Step-by-step explanation:

To calculate the probability of winning any amount of money, we need to sum up the probabilities of winning each individual prize.

Given the probabilities stated on the game card:

Probability of winning $10 prize = 0.2

Probability of winning $5 prize = 0.1

Probability of winning $0 prize = 0.7

To find the probability of winning any amount of money, we add these probabilities together:

0.2 + 0.1 + 0.7 = 1

The sum of the probabilities is 1, which indicates that the total probability of winning any amount of money is 1 or 100%.

Therefore, the probability of winning any amount of money in this game is 100%.

If the commercial banking system actually lends out the maximum amount it is able to lend, the excess reserves will be reduced to zero. This is because there will be no excess reserves held by the commercial banking system after lending out $9 billion.

Given that the required reserve ratio is 30 percent and all figures are in billions, the following table shows the total reserves, excess reserves, and required reserves:

Required reserve ratio 30% Checkable deposits $140Billion Reserves required (30% of checkable deposits)$42Billion Reserves held $51Billion Excess reserves held $9Billion Loans outstanding $109Billion Total Securities $100Billion Total Property $10Billion Total Assets $260Billion Stock shares $130Billion Total liabilities $130Billion Net worth (total assets - total liabilities) $130Billion.

Therefore, the total reserves held is $51 billion, and the reserves required is 30% of $140 billion, which is $42 billion.

This implies that the excess reserves are $9 billion.The maximum amount the commercial banking system can lend out is $51 billion minus $42 billion, which is $9 billion.

This indicates that if the commercial banking system actually lends out the maximum amount it is able to lend, the excess reserves will be reduced to zero. This is because there will be no excess reserves held by the commercial banking system after lending out $9 billion.

Answer:

D. its a two dimensional object

Answer:

A. It is a polygon

C. It is a one-dimensional object

The shape is a polygon in two dimensions since a polygon must have at least three straight sides.

In a pie chart, the sum of the angles for each variable or item is 360 degrees. also, the total percentage is 100

Looking at each flavor,

27% chose Glazier freeze, = 27/100 * 360 = 97.2 degrees

25% chose Fierce grape = 25/100 * 360 = 90 degrees

15.5% chose Extreme Citrico = 15.5/100 * 360 = 55.8 degrees

13.5% chose Cool Blue = 13.5/100 * 360 = 48.6 degrees

11.5% chose Lemon ice = 11.5/100 * 360 = 41.4

We want to determine the degrees for others

Therefore,

97.2 + 90 + 55.8 + 48.6 + 41.4 + others = 360

333 + others = 360

others = 360 - 333

others = 27 degrees

The correct option is C

The concept used is converting the given percentages to degrees and equation them to 360 degrees

100% is equivalent to 360 degrees

The GCF is the "Greatest Common Factor". The factors of 12 are 1, 2, 3, 4, 6, 12. The Factors of 18 are 1, 2, 3, 6, 9, 18. This would mean the GCF of these two numbers are 6. The sum is obviously 30. You could do something like 3(2+8 Which would mean 3x2=6 + 3x8=24.

The axis of symmetry is x = -1 and the vertex is (-1, -2).

A parabola is a U-shaped curve that can be formed by graphing a quadratic function. It is a type of conic section, which is a curve formed by intersecting a plane with a cone at a certain angle.

To graph the function F(x) = x² + 2x - 1, we can first find the vertex and axis of symmetry using the formula:

x = -b/2a

where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = 2, so:

x = -2/(2*1) = -1

So the axis of symmetry is x = -1. To find the vertex, we can substitute this value of x into the function to get:

F(-1) = (-1)² + 2(-1) - 1 = -2

So the vertex is (-1, -2).

To graph the function, we can plot the vertex and then use symmetry to plot points on either side of the axis. We can also note that since a = 1 is positive, the parabola opens upward.

A rough sketch of the graph is shown.

The x-axis represents the axis of symmetry, and the y-axis represents the values of the function F(x). The vertex (-1, -2) is marked with an "x", and other points on the graph are marked with "x" to show the general shape of the parabola.

Answer:

1.875

Step-by-step explanation:

To find the average rate of change, we will draw a line from the initial point (1850) to the final point (2010, 300B) as shown in the image provided

Now, we just have to find the slope of this line

We know that slope = Rise /Run

from the image, we know that the rise = 300 and the run is 160

Hence,

Slope = 300 / 160

Slope = 1.875

Therefore,

The average rate of change of cigarette consumption is 1.875 Billion

What is a quadratic equation?

Any equation that can be written in the standard form where x is an unknown value, a, b, and c are known quantities, and a 0 is a quadratic equation. A quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Here, we have

Given: d = -16t² + 12t

To find: t using the quadratic formula

If we have a quadratic equation in the form ax² + bx + c = 0

then, by the quadratic formula we have

x = (-b±√b²-4ac)/2a

Rewrite the given equation,

-16t² + 12t - d = 0

from this equation we have,

a = -16 , b = 12 , c = d

now using the quadratic formula we get,

t = (-12±√12²-4(-16)(d))/2(-16)

t =  (-12±√144+64d)/(-32)

t =  (-12±4√9+4d)/(-32)

t =  (-3±√9+4d)/(-8)

Hence, the value of t is  (-3±√9+4d)/(-8).

Help Center to Water Slide #1: Level line, y = 3. Toddler area to Concessions: Negative incline, y = (-1/3)x - 7. Gift Shop to Restrooms: Level line, y = -9. Security desk to Water Slide #2: Even line, y = 4. Lazy river to large Whirlpool: Positive incline, y = (2/5)x + 61/5.

To calculate the slope between attractions and discover the midpoints, we'll utilize the given requested sets for each fascination. Here are the calculations:

Help Center to Water Slide #1:

Slope = ((y2 - y1) / (x2 - x1)) = ((3 - 3) / (-6 - 2)) = / -8 =

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((2 + (-6)) / 2), ((3 + 3) / 2)) = (-2, 3)

Toddler area to Concessions:

Slope = ((y2 - y1) / (x2 - x1)) = ((-6 - (-3)) / (6 - (-3)) = (-3 / 9) = -1/3

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((-3 + 6) / 2), ((-9 + (-6)) / 2)) = (1.5, -7.5)

Gift Shop to Restrooms:

Slope = ((y2 - y1) / (x2 - x1)) = ((-9 - (-9)) / (8 - 2)) = / 6 =

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((8 + 2) / 2), ((-9 + (-9)) / 2) = (5, -9)

Security desk to Water Slide #2:

Slope = ((y2 - y1) / (x2 - x1)) = ((4 - 4) / (16 - 5)) = / 11 =

Midpoint = ((x1 + x2) / 2), ((y1 + y2) / 2)) = ((5 + 16) / 2), ((4 + 4) / 2) = (10.5, 4)

Lazy River to Large Whirlpool:

Slope = ((y2 - y1) / (x2 - x1)) = ((10 - 14) / (-7 - 3)) = (-4 / -10) = 2/5

Midpoint = ((x1 + x2) / 2)), ((y1 + y2) / 2)) = ((-7 + 3) / 2), ((10 + 14) / 2)) = (-2, 12)

Presently, let's calculate the linear equations for each case:

Help Center to Water Slide #1:

The Slope is 0, and the y-coordinate is consistent, so the equation is y = 3.

Toddler area to Concessions:

The Slope is -1/3, and the y-intercept can be calculated utilizing the midpoint facilitates:

-7.5 = (-1/3)(1.5) + b

-7.5 = -0.5 + b

b = -7

Gift Shop to Restrooms:

The Slope is 0, and the y-coordinate is steady, so the equation is y = -9.

Security desk to Water Slide #2:

The Slope is 0, and the y-coordinate is steady, so the equation is y = 4.

Lazy River to Large Whirlpool:

The Slope is 2/5, and the y-intercept can be calculated utilizing the midpoint arranges:

12 = (2/5)(-2) + b

12 = -4/5 + b

b = 61/5

The Linear equations for each case are as follows:

Help Center to Water Slide #1: y = 3

Toddler area to Concessions: y = (-1/3)x - 7
