If the stack is 21ins and each board is 1 3/2 ins thick that means you 21/(1 3/2) so you end up getting 8.4. Because you can't have a part of a board you round the number down to 8 boards.
Answer:
16 ft/s²
Step-by-step explanation:
s(t) = sin(t) - 4cos(2t)
Differentiation for v
v(t) = cos(t) + 8sin(2t)
Differentiate for a
a(t) = -sin(t) + 16cos(2t)
At t = π
a(π) = -sin(π) + 16cos(2π)
= 0 + 16
= 16
I'm sorry can you type it out? I can't see it very well
Answer:
Probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.
Step-by-step explanation:
We are given that the diameters of ball bearings are distributed normally. The mean diameter is 106 millimeters and the standard deviation is 4 millimeters.
<em>Firstly, Let X = diameters of ball bearings</em>
The z score probability distribution for is given by;
Z =
~ N(0,1)
where,
= mean diameter = 106 millimeters
= standard deviation = 4 millimeter
Probability that the diameter of a selected bearing is greater than 111 millimeters is given by = P(X > 111 millimeters)
P(X > 111) = P(
>
) = P(Z > 1.25) = 1 - P(Z
1.25)
= 1 - 0.89435 = 0.1056
Therefore, probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.
Answer:
f(x)= 3, g(x)=8
Step-by-step explanation:
if you plug 3 into the equation 2x-3, you have 6-3, which is 3.
If you plug 3 into the equation 3x-1, you have 9-1, which is 8
