the sum of interior angles is equal to exterior

A point that is Interior to an Angle is found on the Exterior of the Angle

The statement is false

How do we explain?

A point that is interior to an angle is located within the angle, not on the exterior. The interior of an angle refers to the region enclosed by the angle's sides.

A point that is interior to an angle is located within the angle, not on the exterior. When we refer to the interior of an angle, we are referring to the space enclosed by the angle's sides and vertex.

In geometric terms, an angle consists of two rays that share a common endpoint called the vertex. The interior of the angle is the region between these two rays while on the other hand, the exterior of an angle refers to the space outside the angle, beyond its sides.

In conclusion, a point that is interior to an angle is found within the angle itself, not on the exterior.

Step-by-step explanation:

Do rise over run but make sure B is negative as it is going downwards

Answer:

A= 2 B= 9/10 (0.9)

Step-by-step explanation:

to find the gradients, we need to use the formula:

rise / run ---> which is basically counting the "boxes" in both of the x and y axis and divide them together (rise=y, run=x)

like that

A:

x axis=5    y=10 ---> then we use the formula (rise/run) 10/5= 2

B

x axis=10    y=9 ---> then we use the formula (rise/run) 9/10= 0.9

Answer:

d=91

Step-by-step explanation:

Answer:   d=91

Step-by-step explanation:

First thing first, you have to use the distributive property. Distribute the 8 to the d-87.

(8*d) - (8*87) = 32  =    8d - 696= 32  

Next, you have to add 696 to both sides of the equation:

8d-696 +696= 32+696  =  8d= 728

Last step is to divide both sides by 8:

8d/8 = 728/8 =  

d= 91

We can check this by plugging the number 91 to the variable d in the equation:

(8*91) - (8 *87) = 32    =  728 - 696= 32

Step-by-step explanation:

For the equation, I am not entirely sure that is what your teacher is looking for, but it definitely works! : )

To make it I just said that it looked like there were three different equal parts to the figures, and the area of the parts increases by one every time. So I just added 1 to whatever number it is which gets the area of one of the parts, and multiplied it by 3!

For number 3, I just plugged it into the equation I just made.

The numerical length of line segment \(\(\overline{JL}\)\) is approximately -11.67 units.

To determine the numerical length of line segment \(\(\overline{JL}\)\), we need to determine the value of JL provided the equations; KL = 2x - 2, JL = 4X-9, and JK = 5X+2.

Since point K is on line segment \(\(\overline{JL}\)\), we can equate the lengths KL and JK and solve for x:

KL = JK

2x - 2 = 5x + 2

By rearranging the equation, we get:

2 - 2 = 5x - 2x + 2

0 = 3x + 2

3x = -2

\(x = -\frac{2}{3}\)\)

Now that we have the value of x, we can substitute it into the equation for JL to calculate its numerical length:

JL = 4x - 9

\(\(JL = 4\left(-\frac{2}{3}\right) - 9\)\\\\\)

\(\\\(JL = -\frac{8}{3} - 9\)\\\\\)

\(\(JL = -\frac{8}{3} - \frac{27}{3}\)\\\\)

\(\(JL = -\frac{35}{3}\)\)

Therefore, the numerical length of line segment \(\(\overline{JL}\)\) is \(\(-\frac{35}{3}\)\) or approximately -11.67 units.

The surface area of the rectangular prism is 1,355,531 cm2.

Surface area is a measure of the total area of the surface of an object. It is calculated by taking the total area of its faces, edges, and vertices and combining them into one figure. It is an important factor in determining the volume, mass, and other properties of a three-dimensional object. In the case of a cube, for example, the surface area is the sum of the areas of its six faces. It is also used to measure the total area of a two-dimensional object, such as a circle or a triangle.

The surface area of a rectangular prism is the sum of the areas of all of its faces. To find the surface area, one can use the formula A = 2lw + 2lh + 2hw, where l is the length, w is the width, and h is the height.

In this case, the length of the rectangular prism is 550 1/4 cm, the width is 412 3/4 cm, and the height is 275 1/8 cm. Using the formula, we can calculate the surface area of the prism as follows:

A = 2(550 1/4)(412 3/4) + 2(550 1/4)(275 1/8) + 2(412 3/4)(275 1/8)

A = 936,406 1/2 + 304,437 1/2 + 114,687 1/2

A = 1,355,531 cm2

Therefore, the surface area of the rectangular prism is 1,355,531 cm2.

a. To determine the necessary sample size with a 90% confidence level and an estimate within 1% of the population proportion, we can use the formula:

n = [(Z^2 * p * (1-p)) / E^2]

Where:
n = necessary sample size
Z = z-score for the desired confidence level (in this case, 1.645 for 90%)
p = estimated proportion from past surveys (in this case, 0.3)
E = allowable error (in this case, 0.01)

Plugging in the values, we get:

n = [(1.645^2 * 0.3 * (1-0.3)) / 0.01^2]
n = 610.09

Rounding up to the next whole number, the necessary sample size is 611.

b. To reduce the sample size, we can increase the allowable error. If we allow for an error of 0.05 instead of 0.01, we can recalculate the sample size using the same formula:

n = [(Z^2 * p * (1-p)) / E^2]

Where:
n = necessary sample size
Z = z-score for the desired confidence level (in this case, 1.645 for 90%)
p = estimated proportion from past surveys (in this case, 0.3)
E = allowable error (in this case, 0.05)

Plugging in the values, we get:

n = [(1.645^2 * 0.3 * (1-0.3)) / 0.05^2]
n = 98.19

Rounding up to the next whole number, the necessary sample size is 99. Therefore, by increasing the allowable error, we can reduce the sample size to 99. However, it's important to note that increasing the allowable error also increases the margin of error in the estimate.

The probability of drawing a non-heart on the first draw is 39/52.the probability of drawing a non-heart on the third draw is 37/50.Expected value=0.5578.HA is:((0.5544 - 4) / 4) x 100% = -89.14%.

Here are the main answers to each question: What is the probability no hearts are drawn?There are 52 cards in a standard deck. Since there are 13 hearts in a deck, there are 39 non-hearts. The probability of drawing a non-heart on the first draw is 39/52.

For the second draw, there are 38 non-hearts remaining and 51 total cards. Thus, the probability of drawing a non-heart on the second draw is 38/51. For the third draw, there are 37 non-hearts remaining and 50 total cards. Thus, the probability of drawing a non-heart on the third draw is 37/50.

Therefore, the probability of no hearts being drawn is:(39/52) x (38/51) x (37/50) = 0.4448 ≈ 0.45 or 45%8. What is the probability that all three cards drawn are hearts?The probability of drawing a heart on the first draw is 13/52. For the second draw, there are 12 hearts remaining and 51 total cards.

Thus, the probability of drawing a heart on the second draw is 12/51. For the third draw, there are 11 hearts remaining and 50 total cards. Thus, the probability of drawing a heart on the third draw is 11/50.

Therefore, the probability of all three cards being hearts is:(13/52) x (12/51) x (11/50) = 0.0026 or 0.26%9. What is the probability that one or two of the cards drawn are hearts?To find the probability that one or two of the cards drawn are hearts, we can subtract the probability of getting no hearts from 1.

That is, the probability of getting one or two hearts is:1 - 0.4448 = 0.5552 or 55.52%10. If one or two of the cards selected are hearts, the casino pays 1:2. If all three are hearts, the casino pays 5:1. Otherwise, the player loses. If a player bets 4 on this game, what is their expected value?.

Expected value = (Probability of winning x Amount won) - (Probability of losing x Amount lost)Probability of winning = Probability of one or two hearts + Probability of three hearts = 0.5552 + 0.0026 = 0.5578.

Amount won for one or two hearts = 4 x 1/2 = 2Amount won for three hearts = $4 x 5 = $20Probability of losing = Probability of no hearts = 0.4448Amount lost = 4.

Therefore, the expected value is:(0.5578 x 2) - (0.4448 x $4) = $0.5544 or 55 cents11.

What is the House Advantage (HA) of this game?.

The House Advantage (HA) is the amount the casino expects to make from each bet over the long run. It is calculated as the difference between the expected value and the amount bet, divided by the amount bet. In this case, the HA is:((0.5544 - 4) / 4) x 100% = -89.14%.

Since the HA is negative, this means that the player has an advantage over the casino in this game.

In other words, over the long run, the player is expected to win more than they lose. However, this does not mean that the player will win every time they play. The odds are still in favor of the casino over the short term, but over a large number of bets, the player is expected to come out ahead.
