The supplied statement states that the candle would reach a height of 14.85 cm after 24 hours.

The terms "altitude" and "elevation" refer to the vertical distance between something's top and bottom or its base and it's something above it. Height is used to describe everything that may be measured vertically, high or low.

Let Y = height.

let X equal time

Y = mX + b, where the slope of m & b is the y-intercept, denotes the linear relationship between height and time.

We can determine the slope using the information provided (13, 15.4) and (29, 6.5)

Slope = (y2 - y1) / (x2 - x1) = (6.5 - 15.4) / (29 - 13) = -8.9 / 16 = -0.55

This indicates that the candle is losing height at a rate of 0.55 cm each hour.

As the first grid cell of 24 hours comes 13 hours afterwards, (13, 15.4), the height will go down by 13 * (-0.55) = -7.15 cm in the 13 hours between hour 13 and hour 24.

Hence, the candle's height 24 hours later = 15.4 - 0.55 = 14.85 centimeters

Answer:

30 cm²

Step-by-step explanation:

The formula to find the area of a parallelogram.

Area = Base × Height

Accordingly, let us find the area.

Area = Base × Height

Area = 10 cm × 3 cm

Area = 30 cm²

The area of the blue-shaded region is 19.95 m²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a rectangle with length 14 m, and diagonal 15.5 m, a parallelogram has been cut out of it, we need to find the area remaining,

Using the Pythagoras theorem,

15.5² = 14²+w² [width]

w² = 240.25-196

w² = 44.25

w = 6.65

Therefore, the width of the rectangle is 6.65 m

That mean, the height of the parallelogram is 6.65 m,

The area of the blue-shaded region, is calculated by subtracting the area of the parallelogram by the area of the rectangle,

Area of the remaining region = 14×6.65-11×6.65

= 6.65(14-11) = 6.65×3

= 19.95 m²

Hence, the area of the blue-shaded region is 19.95 m²

Finally, we can use the earlier equations to find the number of bass and bluegills in pond B:

2x + 6y = 300

2(15) + 6(45) = 300

30 + 270 = 300

Therefore, pond B has 30 bass and 270 bluegills.

In algebra, a statement of mathematics that proves the equality of two mathematical expressions is known as an equation. Consider the equation 3x + 5 = 14, where the word "equal" is used to denote the relationship between the terms 3x + 5 and 14.

Let's denote the number of bass in pond A as "x" and the number of bluegills in pond A as "y".

According to the problem, Gage stocks pond B with twice the amount of bass as pond A, so the number of bass in pond B is 2x. He also stocks pond B with six times the amount of bluegills as pond A, so the number of bluegills in pond B is 6y.

We know that Gage stocks pond A with a total of 60 fish, so:

x + y = 60

We also know that Gage stocks pond B with a total of 300 fish, so:

2x + 6y = 300

x + 3y = 150

Now we have two equations:

x + y = 60

x + 3y = 150

We can solve for x in the first equation:

x = 60 - y

Substitute this expression for x into the second equation:

(60 - y) + 3y = 150

2y = 90

y = 45

Now that we know that pond A has 45 bluegills, we can use the equation x + y = 60 to find that pond A has 15 bass (since 45 + 15 = 60).

2x + 6y = 300

2(15) + 6(45) = 300

30 + 270 = 300

Therefore, pond B has 30 bass and 270 bluegills.

This expression gives the mean number of coupons you will need to collect before you have a complete set, given that each coupon obtained is equally likely to be any one of the c types.

In general, probability is a measure of the likelihood that a certain event or outcome will occur. It is a branch of mathematics concerned with analyzing and quantifying uncertainty. In formal terms, the probability of an event is a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain. Probabilities between 0 and 1 represent the degree of uncertainty associated with the event.

Here,

The probability that the first n coupons collected do not form a complete set can be found as follows:

Let S be the event that the first n coupons do not form a complete set, and let Ci be the event that the i-th coupon collected is a new type (i.e., a coupon of a type that has not been collected before).

Then, the event S can be expressed as the intersection of the events C1, C2, ..., Cn, where each Ci is independent of the others and has probability (c-i+1)/c of occurring. This is because there are c-i+1 types of coupons remaining after i-1 types have been collected, and each of these types is equally likely to be the next coupon collected.

So, the probability of S can be calculated as:

P(S) = P(C1 ∩ C2 ∩ ... ∩ Cn) = P(C1) × P(C2) × ... × P(Cn)

= (c-1)/c × (c-2)/c × ... × (c-n+1)/c

= Π(i=1 to n) (c-i+1)/c

To deduce an expression for the mean number of coupons you will need to collect before you have a complete set, let X be the random variable representing the number of coupons collected until a complete set is obtained. Then, the expected value of X can be calculated using the formula:

E(X) = Σ(k=1 to c) P(X ≥ k)

This formula sums the probabilities of all possible numbers of coupons collected until a complete set is obtained, weighted by their respective probabilities.

Note that P(X ≥ k) is the probability that a complete set has not been obtained after k-1 coupons have been collected, which is equal to the probability of the event S above. So, we can substitute the expression for P(S) into the formula for E(X) to get:

E(X) = Σ(k=1 to c) P(X ≥ k)

= Σ(k=1 to c) Π(i=1 to k-1) (c-i+1)/c

= Σ(k=1 to c) Π(i=0 to k-2) (c-i)/c

= Σ(k=0 to c-1) Π(i=0 to k-1) (c-i)/c (by changing the index of summation)

= Σ(k=0 to c-1) (c-k)/cˣ

= c Σ(k=0 to c-1) (1/c)ˣ - Σ(k=0 to c-1) (k/c)ˣ

= c (1 - (1/c)ˣ)/(1 - 1/c) - B(c, 1/c)

where B(c, 1/c) is the sum of the first c terms of the series (k/c)ˣ.

Step-by-step explanation:

a. The average rate of change in DVD sales during this period can be calculated as:

average rate of change = (change in DVDs sold) / (change in years)

We are given that in 2011, 6.1 billion DVDs were sold, and in 2021, 1.2 billion DVDs were sold. The change in DVDs sold is:

change in DVDs sold = 1.2 billion - 6.1 billion = -4.9 billion

The change in years is:

change in years = 2021 - 2011 = 10

So the average rate of change in DVD sales during this period is:

average rate of change = (-4.9 billion) / 10 = -0.49 billion DVDs per year

Therefore, DVD sales declined by an average of 0.49 billion per year during this period.

b. Using the numbers in 2011 as an initial value, we can write a linear model that models the number of DVD sales worldwide as:

DVD sales = -0.49(t - 2011) + 6.1

where t is the year and DVD sales are measured in billions.

c. If the rate stays the same, we can predict the number of DVD sales in the year 2023 by substituting t = 2023 into the linear model and solving for DVD sales:

DVD sales = -0.49(2023 - 2011) + 6.1 ≈ 0.5 billion DVDs

Therefore, if the rate of decline in DVD sales stays the same, we can predict that there will be about 0.5 billion DVDs sold worldwide in 2023.

Step-by-step explanation:

Let's assume the number of boys in the class is "x". Then, according to the problem, the number of girls in the class is 2.5 times the number of boys, which can be expressed as:

number of girls = 2.5 * number of boys

We also know that the total number of students in the class is 35. Therefore, we can write an equation in terms of "x" as follows:

x + 2.5x = 35

Simplifying the above equation, we get:

3.5x = 35

Dividing both sides by 3.5, we get:

x = 10

This means that there are 10 boys in the class. To find the number of girls, we can use the equation we derived earlier:

number of girls = 2.5 * number of boys

number of girls = 2.5 * 10 = 25

Therefore, there are 25 girls in the class.
