Answer:
A
Step-by-step explanation:
slope is (y2-y1)/(x2-x1)
anyhow that comes out to -3/2
the only place that actually applies is in A
For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!
Anyhow, all the problem is asking is to plug in the values of time to find the height.
We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.
When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.
h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.
I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!
The probability of at least one child inheriting the disease can be given by
<em>P</em>(<em>X</em> ≥ 1) = 1 - <em>P</em>(<em>X</em> = 0). This is because the only choice other than at least one child inheriting the disease is that no children get it.
Since there is a 70% or 0.7 chance that each child will inherit it, there is a 30% or 0.3 chance that they will not. This gives us
1 - <em>P</em>(<em>X</em> = 0) = 1 - (0.3)(0.3)(0.3) = 1 - 0.027 = 0.973
There is a 97.3% chance that at least one of the children will get the disease from their mother.
Answer:
The answer is B.
Step-by-step explanation:
It is saying that 647.5 calories is the total amount and 320 is a part of it. so when you do 647.5-320, it becomes 327.5 and that is c. You can only do this with the equation that letter B is saying.
