Answer:

A (8.1 x 10^10)

Step-by-step explanation:

1. 1 billion is 1,000,000,000 or 10^9

2. 81 Billion should be 81 x 10^9, but the correct notation should always show a single digit number, so you need to also divide 81 per 10

3. Thus, the answer is 8.1 x 10^10

Answer:

8.1 × 10^10

The statement that correctly compares the two functions is

They have the same x-intercept and the same end behavior as x approaches ∞.

A function's final behaviour is represented by the value of f(x) as x approaches infinity. Both functions in this scenario have the same final behaviour because they both have unbounded growth, or they both go to positive infinity.

To find y-intercept of a function we have to put x= 0

So, The y-intercept of f(x) is y = -3.

and, The y-intercept of g(x) is y = -4.

To  find x -intercept of a function put y = 0

So, The x-intercept of f(x) is x = 1.

and, The x-intercept of g(x) is x = 1.

Answer:

$64,500:  Total cost for four years

Step-by-step explanation:

This problem involves an arithmetic progression in which the common difference is $750.  The first term is $15,000.  The general formula is then

a(n) = $15,000 + $750(n - 1)

Thus:

a(1) = $15,000

a(2) = $15,000 +$750 = $15,750

a(3) = $15,000 + 2($750) = $16,500

a(4) = $16,500 + $750 = $17,250

Summing up these costs, we get $64,500:  Total cost for four years

The total cost of tuition, books, and fees for this student when attending college for four years will be, $64651

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Assuming that the annual increase of $750 per year is compounded each year.

we can use the formula for the future value of an annuity to calculate the total cost of tuition, books, and fees for the four years:

FV = PMT ((1 + r)ⁿ - 1) / r

Now, In this case, PMT = $15,000, r = 750/15000 = 0.05, and n = 4.

Plugging in these values, we get:

Total cost or FV = $15,000 x ((1 + 0.05)⁴ - 1) / 0.05

FV = $15,000 x(1.2155)-1)/0.05

FV = $15,000 x 0.2155/0.05

FV = $15,000 x4.31

FV = $64651

Hence, the total cost of tuition, books, and fees for this student when attending college for four years will be $64651

Answer:

18,223 feet

Step-by-step explanation:

y= -16t^2 + 608t + 12,447.

y = -16(t² - 38t) + 12447

y = -16[t² - 2(t)(19) + 19² - 19²] + 12447

y = -16(t - 19)² - 16(-19²) + 12447

y = -16(t - 19)² + 18223

Vertex: (19, 18223)

Max height is 18,223 at t = 19

The parabolas are:

a = -16

b = 608

c = 12,447

x_v = -b/2a

t_v = -608/2(-16)

t_v = -608/-32

t_v = 19

Plug in t_v = 19 to find y_v

y = -16(19)^2 + 608(19) + 12,447

y = -16(361) + 11,552 + 12,477

y = -5,776 + 11,552 + 12,477

y = 18,253

We have the point (19, 18,253)

The max height is at 18,253 when t = 19

The unit measures in order from smallest to largest are as follows: grams, ounces, pounds, kilograms.

The gram is the smallest unit of measurement, followed by the ounce, pound, and kilogram. One gram is equal to 0.035 ounces, while one kilogram is equal to 2.205 pounds. Understanding the relationships between these units can be helpful for converting measurements between them, which is often necessary in fields such as science and cooking.

Pounds and kilograms are both measures of weight or mass, with kilograms being the larger unit. One kilogram is equal to approximately 2.2 pounds.

Ounces and grams are also measures of weight or mass, but are smaller units. One ounce is equal to approximately 28.35 grams.

So if you were to list these units in order from smallest to largest, it would be: grams, ounces, pounds, kilograms.

To transform the regression equation, you would divide both sides of the equation by the square root of Var(ut), which is σ√(zt). This transformation helps in obtaining the transformed regression coefficients and standard errors that account for the heteroscedasticity in the error term.

When the variance of the error term (ut) is related to a known variable (zt), it implies the presence of heteroscedasticity in the regression model. Heteroscedasticity means that the variability of the error term is not constant across different levels of the independent variables.

To address this issue, we can transform the regression equation by dividing both sides by the square root of the variance of the error term, which is σ√(zt). This transformation is known as the weighted least squares (WLS) estimation.

By dividing both sides of the equation, we can obtain the transformed regression equation with the error term divided by its standard deviation. This transformation accounts for the heteroscedasticity by giving different weights to the observations based on the variability of the error term. It allows for a more appropriate estimation of the regression coefficients and standard errors, as it gives more weight to observations with smaller error variances and less weight to observations with larger error variances.

According to the information provided, k and m are crossing lines with an angle of 86°. We know this because k and m are straight lines.

The angles add up to 180 degrees.

Then we receive,

\(a + 86 =180\)

Or, a = 180 -86

Or, a = 94°.

As a result, an is 94°.

The angle an is 94 degrees.

Supplementary angle are formed when two angles add to 180 degrees. When additional angles are added together, they form a straight angle, or 180 degrees. In these other words, if indeed the sum of angles 1 and 2 equals 180 degrees, angles 1 and 2 are supplementary. Angles 1 and 2 are referred to as "supplements" to one another in this context.

The true statements for the given function f(x) are:

The value of g(1) is 3 and the y- intercept of g(x) is at the point (0, 1) .

The function g(x) = f( x - 3 )

g (1) = f (1 -3 )

       = f (-2 )

       = 3

g (-1) = f (-1 -3)

       = f (-4)

       = - 1

Substituting , x = 0 to find the y intercept of g(x)

g ( 0 ) = f ( 0 - 3)

          =f (-3)

          =1

The y intercept of g(x) is at the point (0, 1)

Answer: (a) To find the probability that a hotel room costs $225 or more per night, we need to calculate the z-score first:

z = (225 - 204) / 55 = 0.3818

Using the standard normal distribution table or calculator, we find the probability that a z-score is greater than or equal to 0.3818 is 0.3524. Therefore, the probability that a hotel room costs $225 or more per night is 0.3524.

(b) To find the probability that a hotel room costs less than $110 per night, we need to calculate the z-score:

z = (110 - 204) / 55 = -1.7091

Using the standard normal distribution table or calculator, we find the probability that a z-score is less than or equal to -1.7091 is 0.0446. Therefore, the probability that a hotel room costs less than $110 per night is 0.0446.

(c) To find the probability that a hotel room costs between $200 and $280 per night, we need to calculate the z-scores for both values:

z1 = (200 - 204) / 55 = -0.0727

z2 = (280 - 204) / 55 = 1.3818

Using the standard normal distribution table or calculator, we find the probability that a z-score is between -0.0727 and 1.3818 is 0.5244. Therefore, the probability that a hotel room costs between $200 and $280 per night is 0.5244.

(d) To find the cost in dollars of the 20% most expensive hotel rooms in New York City, we need to find the z-score that corresponds to the 80th percentile:

z = invNorm(0.8) ≈ 0.8416

Using the z-score formula, we can find the corresponding hotel room rate:

z = (x - 204) / 55

0.8416 = (x - 204) / 55

x - 204 = 0.8416 * 55

x ≈ 250.29

Therefore, the cost in dollars of the 20% most expensive hotel rooms in New York City is approximately $250.29 per night.

The student's math score of 590 is equal to the average math score of students who have the same verbal score of 600.

The verbal and math scores are positively correlated with a correlation coefficient of 0.65. The student's verbal score of 600 corresponds to a z-score of 1.5, indicating that it is 1.5 standard deviations above the mean verbal score of 450. Similarly, the student's math score of 590 corresponds to a z-score of approximately 1.5, which means it is also 1.5 standard deviations above the mean math score of 425.

Since the z-scores for both the verbal and math scores are the same (approximately 1.5), we can conclude that the student's math score of 590 is equal to the average math score of students who have the same verbal score of 600. This suggests that the student's performance in math is consistent with what is expected based on their verbal score.
