Answer 1

Answer:
x=103 degrees
y=113 degrees

Explanation:
All the angles in a triangle add up to 180 degrees, so to find the measurement of angle x, we can use this equation and solve:

x=180-23-54
x=180-77
x=103

To find angle y, we need to understand that a straight line also has an angle of 180 degrees. This means we need to subtract the angle that is next to angle y from 180 to get angle y.

However, to find that angle that is next to angle y, we need to do the same thing we did above and find the angles of the triangle.

First, we find the angle next to x using this expression:

180-x
=180-103
=77

And now we find the measurement of the angle next to angle y:

180-77-36
=103-36
=67

And now we find angle y:

180-67
=113

Therefore, y=113 degrees

Answer:

Therefore, x = 23°, ∠LKM = 56° and ∠MKN = 89° .

Step-by-step explanation:

Given that ∠LKN is 145° so we can assume that ∠LKM addes together with ∠MKN will get 145° in terms of x :

[tex]∠lkn = ∠lkm + ∠mkn = 145[/tex]

[tex]2x + 10 + 4x - 3 = 145[/tex]

[tex]6x + 7 = 145[/tex]

[tex]6x = 145 - 7[/tex]

[tex]6x = 138[/tex]

[tex]x = 138 \div 6 = 23[/tex]

Next, we have to substitute x = 23° into the expressions of ∠LKM and ∠MKN :

[tex]∠lkm = 2(23) + 10 = 56[/tex]

[tex]∠mkn = 4(23) - 3 = 89[/tex]

Write an equation in point-slope form. Crossing the x-axis at x = -3 and the y-axis at y = 6

Answers

Answer:

y = 2x + 6

Step-by-step explanation:

The equation for a linear line is y = mx + c.

We know we want it to cross the y-axis at 6, so the y-intercept (c) can be assumed to be 6.

If we substitute in the x that we want, we end up with this:

0 = m(-3) + 6

m = 2

So now we can form the equation:

y = 2x + 6

x = 8

Step-by-step explanation:

Step 1: Write equation

5x - 11 = 3x + 5

Step 2: Solve for x

Subtract 3x on both sides: 2x - 11 = 5

Add 11 to both sides: 2x = 16

Divide both sides by 2: x = 8

Step 3: Check

Plug in x to verify it is a solution.

x2 + 11x = 30

Answers

Answer:

x2 - 11x = -30

x^2 - 11x = -30

add 30 to the left to make it = to zero

x^2 - 11x + 30 = 0

factor

(x-5)(x-6) = 0

check by FOIL

x times x = x^2

x times -6 = -6x

x times -5 = -5x

-6 + -5 = 11x

-5 times -6 = 30

x2-11=-30

results.
***data set in picture attached***

Answers

Answer:

a) Coefficient of Variation for Height = 4.46%

b) Coefficient of Variation for Ages

= 12.26%

c)Comparing both Variations, the coefficient of variation for ages is larger than that of the mean and this is due to the fact that the

Step-by-step explanation:

Coefficient of Variation formula = Standard deviation / Mean × 100%

From the attached diagram, we are given sample data

1) For the Height

a) Mean of the Heights

= Sum of term/ Number of terms

= 74 + 70 + 70 + 76 + 77 + 72 + 75+ 70 + 70 + 80 + 75 + 75/12

= 884/12

= 73.66666667

b) Standard Deviation of Heights

For Sample data, the formula

=√ (X - Mean)²/n - 1

= 3.284490644

c) Coefficient of variation for Heights

Coefficient of Variation formula = Standard deviation / Mean × 100%

=( 3.284490644/73.66666667) × 100

= 0.04458584584 × 100

= 4.45858458441%

≈ 4.46%

2) Mean of ages

= Sum of terms/ Number of terms

= 21 + 26 + 22 + 27 + 29 + 26 + 27 + 29 + 30 + 31 + 31 + 31/12

= 330/12

= 27.5

b)Standard Deviation of Ages

For Sample data, the formula

=√ (X - Mean)²/n - 1

= √ (21 - 27.5)² + (26- 27.5)² +( 22- 27.5)² + (27- 27.5)² + (29- 27.5)² +( 26- 27.5)² +( 27- 27.5)² + (29- 27.5)² + (30 - 27.5)² + (31- 27.5)² + (31- 27.5)²+ (31- 27.5)²/12

=√ -6.5² + -1.5² + -5.5²+ -0.5² + 1.5² + -1.5² + -0.5² + 1.5² + 2.5² +3.5² + 3.5² + 3.5²/ 11

= √125/11

= √11.36363636

= 3.370999312

c) Coefficient of Variation

= Coefficient of Variation formula = Standard deviation / Mean × 100%

= (3.370999312/27.5) × 100

= 0.12258179316 × 100

= 12.258179316%

It should be noted that the coefficient of variation for height will be 4.46%.

How to calculate the coefficient of variation

The Coefficient of Variation formula will be:

= Standard deviation / Mean × 100%

The mean of the heights will be:

= Sum of term/ Number of terms

= 74 + 70 + 70 + 76 + 77 + 72 + 75+ 70 + 70 + 80 + 75 + 75/12

= 884/12

= 73.7

The standard deviation of heights is 3.28. Therefore, the coefficient of variation for heights will be:

= ( 3.28/73.7) × 100

= 4.46%

The mean of ages will be:

= 21 + 26 + 22 + 27 + 29 + 26 + 27 + 29 + 30 + 31 + 31 + 31/12

= 330/12

= 27.5

The standard deviation of ages is 3.37. Therefore, the coefficient of variation will be:

= (3.37/27.5) × 100

= 0.123 × 100

= 12.3%

In conclusion, the coefficient of variation for ages is larger than that of the mean.
