Vigorous exercise helps people live several years longer (on average). Whether mild activities like slow walking extend life is not clear. Suppose that the added life expectancy from regular slow walking is just 2 months. A statistical test is more likely to find a significant increase in mean life expectancy if:_______.
A. respondents tell the truth about exercising.
B. the size of the sample doesn't have any effect on the significance of the test.
C. 95% confidence is high enough.
D. it is based on a very large random sample.
E. it is based on a very small random sample.
Hint:Think about the importance of the sample size.
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.
What is the margin of error of a confidence interval?The margin of error of a confidence interval is given by:
[tex]M = z\frac{s}{\sqrt{n}}[/tex]
In which:
z is the critical valuer related to the confidence value, the higher the confidence level the higher z.s is the standard deviation.n is the sample size.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.

Sloan went to the DMV to get a new DC License $40. 0. When she got there, the clerk told her she needed a state inspection. The state inspection requires a $50. 00 fee and does not cover the costs of any mechanical issues that may need to be fixed. Once the inspection was completed, Sloan was told that her 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. HOW MUCH, IN TOTAL, WOULD SLOAN BE PAYING TO GET HER DC LICENSE? WHAT TYPE OF ENGINEER WOULD BE ABLE TO FIX SLOAN'S CAR?.
The total amount Sloan need to pay in order to get her DC license to the DMV is $935.
What is the total cost?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:
37.69 (≈ 38 ft²)
Step-by-step explanation:
2πr = 30.77
r = 30.77 / (2 * 3.14) = 4.9
half of free-throw circle area: πr² / 2 = (3.14 * 4.9²) / 2 = 37.69 (≈ 38 ft²)

Figure N has four sides that measure 2 units each. Figure O has four sides that measure 4 units each. Which of the following statements is true about the three quadrilaterals? (4 points) a M and O are similar and congruent. b O and N are similar and congruent. c M and N are similar but not congruent. d M and O are similar but not congruent.
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:
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

Reason why addition and subtraction should be taught first
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.
I hope this helps!

Gilligan sees a ship coming close to the shore he’s standing on.
he wants to determine the distance (segment SD) from the ship to the shore.
he walks 130ft along the shore from point D to point C and marks the spot.
then he walks 23ft further and marks point B.
he turns 90° and walks until his location (point A), point C, and point S are collinear.
Answer the following questions making sure to show all your work.
(A) can Gilligan conclude that triangle ABC and triangle SDC are similar? why or why not?
(B) suppose AB = 150ft. what is the distance from the ship to the shore? show all your work and round your final answer to the nearest tenth of a foot.
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.
What are Similar Triangles?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.

Which values from set 1,2,3,4,5 make the inequality true n + 2 < 6
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.
