A=pi r^2
= 20.25 pi is the answer
Probability of an event =
(number of ways the event can happen) / (total number of possible outcomes) .
Well, the total number of possible outcomes is easy. It's
(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)
= 36 total possible ways for two cubes to roll.
Now, how many of those possibilities show either 4 or 7 ?
Well, here's how a 4 can come up:
1 . . . 3
2 . . . 2
3 . . . 1
and here's how a 7 can come up:
1 . . . 6
2 . . . 5
3 . . . 4
4 . . . 3
5 . . . 2
6 . . . 1 .
So there are 9 ways all together for Lenny to be successful.
The probability is (9/36) .
That's 1/4 , or 25% .
Answer:
A. -4
Step-by-step explanation:
F(-1) means we must plug the number "-1" in for each x.
F(x) = x^2 + 3x - 2
F(-1) = (-1)^2 + 3(-1) - 2
= 1 - 3 - 2
= -4
Answer: z =2.22
Step-by-step explanation:first determine the constant. Z= K(X/Y) if z is 15, x is 6 and y is 2 then 15= K(6/2) then K is 5.
When x is 4 and y is 9 . k is 5 then
Z ,= 5(4/9) = 2.2.
Hello,
y=k*x² and y=144 if x=6
==>144=k*36==>k=4
g(x)=4*x²
