If a model predicting minutes includes "ftmade" as an explanatory variable, the model would have two parameters: the intercept and the slope of "ftmade." The intercept represents the expected minutes when "ftmade" is zero, and the slope represents the expected increase in minutes for every one-unit increase in "ftmade."
The number of parameters in a model that predicts mins by including ftmade as an explanatory variable depends on the type of model being used.
If a simple linear regression model is used, the model would have two parameters: the intercept and the slope coefficient for the ftmade variable.
If a multiple linear regression model is used, which includes more than one explanatory variable, the model would have additional parameters for each additional explanatory variable included.
For example, if the model also included the variables age and gender, the model would have four parameters: the intercept, the slope coefficient for ftmade, the slope coefficient for age, and the coefficient for gender (assuming gender is coded as a binary variable).

What is the perimeter of a rectangle with side lengths of 12in and 8in?
Answer:
40 inches.
Step-by-step explanation:
If you want to measure how much fence you need to enclose a rectangle, you have to add up the lengths of all its sides. That's called the perimeter. The easiest way to find it is to use this handy-dandy formula:
Perimeter = 2 (length + width) units
where length and width are how long the rectangle's sides are.
For example, let's say you have a rectangle that is 12 inches long and 8 inches wide. To find its perimeter, you just plug in those numbers into the formula:
Perimeter = 2 (12 + 8) inches
Perimeter = 2 (20) inches
Perimeter = 40 inches
Ta-da! The perimeter of the rectangle is 40 inches.
The Blackburn family has a square field where they keep their cattle. The area of the field is 40,000 ft square, and Mr. Blackburn wants to put a fence diagonally through the field. What should the length of the fence be?
If "square-field" area is 40000 ft square, and Mr. Blackburn is planning to put a fence diagonally in field, then the length of fence should be 282.84 ft.
The area of the Blackburn's square-field is = 40000 ft²,
First, we equate this with area formula,
On Equating ,
We get,
⇒ (side)² = 40000,
⇒ side = 200,
substituting the "side-length" of the field as 200 ft, in the diagonal of a square formula,
we get,
⇒ Length of field's diagonal is = (side)√2,
⇒ Length of field's diagonal is = (200)√2,
⇒ Length of field's diagonal is ≈ 282.84 ft.
Therefore, the length of field's fence is 282.84 ft.

three circular arcs of radius 5 units bound the region shown. arcs $ab$ and $ad$ are quarter-circles, and arc $bcd$ is a semicircle. what is the area, in square units, of the region?
The circular arcs of radius 5 units bound the region so the area, in square units, of the region is 50.
The simplest way to think about it is as follows. Assume we wish to define R as the entire region in the first quadrant above the graph y = x 2. S is now defined as the entire region below the graph of y = x. It is obvious that the region R S equals the area in the first quadrant below y = x minus the area under the curve y = x 2. Try to figure out why this is the case, and then click Continue.
Now that we know what kind of problem we're dealing with, we can start turning it to arithmetic, namely integrals. Take note that the region of interest goes between the two curve junctions.
The area of the semicircle is = [tex]\frac{1}{2} \pi 15^2[/tex]
= 25/2π
The area of the two quarter - circles is
= 2 x 1/4 x π x 25
= 25π/2

In a research study on trends in marriage and​ family, 2​% of randomly selected parents said that they never spank their children. The​ 95% confidence interval is from 1.2​% to 2.8​% ​(n=1241​).
a) Interpret the interval in this context
A. One is 95% confident that if one were to ask every parent, between 1.2% to 2.8% of them would say they never spank their children
B. There is a 95% chance that, if one were to ask every parent, 2% of them would say they never spank their children
C. There is a 95% chance that, if one were to ask overy parent, between 1.2% to 2.8% of them would say they never spank their children
D. One is 95% confident that of the 1236 parents polled between 12% 10 2.8% of them would say they never spank their children
The given information presents the results of a research study on trends in marriage and family, which indicates that 2% of randomly selected parents said they never spank their children.
The 95% confidence interval for this proportion is from 1.2% to 2.8%, based on a sample size of 1241.
A. One is 95% confident that if one were to ask every parent, between 1.2% to 2.8% of them would say they never spank their children.
The 95% confidence interval means that if we were to take many random samples of parents and construct a 95% confidence interval for each sample, then about 95% of those intervals would contain the true proportion of parents who never spank their children.
In other words, we can be 95% confident that the true proportion of parents who never spank their children is somewhere between 1.2% and 2.8%.
Option (C) is the correct interpretation of the interval in this context, which states that there is a 95% chance that, if one were to ask every parent, between 1.2% to 2.8% of them would say they never spank their children.
This implies that the true proportion of parents who never spank their children is likely to fall between 1.2% and 2.8%.
Option (A) is also a correct interpretation of the interval, as it implies that we are 95% confident that the proportion of parents who never spank their children falls between 1.2% and 2.8%.
Option (B) is incorrect because the 95% confidence interval refers to the range of possible values for the true proportion of parents who never spank their children, not the probability that a randomly selected parent would say they never spank their children.
Option (D) is incorrect because the sample size is 1241, not 1236.
In summary, the 95% confidence interval of 1.2% to 2.8% for the proportion of parents who never spank their children indicates that we are 95% confident that the true proportion of parents who never spank their children falls between these values, if we were to ask every parent.

Which composition of transformations maps figure efgh to figure efgh?.
To determine the composition of transformations that maps figure efgh to figure efgh, we need to first identify the transformations involved.
A transformation is a change in position, size, or shape of a figure. In this case, we can see that figure efgh has not changed in size or shape, so the transformation must involve a change in position.
One possible transformation that could be involved is a translation, which involves moving the figure along a straight line without changing its size or shape. Another possible transformation is a rotation, which involves turning the figure around a fixed point.
To find the composition of transformations that maps figure efgh to itself, we need to experiment with different combinations of translations and rotations until we find one that works. For example, we could first rotate the figure 90 degrees clockwise around its center, and then translate it 2 units to the right and 3 units up. This composition of transformations would move figure efgh to a new position, but still maintain its size and shape.
Alternatively, we could first translate the figure 2 units to the right and 3 units up, and then rotate it 90 degrees counterclockwise around its center. This would also result in a new position for the figure, but with the same size and shape as the original.
In conclusion, there are multiple compositions of transformations that could map figure efgh to itself, including combinations of translations and rotations. It is important to experiment with different options and test them to ensure that they maintain the size and shape of the figure.

5 black balls and 8 white balls are placed in an urn. two balls are then drawn in succession. what is the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball?
The probability of drawing a white ball on the second draw, without replacing the first ball, is 8/13.
To solve this problem, we need to use conditional probability.
The probability of drawing a white ball on the first draw is 8/13 (since there are 8 white balls and 13 total balls in the urn).
If a white ball is drawn on the first draw, then there will be 7 white balls and 5 black balls left in the urn. So the probability of drawing a white ball on the second draw, given that a white ball was drawn on the first draw, is 7/12.
If a black ball is drawn on the first draw, then there will be 8 white balls and 4 black balls left in the urn. So the probability of drawing a white ball on the second draw, given that a black ball was drawn on the first draw, is 8/12.
Now we can use the law of total probability to find the overall probability of drawing a white ball on the second draw:
P(white on second draw) = P(white on first draw) * P(white on second draw | white on first draw) + P(black on first draw) * P(white on second draw | black on first draw)
= (8/13) * (7/12) + (5/13) * (8/12)
= 56/156 + 40/156
= 96/156
= 8/13
Therefore, the probability of drawing a white ball on the second draw, without replacing the first ball, is 8/13.

When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

suppose that 5 fair coins are flipped randomly. compute the probability that one coin shows heads and the rest show tails. use three decimal place accuracy.
The probability of getting one head and the rest tails when flipping 5 fair coins is 0.156 or 15.6% to three decimal place accuracy.
To calculate the probability that one coin shows heads and the rest show tails, we need to use the formula:
P = (number of ways to get one head and four tails) / (total number of possible outcomes)
The total number of possible outcomes when flipping 5 coins is 2^5 = 32 (since each coin can either show heads or tails).
To calculate the number of ways to get one head and four tails, we can use the combination formula:
C(5,1) = 5
This means that there are 5 ways to choose which coin will show heads. Once we have chosen that coin, the other 4 coins must show tails. Since each coin has a 50/50 chance of showing heads or tails, the probability of this occurring is:
P = 5/32
Rounding to three decimal places, the probability is:
P = 0.156
Therefore, the probability of getting one head and four tails when flipping 5 fair coins randomly is 0.156 or 15.6%.

The value of angles in inscribed quadrilateral are μ(∠zyx) is 92⁰ and μ(∠yxw) is 65⁰.
An inscribed quadrilateral is a quadrilateral that can be inscribed in a circle, meaning that its vertices all lie on the circumference of a circle. In other words, the four vertices of an inscribed quadrilateral are concyclic.
The opposite angles of an inscribed quadrilateral are supplementary, which means that they add up to 180 degrees. This property is known as the "interior angle sum" of a quadrilateral.
μ(∠zyx) + μ(∠xwz) = 180⁰ (opposite angle of cyclic quadrilateral are supplementary)
μ(∠xwz) = 88⁰
μ(∠zyx) = 180⁰ - 88⁰ = 92⁰
μ(∠yzw) is an inscribed angle that intercepts the arc 112⁰ and 118⁰. Therefore,
μ(∠yzw)
= (112⁰ + 118⁰)/2
= 230⁰/2

SHOW WORK!!
The true statements in the rectangle DEFG are FHE = 60 and FEH = 60
Selecting all the true statements in the rectangle DEFGFrom the question, we have the following parameters that can be used in our computation:
The rectangle DEFG
On the rectangle DEFG, we have
1.5x + 8 = 3x + 2
Evaluate the like terms
So, we have
1.5x = 6
This gives
x = 4
Also, we have the following angle measures
FHE = 180 - 120
FHE = 60
Then, we have
FEH = FHE = 60
Hence, the the true statements in the rectangle DEFG are FHE = 60 and FEH = 60

a frog is placed at the origin on the number line, and moves according to the following rule: in a given move, the frog advances to either the closest point with a greater integer coordinate that is a multiple of , or to the closest point with a greater integer coordinate that is a multiple of . a move sequence is a sequence of coordinates which correspond to valid moves, beginning with , and ending with . for example, is a move sequence. how many move sequences are possible for the frog?
Therefore , Sequences that are possible for the frog are in number 4
1. First, let's identify the given multiples for the frog's movement. The frog can advance to either the closest point with a greater integer coordinate that is a multiple of 3, or to the closest point with a greater integer coordinate that is a multiple of 4.
2. The frog starts at the origin (0). The first possible moves are to 3 (multiple of 3) or to 4 (multiple of 4).
3. If the frog moves to 3, the next possible moves are to 4 (multiple of 4) or to 6 (multiple of 3). If the frog moves to 4, there are no more valid moves (the next multiple of 3 is 6, which is greater than 5).
4. If the frog moves from 3 to 4, the next possible move is to 6 (multiple of 3), and there are no more valid moves. If the frog moves from 3 to 6, there are no more valid moves.
5. Therefore, the possible move sequences are: (0, 3, 4, 6), (0, 3, 6), (0, 4), and (0, 3, 4).
So, there are 4 possible move sequences for the frog.

Geometric mean returns are: a simple averages of holding period returns. b expressed as compound rates of interest.c more applicable when no specific time interval is considered to be any more important than another. d widely used in statistical studies spanning very long periods of time.
The correct option is b expressed as compound rates of interest. Geometric mean returns are calculated by taking the nth root of the product of (1 + holding period return) for each period, where n is the number of periods.
The result is expressed as a compound rate of return, which reflects the compounding effect over time. Unlike arithmetic mean returns, which are simple averages of holding period returns, geometric mean returns give more weight to the returns in earlier periods and less weight to the returns in later periods. This makes geometric mean returns more applicable when no specific time interval is considered to be any more important than another.

a triangle is defined by the three points: . determine all three angles in the triangle (in radians).
To determine the three angles in a triangle, we can use the Law of Cosines or the Law of Sines. However, since we are not given any side lengths, we will use the dot product formula to find the angles between the sides.
Then, we can compute the magnitudes of these vectors using the Pythagorean theorem:
|AB| = sqrt((Bx - Ax)^2 + (By - Ay)^2)
|AC| = sqrt((Cx - Ax)^2 + (Cy - Ay)^2)
|BC| = sqrt((Cx - Bx)^2 + (Cy - By)^2)
where (Ax, Ay), (Bx, By), and (Cx, Cy) are the coordinates of points A, B, and C, respectively.
Finally, we can use the dot product formula above to compute the cosines of angles A, B, and C, and then take the inverse cosine to find the angles in radians:
A = acos((AB · AC) / (|AB| · |AC|))
B = acos((AB · BC) / (|AB| · |BC|))
C = acos((AC · BC) / (|AC| · |BC|))
where acos denotes the inverse cosine function.
Therefore, we can determine all three angles in the triangle (in radians) using the above formulae.
It seems that the three points of the triangle were not provided in your question. To help you determine the angles of the triangle, please provide the coordinates of the three points (A, B, and C).
