The following represent matrices and the dimension of each is also stated below. A is a matrix of size 4X2 B is a matrix of size 3X5 C is a matrix of size 7X2 D is a matrix of size 5X4 E is a matrix of size 5X3.
Which of the following matrices products are defined?
Answer:
EB is defined
BE is defined
BD is defined
and DA is defined
Step-by-step explanation:
To know that the product of two matrices are defined, the column of the first matrix must be the same as the row of the second matrix.
For example; for EB we have 5 columns for E and 5 rows for B. After this product is done it produces a matrix with dimension 3 x 3, which means 3 by 3 (3 rows by 3 columns)
to the nearest tenth.

The p-value for the given test is 0.0901.
Given that, a pharmaceutical manufacturer is concerned that the impurity concentration in pills should not exceed 3%.
What is a standard deviation?
Standard deviation is the degree of dispersion or the scatter of the data points relative to its mean, in descriptive statistics.
Given, Mean = 3.07, μ=3%, σ =0.4% and n=64.
Hypothesis test ;μ=3 and
;μ>3
We need to test the null hypothesis against the alternative hypothesis, we reject the null hypothesis and accept the alternative hypothesis.
When x>x critical
x critical = μ+Z+σ
Z = (x-μ)/(σ/√n)
= (3.07-3)/(0.4/√64)
= (0.07)/0.05
= 1.4
α = 5 and = 1.645
If Z>
1.4 > 1.645
Therefore, we do not reject null hypothesis at 5% significant level.
There is sufficient evidence that the mean impurity in concentration pills is 3% or less than 3%.
p-value
p−value=P(Z>1.4)
=1−P(Z<1.4)
=1−0.90988
=0.0901
Therefore, the p-value for the given test is 0.0901.

Answer:
Part 1= Pi * R Squared
Part 2: 50.27
Part 3: 78.54
Part 4: 28.27
Step-by-step explanation:
Part 1: Memorize the formula
Part 2: 8 feet diameter = Pi * 4 squared. 8 feet is the diameter so the radius is 4. 4 squared is 16. 16 * pi = approximately 50.27, but is 50.24 if 3.14 is used as pi.
Part 3: Pi * 5 squared since 10 is diameter. 25 * pi which is close to 78.54, but is 78.5 is 3.14 is used for pi.
Part 4: I subtracted Part 3 from Part 2.
