The value of the car decreases from year to year by 15%.

A kind of function that would explain this type of pattern is an exponential decay function [tex]f(x) = 10000(0.15)^x[/tex].

You need the decay rate to find the function the actuary is using.

In Mathematics and Statistics, a population or physical asset (car) that decreases at a specific period of time represent an exponential decay. This ultimately implies that, a mathematical model for any population or physical asset that decreases by r percent per unit of time is an exponential equation of this form:

P(t) = I(1 - r)^t

Where:

Next, we would determine the constant ratio in each representation as follows;

Constant ratio, r = a₂/a₁ = a₃/a₂ = a₄/a₃ = a₅/₄

Constant ratio, r = 8520/10,000 = 7213/8250 = 6,100/7213 = 768/192

Constant ratio, r = 85.

By substituting the given parameters, we have the following:

P(t) = I(1 - r)^t

f(x) = 10,000(1 - 85/100)^x

f(x) = 9,600(1 - 0.85)^x

f(x) = 9,600(0.15)^x

Answer: figure ii

Step-by-step explanation:

The quarts of paint used by Mieko to paint his living room is equal to 3 quarts.

Total paint bought by Mieko = 2 gallons

Amount of paint used  to paint bedroom = 1/4 of the paint.

Amount of paint used on the hallway = 3 quarts

Since 1 gallon is equal to 4 quarts.

Convert gallons to quarts.

Mieko bought 2 gallons of paint, which is equivalent to 8 quarts

She used 1/4 of the paint on her bedroom,

which is 1/4 x 8 quarts = 2 quarts.

She also used 3 quarts of paint on the hallway.

This implies,

The total amount of paint used on the bedroom and hallway is equal to,

2 quarts + 3 quarts = 5 quarts

The amount of paint used in the living room is the remaining amount of paint is equal to,

8 quarts - 5 quarts = 3 quarts

Therefore, Mieko used 3 quarts of paint in the living room.

Answer:

MO/KO = NO/LO

5/10 = 3/LO

5/10 = 3/x

Step-by-step explanation:

Since KLO and MNO are similar, that means the corresponding sides share a common proportion:

Note how corresponding sides MO and KO are given measurements, that means we can find the common proportion by dividing MO/KO (which is 5/10). Knowing the proportion between the corresponding sides between MO and KO, we can find LO by finding its corresponding side and setting up a proportion. LO's corresponding side is NO (with a measurement of 3):

5/10 = 3/LO

Other options also work:

MO/KO = NO/LO               since MO = 5 units, KO = 10 units, & NO = 3 units

5/10 = 3/x                           since any value can be set to a variable, LO = x

The slope and y-intercepts of each line, respectively, are:

5. m = -2; b = 6       6. m = 5/3; b = 10/3       7. m = -1/4; b = 4

Slope of a line is calculated as, m = change in y / change in x.

5. Given (2, 2) and (3, 0):

Slope of the line (m) = change in y / change in x = 2 - 0 / 2 - 3

m = 2/-1

m = -2

To find the y-intercept (b), substitute m = -2 and (x, y) = (2, 2) into y = mx + b:

2 = -2(2) + b

2 = -4 + b

2 + 4 = b

b = 6

6. Given (1,5) and (4, 10):

Slope of the line (m) = change in y / change in x = 10 - 5 / 4 - 1

m = 5/3

To find the y-intercept (b), substitute m = 5/3 and (x, y) = (1, 5) into y = mx + b:

5 = 5/3(1) + b

5 - 5/3 = b

b = (15 - 5)/3

b = 10/3

7. Given (8, 2) and (-8, 6):

Slope of the line (m) = change in y / change in x = 6 - 2 / -8 - 8

m = 4/-16

m = -1/4

To find the y-intercept (b), substitute m = -1/4 and (x, y) = (8, 2) into y = mx + b:

2 = -1/4(8) + b

2 = -2 + b

The apothem is the vocabulary for a. The regular polygon's area is 319.8 cm².

We may use the following formula to calculate the area of the polygon:

Area = (1/2) × Perimeter × Apothem

The perimeter of a polygon is calculated by multiplying the number of sides by the length of each side, as shown below:

Perimeter = the number of sides multiplied by the length of each side

Perimeter = 6 × 14 cm (because to the regular hexagon shape)

Perimeter = 84 cm

Use the fact that it forms a right triangle with half of one side length and the apothem as the legs and the apothem as the hypotenuse to find the apothem. Thus,

a² = s² - (s/2)²

a² = 196 - 49

a² = 147

a = √(147) = 7.65 cm

Now we can enter our values into the area formula:

Area = (1/2) × Perimeter × Apothem

Area = (1/2) × 84 cm × 7.65 cm

The probability of obtaining a head on the next toss of a coin after obtaining two heads from two tosses is still 1/2 or 50%.

This is because each coin toss is an independent event, and the outcome of one toss does not affect the outcome of another toss. Therefore, the fact that two heads have been obtained in the previous two tosses does not change the probability of obtaining a head on the next toss, which is always 1/2 or 0.5 for a fair coin.

Probability is the likelihood of an event occurring. The values are between 0 and 1. The closer it is to 1, the greater the probability.

Answer:

To solve the equation, we can begin by isolating the expression in the parentheses:

2(x^2 + x - 11)^3/2 = 54

Divide both sides by 2:

(x^2 + x - 11)^3/2 = 27

Take the cube root of both sides:

x^2 + x - 11 = 3∛27

Simplify the cube root:

x^2 + x - 11 = 3∛(27) = 3*3 = 9

Rearrange the equation:

x^2 + x - 20 = 0

Factor the quadratic:

(x + 5)(x - 4) = 0

Therefore, the solutions are x = -5 and x = 4.

To check for extraneous solutions, we need to make sure that these values do not make the original equation undefined. Since there are no square roots or denominators, there are no restrictions on x, and both solutions are valid.

So, the solutions to the equation are -5 and 4, in increasing order.

a) Number of elements in sample size is 11.

b) Probability P(E) is 0.45.

a) The sample space is the set of all possible outcomes when drawing a single card from the deck. Since there are 11 cards in total, the sample space has 11 elements.

b) We want to find the probability of drawing an even-numbered card, which includes the red cards numbered 2, 4, and 6, and the black cards numbered 2 and 4. There are five such cards in total, so the probability of drawing an even-numbered card is:

P(E) = number of even-numbered cards / total number of cards

P(E) = 5 / 11

P(E) = 0.4545 or approximately 0.45

Therefore, the probability of drawing an even-numbered card from the deck is about 0.45.

The expected number of trips a customer needs to make to get a complete set of letters is 6 trips.

This problem can be modeled using the concept of a geometric distribution, where the number of trials required to achieve the first success (getting a complete set of letters) follows a geometric distribution.

The probability of getting a specific letter on any given purchase is 1/6, since there are six letters and they are equally likely to be given away. Therefore, the probability of not getting a specific letter on any given purchase is 5/6.

Let X be the random variable representing the number of purchases needed to obtain a complete set of letters. Since each purchase is independent of the others, X follows a geometric distribution with a probability of success p = 1/6.

The expected value of a geometric distribution with probability of success p is given by E(X) = 1/p. Therefore, the expected number of trips to the store that a customer needs to make to get a complete set is:

The total number of students on the honor roll increased by approximately 19.3%.

What is percenatge?

Percentage is a way of expressing a fraction or a portion of a whole number as a portion of 100. It is often denoted by the symbol %. For example, 50% represents 50 parts out of 100, or 50/100, which simplifies to 1/2.

Let's first find the total number of students on the honor roll last year:

Total number of students on the honor roll last year = 100 (boys) + 50 (girls) = 150

This year, the number of boys on the honor roll increased by 19%, which means the new number of boys on the honor roll is:

New number of boys on the honor roll = 100 + 0.19(100) = 119

Similarly, the new number of girls on the honor roll is:

New number of girls on the honor roll = 50 + 0.20(50) = 60

Therefore, the total number of students on the honor roll this year is:

Total number of students on the honor roll this year = 119 (boys) + 60 (girls) = 179

The percentage increase in the total number of students on the honor roll is:

Percentage increase = [(Total number of students on the honor roll this year - Total number of students on the honor roll last year) / Total number of students on the honor roll last year] x 100%

Percentage increase = [(179 - 150) / 150] x 100% = 19.3%

The equation of a circle having endpoints of diameter as (4,9) and (4,-3) is (x - 4)² + (y - 3)² = 36.

The "center" of circle is called as midpoint of diameter.

The "x-coordinate" of "mid-point" is = (4+4)/2 = 4, and

The "y-coordinate" of "mid-point" is = (9+(-3))/2 = 3.

So, center of circle is (4,3),

The radius of circle is half the length of the diameter, which is distance between two endpoints of diameter. We find distance using distance formula:

⇒ distance = √((x₂ - x₁)² + (y₂ - y₁)²), where (x₁,y₁) and (x₂,y₂) are "end-points" of diameter.

⇒ distance = √((4 - 4)² + (9 - (-3))²)

⇒ √(144) = 12.

So, radius is 6.

The equation of circle with center (h,k) and radius "r" is : ⇒ (x - h)² + (y - k)² = r²,

Substituting the values

We get,

⇒ (x - 4)² + (y - 3)² = 6²,

⇒ (x - 4)² + (y - 3)² = 36,

Therefore, the equation of the circle is (x - 4)² + (y - 3)² = 36.
