I tried my best!!

The volume of the trapezoidal prism comes to be 312 cubic units.

The volume of a prism is the product of the base area and its height.

So, the volume of the given prism = area of trapezoidal base * height

Area of the trapezoidal base = 0.5 * (sum of parallel sides) * distance between parallel sides.

Area of the trapezoidal base =0.5 * (8+5) * 4

Area of the trapezoidal base =26 square unit

So, the volume of the given prism = 26*12 = 312 cubic units.

Hence, the volume of the trapezoidal prism comes to be 312 cubic units.

Answer:

-4

Step-by-step explanation:

Answer:

According to the numbers provided, the sequence is:

5, 6, 1, 4, 7, 3, 2

Solution of the two lines intersecting in the graph is answer B

The inequality that represents the graph is that of answer A

Step-by-step explanation:

First problem:

This is the sequence to solve for "x" once the substitution was made;

[tex]3x +2\,(x+3)=11\\3x+2x+6=11\\5x+6=11\\5x=11-6\\5x=5\\x=1\\[/tex]

Now that we know x, we use its value (1) in the substitution equation in order to find "y" and complete the ordered pair:

[tex]y=x+3\\y=1+3\\y=4[/tex]

Then the solution pair (x, y) is: (1, 4)

Therefore, according to the numbers provided in the list of possible steps, the order is:

5, 6, 1, 4, 7, 3, 2

Second problem:

The solution to the system is where the two lines two lines intersect: "the point -1.5 on the x axis. Notice that -1.5 can be written in fraction form as -3/2, this is the x-coordinate of the intersection point. The y-coordinate is y-0 since the point is on the x-axis. Therefore the point is (-3/2, 0) which is given by answer B).

Third problem: The boundary line seems to go through the points: (-4, -10) and (0, -2), so we can calculate the slope via the equation:

[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-2-(-10)}{0-(-4)}\\slope=\frac{8}{4}\\slope=2[/tex]

since the line's y-intercept is (0, -2), then the equation of the boundary line in slope-intercept is:

[tex]y=2x-2[/tex]

Since the shaded region includes the boundary line and the zone above it (with y-values larger than or equal to those point in the line), we can say that the inequality that represents this graph is:

[tex]y\geq 2x-2[/tex]

which corresponds to answer A

Answer:

C. 5 times the MAD

Step-by-step explanation:

The difference between the mean cost to treat dogs at No Ruff Stuff Animal Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is about 5 times the MAD. This is a large difference.

The correct option is C.

In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).

Given:

The mean cost to treat dogs at No Ruff Stuff Animal Hospital is $224.65.

And MAD = $20.52

The mean cost to treat cats at No Ruff Stuff Animal Hospital is $124.84.

And MAD = 19.75.

The difference between the mean cost to treat dogs at No Ruff Stuff Animal

Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is,

= 224.65 - 124.84.

= 99.81

= 5 x 19.75

Therefore, the difference is 5 times MAD.

#SPJ6

Answer:

C. 3.4

Step-by-step explanation:

We need to find expected value, which is essentially the value that we expect to get based on the amount of each "thing" at hand.

Here, we have 4 multiple-choice questions worth 3 points each and 2 true/false questions worth 1 point each. Each multiple-choice question has 5 possible answers, so the probability that you get that multiple-choice question correct is 1/5. Similarly, each true/false question has 2 possible answers, so the probability that you get that question right is 1/2.

Expected value, denoted by E(x), has the formula:

E(x) = ∑ xp(x), where x is the number of points you get per problem here and p(x) is the probability of getting the problem correct

E(x) = 4 * 3 * (1/5) + 2 * 1 * (1/2) = 12/5 + 1 = 17/5 = 3.4.

The answer is thus C.

Answer:

For tree see picture but instead of BG replace all values with RRBBB and see the notes above how to roate the colours instead of the shape roation below just do transition (0,0)(1,0) (1,1).

Then 13 colours minimum change.

This will be 3 + 5 + 4 each colour change = 12 each colour change. instead of doing the 56 each colour rotation below.

Step-by-step explanation:

make 4 bits of paper and label each side -1 and 1 and central 0

above central point vertically label 1 and -1 for transition.

Then change just top one 4x = 4 more

Do the same with 2nd from top = 8 more to include top changing 4x again.

Do the same with 2nd from bottom = 12 more

Do the same with bottom = 16 more.

4+8+12+16 =40

Then repeat the process on side for blocks and we can double up

40+40 = 80.

When drawing tree clearly state columns

Top two are red only change

Top of tree will read in order so where ever you see capital R you will know its a new column for the tree and fill in when you understand the 254 transitions of a 5 column tree. Then change B + R accordingly when you get to row 6. Here you just start changing blue back to the top after row 5

Columns go down and rows go across its a new row you will need

approx 5-6 rows each colour change.

For the ones started for you below its just transition and colour stays where it is.  

R x    RT 45d   RT (1,0) 45   RT (1,1) 45  RT (1,0)

R x    R x

B x    B x

B x    B x

B x    B x

'x' = RED Normal as you keep 0 zero central on all 4 bricks and work with top row as explained below.

Top RED  brick you have to Right side place transition on every 2nd column for each colour and thenyou should find a pattern if youve numbered your papers or brcks to just see how it works. (hanging out one side call this 'off set' or call it T for transition (1.0)

RED Central 'diagonal' call it  '45 degree rotate'

E ABCD RED Normal edge transition its edge so it hangs out

E ABCD RED On edge 45 degree diagonal its edge so it hangs out

2nd only change

S ABCD 1st red normal 2nd red Right side place rotate

S ABCD 1st red right side rotate 2nd red 45 degree rotate

S ABCD 1st red right side rotate 2nd central place 45 degree rotate  

S ABCD 1st red right side rotate 2nd edge Normal edge transition

S ABCD 1st red right side rotate 2nd 45 degree its edge diagonal

2nd is repeated by changing 1st 4x more in bold. see what is now missing for 1st red. and copy the 2nd changes to 1st all whilst rotaing 2nd again in change .

Copy paste the work

Then apply this to 3 + 4 + 5th brick.

As the above shows 10 and when you finish 2nd and 1st it will be 14 total

Then 3 will be 14 again

and 4th brick will be 14 again

and 5th brick will be 14 again

making the transitions and rotations where all bricks in same level placement

14 x 4 = 56 transitions/rotations

Then repeat again for 1 blue at the top change

Then repeat again for 2 blue at the top for change

Then repeat again for 2 blue in the top middle

Then repeat again for 2 blue in the bottom middle

You can label tree

RR = Red rotation

BR = Blue rotation

RRE= Red rotation edge

BRE = Blue rotation

and colour code blue and red pens.

You can label transitions

RT = red transition (1,0)

RT = red transition (1,1) for central

and same for blue etc..

The end result will be 56 x 4 = 224 diagram tree

Answer:

If 6 apples cost $1.98 then 20 apples cost

Step-by-step explanation:

First you want to find the unit rate so divide both numbers

so the answer is 3

Answer:

$6.60

Step-by-step explanation:

6 apples=$1.98

So, 6 times 3= 18 apples

That means you also have too multiply the price by 3 and 1.98 times 3=5.94

now you have 18 of the 20 apples

for the last two, simply divide 1.98 by three which= $.66

then add $.66 to $5.94 and get $6.60

Answer:

D

Step-by-step explanation:

plato

The equation of this graph would be (x − 5)^2 = -8(y + 4). So option D is correct.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point then for some polynomial functions, we have those as roots of the polynomial.

Hence,  the equation of this graph would be (x − 5)^2 = -8(y + 4).

So option D is correct.
