Answer:
1. f(x) = -2x^2-12x-19
2. f(x)= 2x^2+12x+17
3. f(x)= -2x^2+12x-17
4. f(x)= 2x^2-12x+17
Step-by-step explanation:
Just took the same test. :)
Answer:
942 cubic feet
Step-by-step explanation:
First, we must solve for the radius of the sphere:
V=
r=(3
)
r=(3*
)
r≈5.99
Second, we must solve for surface area:
A=4
A=4*
*
A≈450.88
There would be 0.07923 probability to get 4 aces.
<h3>What is probability ?</h3>
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Total number of cards in deck = 52
Total number of aces = 4
When 5 cards are chosen randomly,
The probability to get 4 aces
= 1/52+1/51+1/50+1/49+0
Since, at 5th time there will be no ace remains, so probability would be 0.
= 0.01923+0.01960+0.0200+0.0204
=0.07923
