Answer:

If isomorphism exists between two groups, then the identities correspond, i.e. if f:G→G′ is an isomorphism and e,e′ are respectively the identities in G,G′, then f(e)=e′.

The graph of y=f(x) is shown below. Find the value of f (0)

meriva

Answer:

f(0) = 2

Step-by-step explanation:

Read from the graph the value "y" that the line presents when "x" is zero. That is the f(0) you are looking for.

See attached screen capture with the point highlighted

f(0) according to the image provided is equal to 2.

f(0) = 2

Approximately how much principal would need to be placed into an account earning 1.58% interest compounded monthly so that it ha

Natalija [7]

Answer:

The initial investment is $821.58

Step-by-step explanation:

Giving the following information:

Future Value (FV)= $90,597

Number of periods (n)= 25*12= 300

Interest rate (i)= 1.58% = 0.0158

<u>To calculate the initial investment, we need to use the following present value (PV) formula:</u>

PV= FV/(1+i)^n

PV= 90,597 / (1.0158^300)

PV= $821.58

The initial investment is $821.58

Answer:

The translation for the above map points is 8 units up and 5 units left.

Step-by-step explanation:

$D(7,-3)\rightarrow D'(2,5).$

The translation for the above map points is 8 units up and 5 units left.

Step 1: 8 units up

$D(7,-3)\rightarrow$ (Add 8 to y co-ordinate) $(7,-3+8)\rightarrow (7,5)$

Step 2: 5 units left

$(7,5)\rightarrow$ (subtract 5 from x-co-ordinate) $(7-5,5)\rightarrow D'(2,5)$

The Office of Student Services at UNC would like to estimate the proportion of UNC's 34,000 students who are foreign students. I

Pachacha [2.7K]

Answer:

Mean is 3.05

Standard deviation is 1.69.

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they are foreign, or they are not. This means that we can solve this problem using concepts of the binomial probability distribution.

Binomial probability distribution

The probability of x sucesses on n repeated trials, with p probability.

In this problem, we have a sample of 50 students, so $n = 50$ . The proportion of all UNC students that are foreign students is 0.061, so $p = 0.061$ .

The mean is given by the following formula:

$E(X) = np = 50*0.061 = 3.05$

The standard deviation is given by the following formula:

$\sigma = \sqrt{n*p*(1-p)} = \sqrt{50*0.061*(1-0.061))} = 1.69$
