which of the following best describes the shape of the slice of pizza shown in the figure?​

Answer:

Option B. Quadratic

Step-by-step explanation:

In a regression model, the value of [tex]r ^ 2[/tex] tells us how accurately the model fits the data.

That closer the value of [tex]r ^ 2[/tex] of 1 is,  better is the model.

This can be used to compare what type of model is most convenient to use in some cases.

In this problem the attached table shows a comparison of the value of [tex]r ^ 2[/tex] for 3 models

Linear

Quadratic

Exponential

Note that the value of [tex]r ^ 2[/tex] that is closest to 1 is that which corresponds to the quadratic model.

[tex]r ^ 2 = 0.89[/tex]

Therefore the function that best fits the points is the quadratic

Answer:

[tex]\dfrac{9}{64}[/tex]

Step-by-step explanation:

There are 12 face cards in a deck of standard playing cards and 20 even numbered cards, in total 32 cards.

1. The probabilty that the first drawn card is face card is

[tex]p_1=\dfrac{12}{32}=\dfrac{3}{8}.[/tex]

2. The probabilty that the second drawn card is an even numbered card (even numbered cards are 6, 8, 10 - 12 in total, odd numbered cards are 7, 9 - 8 in total) is

[tex]p_2=\dfrac{12}{32}=\dfrac{3}{8}.[/tex]

3. The probability that the first drawn card is a face card and the second drawn card is an even numbered card is

[tex]p_1\cdot p_2=\dfrac{3}{8}\cdot \dfrac{3}{8}=\dfrac{9}{64}.[/tex]

Answer:

4/15

Step-by-step explanation:

There are red, green and blue marbles in the bag.  The total of all the probabilities of selecting red, green and blue marbles is 1.00, or just 1.

So, to find the probability of selecting a blue marble, we add together 1/3 and 2/5 and subtract the total from 1:

1 - (1/3 + 2/5)

or:

1 - (5/15 + 6/15)

or:

1 - 11/15, or 4/15 (answer)

Final answer:

The probability of selecting a blue marble from the bag, given that reds have a probability of 1/3 and greens 2/5, is 4/15.

Explanation:

To find the probability of selecting a blue marble, you need to subtract the probability of selecting either a red or a green marble from 1, since the total probability must equal 1.

You are given that the probability of selecting a red marble is 1/3, and the probability of selecting a green marble is 2/5. To find the probability of selecting a blue marble, you can use the formula:

Probability of blue marble = 1 - (Probability of red marble + Probability of green marble).

Substituting the given probabilities, we get:

Probability of blue marble = 1 - (1/3 + 2/5)

Firstly, find a common denominator for the fractions, which is 15.

Probability of blue marble = 1 - (5/15 + 6/15)

Probability of blue marble = 1 - 11/15

Probability of blue marble = 15/15 - 11/15

Probability of blue marble = 4/15. Hence, the probability of selecting a blue marble is 4/15.

Answer:

1/8.

Step-by-step explanation:

The probability of of a head (and a tail) in one toss of a coin  being obtained is 1/2.

Each toss is independent of the others so we multiply the probabilities.

So Prob(Head - tail - head) = 1/2*1/2*1/2 = 1/8.

Answer:

1/8.

Step-by-step explanation:

It’ll be (5,4) because it’s on the same Y line (aka 4) just like (1,2) and (5,2).

The coordinates of the fourth vertex of the rectangle are (5, 4).

A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.

Given that, three vertices of a rectangle are located at (1,4), (1,2), and (5,2).

The intersection point of diagonals of rectangle is midpoint of each diagonal.

Let the fourth coordinate be (x, y). By the above property we get

Now, the midpoint of (1, 4) and (5, 2) is

[(1+5)/2, (4+2)/2] =(3, 3)

Thus, (3, 3) =[(x+1)/2, (y+2)/2]

3=(x+1)/2, 3=(y+2)/2

6=x+1, 6=y+2

x=5, y=4

Therefore, the coordinates of the fourth vertex of the rectangle are (5, 4).

The root of the polynomial is 3

Step-by-step explanation:

To find the root of the polynomial x(x-2)(x+3)=18

We can use a graphing utility and the system of equations.

We can have the equations;

y = x(x-2)(x+3) ......(i)

Therefore, from the initial equation;

y = 18 ..................... (ii)

We can then plot the graph using the equations, and the x-coordinate of the point of intersection will be the root of the equation.

From the graph, the x-coordinate is 3, since the intersection point is (3,18).

Therefore; the root of the equation is 3.

Row A:   x = 3

y = 2x - 3

y = 2(3) - 3 = 3      This is correct

Row B: x = 5

y = 2x - 3

y = 2(5) - 3 = 7        This is correct

Row C: x = 7

y = 2x - 3

y = 2(7) - 3 = 11      this is correct

Row D: x = 10

y = 2x - 3

y = 2(10) - 3 = 17  THIS IS INCORRECT, SO ROW D

Answer:

Road D

Answer:

She started with 26 boxes.

Step-by-step explanation:

She started with x boxes. Then she bought 8 more boxes. Now she had x + 8 boxes. Then half the boxes were destroyed, so she has the other half of the boxes. Half of the boxes is (x + 8)/2. She has now 17 boxes, so (x + 8)/2 = 17.

(x + 8)/2 = 17

Multiply both sides by 2.

x + 8 = 34

Subtract 8 from both sides.

x = 26

She started with 26 boxes.

EXPLANATION

[tex] {x}^{4} + 3 {x}^{2} + 2 = 0[/tex]

[tex]{ ({x}^{2}) }^{2} + 3( {x}^{2}) + 2 = 0[/tex]

Let

[tex]u = {x}^{2} [/tex]

Then the equation becomes:

[tex] {u}^{2} + 3u + 2 = 0[/tex]

[tex] {u}^{2} + 3u + 2 = 0[/tex]

[tex] {u}^{2} + 2u +u + 2 = 0[/tex]

Factor:

[tex]{u}(u + 2)+ 1(u + 2) = 0[/tex]

[tex](u + 1)(u + 2) = 0[/tex]

[tex]u = - 1[/tex]

or

[tex]u = - 2[/tex]

This implies that

[tex] {x}^{2} = - 1 \implies \: x = \pm \: i[/tex]

or

[tex] {x}^{2} = - 2 \implies \: x = \pm \: \sqrt{2} i[/tex]

You can set up a proportion based on the information you know. There are several ways to do this but here's one: [tex]\frac{8}{4} = \frac{s}{16}[/tex] because the 8 corresponds to the 4 and the s correspnds to the 16. Cross multiply to get 8 * 16 = 4s → 128 = 4s → 32 = s so the value of s is 32m

The value of s is 32 m.

Similar trapezoids are trapezoids whose sides are in a ratio. the ratio is known as the scaled factor.

A scale factor is a factor by which the image is been enlarged. for example, the scale factor of 10 means each side will be multiplied by 10, resulting in a figure that is 10 times the real figure.

As given to us, ABCD is similar to trapezoid EFGH. therefore, the sides of the trapezoid are in a ratio.

Thus we can write,

[tex]\bold{\dfrac{EH}{AD}=\dfrac{GH}{CD}}[/tex]

substituting the values we get,

[tex]\bold{\dfrac{s}{16}=\dfrac{8}{4}}[/tex]

[tex]\bold{s=\dfrac{8\times 16}{4}=32}[/tex]

Answer:

4(a + b)^2

p = 6/5 or 1.2

Step-by-step explanation:

Question One

z = a^2 + b^2

y = ab

4z = 4*a^2 + 4*b^2

8y = 8*ab

=================

4z + 8y = 4a^2 + 8ab + 4b^2

4z + 8y = 4(a^2 + 2ab + b^2)

4z + 8y = 4(a + b)^2

Question Two

2(p + 1) + 8(p - 1) = 5p

2p + 2 + 8p - 8 = 5p

2p + 8p + 2 - 8 = 5p

10*p - 6 = 5p

10*p = 5p + 6

10p - 5p = 6

5p = 6

Answer:

108

Step-by-step explanation:

36÷4= 9

9 is the unit rate

5×9=45

Natasha has 45 sweets

3×9= 27

Richard has 27 sweets

36+ 45+ 27= 108

All together they have 108 sweets

In total, there are 108 sweets. This answer is derived by finding the value of one part of the ratio and then multiplying this by the sum of all parts of the ratio.

The question is about the distribution of sweets among Sarah, Natasha and Richard in the ratio 4:5:3. You have been given that Sarah, represented by the first term of the ratio, gets 36 sweets. To find how many sweets there are altogether, we first need to determine the value of one part of the ratio.

In this case, if 4 parts are equivalent to 36 sweets, then one part is equivalent to 36 divided by 4 which equals 9 sweets.

Now, to find the total sweets, we need to sum all parts of the ratio which is 4 parts for Sarah, 5 parts for Natasha and 3 parts for Richard. Total parts = 4 + 5 + 3 = 12. This total is then multiplied by the value of one part of the ratio. Here, total sweets = 12 parts * 9 sweets = 108 sweets.

In the commutative property, order does not matter for addition and multiplication. However, this is not true when it comes to subtraction and division problems, where order does matter.

The commutative property states that:

a + b = b + a (addition)

a × b = b × a (multiplication)

However, this does not apply to:

a - b ≠ b - a (subtraction)

a ÷ b ≠ b ÷ a (division)

In subtraction and division, the order of the operands matters, and changing the order can result in different values.
