P(Q and R) = P(Q) *P(R) =0.2*0.4=0.08
Answer:
585
Step-by-step explanation:
let 'f' = females
based on sample, set up this proportion:
32/75 = f/1371
cross-multiply:
75f = 1371(32)
75f = 43872
f = 584.96
Answer:
4h
Step-by-step explanation:
Expression: 4h-8h=4h
Because both 4h and 8h end in the same variable they can be subtracted when you subtract 4 and 8 you get 4. and You can't forget your variable so you end with 4h
Your expression is a group of terms without an equal sign. 4h and 8h are your terms as well as your answer.
Your expression ends as 4h-8h=4h
coefficients are the whole number.
Example : 1x+5x
________ + 15
3x+16x
that's a fraction the coefficients would be the numbers in front of the variable. Variables are the letters in the equation. Which is the x in my equation.
5, since 10 to the fifth power is 100,000
