75%

15/20 = 75/100 (you just have to multiply both top and bottom by five)

75%

Step-by-step explanation:

To make a fraction into a percent you have to multiply it by 100

So: 15/20 x 100=15x5=75 so he got 75% of his problems right

Remember that
1) For functions f(x)

and

, $\int {f(x) + g(x)} \, dx = \int {f(x)} \, dx + \int {g(x)} \, dx$
2) For a function f(x)

and a constant

, $\int {cf(x)} \, dx = c \int {f(x)} \, dx$

Using these two properties of integrals, and the fact that $\int\limits^3_1 {e^x} \, dx = e^3 - e$ , we can see that

$\int\limits^3_1 {5e^x - 1} \, dx$
$= \int\limits^3_1 {5e^x} \, dx - \int\limits^3_1 1} \, dx$
$= 5 \int\limits^3_1 {e^x} \, dx - \int\limits^3_1 1} \, dx$
$= 5(e^3 - e) - \left.x\right|_1^3$
= 5e^3 - 5e - (3 - 1)

$= \bf 5e^3 - 5e - 2$
