Step-by-step explanation:

the percent of the variability in y that can be explained by variability in the regression model  = 31% = 0.31

Formula : Percent of the variability = SSR/SST*100

, where  = Coefficient of Determination.

SSR =  sum of squares of regression

SST = total sum of squares

 is the proportion of the variation of Y that can be attributed to the variation of x.

As per given , we have

SSR = 3252.4

SST=  3961.2

Then, the percent of the variability in y that can be explained by variability in the regression model =SSR

Hence, the percent of the variability in y that can be explained by variability in the regression model  = 31%

The scale factor was used for each dilation are-

A transformation that changes the size of a figure is called a dilatation. This indicates that the preimage as well as image are similar and have been scaled up or down, respectively.

A dilatation that results in a reduction (imagine shrinking) or an enlargement (think stretching) produces a smaller or larger image, respectively.

Part a: For ΔABC

Length AB = 2 units

Length A'B' = 4 units

A'B' = 2 *AB

Thus,  For ΔABC - scale factor = 2

Part b: For ΔDEF -

Length DF = 2 units

Length D'F' = 1  units

D'F' = 1/2 DF

Thus, For ΔDEF - scale factor = 1/2

Part c: For ΔGHJ -

Length GH = 3 units

Length G'H' = 1  units

G'H' = 1/3 GH

Thus,  For ΔGHJ - scale factor = 1/3

Part d: For ΔKML -

Length KM = 2 units

Length K'M' = 6  units

K'M' = 3*KM

Thus, For ΔKML - scale factor = 3

Answer:

Let's assume the distances between the points G1, G2, and G3 and point A are d1, d2, and d3, respectively. Then, the moment produced by each weight around point A can be calculated as follows:

Moment of AB = 1700 lb x d1

Moment of BCD = 215 lb x d2

Moment of man = 164 lb x d3

The resultant moment produced by all the weights about point A can be found by adding up these individual moments:

Resultant moment about A = (1700 lb x d1) + (215 lb x d2) + (164 lb x d3)

To express the answer in appropriate units, we need to convert pounds (lb) to a standard unit of force such as newtons (N) and inches (in) to meters (m).

Assuming 1 lb = 4.44822 N and 1 in = 0.0254 m, we get:

1700 lb = 7585.74 N

215 lb = 957.5125 N

164 lb = 730.7096 N

1 in = 0.0254 m

Substituting these values into the above equation, we get:

Resultant moment about A = (7585.74 N x d1) + (957.5125 N x d2) + (730.7096 N x d3)

Answer:

$12.56

Step-by-step explanation:

$50.24 divided by the 4 friends = $12.56

I divided the total cost by the amount of friends who went to the museum and so I did $50.24 divided by the 4 friends = $12.56.

Each friend paid $12.56 for a ticket to the museum this was calculated by dividing the total cost of $50.24 by the number of friends, which is 4. So, they each paid an equal amount of $12.56.

To find out how much each friend paid for a ticket to the museum, we can divide the total amount they paid by the number of friends.

Given that there are 4 friends and the total cost is $50.24, we simply divide $50.24 by 4:

Amount each friend paid = Total cost / Number of friends

Amount each friend paid = $50.24 / 4

Calculating this division:

Amount each friend paid = $12.56

Therefore, each friend paid $12.56 for a ticket to the museum.

Answer:

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.

Step-by-step explanation:

The unit rates for both machines need to be calculated first.

The unit rate will be calculated as:

\(Unit\ rate = \frac{Area\ covered}{Time}\)

For Machine A:

Area Covered = 5/8

Time = 1/4

The unit rate will be:

\(U_A = \frac{\frac{5}{8} }{\frac{1}{4} } \\Using\ rule => \frac{\frac{a}{b} }{\frac{c}{d} } = \frac{a}{b} * \frac{d}{c}\\=\frac{5}{8} * 4 \\= \frac{5}{2} = 2.5\ square\ feet\ per\ hour\)

For Machine B:

Area Covered = 2/3

Time = 1/5

\(U_B = \frac{\frac{2}{3}}{\frac{1}{5}}\\= \frac{2}{3} * \frac{5}\\= \frac{10}{3}\\= 3.33...\ square\ feet\ per\ hour\)

As it can be seen that unit rate for Machine B is greater than Unit Rate of Machine A.

Hence,

Unit Rate of Machine A = 2.5 square feet per hour

Unit Rate of Machine B = 3.333 square feet per hour.

The unit rate of Machine B is greater than unit rate of machine A.

Answer:

(f - g)(x) = f(x) - g(g) = (3x + 1) - (x2 - 6) = -x^2 + 3x + 7

Step-by-step explanation:

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

                                            P = (-3.5, 1.25)

Hence, the coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25).

The solution to the equation 8(k - 1) = 9/2 is k = 1.6

The equation is given as:

8(k - 1) = 9/2

Start by dividing 9 by 2

8(k - 1) = 4.5

Divide both sides of the equation by 8

(k - 1) = 0.5625

Remove the bracket from the equation

k - 1 = 0.5625

Add 1 to both sides of the equation

k = 1.5625

Approximate the equation to the nearest tenth

k = 1.6

Hence, the solution to the equation 8(k - 1) = 9/2 is k = 1.6

The quadrilateral named D, H, and E will be the scaled copies of the unlabeled rectangle.

A quadrilateral may be defined as a closed figure having four sides whereas a rectangle is a type of quadrilateral which has four sides in which any two sides are equal and the other two sides are also equal. The interior angles are 90°. The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. Now, from the question If any figure is a scaled copy, then all dimensions must be enlarged with the same factor it means length and width both must be enlarged with the same factor. So, the unlabeled rectangle has 4 grid lengths and 2 grid widths. In H length is 8 grids and width are 4 which is the multiplication of 2 by 4 and 2. Quadrilateral D and E also follow the same.

I'd like to say it is a coincidence, or the data is biased in some way, but there is no way of telling without checking out the stats (which I would guess there are none).

Perhaps sharks like sugar and lot of someones drop their ice cream cones in the water. It's a test. Or it could be made into one.

Perhaps the sharks are annoyed by the ice cream and take it out on the person holding the ice cream. Again it's a test.

Perhaps they smell the ice cream and are attracted to it. I wouldn't want to test this with offering a shark a sugar cube put in water.
