PLEASE HELP i need to do this test or i can't play ROBLOX anymore *cries in ewf*

valuate 4 j + t^2 over 3

j = - 3 and t = 6

This is Confusing my friend...j=1. Hope I helped

Step-by-step explanation:

Rewrite the equation

Cancel out the common factor

Numerators MUST be equal sinse the expression on each side of the equation has the same denominator

Divide each term by  2  and then you have to simplify it :)

50- 250 is correct i did that one too

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
