The probability of picking a green marble the first time is 3/20 and the probability of picking a yellow marble the second time is 8/20.
probabilities are heavily related to percents so it would make sense that the probability of picking a color would be the number of that color divided by the total number.
note that it is really important that the problem said that the marble was replaced. If the marble was not replaced, the probability of picking a yellow marble the second time would be 8/19 if the first marble picked was not a yellow one.
I hope this helps.
The value of x would equal 55
Answer:
91m + 13n + 52
Step-by-step explanation:
13(n + 4 + 7m)
= (13) (n+4+7m)
= (13) (n) + (13) (4) + (13) (7m)
= 13n + 52 + 91m
= 91m + 13n + 52
hope this helps and is right :)
p.s. i really need brainliest
Short Answer A is the bad guy. <<<<
The line should read
The large square area = the 4 triangles + the inner square.
(a + b)^2 = c^2 + 4 ( 1/2 * ab)
(a + b)^2 = c^2 + 2 ab
Answer:
no
Step-by-step explanation:
let x=12 and y=25 and substitute:
does 25 = 2(12)+2?
no, 25 ≠ 26
