At a bus stop, 8 people got off the bus and 10 people go on. This means that the number of passengers increased by 2.

Step-by-step explanation:

The first one would e -8-10=-18

Second one would just be wrong. Each goldfish would be 5/4 of a dollar, so it cannot be possibly represented by the equation.

It would just be 8x=10

The last one is correct because it accurately depicts 8 people getting off(-8) and 10 people getting on(+10) which means that the passengers increased by two. This corresponds to the given equation.

The exponential growth rate of wind power capacity in Fwe country is 0.228, rounded to three decimal places. The equation for an exponential function that can be used to predict the wind-power capacity in megawatts, t years after 2001 is y = 4791(0.228)^t. The year in which wind power capacity will reach 100,008 megawatts is 2034.

The exponential growth rate can be found by taking the natural logarithm of the ratio of the wind power capacity in 2011 to the wind power capacity in 2001. The natural logarithm of 46915/4791 is 0.228. This means that the wind power capacity is growing at an exponential rate of 22.8% per year.

The equation for an exponential function that can be used to predict the wind-power capacity in megawatts, t years after 2001, can be found by using the formula y = a(b)^t, where a is the initial value, b is the growth rate, and t is the time. In this case, a = 4791, b = 0.228, and t is the number of years after 2001.

To find the year in which wind power capacity will reach 100,008 megawatts, we can set y = 100,008 in the equation and solve for t. This gives us t = 23.3, which means that wind power capacity will reach 100,008 megawatts in 2034.

Answer:

\(1611 \text{ kilocalories}\)

Step-by-step explanation:

During 1960, x = 0 because x represents the years since 1960, and no years have passed since 1960.

So, to solve for g(x) (kilocalories eaten) during 1960, all we have to do is plug 0 in for x on the right side of the equation and simplify:

\(g(x) = 1611(1.013)^0\)

\(g(x) = 1611(1)\)

\(\boxed{g(x) = 1611 \text{ kilocalories}}\)

Remember that anything to the power of 0 is 1.

Answer:

$2696.63

Explanation:

The future value A and the present value P are related by the following equation

A = P(1 + rt)

Where r is the interest rate and t is the time.

Now, we need to convert 9 months to years as follows

9 months x 1 year / 12 months = 0.75 years

Then, replacing A = 3000, r = 15% = 0.15 and t = 0.75, we get:

3000 = P(1 + 0.15(0.75))

3000 = P(1 + 0.1125)

3000 = P(1.1125)

Now, we can solve for P

P = 3000/1.1125

P = 2696.63

Therefore, the present value is $2696.63

The calculated length of the side AB is 7.1 units.

To find the length of AB, we need to use the distance formula, which gives the distance between two points in a coordinate plane.

The distance formula is:

d = √((x2 - x1)^2 + (y2 - y1)^2)

So, for the line segment AB, we need to find the distance between the points A(-2.3, 5) and B(4.8, 5).

Substituting the coordinates into the distance formula, we get:

d = √((4.8 - (-2.3))^2 + (5 - 5)^2)

d = √((4.8 + 2.3)^2 + 0^2)

d = √(7.1^2)

d = 7.1

Answer:

the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

Step-by-step explanation:

The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:

Let us assume the package of chocolate chip cookie be x

And, the package of ginger bread is y

So,

According to the question

6x + 2y = $72

6x + 10y = $216

Now subtract equation 1 from equation 2

-8y = -144

y = $18

And, for x it would be

6x + $36 = $72

x = $6

Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

The revenue can be calculated by multiplying the selling price per Frisbee ($7) , company must sell 2000 Frisbees to break even. The answer is option C. 2000.

In the first year, a Frisbee company's operating cost is $10,000 plus $2 for each Frisbee.

The company sells each Frisbee for $7.

The number of Frisbees the company must sell to break even is the point where its revenue equals its expenses.

To determine the number of Frisbees the company must sell to break even, use the equation below:

Revenue = Expenseswhere, Revenue = Price of each Frisbee sold × Number of Frisbees sold

Expenses = Operating cost + Cost of producing each Frisbee

Using the values given in the question, we can write the equation as:

To break even, the revenue should be equal to the cost.

Therefore, we can set up the following equation:

$7 * x = $10,000 + $2 * x

Now, we can solve this equation to find the value of x:

$7 * x - $2 * x = $10,000

Simplifying:

$5 * x = $10,000

Dividing both sides by $5:

x = $10,000 / $5

x = 2,000

7x = 2x + 10000

Where x represents the number of Frisbees sold

Multiplying 7 on both sides of the equation:7x = 2x + 10000  

5x = 10000x = 2000

The expression that is a difference of squares with a factor of 5x - 8 is \(25x^2 - 64.\)

To identify the expression that is a difference of squares with a factor of 5x - 8, we need to understand what a difference of squares is and how it relates to the given factor.

A difference of squares is an algebraic expression of the form \(a^2 - b^2,\)where a and b are terms. It can be factored as (a - b)(a + b). In other words, it is the product of two conjugate binomials.

In this case, the given factor is 5x - 8. To determine the other factor, we can set it equal to (a - b) and look for the corresponding (a + b) factor.

Setting 5x - 8 equal to (a - b), we have:

5x - 8 = (a - b)

To find the corresponding (a + b) factor, we consider the signs. Since the given factor is 5x - 8, we can conclude that the signs in the factored expression will be (a - b)(a + b), where the signs alternate. This means the corresponding (a + b) factor will have a positive sign.

So, the (a + b) factor will be (5x + 8).

Now, we have both factors: (a - b) = (5x - 8) and (a + b) = (5x + 8).

To find the expression that is a difference of squares with a factor of 5x - 8, we multiply these two factors:

(5x - 8)(5x + 8)

Expanding this expression using the distributive property, we get:

\(25x^2 - 40x + 40x - 64\)

The middle terms, -40x and +40x, cancel each other out, resulting in:

\(25x^2 - 64\)

Therefore, the expression that is a difference of squares with a factor of \(5x - 8 is 25x^2 - 64.\)

Answer:

The number of people that attended the performance = 2,254

Amount collected at box office = $45,080

Step-by-step explanation:

For the theater to sell out a performance, it means it was filled to the brim( completely filled)

We have 7 sections, with 23 rows each

The total number of rows will be 23 * 7 = 161 rows

Since each row has 14 seats, the total number of seats will be 161 * 14 = 2,254 seats

Secondly we want to know how much was collected at the box office given the average ticket price

The amount collected at the box office = Number of seats * average ticket price = 2,254 * 20 = $45,080

The 90% confident interval is (0.6754, 0.7496).

The formula for the confidence interval for a proportion in a population is as follows:

p ± z(α/2) * √[ (p * ( 1 - p) / n) ]

Here,

p = sample proportion

n = size of the sample

z(α/2) = critical value of the normal distribution at α/2 (significant level divided by 2).

The value of z(α/2) is obtained from the standard normal distribution tables.

For getting the Sample proportion we know the formula,

Sample proportion(p) = Favoring the incumbent / Total voters

p = 285/400

p = 0.7125

Critical value at 90% confidence interval = 1.645 (From the z-distribution table)

The Margin of Error (ME) is the range in which the true population proportion may lie. It can be calculated as follows:

ME = z * SE

(SE) = √[ p * ( 1 - p ) / n ]

SE = √ [(0.7125 * 0.2875) / 400] = 0.0226

ME = 1.645 * 0.0226

ME = 0.0371

Confidence Interval = Sample Proportion ± Margin of Error

CI = 0.7125 ± 0.0371

0.7496

CI = (0.6754, 0.7496)

Hence, the 90% confidence interval for the proportion of all voters who support the incumbent governor is(0.6754, 0.7496).

Since you bring 12 items for 4 dinners, you have a total of 12 items to choose from.

For the first dinner, you need to choose 3 items out of the 12. You can do this in:

12 choose 3 = (12!)/(3!*(12-3)!) = 220 ways

For the second dinner, you have used up 3 items in the first dinner, so you have 9 items left to choose from. You need to choose 3 items out of the 9. You can do this in:

9 choose 3 = (9!)/(3!*(9-3)!) = 84 ways

For the third dinner, you have already used up 6 items, so you have 6 items left to choose from. You need to choose 3 items out of the 6. You can do this in:

6 choose 3 = (6!)/(3!*(6-3)!) = 20 ways

For the fourth dinner, you have already used up 9 items, so you have only 3 items left to choose from. You need to choose all 3 items. You can do this in:

3 choose 3 = (3!)/(3!*(3-3)!) = 1 way

Therefore, you can choose items for the first dinner in 220 ways, for the second dinner in 84 ways, for the third dinner in 20 ways, and for the fourth dinner in 1 way.

The answer is option C, 8√2.

The length of the diagonal side of the square is 8 fr. Hence the gardener wants to divide a square piece of lawn in half diagonally, which means to find the length of a diagonal bisector of a square. Let's solve the problem: Length of the diagonal side of the square = 8 fr.

Let's apply the Pythagorean theorem, which states that the square of the length of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Therefore, the formula to find the length of the diagonal (d) of the square with side a is given by d = a√2.

Now we can find the length of the diagonal of the square using the formula given above: d = a√2d = 8√2Thus, the length of the diagonal side of the square is 8 fr. Hence the length of the diagonal of the square is 8√2 fr. Therefore, the answer is option C, 8√2.
