10% of 90 is 9
5% of 90 is 4.5
1% of 90 is 0.9

So.. 9+4.5+0.9= 14.4

You first set up a proportion

16/100 = x/90

then cross multiply 16*90
and 100*x
1440 = 100x
divide each side by 100
1440/100 = 100x/100
100 cancels out on the right side
the answer is
14.4=x

Factor the expression using the GCF. 18x + 24y.

Georgia [21]

Answer: 6(3x + 4y)

1. Find the GCF (the largest number that goes into both 18x AND 24y). This would be 6.

2. Factor out the 6 by dividing each of the terms by the GCF
18x/6 = 3x
24y/6 = 4y

3. Write as a factored expression
6(3x + 4y)

Suppose you have a random variable that is uniformly distributed between 1 and 29. what is the expected value for this random va

Kryger [21]

Assuming the distribution is continuous, you have

$\mathbb E(X)=\displaystyle\int_1^{29}\frac x{29-1}\,\mathrm dx=\dfrac1{28}\int_1^{29}x\,\mathrm dx=15$

If instead the distribution is discrete, the value will depend on how the interval of number between 1 and 29 are chosen - are they integers? evenly spaced rationals? etc
