Answer:
1.861
Step-by-step explanation:
I just know
199.
the z score for the 90th percentile is 1.28, so you can solve the equation
which gets you the 199
The first machine does 200 in 1 hour, so in 8.5 hours it will then do 200 * 8.5.
the second machine does 180 in 1 hour, so in 8.5 hours it will then do 180 * 8.5.
the third machine does 150 in 1 hour, so in 8.5 hours it will do then 150 * 8.5.
how many bottles will they all do in total on that time?
(200 * 8.5) + (180 * 8.5) + (150 * 8.5)
Answer:
80%
Step-by-step explanation:
from $25 to $45
$45/$25 = 1.8
$25 x 1.8 = $45
therefore, the increase is 80%
Since P(<em>X</em> = <em>x</em>) = 0.3 for all 0 ≤ <em>x</em> ≤ <em>α</em>, we have
So,
