Answer: Yes

Step-by-step explanation: This table does represent a function. A function is where each input has exactly one output. Since none of the x-values repeat, this would represent a function.

I believe that aside from the bar graph, the line graph would actually best suits to convey this information. Because just like the bar graph, we can actually see the peaks of the grades. And through the peaks, we can easily compare the grades one by one.

Step-by-step explanation:

The height of the tree will be 45 feet.

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.

A tree is standing next to a 40-foot-high building. the tree has an 18-foot shadow, while the building has a 16-foot shadow.

Let x be the height of a tree. Then we have

x / 18 = 40 / 16

x = 45 feet

The given function 3xy = 27 is not a linear function.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

A linear function is defined as when the function has the highest degree of expression is 1, such as y = mx + c.

here,
Given function,
3xy = 27,

Simplifying the function,
3xy = 27
xy = 27/3
y = 9/x

Since, from the definition of the function, the given function is 9 reciprocal of x and is said to be a reciprocal function.

Thus, the given function 3xy = 27 is not a linear function.

The values of sine, cosine, and tangent for angle θ, where (1, -1) is on its terminal side, are sin(θ) = -1, cos(θ) = 1, and tan(θ) = -1, knowing that the point lies in the fourth quadrant.

To find the values of the sine, cosine, and tangent of an angle θ where the point (1, -1) is on its terminal side, we first recognize that this point lies in the fourth quadrant of the coordinate system. In this quadrant, cosine is positive, and sine and tangent are negative.

The point (1, -1) gives us the x and y coordinates on the Cartesian plane, which correspond to the lengths of the adjacent side and the opposite side of the right-angle triangle formed by the radius (hypotenuse) from the origin to the point, and the axes. Assuming we're dealing with a unit circle (which has a radius of 1), we can directly use the coordinates (1, -1) to find the cosine and sine:

Hence, for angle θ, cos(θ) is 1, sin(θ) is -1, and tan(θ) is -1.

Based on the daily consumption calculated from the given data, Lee's cat eats approximately 91.25 pounds of cat food in a year.

The question is asking for the estimated number of pounds of food that Lee's cat eats in one year. Lee's cat consumes a five-pound bag of food in 20 days. So, let's first determine how much he eats in 1 day. If 5 pounds is consumed in 20 days, then in 1 day, the cat eats 5/20, or 0.25 pounds.

Since there are approximately 365 days in a year, we multiply this daily consumption by 365. So, 0.25 pounds/day * 365 days/year = 91.25 pounds/year.

So, the best estimate for the amount of cat food that Lee's cat eats in one year would be approximately 91.25 pounds.

Final answer:

The expected value for the game is $4, which means on average a player would expect to gain $4 before the entry fee. However, after subtracting the cost to play ($15), the net expected value is -$11, indicating a loss on average for each play.

Explanation:

To determine the expected value of the game mentioned, we first identify the possible outcomes and their corresponding probabilities. Next, we multiply each outcome value by its probability, and sum up these products. Finally, we deduct the cost of the game ($15) from the sum to find the expected net gain or loss.

Probability of picking a $5 bill = 4/10

The expected value (EV) calculation would be:

EV = (1/10 * $100) + (2/10 * $20) + (3/10 * $10) + (4/10 * $5) - $15

EV = ($10) + ($4) + ($3) + ($2) - $15

EV = $19 - $15

EV = $4

Therefore, the expected value for the game is $4. This means on average you would expect to gain $4 per game before considering the entry fee. Since you pay $15 to play, you need to subtract this from the $4 gain to obtain the net expected value, which would be -$11, indicating a loss in the long run.

The relationship between variance and standard deviation is simply:

s = standard deviation

s^2 = variance

s = sqrt (s^2)

Therefore calculating for s:

s = sqrt (144)

s = 12

So we get the standard deviation is simply 12 scores.

r/5 - 6 = -1

add 6 to both sides

r/5 = 5

multiply both sides by 5

r = 5 *5 = 25

r = 25

Answer:

11x^3 - 2x^2 + 3x + 11

Step-by-step explanation:

we need to find the sum of 4x^3 + 2x^2 - 4x + 3 and 7x^3 -4x^2 + 7x + 8

To find the sum we add both the polynomials

4x^3 + 2x^2 - 4x + 3 + 7x^3 -4x^2 + 7x + 8

To add the polynomials we combine like terms

4x^3 + 7x^3 = 11x^3

2x^2 - 4x^2 = -2x^2

-4x+7x= 3x

3+8 = 11

So final expression is 11x^3 -2x^2 +3x+11

when m = 5:

2k = 5+3

2k = 8

k = 8/2

k=4

when m = 7

2k = 7+3

2k =10

k = 10/2

k = 5

when m = 9

2k = 9+3

2k = 12

k = 12/2

k = 6

k = {4,5,6}
