Answer:
A
Step-by-step explanation:
Machine A pops more popcorn (12.75 vs 10 oz) in less time (3 min vs 4 min), so pops popcorn the fastest.
Machine A pops more popcorn in one minute, on average.
_____
<em>Additional comment</em>
As a practical matter, neither machine may have popped <em>any</em> popcorn in one minute. Generally, one must wait for the cycle to complete. The average overall rate will depend on how quickly each machine can be recycled to produce another batch.
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958
Given:
The vertices of triangle FGH are F(-2,1), G(1,3) and H(0,5).
To find:
The vertices of F'G'H' for a reflection over the y-axis.
Solution:
If a figure is reflected over the y-axis, then
![(x,y)\to (-x,y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%28-x%2Cy%29)
Using this rule of reflection, we get
![F(-2,1)\to F'(-(-2),1)](https://tex.z-dn.net/?f=F%28-2%2C1%29%5Cto%20F%27%28-%28-2%29%2C1%29)
![F(-2,1)\to F'(2,1)](https://tex.z-dn.net/?f=F%28-2%2C1%29%5Cto%20F%27%282%2C1%29)
Similarly,
![G(1,3)\to G'(-1,3)](https://tex.z-dn.net/?f=G%281%2C3%29%5Cto%20G%27%28-1%2C3%29)
![H(0,5)\to H'(0,5)](https://tex.z-dn.net/?f=H%280%2C5%29%5Cto%20H%27%280%2C5%29)
The vertices of F'G'H' are F'(2,1),G'(-1,3), H'(0,5). Therefore, the correct option is B.
