Answer: 1/18
Step-by-step explanation:
9 total marbles
2 red
so the first time he picks it would be a 2/9 chance of the marble being red
the second time there would be 8 total marbles and 2 red, so it would be a 2/8 or 1/4 chance.
the probability is found by doing 2/9*1/4 which equals 2/36 or 1/18.
Answer:
B. y+13=5(x+2)
Step-by-step explanation:
I personally do y=_+_(x-_) when solving these equations
Plug in -2 the x coordinate for (x- (-2) to be (x+3)
Plug in -13 for the y intercept.
5 from 5x is the slope.
Thus y=-13+5(x+3)
Then just move 13 to the other side
Percent means parts out of 100 so
10%=10/100
we know that 0.8358=8358/10000
8358/10000
make it over 100
move decimal
835.8/1000
83.58/100=83.58%
answer=53.58%
The answer to that would be 48
Answer:
56
Step-by-step explanation:
The n th term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₆ = 17 and a₁₃ = 38, then
a₁ + 5d = 17 → (1)
a₁ + 12d = 38 → (2)
Subtract (1) from (2) term by term to eliminate a₁
7d = 21 ( divide both sides by 7 )
d = 3
Substitute d = 3 into (1) and evaluate for a₁
a₁ + 5(3) = 17
a₁ + 15 = 17 ( subtract 15 from both sides )
a₁ = 2
Thus
= 2 + (18 × 3) = 2 + 54 = 56
