Find the sum of deviation of all observations of the data 5, 8, 10, 15, 22 from their mean.​
ivann1987 [24]

Answer:

the sum of deviation of all observations of the data 5, 8, 10, 15, 22 from their mean. =26

Step-by-step explanation:

Mean=sum of observation/ No. of observation

={5+8+ 10+ 15 + 22}/5

=60/5=12

Sum of deviations

= |5- 12| + |8 – 12| + |10- 12| + |15- 12| + |22-12|

= 7+4+2+ 3+ 10

= 26

George walked around the entire perimeter of his rectangular garden. The length of his garden was 12 yards and the width was 8 y
Marina86 [1]
To find perimeter, you use this equation for a parallelogram:
2l+2w=p
Let’s not put the numbers in,
2(12)+2(8)
24+16
40
So b, 40 yards is how much he walked.

A 50 coat is put on sale for 35 <br> What percent is the decrease?
IRISSAK [1]

so the coat went down from 50 to 35, namely 15.

if we take 50 to be the 100%, what is 15 off of it in percentage?


\bf \begin{array}{ccll} aount&\%\\ \cline{1-2} 50&100\\ 15&x \end{array}\implies \cfrac{50}{15}=\cfrac{100}{x}\implies \cfrac{10}{3}=\cfrac{100}{x} \\\\\\ 10x=300\implies x=\cfrac{300}{10}\implies x=30
