A study was conducted on the effects of long-term marriage (more than 10 years). Researchers gathered data from a random sample of 4,563 adults and measured quite a few variables, in addition to the explanatory variable of marriage and the response variable of longer life span. According to a newspaper article summarizing the study, those in long-term marriages were more likely to be more physically active, at a healthy weight, and nonsmokers. Those who were not married were about 20% more likely to be deceased. What conclusion can we draw from this study? Explain.

We can infer a cause-and-effect relationship because the sample was selected randomly.

We cannot infer a cause-and-effect relationship because treatments were not assigned randomly.

We cannot infer a cause-and-effect relationship because we do not have a control group.

We can infer a cause-and-effect relationship because multiple variables were included.

We cannot infer a cause-and-effect relationship because the treatments imposed were not blocked correctly.

Answers

Answer 1

Answer:

The correct option is;

We cannot infer a cause and effect relationship because the multiple variables were included

Step-by-step explanation:

The criteria required in order to establish a cause and effect relationship includes the following;

1) There must be a temporal precedence between the cause and the effect such that the cause must take place before the effect

In the question, it is not clearly stated weather there was a divorce (the likely cause) takes place before the event

2) In the vent that the cause occurs, the effect must occur

Therefore, all those who are not married are expected to be deceased for there to be a cause and effect relationship

3) The cause and effect relationship must not be explicable by other factors

In the question, it is stated that those who were married were more likely to be active physically, maintain an healthy weight and were nonsmokers, which are factors that contribute to longevity.

A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send to her customers. Each of the flower pots weighs 1 lb. and 12 oz. The packing material weighs 5 oz. Will her package be labeled as "heavy"?

Answers

Answer:

No, the package will not be labeled "heavy"

Step-by-step explanation:

1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).

2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.

3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.

4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.

Final) so in the end, you would have 10lb. 13oz.

» Which expression shows 35 + 15 written as a product of two factors?

Answers

Answer:

[tex]35 + 15 = 5 * 10[/tex]

The factors are 5 and 10

Step-by-step explanation:

Given

[tex]35 + 15[/tex]

Required

Express as a product of two factors

[tex]35 + 15[/tex]

Start by factorizing the expression:

[tex]5(7 + 3)[/tex]

Add the expression in the bracket

[tex]5(10)[/tex]

Replace bracket with *

[tex]5 * 10[/tex]

Hence:

[tex]35 + 15 = 5 * 10[/tex]

The expression which shows 35 + 15 written as a product of two factors is 5(7 + 3).

What is meant by expression?

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.

A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.

Let the expression be 35 + 15

Express as a product of two factors

35 + 15

Factorizing the expression we get

5(7 + 3)

simplifying the above expression, we get

5 (10)

Hence:

35 + 15 = 5 × 10

Therefore, the correct answer is option b) 5(7 + 3).

The complete question is:

Which expression shows 35 + 15 written as a product of two factors?

a) 5(6 + 3)

b) 5(7 + 3)

c) 7(5 + 2)

d) 7(5 + 3)

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.

Answers

Answer:

$434.16346

Step-by-step explanation:

Given that :

Gross earning= $14500

Federal, state and local taxes = 11%

0.11 * $14500 = $1595

FICA tax rate = 7.65%

0.0765 * 14500 = $1109.25

Personal deduction :

3.5% * 14500

0.035 * 14500 = $507.50

Total deduction :

$(1595 + 1109.25 + 507.50)

= $3211.75

Net earning : $(14500 - 3211.75) = 11288.25

Since she is paid bi weekly:

Number of biweeks in a year = 52 /2 = 26

Number of payments per annum = 26

Hence,

Net pay per period :

11288.25 / 26

= $434.16346

5. The length of a rectangle is 3 inches less than its width. If the
perimeter is 74 inches, find the dimensions of the rectangle.

Answers

Answer:

length is 17 in, width is 20

Step-by-step explanation:

let's shape this as an algebraic equation, where x= the length of one side.

since the width is 3 inches longer than the length, x will be the length and x+3 will be the width.

the perimeter is 74 in, and the perimeter is the added length of all sides. in a rectangle, 2 sides are the length and 2 sides are the width, so:

74 = 2x + 2(x + 3)

let's distribute the 2.

74 = 2x + 2x + 6

now, we combine the x's.

74 = 4x + 6

after this step, subtract 6 from the right to add it to the left side.

68 = 4x

finally, divide both sides by 4.

17 = x

perfect! now that we know the length, we just have to add 3 to find the width.

17 + 3 = 20

how do i find angle 1 without angle 2 and only the 70?

Answers

Angle 1 is vertical to 60° meaning that angle 1 is equal to 60°.

All triangles’ angles always add to 180 degrees. Since angle 1 is across from the angle measuring 60 degrees, angle 1 will measure 60 degrees. To find angle 2, you can add 70 and 60, which is equal to 130, and subtract 130 from 180. In other words. Angle 1 would measure 60 degrees and angle 2 would measure 50 degrees. To find angle 3 you can add 60+40=100 and subtract that from 180: 180-100=80 degrees. Hope that helped!

The medians of ADEF are DK, EL, and FJ. They meet at a single point M.
(In other words, M is the centroid of ADEF.)
Suppose ML = 9, MJ=8, and DK = 24.
Find the following lengths.
Note that the figure is not drawn to scale.

Answers

Answer:

FJ = 24

DM = 16

EM = 18

Step-by-step explanation:

I remember that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side. Therefore the median is split into two parts where one side is always twice as long as the other. So given that segment ML is 8, the other part of the segment (DM) must be 16 as 16 is 2/3 of 24 and 8 is 1/3 of 24 and 1/3 + 2/3 = 1.

Therefore, since MJ is 8, FM must be twice as long so it is 16. Add them up to get FJ, and 8 + 16 is 24.

Finally for EM, since the longer part of the median is twice the length of the smaller part EM must be 18 since 9 × 2 = 18, and 2/3 of 18 is 27, 9 + 18 = 27.

A. 17671.5 ft^3
B. 24740 ft 3
C. 15557 8 ft3

Answers

The calculated value of the volume of the grain bin is (a) 17671.5

Calculating the volume of the grain bin

From the question, we have the following parameters that can be used in our computation:

Composite figure = Cone and Cylinder

The volume of the grain bin is calculated as

Volume = Cone + Cylinder

Using the volume formulas of the shapes as a guide, we have the following:

Volume = 1/3 * 3.14 * (30/2)² * (35 - 20) + 3.14 * (30/2)² * 20

Evaluate

Volume = 17662.5

Hence, the volume of the grain bin is (a) 17671.5
