When dividing 918 by 4.2, what number should the divisor be multiplied by in order to make it a whole number?

Alexandra [31]

B. Because the divisor, 4.2, has only value in the ones and tenths places, so we only have to multiply by 10 to get to 42, which is the whole number you need.

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

15a^3b^4c^5----> answer B

you can only multiple like terms so

(5x3)= 15

now just add

a+a^2= a^3

b + b^3 = b^4

c^5 + 0= c^5
