The probability of getting grey: 2/10
The probability of getting blue: 8/10
The probability of getting blue then grey:
8/10 x 2/10
Answer 4/5
Answer:
x= -5
y= -2
Step-by-step explanation:
From the equation y=x+3-------eqn 1
x+y= -7-------eqn2
x+(x+3)= -7 (since there is no value before the bracket is 1, so multiply by 1)
x+x+3= -7
2x+3=-7
2x=-7-3
2x=-10
x=-10/2
x=-5
Insert x value in equation 1
y= -5+3
y=-2
Answer:
Bob could predict a <u>100%</u>, as if he has studied for a long time, and has learnt the content, he should be able to get 100%!
The bag contains,
Red (R) marbles is 9, Green (G) marbles is 7 and Blue (B) marbles is 4,
Total marbles (possible outcome) is,
Let P(R) represent the probablity of picking a red marble,
P(G) represent the probability of picking a green marble and,
P(B) represent the probability of picking a blue marble.
Probability , P, is,
Probablity of drawing a Red marble (R) and then a blue marble (B) without being replaced,
That means once a marble is drawn, the total marbles (possible outcome) reduces as well,
Hence, the best option is G.
Answer:
x^2 - 10 = (p - 9)(x)
Step-by-step explanation:
Please indicate exponentiation with the symbol " ^ ": p(x) = x^2 - 1.
To obtain (p - 9), start with p(x) = x^2 - 1 and subtract 9:
(p - 9)(x) = x^2 - 1 - 9 = x^2 - 10 = (p - 9)(x)
