Based on information from a large insurance company, 68% of all damage liability claims are made by single people under the age of 25. A random sample of 53 claims showed that 41 were made by single people under the age of 25. Does this indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company

Answers

Answer 1

Answer:

No, it doesn't indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company

Step-by-step explanation:

Let's first state the hypotheses.

Null hypothesis; H0: p = 0.68

Alternative hypothesis; Ha: p > 0.68

A random sample of 53 claims showed that 41 were made by single people under the age of 25.

Thus; p^ = 41/53 = 0.7736

Let's find the test statistic from the formula;

z = (p^ - p_o)/√(p_o(1 - p_o)/n)

z = (0.7736 - 0.68)/√(0.68(1 - 0.68)/41)

z = 0.0936/0.07285

z = 1.28

From online p-value from z-score calculator, using z = 1.28, one tail hypothesis and significance level of 0.05,we have;

P(z > 1.28) = 0.100273

The p-value gotten is greater than the significance value and so we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim.

Part B: Write an equation that can be used to find the value of the piano, v, after t years

Answers

Answer:

Part A would be: 3, $2560 & 4, 2048 I am pretty sure

Step-by-step explanation:

20% of 3,200 = 640

3,200-640= 2,560

then

20% of 2,560 = 512

2,560-512 = 2,048

hope this helps! :)

Part A: The first answer is correct, or (3, $2560) & (4, $2048)

Part B: V = 5,000(0.8)^t

5000 is the original price, 0.8 shows the value going down 20%, and t shows how many years.

Answers

ANSWER: 28 days

EXPLANATION

there are 7 days in a week. To find out how many days in 4 weeks multiply the number of days in the week by the number of weeks.

So

4 x 7 = 28

There are 28 days in 4 weeks.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

There are 7 days in a week, so to convert weeks to days, we multiply the number of weeks by 7. For example, if we have 2 weeks, we would multiply 2 by 7 to get 14 days.

In this case, we are given 4 weeks and asked to convert it to days. So we multiply 4 by 7 to get:

4 x 7 = 28

Therefore, there are 28 days in 4 weeks.

this situation?

Answers

Answer: 147 votes

Beacause they need to find out what to do with the beach house

The greatest value in the range for this situation is $2,675.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Let the number of days the beach house is rented be represented by the variable "d".

If d is less than or equal to 7, then the total cost can be calculated as:

Total Cost = 375d + 100

If d is greater than 7, then the maximum cost would be reached by renting the house for 7 days and adding the $100 cleaning fee.

In this case, the total cost can be calculated as:

Total Cost = 375(7) + 100 = 2,675

Therefore,

The greatest value in the range for this situation is $2,675.

Step-by-step explanation:

Area of square + Area of triangle + Area of rectangle = Area of figure shown

=> (4 x 4) + (1/2 x 4 x 2) + (2 x 4) = Area of figure shown

=> 16 + 4 + 8 = Area of figure shown

=> 28 = Area of figure shown

Therefore, the area of the figure is 28 units.

Hoped this helped.

Answer:

28 units.

Step-by-step explanation:

Act like the shape is just a normal rectangle, because thats easy to do. If it was a full rectangle the length would be 8 and the width would be 4. The formula for finding area of a rectangle is length times width so 8x4 is 32. Now, to find the actual area of the shape, you have to subtract a bit. (I'll add a picture to better explain what I am meaning) You imagine see a mini rectange in the corner with a length of 4 and a width of 2. The area for that is 8. But, only half of that imaginary rectangle is in the actual shape so subtract half of that shape (4) from the original 32 and you get 28. The area is 28 units.

1x - y = 10                Do not change ⇔     1x -  y =  10  

                                                                     -x   = 3

                                                                      x = -3

Use the second equation to solve on y when x = -3

-1x - y = 10

-1(-3) - y = 10

 3 - y = 10

    -y = 10 - 3
