Check the explanation
Step-by-step explanation:
where the letter D is the diagonal matrix with diagonal entries λ1,…,λn. Now let's assume V is invertible, that is, this particular given eigenvectors are linearly independent, you get M=VDV−1.
Kindly check the attached image below to see the step by step explanation to the question above.
b. 1.3
c. 2
d. 3
Answer: a. 1
Step-by-step explanation:
Given : Population mean :
Standard deviation :
Let n be the number of times a beach ball with a diameter of 26.7 cm differ from the mean.
Then, we have
Hence, a beach ball with a diameter of 26.7 cm is 1 standard deviation differ from the mean.
Answer:
It will take them approximately 51.43 minutes to complete the project together
Step-by-step explanation:
This is what is called a "shared job" problem.
The best way to work on them is to start by finding the "portion" of the job done by each of the people in the unit of time.
So, for example, Sarah completes the project in 90 minutes, so in the unit of time (that is 1 minute) she completed 1/90 of the total project
Betty completes the project in 120 minutes, so in the unit of time (1 minute) she completes 1/120 of the total project.
We don't know how long it would take for them to complete the project when working together, so we call that time "x" (our unknown).
Now, when they work together completing the entire job in x minutes, in the unit of time they would have done 1/x of the total project.
In the unite of time, the fraction of the job done together (1/x) should equal the fraction of the job done by Sarah (1/90) plus the fraction of the job done by Betty. This in mathematical form becomes:
So it will take them approximately 51.43 minutes to complete the project together.
Answer:
Step-by-step explanation:
Data given and notation
n=250 represent the random sample taken
estimated proportion of readers owned a particular make of car
is the value that we want to test
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that that the percentage is actually different from the reported percentage.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion is significantly different from a hypothesized value .
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
What is the total?
What is the percent?
What is the answer?
Answer:
80 percent of 16 is 12.8 I'm sorry but that's all I know
40 POINTS
The coordinates of point C are (1, 24/5).
We are given that;
Point A(−2, 6) and point B(3, 4)
Now,
The shortest distance (length of the straight line segment's length connecting both given points) between points (p,q) and (x,y) is:
Let’s first find the distance between A and B using the distance formula:
AB =
Now find the coordinates of point C. Since AC:CB is 2:3, we can write:
AC/CB = 2/3
AC = (2/5) * AB
CB = (3/5) * AB
Let assume that point C has coordinates (x, y). Then we can write:
x = (3/5)3 + (2/5)(-2) = 9/5 - 4/5 = 1
y = (3/5)*4 + (2/5)*6 = 12/5 + 12/5 = 24/5
Therefore, by the distance answer will be (1, 24/5).
