Probability that the first captain's first pick is a girl = 11/21
Probability that the first captain's second pick is a girl = 12/25
<span>the probability that the first captain will pick two girls before picking any boys = 11/21 x 12/25 = 132/525 = 44/175</span>
What numbers I can't do all of them
Answer:
The average X bar would be 9.78
Take all players
Add them all together, you received 137
Then divide by the total number of players 14
147/14 = 9.79 with rounding to the second placement (100ths)
Step-by-step explanation:
Cubic Function Form:
y=
However here we only need ax^3 and +d
ax^3 makes the graph wider or skinnier or reflects it if negative.
So the first coefficient will be negative since we want to reflect it along the x axis
To move left three we will have to add 3 to the ax^3 giving us something like (x+3)^3
To move up 5 we set our y intercept (the +d part) to d=5.
Combing everything together gives us (x+3)^3+5
Answer:
(0 , 1), (4, 9).
Step-by-step explanation:
y = x2 – 2x+1
y = 2x+1
Substitute y = 2x + 1 into the first equation.
2x + 1 = x^2 - 2x + 1
x^2 - 2x - 2x = 0
x^2 - 4x = 0
x(x - 4) = 0
x = 0, 4.
When x = 0, y = 1.
When x = 4, y = 8 + 1 = 9.
