Answer:

The y-intercept and slope are wrong. In this problem, they are mixed up.

Step-by-step explanation:

In an equation like that, the y-intercept not supposed to be attached to the x. In this problem, the y-intercept point would be 4, not -3. Instead, the -3 represents the slope (rise/run).

Using the concept of margin of error, it is found that higher samples lead to more precise results, hence the correct option is:

D. it is based on a very large random sample.

The margin of error of a confidence interval is given by:

[tex]M = z\frac{s}{\sqrt{n}}[/tex]

In which:

In this problem the increase in life expectancy regarding regular slow walking should be considerably greater than 2 months, which means that the a larger sample is needed to give a more precise result, hence option D is correct.

Answer:

x = 27

Step-by-step explanation:

this problem is similar to a scale drawing where we can set up a proportion:

'x' is to 5 as 162 is to 30

x/5 = 162/30

cross-multiply:

30x = 810

x = 810/30

x = 27

Answer:

x=27

Step-by-step explanation:

( 575.75 - 65 ) / 15 = amount each player gets

your answer choice should be A

The total amount Sloan need to pay in order to get her DC license to the DMV is $935.

Total cost or the final cost is the summation of all the cost spend while buying any good or taking any service.  

Sloan went to the DMV to get a new DC License, $40.0. The state inspection requires a $50.00 fee and does not cover the costs of any mechanical issues that may need to be fixed.

Thus, the total amount Sloan paid in inspection and DC license charge is,

[tex]C=40+50\\C=90[/tex]

Now Sloan's car failed to pass inspection due to : Leaking gas caps, Imbalanced air-to-fuel ratio and faulty transmission. The total cost of repairs for the vehicle, was $875. 0.

Thus, the final cost of Sloan's car after the repairing of the vehicle is,

[tex]C=90+845\\C=935[/tex]

Thus, the total amount Sloan need to pay in order to get her DC license to the DMV is $935.

Mechanical engineer are most capable to deal with fixing a vehicle and issues related to it. Thus, a mechanical engineer required to fix Sloan's car.

Answer:

1, 2, and 3

Step-by-step explanation:

You can simplify n+2<6 by subtracting 2 from both sides to get n<4. Now you just select all options less than 4 which include 1, 2, and 3. The reason 4 is not a solution is because it is equal to, but not less than, 4. Sense 5 is greater than 4 it is not a correct answer either.

Answer:

area= 59.5    perimeter=31.6

Step-by-step explanation:

the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6

Step-by-step explanation:

Step-by-step explanation:

it is a simple addition and subtraction sequence :

10 + 0 + -21 + 14 = 3

since the result is positive, it is overall a gain.

if the result were negative, it would be an overall loss.

so, he had an overall gain of 3 yards.

Answer:

D. M and O are similar but not congruent

Step-by-step explanation:

As you can see, M and O are similar because they both have four sides and equal length for each of the side meaning that they are both squares.

At the same time, M and O are do not have the same dimensions meaning they are not congruent

Answer:

Addition and subtraction are easier than other operations like multiplication, division, square roots and to the power of.

Multiplication builds on the idea of addition, and to the power of builds on multiplication.

For example: 2+2+2=6. This is very simple, if you have 2 apples, and you get 2 more apples, and then you get 2 more apples, you add them together and you get 6 apples. Multiplication is a faster way to do this but it is more complicated. If you have 3 groups of apples, and each group has 2 apples in it, you multiply them together to get 6 apples. The reason this is faster is that instead of individually adding all the numbers together, you count the number of groups there are and multiply because you know that each group has 2 apples in it. Addition is a simple concept to understand, if you have two apples, than you add two apples more, you get 4 apples. very simple. the idea of subtraction works on a similar idea, if you have 4 apples, and you eat two, then you have 2 apples left.

If you are adding

3+3+3+3+3+3+3+3+3+3+3+3+3+3

then its very simple, right? You take 3 apples, you add 3 more apples, and you add 3 more apples...

Its very simple, but the problem is it would take forever, so you multiply instead.

How many groups do you have?

We count them all and find there are 14 groups.

14x?

What are we multiplying?

3

so 14x3=42

but we couldn't do this without simple addition because we had to add the number of groups there are.

Answer: 120000

Step-by-step explanation:

Answer:

[tex]\frac{24}{a}[/tex] - b

[tex]\frac{b-2}{a}[/tex]

[tex]\frac{21}{a}[/tex]-[tex]\frac{b}{4}[/tex]

b - [tex]\frac{2}{3}[/tex]a

25 - 2b

5b - 10a

Step-by-step explanation:

a = 3 and b = 8

Plug in a and b into your equations.

25 - 2(8) = 25 - 16..........9

[tex]\frac{8-2}{3}[/tex] = [tex]\frac{6}{3}[/tex]..........2

5(8) - 10(3) = 40 - 30..........10

[tex]\frac{24}{3}[/tex] - 8 = 8 - 8..........0

[tex]\frac{21}{3}[/tex] - [tex]\frac{8}{4}[/tex] = 7 - 2..........5

8 - [tex]\frac{2}{3}[/tex](3) = 8 - 2..........6

Then you order least to greatest.

a. Based on the AA similarity theorem, Gilligan can conclude that, ΔABC ~ ΔSDC.

b. To the nearest tenth of a foot, the distance from the ship to the shore is: 847.8 ft.

The ratios of the corresponding sides of two triangles that are similar are equal.

Two triangles with two pairs of congruent angles are similar to each other based on the AA similarity theorem.

a. In ΔABC and ΔSDC, there are two pairs of congruent angles - ∠DCS ≅ ∠BCA (vertical angles) and ∠ABC ≅ ∠SDC (right angles)

Therefore, based on the AA similarity theorem, Gilligan can conclude that, ΔABC ~ ΔSDC.

b. AB = 150 ft

Distance from the ship to the shore = SD = ?

DC = 130 ft

CB = 23 ft

Thus:

AB/SD = CB/DC

Substitute

150/SD = 23/130

SD = (150×130)/23

SD = 847.8

Thus, to the nearest tenth of a foot, the distance from the ship to the shore is: 847.8 ft.
