Answer:
The answer for standard deviation would be:
4.382
Answer:
48
Step-by-step explanation:
Signals during a multiplication of two numbers:
They have the same signal: The multiplication is positive.
They have different signals: The multiplication is negative.
3 times (-8) times (-2)
First 3*(-8):
Different signals, so negative. 3*8 = 24. So the answer is -24.
Then:
3*(-8)*(-2) = (-24)*(-2)
Same signal, so positive. 24*2 = 48. The answer is 48.
Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.
8=12-8x
-4=8x
-4÷8=8x÷8
-0.5=x
