7.5% of 20......turn ur percent to a decimal by dividing it by 100...
7.5 / 100 = 0.075..." of " means multiply....0.075(20) = 1.5 <=
Yasim is Albert who ran the race at a time that was 15.7 seconds shorter, So, Yasim is the student who improved the most by decreasing the time needed to run the race.
<h2>Given that,</h2>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
<h3>We have to
find,</h3>
Which student improved the most by decreasing the time needed to run the race?
<h3>
According to the
question,</h3>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
In the given option Yasim has the lowest value of the time which is -37.5 seconds.
Yasim was the most improved student because Yasim ran the second race in a time that was 37.4 seconds shorter than the first race.
Following Yasim is Albert who ran the race at a time that was 15.7 seconds shorter.
At the third place in improvement is Cody who actually was worse off than the first race along with the 4th place Hannah.
Hence, Yasim students improved the most by decreasing the time needed to run the race.

The answer is additive property
The value of the function f(x)=6/-2+2
at x=4 after rounded to the nearest tenth is -2.4.
Given Function of x : f(x)=6/-2+2
The given function showing the relationship between x and f(x) is f(x)=6/-2+2
where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.
f(4)=6/-2+2
( The value of e is 2.7812)
f(4)=-3+2
f(4)=-3+2*0.30119 (The value of
is 0.30119)
f(4)=-3+0.60238
f(4)=-2.3972
Round -2.3972 to tenth is -2.4.
Hence the value of function of at x=4 is -2.4.
