What is the common ratio of the following geometric sequence? 6,9,27/2,81/4,...
a. r=-2
b. r=2
c. r=3/2
d. r=2/3

As per the given least-square regression line the residual for the player is 12.6.

The term least square regression line in math is defined as  the line that makes the vertical distance from the data points to the regression line as small as possible.

Here we have the least square regression line as y = 280. 3 + 85. 7x.

As we all know that the residual is given by the difference between the observed point and the predicted point.

While we looking into the given problem the expected score over x hours is written as,

=> f(x) = 280.3 + 85.7x.

Here we need to find the residual for the player, then we have to apply the value of x as 3, then we get,

=> f(3) = 280.3 + 85.7 x 3 = 537.4.

As here we know that the observed score was of 550, hence the residual is calculated as,

=> R = 550 - 537.4 = 12.6.

The probability that Marta makes at least 2 of the 3 free throws is 0.972

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

Proportion of throws = 90%

Number of throws = 3

The probability that Marta makes at least 2 of the 3 free throws is calculated as

Probability = P(2) + P(3)

Each individual probability can be calculated using

P(x) = nCx * p^x * (1 - p)^(n - x)

Substitute the known values in the above equation, so, we have the following representation

Probability = 3C2 * (0.9)^2 * (1 - 0.9)^1 + 3C3 * (0.9)^3 * (1 - 0.9)^0

Evaluate the expressions

Probability = 0.243 + 0.729

So, we have

Probability = 0.972

Hence, the probability is 0.972

The big-Oh order of the expression f(n) = 24n²nlogn + 280 is O(n²), which means that the time complexity of the algorithm is proportional to n².

The big-Oh order is a way of measuring the growth of a mathematical expression in terms of time complexity. It is used in computer science to analyze algorithms and to predict their performance.

In this case, we are looking at the big-Oh order of the expression f(n) = 24n²nlogn + 280.

To determine the big-Oh order, we need to find the dominant term in the expression, or the term that grows the fastest as the input size (n) increases.

In this expression, the dominant term is 24n²logn, since it grows much faster than the constant term 280.

Now, we can simplify the expression further. The logarithmic term is a much slower growing term compared to the polynomial term, so we can ignore it.

This means that the big-Oh order of the expression is O(n²), which means that the time complexity of the algorithm represented by the expression is proportional to n².

This means that the time taken by the algorithm will increase rapidly as the input size (n) increases.

Answer:

EH IT WILL BE 20,000

Step-by-step explanation:

If the radius of the base of a cone is decreasing at rate of 2 cm/minute and the height is kept constant at 9 cm, the rate of change of the volume at radius 13 cm is 489.4 cm³/minute

To calculate the rate of change, we need to take the derivative of the variables with respect to time.

The volume of a cone is given by:

V = 1/3 . πr²h

Where:

r = radius of the base

h = height

Since the height of the cone is held constant, then the derivative with respect to time is:

dV/dt = 1/3 h. 2πr dr/dt

Parameters given:

dr/dt = 2 cm/minute

h = 9 cm

r = 13 cm

Hence,

dV/dt = 1/3 x 9 x 2π x 13 x 2

dV/dt = 489.4 cm³/minute

Hence, at radius 13 cm, the rate of change of the volume is 489.4 cm³/minute

It looks like there was typos in your question, most probably your question was:

I dont know if this is right because I cant see the last part in less its like that

the train's average speed was approximately 68 miles per hour.

To calculate the average speed of the train, we need to divide the distance traveled by the time taken.

Given:

Distance: 170 miles

Time taken: 4:18 PM - 1:48 PM = 2 hours and 30 minutes

To calculate the average speed, we first need to convert the time taken to hours. Since there are 60 minutes in an hour, we have:

Time taken = 2 hours + 30 minutes / 60 = 2.5 hours

Now we can calculate the average speed:

Average speed = Distance / Time taken

Average speed = 170 miles / 2.5 hours

Average speed = 68 miles per hour (rounded to the nearest whole number)

Therefore, the train's average speed was approximately 68 miles per hour.

The total value in cents of all coins in the any row would be 16 cents.

In the pattern you described, the coins are arranged in rows such that each subsequent row has one more coin than the previous row. Let's analyze the values of the coins to determine the total value in cents of all the coins in the th row.

Assuming the values of the coins are as follows:

Penny: 1 cent

Nickel: 5 cents

Dime: 10 cents

We can observe that the pattern repeats after every three coins. The first three coins in the pattern are penny, nickel, dime. These coins have a total value of 1 + 5 + 10 = 16 cents.

For the subsequent rows, the pattern repeats with an offset of 3. For example, in the fourth row, the coins are penny, nickel, dime, which have the same total value as the first row, i.e., 16 cents.

So, regardless of the value of "th" (the row number), the total value in cents of all the coins in that row will always be 16 cents.

Answer:

The correct option is The PLUS loan will have a higher balance by $34.10 at the time of repayment. Hence Option B is correct.

Step-by-step explanation:

The slope of the line that contains these points is 0.75.

The slope of a line is the change in y-values divided by the change in x-values. In other words, it is the rise over the run. We can use the points given to calculate the slope.

Let's take the first two points (9, -24) and (13, -21) and use the formula for slope:

slope = (y2 - y1) / (x2 - x1)

slope = (-21 - (-24)) / (13 - 9)

slope = (3) / (4)

slope = 0.75

We can do the same with the other two points (17, -18) and (21, -15):

slope = (-15 - (-18)) / (21 - 17)

slope = (3) / (4)

slope = 0.75

Since the slope is the same for both sets of points, we can conclude that the slope of the line that contains these points is 0.75.

The zeros of the function G(t) are given by t = -1 + √(20.25g) and t = -1 - √(20.25g).

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.

To find the zeros of the function G(t), we need to find the values of t that make G(t) equal to zero. So, we start by setting G(t) to zero and solving for t:

G(t) = 0

(t+1)2 - 20.25g = 0 [substituting G(t) in place of 0]

(t+1)2 = 20.25g [adding 20.25g to both sides]

t+1 = ±√(20.25g) [taking the square root of both sides]

t = -1 ± √(20.25g) [subtracting 1 from both sides]

So, the zeros of the function G(t) are given by t = -1 + √(20.25g) and t = -1 - √(20.25g).
