Someone please help!!!!! WILL MARK BRAINLIEST

Answer:

y = (1/2)x + 1

Step-by-step explanation:

linear line equation is y = mx + b

Where m is the slope and b is the y-intercept when x is 0.

For m, m is change in y(delta y) over change in x(delta x).

We are given two points: (0,1) and (4,3).

m = (y2 - y1)/(x2 - x1) = (3-1)/(4-0) = 2/4 = 1/2

y = (1/2)x + b

Now plug in (0,1) into above equation to find b value.

1 = (1/2)0 + b => b = 1

Final equation is y = (1/2)x + 1

1. A random sample of 2,000 households are selected for telephone interviews with the following results: 432 Completed interview

fenix001 [56]

The response rate is 52.021%.

Given a random sample of 2,000 households are selected for telephone interviews in which 432 interviews are completed, 586 are refused by the respondent, 902 do not answer or are not at home and 80 are non-working numbers.

Total Number of sample, S =2000

Completed interview, C = 432

Refusal by the Respondent, R = 586

No answer/ not at home , N = 902.

Non - working Numbers, NW = 80.

From the above data, we got responses from completed interviews and refusals by respondents.

so responded number (RN) is

RN=C+R

RN= 432+ 586

RN= 1018.

The actual number of samples =Total samples - non-working samples Actual number of samples=2000-80

The actual number of samples=1920

And the response rate (RR) is

RR=1018÷1920

RR=0.52021

Hence, the response rate from 2000 households which are selected for telephone interviews is 0.52021.

Answer:

m= 5

Step-by-step explanation:

-7m-5(m+5)= -85

-7m-5m-25= -85

-12m-25= -85

-12m= -60

/-12 /-12

Melanie is looking for a loan. She is willing to pay no more than an effective rate of 9.955% annually. Which, if any, of the fo

lakkis [162]

Answer:

c) A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual

Step-by-step explanation:

Hi, well, let´s transform all this nominal rates into effective annual rates.

Loan A: 9.265% nominal rate, compounded weekly

In order to find the easiest effective rate, we need to divide this rate by 52 (which are the weeks in a year). Once we do that, we convert this effective weekly rate into an effective annual rate. Let´s walk you through all this.

$r(E.week)=\frac{0.09265}{52} =0.00178173$

Or 0.178173% effective weekly. Now we can transform it into an effective annual rate.

$r(e.a)=(1+r(e.week))^{52} -1$

$r(e.a)=(1+0.00178173)^{52} -1=0.09699$

Or 9.669% annual, which is less than 9.955%, so this one is sellected, let´s check the next.

Loan B: 9.442% nominal rate, compounded monthly

Just like we did with Loan A, we need to divide this rate too, only this time, we will divide by 12, therefore obtaining an effective monthly rate.

$r(E.month)=\frac{0.09442}{12} =0.00786833$

Or 0.786833% effective monthly, let´s turn it into a effective annual rate.

$r(e.a)=(1+r(e.month))^{12} -1$

$r(e.a)=(1+0.00786833)^{12} -1=0.09862$

Or 9.862% annual, so this rate would work for Melanie too. This means that option C) is the answer we are looking for but, let´s walk that extra mile and turn that Loan C rate into an annual rate.

$r(E.quarter)=\frac{0.09719}{4}=0.0242975$

or 2.42975% effective quarterly, now, let´s convert it into an effective annual rate.

$r(e.a)=(1+0.0242975)^{12} -1=0.10079$

That is 10.079% effective annual, therefore, Loan C is not an option for Melanie.

Best of Luck.
