Cos(68)=z/24
Z=24cos(68)
Find the answer by the calculator
Second question,
Cos(x)=16/34
X=cos^-1(16/34)
Use calculator
x=4
Step-by-step explanation:
2x+4=12
-4 -4
---------------
2x = 8
---- ---
2 2
x=4
Simple...
if f(x)= -5x-4 and g(x)=6x-7
And you want f(x)+g(x)
then just add.....f(x)+g(x)
-5x-4+6x-7
1x-11
This is the answer to f(x)+g(x)=1x-11
Thus, your answer.
Answer:
a) 38.4% probability that on a given day this item is requested more than 5 times.
b) 0.67% probability that on a given day this item is not requested at all.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
An inventory study determines that, on average, demands for a particular item at a warehouse are made 5 times per day.
This means that 
What is the probability that on a given day this item is requested
(a) more than 5 times?
Either it is requested 5 times or less, or it is requested more than 5 times. The sum of the probabilities of these events is decimal 1. So

We want P(X > 5). So

In which










38.4% probability that on a given day this item is requested more than 5 times.
(b) not at all?

0.67% probability that on a given day this item is not requested at all.
Answer:
75.03
Step-by-step explanation:
14×11×sin(77)
= 75.02649499..
≈ 75.03 (rounded to nearest hundredth)
