denise bought a life insurance policy from donald, and if denise dies, the insurance company has to pay debra, whose son is douglas. who is the beneficiary of the life insurance policy? a. donald b. debra c. denise d. douglas

Answers

The correct answer is B. Debra

Explanation:

The word "beneficiary" is used to describe the individual that receives a benefit. In the case of a life insurance policy, the receiver is always the person that receives money and other benefits when the person covered by the policy dies. This implies that in the case presented, Denise is the individual covered by the policy and the beneficiary is Debra because she will receive the money once Denise dies, and therefore she is the recipient of the benefits related to the insurance policy.

The Department of Highway Improvements, responsible for repairing a 25-mile stretch of interstate highway, wants to design a surface that will be structurally efficient. One important consideration is the volume of heavy freight traffic on the interstate. State weigh stations report that the average number of heavy-duty trailers traveling on a 25-mile segment of the interstate is 72 per hour. However, the section of highway to be repaired is located in an urban area and the department engineers believe that the volume of heavy freight traffic for this particular section is greater than the average reported for the entire interstate.
To validate this theory, the department monitors the highway for 50 1-hour periods randomly selected throughout the month. Suppose the sample mean and standard deviation of the heavy freight traffic for the 50 sampled hours are:
Sample mean = 74.1 standard deviation = 13.3
a) Do the data support the department's theory? Use α = 0.10 to come to a conclusion based on a large sample test.

Answers

Answer:

[tex]t=\frac{74.1-72}{\frac{13.3}{\sqrt{50}}}=1.116[/tex]    

The degrees of freedom are given by:

[tex]df=n-1=50-1=49[/tex]  

Now we can calculate the p value with the following probability:

[tex]p_v =P(t_{(49)}>1.116)=0.135[/tex]  

Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 72 per hour.

Step-by-step explanation:

Information provided

[tex]\bar X=74.1[/tex] represent the sample mean

[tex]s=13.1[/tex] represent the sample standard deviation

[tex]n=50[/tex] sample size  

[tex]\mu_o =72[/tex] represent the value that we want to test

[tex]\alpha=0.1[/tex] represent the significance level

t would represent the statistic

[tex]p_v[/tex] represent the p value

Hypothesis to test

We want to analyze if the true mean for this case is higher than 72, the system of hypothesis would be:  

Null hypothesis:[tex]\mu \leq 72[/tex]  

Alternative hypothesis:[tex]\mu > 72[/tex]  

The statistic is given by:

[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex]  (1)  

Replacing the info we got:

[tex]t=\frac{74.1-72}{\frac{13.3}{\sqrt{50}}}=1.116[/tex]    

The degrees of freedom are given by:

[tex]df=n-1=50-1=49[/tex]  

Now we can calculate the p value with the following probability:

[tex]p_v =P(t_{(49)}>1.116)=0.135[/tex]  

Since the p value is higher than the significance level provided of 0.1 we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly higher than 72 per hour.

Answers

Step-by-step explanation:

50÷1/2-40

50×2-40

100-40

60

the answer is 60

Answer:60

Step-by-step explanation:if the equation is 50/.5-40, the first step is to turn them into fractions 50/1 and 50/100 (or 1/2) then you flip the second fraction and change the sign to multiply so it would be 50/1x2/1.

Y=50/.5-40

Y=50/1x2/1-40

Y=100-40

That leaves you with 100/1 (or 100). Then you subtract 40 from 100

100-40=60

An element with a mass of 740 grams decays by 28.4% per minute. To the nearest minute, how long will it be until there are 30 grams of the element remaining?

Answers

Answer:t=9.6 minutes

Step-by-step explanation:

Given

mass of element is [tex]A_o=740\ gm[/tex]

Decay rate [tex]r=28.4\%\ \text{per minute}[/tex]

and we know

Amount of exponential decay is given by

[tex]A=A_o[1-r]^t[/tex]

Where [tex]A_0=\text{Initial amount}[/tex]

[tex]\text{A=Accumulated amount}[/tex]

[tex]\text{r=rate}[/tex]

[tex]\text{t=time}[/tex]

Substituting values we get

[tex]\Rightarrow 30=740[1-0.284]^t[/tex]

[tex]\Rightarrow \dfrac{30}{740}=0.716^t[/tex]

[tex]\Rightarrow 0.0405=0.716^t[/tex]

taking log both sides we get

[tex]\Rightarrow\ \ln (0.0405)=t\times \ln (0.716)[/tex]

[tex]\Rightarrow t=\dfrac{\ln (0.0405)}{\ln (0.716)}[/tex]

[tex]\Rightarrow t=9.598\approx 9.6\ \text{minutes}[/tex]

Answer: One adult ticket is $4.  One child ticket is $7

Step-by-step explanation:

Day 1:

2a + 10c = 78

Day 2:

8a + 5c = 67

2a + 10c = 78

8a + 5c = 67

Multiply Day 2 by 2 so we get the 'c' equal so we can subtract them:

Day 2: 16a + 10c = 134

Day 1: 2a + 10c = 78

Minus Day 2 from Day 1

= 14a = 56

56 / 14 = 4

So A = 4

Now substitute 4 for A in Day 1

2(4) + 10c = 78

8 + 10c = 78

10c = 78 - 8

10c = 70

c = 70 / 10

c = 7

What is Surface Area?

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given two rectangular containers.

We have to find the surface area of both the containers.

Surface area of a rectangular prism = 2[(l × w) + (w × h) + (l × h)]

Here l, w and h are the length, width and height of the rectangular prism.

For the first rectangular prism,

Surface area = 2 [(5 × 4) + (4 × 7) + (5 × 7)] = 166 cm²

For the second rectangular prism,

Surface area = 2 [(4 × 3) + (3 × 10) + (4 × 10)] = 164 cm²

Hence the container on the right is made of 2 centimeters squared more plastic.

There is a bag filled with 3 blue, 4 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of exactly 1 red?

Answers

Answer:

22.22%

Step-by-step explanation:

If it is exactly a red, it means that it is removed on the first or second attempt, but only once, in this case it does not matter if it is on the first or second attempt because the marble is returned to the bag.

So suppose that on the first attempt red is drawn, the probability would be:

4 / (3 + 4 + 5) = 4/12 = 1/3

Now, on the second attempt, it is not to draw a red, it must be green or blue, so it would be:

(5 + 3) / (3 + 4 + 5) = 8/12 = 2/3

The final probability then is:

1/3 * 2/3 = 0.2222

that is, the probability is 22.22%

porch in 11 minutes. If they worked
together how long would it take them?​

Answers

Answer:

It will take them 6.35 minutes

Step-by-step explanation:

The question can be solved when you know how much of the job can be done in minutes.

Therefore if Dan can do the job in 15 minutes he will be to sweep 1/15 of the porch in 1 minutes. Alberto can do the same job in 11 minutes, in 1 minutes he will do 1/11 of the job.

let

a = combined time together

1/15 + 1/11 = 1/a

(11 + 15)/165 = 1/a

26/165 = 1/a

cross multiply

26a = 165

divide both sides by 26

a = 165/26

a = 6.34615384615

a ≈ 6.35 minutes

if Carlos has 42 books he wants to store on shelves. Each book is
1 3/4 inches thick. He can buy 3-foot-long shelves for $27.99 each.
How much will it cost to shelve the books?

Answers

Answer:

$83.97

Step-by-step explanation:

Let's find the total thickness of all 42 books first. To do this, we do 42 * 1.75 = 73.5 inches. We know that each shelf is 3 feet long, but we want to convert to the same unit so that it's easier to calculate, so each shelf is 3 * 12 = 36 inches long. Now, to find the number of shelves needed, we'll do total thickness/length of each shelf which is 73.5 / 36, or 2.04. Our answer has to be an integer (because you can't have half of a shelf), so do we round up or down? Well, if we rounded down, then there wouldn't be enough room for all the books, so we round up to 3 shelves instead. Because each shelf is $27.99, the price for 3 will be 27.99 * 3 = $83.97. Hope this helps!

I think the answer is $83.97 hope you get it right
