Answer:

the first one is the answer

Answer:

3 decimal 75 is the answer

Answer:

(2, -1)

Step-by-step explanation:

First off, we need to find the coordinates of D. We do this by applying the partitioning formula. It is (m/m+n)(x2-x1) +x1 for x and (m/m+n)(y2-y1)+y1 for y. The value of m is 5 and n is 3. You would need to input the valuables in. This will create (5/8)(10-2)+2 for x and (5/8)(2-(-6))-6 for y. In the end, we will have 7 for x and  -1 for y. To find c we just need to find what coordinates follow the x axis and for what y. We see that C follows the x coordinates of point A and y coordinates follow point D.

Answer:

median: 51

mode: 51

Explanation:

given:

43, 55, 51, 62, 64, 38, 35, 45, 51

arrange them in increasing order:

35, 38, 43, 45, 51, 51, 55, 62, 64

now find median, the number which is at the middle:

51 is the median

now find the mode, the number which appears most times:

51 is the mode

Answer:

C

Step-by-step explanation:

I also see median right there which that would also be C(51)

The mode is C(51) because the mode is the number that appears the most and as you see 51 appears 2 while no other number appears twice.

Hope this helps have a great day:)

Greatest Common Factor

- first list all the numbers that could be multiplied to the factors given.

30 = 1, 2, 3, 5, 6, 10, 15, & 30

24 = 1, 2, 3, 4, 6, 8, 12 & 24

- then you find the common number between them but the highest one (which is 6)

Least Common Multiple

- so we could say this is the opposite of the greatest common factor

3 = 3, 6, 9, 12, 15, 18

4 = 4, 8, 12, 16, 20

- in here i listed the multiples of 4 & 3 and got the least common between them (which is 12)

Answer:

tbf i wouldnt get this if i read this for the first time

Step-by-step explanation:

write numbers down

draw a branch to split the number into a prime and the number it needs to multiply to get to it

e.g. 156 can split into

/ \

2 78

kee.p splitting the number.s

78 = 2, 39

39 = 3, 13

now do the same for the second number

e.g. 188

/ \

2 94

94 = 2, 47

draw a venn diagram

put the numbe.rs in the correct locatio.n

a repe.at number e.g. 2, 2, 2, 2 now wo.uld be two 2s because they essential.ly cancel each other out

156 188

13, 3 2, 2 47

for gcf you would times the number in the centre

2 x 2 = 4

4 is the gcf

for lcm you would times everything in the venn diagram

13 x 3 x 2 x 2 x 47 = 7332

7332 is lcm

Step-by-step explanation:

Find the GCF of 15 and 6:

15: 1, 3, 5, 15

6: 1, 2, 3, 6

The GCF is 3.

Distribute out 3 in 15 and 6:

In other words, divide 15 and 6 by 3.

The sound waves are illustrations of cosine functions

The frequencies of the sound waves are x = 90°, 120°, 240°, 270°

The equations of the sound waves are given as:

[tex]y = 2\cos^2(x)[/tex]

[tex]y =-\cos(x)[/tex]

Next, we plot the graphs of the functions [tex]y = 2\cos^2(x)[/tex] and [tex]y =-\cos(x)[/tex]

From the graphs of the functions (see attachment), we have the following x-coordinates of the points of intersection of the both curves between the interval [0°, 360°)

[tex]x =(\frac{\pi}{2},\frac{2\pi}{3},\frac{4\pi}{3},\frac{3\pi}{2})[/tex]

Express as degrees

[tex]x =(90^o,120^o, 240^o, 270^o)[/tex]

Hence, the frequencies of the sound waves are x = 90°, 120°, 240°, 270°

y = 3/5x - 1

Step-by-step explanation:

The slope found from counting the units is 3/5, and the y-intercept is -1, hence 3/5x - 1

Answer:

-i

Explanation:

Just divide that power by 4

99/4 you get 24.75

multiply the whole part 24 by 4

and then multiply 0.75 by 4

In the end, you get

[tex](i^{4})^{24}*i^{3}[/tex]

[tex]i^{4} = 1[/tex]

[tex]i^{3} = -i[/tex]

Answer:

Step-by-step explanation:

6x+y = 4x+11y, isolate y terms on one side and x terms on another side by subtract 11y to both sides and subtract 6x to both sides

y -11y = 4x -6x, combine like terms

 -10y = -2x , divide both sides by -10

      y = (-2/-10)x, simplify the fraction

      y = (1/5) x

Answer:

quotinet = 3x² - 2x - 2

remainder = 7

Step-by-step explanation:

12x³ - 2x² - 12x + 3

= 3x²(4x + 2) - 6x² - 2x² - 12x + 3

= 3x²(4x + 2) - 8x² - 12x + 3

= 3x²(4x + 2) - 2x(4x + 2) + 4x - 12x + 3

= 3x²(4x + 2) - 2x(4x + 2) - 8x + 3

= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 4 + 3

= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 7

= (4x + 2)(3x² - 2x - 2) + 7

so

quotinet = 3x² - 2x - 2

remainder = 7

Hello!

For this uniform distribution, the shape of the density function is a line. We can begin by identifying key elements of the distribution:

Range: 6 to 14 pounds

Formula of density function:

y = 1/Range

1 - (14 - 6) = 1/8 = 0.125

f(x) = 0.125

1)

P(x = 7)

A uniform distribution is a continuous distribution, so the probability of x being an EXACT value is approximately 0.

This is the same as if we took the following integral. (Finding the area under a curve with the same start and end point)
[tex]\int\limits^a_a {f(x)} \, dx = 0[/tex]

Therefore, P(x = 7) = 0.

2)
We can think of this as finding the area of a rectangle.

The width would be the difference between 8.25 pounds and 12 pounds:
W = 12 - 8.25 = 3.75

The height would be the function (y = .125), or:
h = .125

Using the equation for the area of a rectangle: (A = h * w)

A = 3.75 * .125 = 0.469

Thus, P(8.25 < x < 12) = 0.469

3)
To find the probability GREATER than 10.50 pounds, we can subtract this value from the max value for the width:
W = 14 - 10.50 = 3.50

The height is the same as above:
h = .125

Solve for the area:
A = 3.50 * .125 = 0.4375

P(x > 10.5) = 0.4375

[tex]y=2x+3[/tex]

Step-by-step explanation:

Choose 2 ordered pairs from the table:  (0, 3) and (5, 13)

Let [tex](x_1,y_1)[/tex] = (0, 3)

Let [tex](x_2,y_2)[/tex] = (5, 13)

Use the slope formula to find slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\implies m=\dfrac{13-3}{5-0}=2[/tex]

Use point-slope form of linear equation to find equation:

The volume of the container is 2,452,864 cubic feet.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism.

We know that the container can hold 896 wooden cube blocks, each with an edge length of 14 ft.

This means that the total volume of the wooden blocks is:

V(block) = (14 ft)³ = 2,744 ft^3

To find the volume of the container, we need to divide the total volume of the wooden blocks by the number of blocks that can fit in the container.

We are told that the container can hold 896 wooden blocks, so we can set up the following equation:

V(container) / V(block) = 896

Solving for V(container):

V(container) = V(block) x 896

V(container) = 2,744 ft³ x 896

V(container) = 2,452,864 ft³

Therefore,

The volume of the container is 2,452,864 cubic feet.
