What are fractions?
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. In ordinary English, a fraction refers to the number of parts of a specific size.
We are given,
1.
As the denominator of both fractions are same we add the numerator
We get,
2.
As the denominator of both the fractions are same we subtract the value in the numerator we get,
3.
We first simplify the first term of the equation,
Now as the denominator is not same we use cross multiplication to perform the operation
On further simplifying we get,
Hence the answers are
1. 1
2.
3.

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
The value of function on x=1 is 0.5
Step-by-step explanation:
In order to find the value of a function on given input, the input is put at the place of variable in the function.
Given function is:
We have to find the value of function on x = 1
Putting x = 1 in function
Hence,
The value of function on x=1 is 0.5
