A civil engineer wants to know the opinions of drivers about online driving tests. She obtains a list of 730 drivers who have recently completed an online driving course and e-mails a questionnaire to a randomly selected group of 200 of these drivers. Only 102 of the questionnaires are returned. Identify the population and the sample in this study. (4 points)

The population is 200 and the sample is 102.
The population is 730 and the sample is 200.
The population is 102 and the sample is 730.
The population is 730 and the sample is 102.
The population is 200 and the sample is 730.

Answers

Answer 1

Answer: The population is 730 and the sample is 102.

Step-by-step explanation:

When we have a given set of elements, N elements, the population is N.

And if we do statistics with A of these N elements, the sample is A.

In this case, the population is the set of the 730 drivers, then the population is 730.

And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).

Then the sample will be 102.

Then the correct option is:

The population is 730 and the sample is 102.

Answer 2

Answer:

730 and 102.

An angle measures 40 more than the measure of its supplementary angle. What is the measure of each angle

Answers

Sum of two angles that are supplementary = 180°

Let the first angle be x .

Then the other angle = x + 40

Measure of each angle =

[tex]x + x + 40 = 180[/tex]

[tex]2x + 40 = 180[/tex]

[tex]2x = 180 - 40[/tex]

[tex]2x = 140°[/tex]

[tex]x = \frac{140}{2} [/tex]

[tex]x = 70°[/tex]

Which means :-

The first angle:-

[tex]= x = 70°[/tex]

The second angle :-

[tex]x + 40[/tex]

[tex]70 + 40[/tex]

[tex] = 110°[/tex]

Therefore , the two supplementary angles are 70° and 110° .

What is the slope intercept for the line below?

Answers

to find the slope from two points, use the equation m = (y2-y1)/(x2-x1)

substitute
m = 4-2/5-0 = 2/5
the slope is 2/5

the line intercepts the y axis at (0,2), so the y intercept (b) is 2

slope intercept form: y = mx + b

so the slope intercept equation for the line is:
y = 2/5x + 2

Actually Welcome to the Concept of the Compound Interest.

Since we know that formula for the Compound interest is :-

A= P(1+r/n) ^nt

here, A = total amount received at end, P= initial amount invested, r= rate of interest in decimal, t= time of years and n= frequency per year, so we get as,

=>10110.28 = P(1+0.035/2)^2*5

=>10110.28 = P (1+0.0175)^10

=>10110.28= P(1.0175)^10

=>so finally we get as

=>P= 1011.28/1.1894

=> P= 8500

Using Concept of the Compound Interest, the amount of the original investment was $8500.

What is Compound interest?

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest =A= P(1+r/n) ^nt

Where, A = total amount received at end, P= initial amount invested, r= rate of interest in decimal, t= time of years and n= frequency per year,

Therefore, we get as,

10110.28 = P(1+0.035/2)^2 x 5

10110.28 = P (1+0.0175)^10

10110.28= P(1.0175)^10

so finally we get as;

P= 1011.28/1.1894

P= 8500

Using Concept of the Compound Interest, the amount of the original investment was $8500.

Points $A$ and $B$ have the same $y$-coordinate of 13, but different $x$-coordinates. What is the sum of the slope and the $y$-intercept of the line containing both points?

Answers

Answer:

13

Step-by-step explanation:

This one sounds really hard, but its actually really easy once you think about it.

The problem states that both y coordinate are 13, but have different x coordinates. It asks for the sum of the slope and the y intercept. The y intercept will always have 0 as x.

To find a slope, the equation is y2-y1/x2-x1. In this case, we don't actually know what x is. But we do know what y is:

13-13/x2-x1

0/x2-x1

0

So the slope is 0.

Since we know that the y intercept has to have 0 as x, we don't actually need to know what x is.  

So the y intercept is 13.

13+0=13.

Answers

So the parent function is y=x, right? y=-2x+6 is different because the slope is -2 (which flips the line so it's now going from left to right while also being more "taller", and the line's y-intercept is 6, while on the parent function, the y-intercept is 0.

Parent function: y = x (or y=mx+b)

Your function: y = -2x+6

6 = y-intercept (b)

-2 = slope (m)

Once upon a time a farmer went to a market and purchased a wolf, a goat, and a

cabbage. On his way home, the farmer came to the bank of a river and rented a

boat. But crossing the river by boat, the farmer could carry only himself and a

single one of his purchases: the wolf, the goat, or the cabbage.If left unattended

together, the wolf would eat the goat, or the goat would eat the cabbage.The

farmer's challenge was to carry himself and his purchases to the far bank of the

river, leaving each purchase intact. How did he do it?

Answers

Given that the wolf would eat the goat, the goat would eat the cabbage but the wolf wouldn't eat the cabbage.

So, leave the wolf and cabbage behind (at side 1) and take the goat to the other side (side 2) of the river.

Then, come back with the empty boat from side 2 to side 1.

Take the wolf (or the cabbage) from side 1 to side 2 of the river.

Now, observe that, the goat is already on side 2, and the wolf and the goat can't be on the same side as the wolf would eat the goat, So, leave the wolf on side 2 and come back with the goat from side 2 to side 1.

Leave the goat on side 1 and take the cabbage from side 1 to side 2.

Now, come back with the empty boat from side 2 to side 1 and take the goat from side 1 to side 2.

In this way, the farmer can carry himself and his purchase to the other side of the river.
