Answer:

Step-by-step explanation:

Let P(t) be the fox population t years after 2000. We know that the population has a continuous growth rate of 4% per year, which means that the population increases by a factor of 1.04 each year. Therefore, we can model the population as:

P(t) = 21400 * 1.04^t

Here, we start with the population in the year 2000 (21400) and multiply it by 1.04 raised to the power of the number of years after 2000 (t).

For example, if we want to find the population in the year 2015 (15 years after 2000), we can plug t = 15 into the equation:

P(15) = 21400 * 1.04^15

= 21400 * 1.618

= 34694.8

Therefore, we can expect the fox population to be approximately 34,695 in the year 2015.

Answer: Yes

Step-by-step explanation:

Yes because the angles are both 120 degree's

(I'm not sure if this is right but btw I love your pfp :))

The measures of center or variability are greater than 5 degrees

This Week's Mean: (4 + 13 + 6 + 9 + 8) / 5 = 40 / 5 = 8

Last Week's Mean: (10 + 9 + 5 + 6 + 5) / 5 = 35 / 5 = 7

Then the ranges

This Week's Range: (13 - 4) = 9

Last Week's Range: (10 - 5) = 5

The MAD for both weeks

|(4 - 8)| + |(13 - 8)| + |(6 - 8)| + |(9 - 8)| + |(8 - 8)|

= 4 + 5 + 2 + 1 + 0 = 12

This Week's MAD: 12 / 5 = 2.4

|(10 - 7)| + |(9 - 7)| + |(5 - 7)| + |(6 - 7)| + |(5 - 7)| = 3 + 2 + 2 + 1 + 2 = 10

Last Week's MAD: 10 / 5 = 2

The probability that a student chosen at random from Jared's class does not own a trampoline is 5/12.

The probability that the student does not own a trampoline is equal to the number of students who do not own a trampoline divided by the total number of students in the class.

The number of students who do not own a trampoline is equal to the total number of students in the class minus the number of students who own a trampoline:

24 - 14 = 10

Therefore, the probability that a student chosen at random from Jared's class does not own a trampoline is:

P(not owning a trampoline) = 10/24

Simplifying the fraction,

P(not owning a trampoline) = 5/12

Therefore, the probability that a student chosen at random from Jared's class does not own a trampoline is 5/12.

The composition of f. g derived from the equations in the attached image is:  [tex]\frac{1}{10}(2x + 1)[/tex] and f+g as  √(4x-1))/(5x²+3)

Composition is a mathematical operation that combines two functions to form a new function. From our question, we are given two functions f(x) and g(x).

One of their composition can be represented by f(g(x)).f(g(x)) means function out of g(x) will serve as input x for function f(x). In a more simpler words, f(g(x)) is the function obtained by taking the output of g(x) and using it as the input for f(x).

Using the question given as an example,

For f.g:

Firstly, we have to compute the composition of f and g.

This can be expressed as:

f(g(x))f(g(x)) = f(√(4x-1))= 1/[5(√(4x-1))² + 3]= 1/[5(4x-1) + 3]

= 1/(20x + 10)

= [tex]\frac{1}{10}(2x + 1)[/tex]

For f+g:

To find f+g, we will just add the two functions together as below:

f+g = 1/(5x²+3) + √(4x-1)= (√(4x-1) + (5x²+3)

= √(4x-1))/(5x²+3)

So the answers are;

f.g: = [tex]\frac{1}{10}(2x + 1)[/tex]

Step-by-step explanation:

vertical angles theorem, which says that the vertical angles that are formed when two lines intersect are congruent.

The missing number in the ratios of numbers are 16:10     8:20 and 0:30

Ratios are quantitative relationships between two numbers that describe how many times one value can contain another

the given parameters are

Forks         16          8              ----

Spoons       10         ---            30

The numbers are written in ascending order of magnitude

Using AP,

for forks: a = 16, 2nd term = 8

common difference = 8-16 - -8

For spoons a = 10, 3rd term = a + 2d = 30

30 = 10 + 2d

30 -10 = 2d

d= 20/2 = 10

Therefore the 2nd term = 10+10=20

The table reappears as follows

Forks         16          8             0

Spoons       10        20          30

1. To find the probability that the length of a single trout taken at random from the pond is between 7 and 11 inches long, we need to use the normalcdf command with the given parameters. The formula for normalcdf is normalcdf(lower bound, upper bound, mean, standard deviation).

Thus, normalcdf(7, 11, 10.5, 1.2) = 0.6827.

Therefore, the probability that the length of a single trout taken at random from the pond is between 7 and 11 inches long is 0.6827.

2. To find the probability that the mean length of five trout taken at random is between 7 and 11 inches, we need to use the central limit theorem, which states that the sample mean will also follow a normal distribution with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size (i.e., sigma/sqrt(n)).

Thus, we first need to find the standard deviation of the sample mean, which is sigma/sqrt(n) = 1.2/sqrt(5) = 0.5367.

Then, we can use the normalcdf command with the given parameters. The formula for normalcdf is normalcdf(lower bound, upper bound, mean, standard deviation).

Thus, normalcdf(7, 11, 10.5, 0.5367) = 0.9468.

Therefore, the probability that the mean length of five trout taken at random is between 7 and 11 inches is 0.9468.

The number of each type of ad that the department can run each month are:

TV Ads = 32

Radio Ads = 12

Two formulas are indicated.

x + y + z = 64

1000x + 200y + 600z = 46400

they want as many tv ads as radio and news ads combined.

equation for that is x = y + z

since x = y + z, replace x with y + z in both equations to get;

y + z + y + z = 64

1000 * (y + z) + 200 * y + 600 * z = 46400

combine like terms and simplify to get:

2y + 2z = 64

1000y + 1000z + 200y + 600z = 46400

combine like terms again to get:

1200y + 1600z = 46400

From the information given, we have the following parameters;

Density = 5.4 g/cm³

Mass = Ikg = 0.71 kg

Cost per mass = $0. 51

Let's determine the volume of this cylinder:

Volume = mass / density

Substitute the values

Volume = 0.71 /5.4

Volume = 0.131 cm³

Thus, 0.131  cm³ costs $0.71

For the utility pole;

Volume = 2 πr²h

Where:

r is 17.8cm

height is 700cm

Volume = 3. 142 × 17.8 × 17.8 × 700

Volume = 696414.32 cm³

If  0.131  cm³ costs $0.71

Then  696414.32  cm³ will cost:

Therefore, using equation,

c + a = 290

5c + 9a = 2250

Multiply equation(i) by 5

5c + 5a = 1450

5c + 9a = 2250

subtract the equation

4a = 800

The solutions to y = –8x for x = 2, 4, and 8 are (2, –16), (4, –32), (8, –64), hence, option D is correct.

We are given the equation y = -8x and asked to find the solutions for x = 2, 4, and 8. To find the solutions, we substitute the given values of x into the given linear equation and solve for y.

For x = 2, we have,

y = -8x

y = -8(2)

y = -16

Therefore, the solution for x = 2 is (2, -16).

For x = 4, we have,

y = -8x

y = -8(4)

y = -32

Therefore, the solution for x = 4 is (4, -32).

For x = 8, we have,

y = -8x

y = -8(8)

y = -64

Therefore, the solution for x = 8 is (8, -64).

Step-by-step explanation:

The probability that the sum exceeds 5 is P ( A ) = 0.6111

Given data ,

To find the probability of getting two numbers whose sum exceeds 5 when rolling a single die twice, we need to count the number of outcomes where the sum of the two numbers is greater than 5, and then divide that by the total number of equally-likely outcomes.

The outcomes where the sum exceeds 5 are:

(2, 4), (2, 5), (2, 6)

(3, 3), (3, 4), (3, 5), (3, 6)

(4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

(5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

(6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

There are 22 outcomes where the sum exceeds 5 out of a total of 36 equally-likely outcomes.

So, the probability of getting two numbers whose sum exceeds 5 when rolling a single die twice is:

P(sum > 5) = 22 / 36 ≈ 0.6111 or approximately 61.11 %
