Answer:

216.

Step-by-step explanation:

To solve this expression, you can first simplify the expression inside the parentheses:

45 - (25 + 8) = 45 - 33 = 12

Then you can substitute this simplified expression back into the original equation and multiply by 18:

(12) X 18 = 216

The total deer population for year 8 will be D. about 2081 deer.

To calculate the total deer population, we use the mark-recapture formula where: N = M * C/R

M = Total number of deer population captured and marked

C = Total number of deer population that had or did not have a mark

R = Total deer population recaptured and marked

So, for the given problem, the figures are as follows:

M = 1608

C = 110

R = 85

N = 1608 * 85 = 176,880/85 = 2080.94

So, the estimated deer population is about 2081 deer.

Transactions are larger than others Bank B may be the cheaper option even if you make more than 35 transactions.

To compare the cost of using Bank A and Bank B need to consider the total cost based on the number of transactions.

Let's say you make x transactions in a month.

For Bank A the monthly cost is a fixed fee of $45 regardless of the number of transactions.

For Bank B the monthly cost is a fee of $20 plus $0.70 for each transaction.

So the total cost for Bank B is:

Total cost = $20 + $0.70x

The break-even point where the total cost of Bank A and Bank B are equal need to solve the following equation:

45 = 20 + 0.70x

Subtracting 20 from both sides, we get:

25 = 0.70x

Dividing both sides by 0.70, we get:

x = 35.71

If you make more than 35 transactions in a month Bank A is the cheaper option.

If you make fewer than 35 transactions Bank B is the cheaper option.

Analysis assumes that all transactions are of the same amount.

To compare the total cost of both banks based on the actual amounts of the transactions.

Using the law of sines, the value of a in the given triangle, to the nearest tenth, is calculated as: 19.9.

The law of sines that we would apply is given as:

sin A/a = sin B/b = sin C/c.

Given the following:

a = ?

A = 64 degrees

b = 17

B = 50 degrees

Plug in the values into the equation, sin A/a = sin B/b:

sin 64/a = sin 50/17

Cross multiply:

a * sin 50 = sin 64 * 17

Divide both sides by sin 50

a * sin 50 / sin 50 = sin 64 * 17 / sin 50

a ≈ 19.9 [nearest tenth]

The value of a to the nearest tenth is 20.0

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

Using sine rule to solve for a;

The side opposite to angle 64 is a and the side opposite to angle 50 is 17

a/sinA = b/sinB

a/sin64 = 17/sin50

asin50 = 17sin64

0.766a = 17 × 0.899

0.766a = 15.283

a= 15.283/0.766

Answer: see below. the answers are bolded.

Step-by-step explanation:

1. Since x+55 forms a straight line, x+55 = 180. Solve that equation and you get x = 125. All interior angles in a triangle = 180. That means: 55+45+y = 180. Solve that equation and you get y = 80.

2. 110+x forms a straight line. 110+x = 180. Solve that equation and you get x = 70. Now that you have x, and you know that the interior angles of a triangle add up to 180, set up an equation. 70 + 65 + y = 180. Solve, and

y = 45

With the values provided, we can find both the volume and surface area.

Volume:

Formula = pi x r^2 x h

---r is the radius, h is the height

Volume = pi x (3)^2 x 7

Volume = pi x 36 x 7

Volume = 252pi mi^3 = 791.68 mi^3

Surface Area:

Formula = 2 x pi x r x h + 2 x pi x r^2

---r is the radius, h is the height

Surface Area = 2 x pi x 3 x 7 + 2 x pi x (3)^2

Surface Area = 42pi + 18pi

Surface Area = 60pi mi^2 = 188.50 mi^2

The probability that a person's favorite pastime is cooking is 0.125 (or 12.5%).

To find the probability that a person's favorite pastime is cooking, we need to divide the number of people whose favorite pastime is cooking by the total number of people.

Given the following pastimes,

Reading = 25

Sports = 40

Crafts = 20

Cooking = 15

Others = 20

Since 15 people listed cooking as their favorite pastime. To find the total number of people, we can add up the number of people who listed each pastime:

Total = Reading + Sports + Crafts + Cooking + Others

Total = 25 + 40 + 20 + 15 + 20 = 120

Therefore, the probability that a person's favorite pastime is cooking is:

P(cooking) = Cooking  / Total

The solution to the equation is x = 1.6.

Let's start by distributing the 3 on the right side of the equation:

25 + 2x = 12x + 9

Next, we can simplify the equation by moving all the x terms to one side and all the constant terms to the other side. To do this, we'll subtract 2x from both sides:

25 = 10x + 9

Then, we'll subtract 9 from both sides:

The coordinates of point A' are (4,1) in the given rectangle.

According to the shown figure, the coordinate of the given rectangle can be written as:

The coordinates of vertice A are (4, 3)

As we know that the x-coordinate of the reflected point will be the same as the x-coordinate of the original point.

Therefore, the x-coordinate of point A' will be:

x-coordinate of A' = 4

Here, the y-coordinate of point A is 3, which is 1 unit above the line y = 2. So, the reflection of point A across the line y = 2 will be 1 unit below the line y = 2.

- P is the initial principal (the amount you deposit)

- e is Euler's number (approximately 2.71828)

- r is the interest rate (expressed as a decimal)

- t is the time period in years

[tex]g(x) = f(x) - 4[/tex]

Step-by-step explanation:

We have been given a graph for f(x) and a table for g(x) and we have to find the transformation to map f(x) to g(x)

Let's find the function values for f(x) and g(x) at specific (easily distinguishable) x values for both

x               f(x) from graph                        g(x) from table

0                         4                                                0

1                          3                                                -1

2                          4                                                0

The function values for f(x) for x =  -1 and x = 3 are a bit difficult to read since they do not cross at  a grid intersection          

From the above table we see that for a specific x, g(x) value is 4 less than the f(x) value

Therefore the transformation is
g(x) = f(x) - 4    

Therefore g(x) is shifted downward by 4 points

I have plotted both f(x) and g(x) using the transformation; You can see the points fit

Ignore this part if you wish

The equation for f(x) is
f(x) = (x - 1)² + 3  in vertex form

or

f(x) = x² − 2x + 4​ in polynomial form

g(x) will then be
x² - 2x + 4 - 4 = x² -2x

Using the laws of exponents, the equivalent expression would be 1 / 64.

To find the equivalent expression of ( 4 / 7 ) ⁻ ³  . 7 ⁻³, we can use the law of exponents.

Using this law, we get:

(( 7 ³ ) /( 4 ³ ) ) x ( 1/ 7 ³ )

( ( 7 ³ ) / ( 4 ³ ) )  x ( 1 / 7 ³ ) = 1 / (4 ³ )

The standard deviation of the data set is 11.75.

To calculate the standard deviation of the data set, we first need to find the variance, which is the average of the sum of squares of the differences between each data value and the mean. We already calculated the sum of squares of the differences in Part (c), which is 828.

The formula for variance is:

variance = sum of squares of differences / number of data values

Since we have six data values, the variance is:

variance = 828 / 6

variance = 138

Now we can calculate the standard deviation, which is the square root of the variance:

standard deviation = sqrt(variance)

standard deviation = sqrt(138)

standard deviation = 11.75 (rounded to two decimal places)

Therefore, the standard deviation of the data set is 11.75.
