You just find the quartiles which are 62 and 50 the mines them which equals 12.
F(-1) = 2(-1)^2 + 8(-1)
= 2(1) + (-8)
= -6
0.27 cents. Just divide 3.78 by 14 to find the unit price.
There are a total of 8 balls
The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4
Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14
Answer:
5x<x^2-24
Step-by-step explanation:
pretty sure that's right and the x^2 that's an exponent :)
