The population of Greensville 10 years from now will be approximately 13,184.

To find the population of Greensville 10 years from now, we need to use the formula for compound interest:

A = P(1 + r)ᵗ

Where A is the future value, P is the present value, r is the annual interest rate as a decimal, and t is the number of years.

In this case, the present value (P) is 8,000, the annual interest rate (r) is 5.6% or 0.056 as a decimal, and the time (t) is 10 years. Plugging these values into the formula, we get:

A = 8,000(1 + 0.056)¹⁰

A = 8,000(1.648)

A = 13,184

This calculation assumes that the population growth rate remains constant at 5.6% per year.

The probability of drawing a second marble that is blue is 3/5

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

A red marble is drawn from a bag containing 3 red and 3 blue marbles.

If the marbles were not replaced, then we have

P(Red) = 3/6

Now there are

3 blue marbles and 2 red marbles left

So, we have

The probability of choosing a blue marble, after a red marble is

P(Blue) = 3/5

Evaluate

P(Blue) = 3/5

Hence, the probability of choosing a blue marble, after a red marble is 3/5

Answer:

The weight that does not round to 2.46 pounds is C 2.454 pounds.

Step-by-step explanation:

Based on the given information, the weights of the four similar packs of tomatoes are as follows:

Malcolm rounds the weights to the nearest hundredth pound. To round to the nearest hundredth pound, we look at the digit in the hundredths place. If it is 5 or greater, we round up the digit in the tenths place. If it is less than 5, we leave the digit in the tenths place as it is. Therefore, we can obtain the rounded weights as follows:

From the above rounded weights, we see that Pack C rounds to 2.45 pounds and does not round to 2.46 pounds. Therefore, the weight that does not round to 2.46 pounds is C 2.454 pounds.

Dice game for a particular child’s game are numbered 1-10. Then, the  likelihood of rolling a single one and ending up with an even number is 1/20.

The probability of rolling a single one is 1/10, since there is only one die face with the number one out of ten possible outcomes.

The probability of rolling an even number is 5/10, since half of the die faces are even numbers (2, 4, 6, 8, 10) out of ten possible outcomes.

To find the likelihood of both events happening together, we need to multiply their individual probabilities;

P(rolling a single one and ending up with an even number) = P(rolling a single one) x P(ending up with an even number)

= (1/10) x (5/10)

= 1/20

Therefore, the likelihood of rolling a single one and ending up with an even number is 1/20.

The shortest path from vertex A to vertex L in the given diagram is ABDGJLKFI, with a total length of 89.

We can find the length of the shortest path from vertex A to vertex L by calculating the sum of the shortest paths from A to C to F to I to L.

Using Dijkstra's algorithm, we can find the shortest path from A to C, then from C to F, then from F to I, and finally from I to L.

The shortest path from A to C is AB + BC = 3 + 16 = 19. The shortest path from C to F is CF = 25. The shortest path from F to I is FI = 21. The shortest path from I to L is IL = 24.

Therefore, the length of the shortest path from A to L is 19 + 25 + 21 + 24 = 89.

Answer:

Step-by-step explanation:

m = n + 1 + x/p

First, we can start by subtracting (n+1) from both sides:

m - (n+1) = x/p

Then, we can multiply both sides by p to isolate x:

p(m - (n+1)) = x

So the final answer is:

x = p(m - (n+1))

Answer:

a quotient is the result obtained by dividing one quantity by another.

The expanded form of log y^10 is either 10 log y or 10 ln y

Assuming that the base of the logarithm is not specified, we can use the change of base formula to expand the logarithm:

log y^10 = log (y^10) / log (base)

Since the base is not specified, we can use any base we like. For example, we can use base 10 or base e (natural logarithm).

Using base 10:

log y^10 = log (y^10) / log 10

= 10 log y / 1

= 10 log y

Using natural logarithm:

log y^10 = log (y^10) / log e

= 10 log y / 1

= 10 ln y

Therefore, the expanded form of log y^10 is either 10 log y or 10 ln y, depending on the base used.

If the value of a certain collectible card in dollars from January 2020 to May 2021 can be modeled by the function V(m)=250m² – 3,500m + 18,000, the value of the card was declining over the period 0 < m < 7.

To determine when the value of the collectible card was declining, we need to look for when the first derivative of the function is negative. If the first derivative of the function is negative over a certain period, then the function is decreasing over that period. The first derivative of the function V(m) is:

V'(m) = 500m - 3,500

To find when the value of the card was declining, we need to solve the inequality V'(m) < 0. Solving for m, we get:

500m - 3,500 < 0

500m < 3,500

m < 7

Therefore, the value of the card was declining over the period 0 < m < 7. This corresponds to the months from January 2020 to July 2020. During this period, the first derivative of the function V(m) is negative, which means the value of the card was decreasing.
