Answer:
92
Step-by-step explanation:
let 'q' = score on last quiz
<u> 70 + 75 + 83 + 80 + q </u> ≥ 80
5
cross-multiply:
308 + q ≥ 5(80)
308 + q ≥ 400
q ≥ 92
The Probability that Robert randomly pulls out a black sock is 1/5 .
In the question ,
it is given that
Total number of socks in sock drawer = 30 socks
number of white socks in the drawer = 16 socks
number of black socks in the drawer = 6 socks
number of red socks in the drawer = 2 socks
number of yellow socks in the drawer = 6 socks
So , the probability that he randomly pulls out a black sock = (number of black socks in the drawer) / ( total number of socks in the drawer )
= 6 / 30
= 1/5
Therefore , The Probability that Robert randomly pulls out a black sock is 1/5 .

Answer: x= 0
Step-by-step explanation:
- Cancel equal terms on both sides of the equation. 2 x+6 x= 392 x +6 x or 2 x = -392 x.
- move variable to the left handed side and change its sign. 2 x + 392 x = 0.
- collect like terms 394 x = 0.
- divide both sides of the equation by 394. x = 0
- and your answer is x = 0
