Answer:
p=0.063
Step-by-step explanation:
Let X be number of the certain brand of jelly beans that are made so that each package contains about the same number of beans.
X is N(375, 8)
YOu are collecting a sample size of
n = 8
Findings from the sample


(Left tailed test at 5% level)
Since sample size is small though sigma is known we use Z test, since norm
Mean difference = -5
Std error = 
Test statistic t = mean diference / std error = 
df = n-1 =5
p value = 0.063
Answer:
4 cm
Step-by-step explanation:

Answer:
Step-by-step explanation: I did a formula to get the answer
2x-10=5x-100
2x=5x-90
I subtracted 100-10 and then got 90
3x=90
3x/3x=90/3
x=30
Answer:
The result of the integral is:

Step-by-step explanation:
We are given the following integral:

Trigonometric substitution:
We have the term in the following format:
, in which a = 3.
In this case, the substitution is given by:

So

In this question:



So

We have the following trigonometric identity:

So

Replacing into the integral:

Coming back to x:
We have that:

So

Applying the arcsine(inverse sine) function to both sides, we get that:

The result of the integral is:
