Step-by-step explanation:
Answer:
the probability that the ext order will be shrimp = 27.78%
Step-by-step explanation:
Vegetable 333
Chicken 666
Pork 222
Beef 222
Shrimp 555
total = 1,998
P (shrimp) = 555 / 1,998 = 0.2777 or 27.78%
in case the numbers in the orders were:
Vegetable 3
Chicken 6
Pork 2
Beef 2
Shrimp 5
total = 18
P (shrimp) = 5 / 18 = 0.2777 or 27.78%
The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.
Answer:
Step-by-step explanation:
a = number of successful events
b = total number of events.
Using the product rule, which states that (uv)' = u'v + uv':
If y = (e^-2x)(sec3x)
y' = (e^-2x)'(sec3x) + (e^-2x)(sec3x)'
y' = -2(e^-2x)(sec3x) + (e^-2x)(3 sec3x tan3x)
y' = 3(e^-2x)(sec3x tan3x) -2e^-2x (sec3x)
This matches choice B.
