Answer:

[tex]A = 34\frac{1}{3}[/tex]

[tex]B = 72\frac{2}{3}[/tex]

[tex]C = 73[/tex]

Step-by-step explanation:

Given

Shape: Triangle

[tex]B = 4 + 2A[/tex]

[tex]C = 3A - 30[/tex]

Required

Solve for A, B and C

Since the shape is a triangle,

[tex]A + B +C = 180[/tex]

Substitute [tex]B = 4 + 2A[/tex] and [tex]C = 3A - 30[/tex] in [tex]A + B +C = 180[/tex]

[tex]A + 4 + 2A + 3A - 30 = 180[/tex]

Collect Like Terms

[tex]A + 2A + 3A = 180 + 30 - 4[/tex]

[tex]6A = 206[/tex]

Solve for A

[tex]A = 206/6[/tex]

[tex]A = 34\frac{1}{3}[/tex]

Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]B = 4 + 2A[/tex]

[tex]B = 4 + 2 * 34\frac{1}{3}[/tex]

[tex]B = 4 + 2 * \frac{103}{3}[/tex]

[tex]B = 4 + \frac{206}{3}[/tex]

[tex]B = \frac{12 + 206}{3}[/tex]

[tex]B = \frac{218}{3}[/tex]

[tex]B = 72\frac{2}{3}[/tex]

Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]C = 3A - 30[/tex]

[tex]C = 3 * 34\frac{1}{3} - 30[/tex]

[tex]C = 3 * \frac{103}{3} - 30[/tex]

[tex]C = 103 - 30[/tex]

[tex]C = 73[/tex]

Answer:

Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg

Step-by-step explanation:

22.5 is 1/3 of 67.5

so compliment is 67.5.

Supplement is just adding another angle so I chose 7.

I did 22.5 x 7 = 157.5

Another example would be:

Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The sequence is nor properly written. This is correct sequence

49, 36, 25, 16, 9, 4, 1...

Merely looking at the sequence, we can see that it doesn't form an arithmetic sequence nor does it form a geometric sequence.

The values of the sequence are all perfect squares.

Rewriting the sequence;

7², 6², 5², 4², 3², 2², 1²...

Now we can see that the base values for an arithmetic sequence as shown:

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

We find the common difference of this sequence as shown

d = T2-T1 = T3-T2 = T4-T3

Given T1 = 7, T2 = 6, T3 = 5, T4 = 4

Substitute

d = 6-7 = 5-6 = 4-5 = -1

d = -1

Get the nth term using the sequence

Tn = a+(n-1)d

a is the first term

d is the common difference

n is number of terms

Tn = 7+(n-1)(-1)

Tn = 7+(-n+1)

Tn = 7+1-n

Tn = 8-n

Since their power are constant i.e squared, hence we will square the ntj term as well to get the nth term of the original sequence as;

Tn = (8-n)²

To conclude, we can say that the sequence is neither arithmetic nor geometric sequence since the terms of the sequence are prefect squares.

Answer: x = 13/2

Step-by-step explanation:

Distribute: 4(x - 2) = 18

4x - 8 = 18

Add 8 to both sides

4x - 8 + 8 = 18 + 8

Simplify:

4x = 26

Divide both sides of the equation by the same term

4x = 26

4x/4 and 26/4

Cancel term that are both in the numerator and denominator

Divide the numbers

X = 13/2

Answer:

Scale = ¼

Step-by-step explanation:

See attachment for complete question.

In the attached, we have.

Width = 4 units. ----- Orange

Width = 16 units ------- Black

Required

Determine the scale of dilation

The scale of dilation can be calculated as:

Scale = Width(orange)/Width (black)

Scale = 4/16

Scale = ¼

Hence, the scale of dilation is ¼

Answer:

[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x = \frac{1}{3} ( x - 1)\\\\ \\\frac{4}{3}x - \frac{4}{3} - \frac{2}{3} = \frac{4}{3} ( x - 1)\\\\( \frac{1}{3} x + \frac{2}{3} ) + ( -\frac{2}{3}x - \frac{4}{3}) = -\frac{1}{3} ( x + 2)\\\\(\frac{2}{3}x + \frac{1}{3} ) + (\frac{2}{3} x - \frac{2}{3} ) = \frac{1}{3} ( 4x - 1 )[/tex]

Step-by-step explanation:

Simplify each equation by combining like terms, and then factoring

[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x[/tex]

= [tex]\frac{1}{3} x + \frac{1}{3}[/tex]

= [tex]\frac{1}{3}[/tex] ( x + 1)

[tex]\frac{4}{3}x - \frac{4}{3} - \frac{2}{3}[/tex]

= [tex]\frac{4}{3}x - \frac{6}{3}[/tex]

= [tex]\frac{4}{3}[/tex] ( x - 1 )

Answer:  see below

Step-by-step explanation:

I'm not sure exactly what you are asking for but here is what the box plot tells you:

Minimum is 17 items.

Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.

Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.

Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.

Maximum is 62 items.

The data is "heavier" on the right so it is skewed left.

Range is 62 - 17 = 45

IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13

Answer:

x = 5 + 5y/4

Step-by-step explanation:

I think its like this: 4x - 5y = 20

Add 5y to both sides: 4x = 20 + 5y

Divide both sides by 4: x = 20/4 + 5y/4

Simplify: x = 5 + 5y/4

I'm pretty sure it is like this

Expectation is equal to 4.75

Variance is equal to 3.02

Step-by-step explanation:

Consider the attached image.

Let [tex]x_i[/tex] denotes each of the outcome.

Expectation [tex]=E(X)[/tex] = ∑[tex]x_if(x_i)[/tex]

[tex]=1(\frac{1}{12}) +2(\frac{1}{12}) +3(\frac{1}{12}) +4(\frac{1}{12}) +5(\frac{1}{12}) +6(\frac{7}{12})[/tex]

[tex]E(X^2)=[/tex] ∑ [tex]x_i^2f(x_i)[/tex]

[tex]=1^2(\frac{1}{12}) +2^2(\frac{1}{12}) +3^2(\frac{1}{12}) +4^2(\frac{1}{12}) +5^2(\frac{1}{12}) +6^2(\frac{7}{12})[/tex]

Answer:

55.25

Step-by-step explanation:

85 X 0.35 = 29.75

85 - 29.75 = 55.25

Answer: 29.75

My Explanation:

85 divided by 10 = 8.5 (10%)

8.5 x 4 = 34.0 (40%)

8.5 divided by 2 = 4.25 (5%)

34 - 4.25 = 29.75 (35!)
