Find the z value to the right of the mean so that 69.85% of the area under the distribution curve lies to the left of it.

Please explain!

Answer:

The set of numbers a = 3, b = 6, and c = 9 proves the hypothesis because 3 is a factor of 6 and 3 is a factor of 9. Property 1 states that therefore 3 is a factor of 9 + 3 =12, which we know is true because 3 × 4=12. You can prove that this property is true for all integers if you know what the term factor means.

Answer:

64.4

Step-by-step explanation:

In one of the trig formulas, it states    sin <a/A = sin<b/B = sin<c/C

So we have in this case:

sin(70)/12 = sin x/14           Note: x is just a variable for the angle <ABC

14(sin70)/12 = sin x

sin^-1(14(sin70)/12) = x

x=64.4

Answer:

x = 100°

Explanation:

The polygon has 6 sides, meaning it's a hexagon. In the picture you can see the following steps under #1:

(6-2) x 180° = 4 x 180 = 720°

720 is the total amount that all the angles should add up to, including the missing number x.

To solve for x add all of the angles up:

120 + 156 + 145 + (x + 9) + x + 90 = 720

520 + 2x = 720 (subtract 520 from both sides)

                 -520

          2x = 200 (divide 200 by 2 to have x on its own)

             x = 100°

To make sure it's correct, plug in the value (100°) for x in the original equation to check the answer:

120 + 156 + 145 + 100 + 9 + 100 + 90 = 720

720 = 720 Correct

Step-by-step explanation:

You and four friends = 5 people

To see how much one ticket costs we have to divide the total amount spent by the number of people who bought tickets.

Total amount spent: $110

People who bought tickets:5

110÷5=22

Each ticket cost $22

Answer:

$110÷5

=$22

therefore each ticket costs $22

[tex]x=\frac{83}{8}\text{ or}\ 10.375[/tex]

Step-by-step explanation:

Start by combining like terms:

[tex]5x+3x=83[/tex]

[tex]8x=83[/tex]

Divide both sides by 8

[tex]x=\frac{83}{8}[/tex]

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )

5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides

5x + 5 = 3x + 9 ( subtract 3x from both sides )

2x + 5 = 9 ( subtract 5 from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

The domain of the function shown in the graph are all real numbers. Therefore, option C is the correct answer.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.

The coordinate points from the given graph are (-2, 0) and (10, 6).

Here, slope m=(6-0)/(10+2)

= 6/12

= 1/2

= 0.5

Substitute m=0.5 and (x, y)=(-2, 0) in y=mx+c, we get

0=0.5(-2)+c

0=-1+c

c=1

So, equation of a line is y=0.5x+1

Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Therefore, option C is the correct answer.

Answer:

[tex]\displaystyle [0, 8][/tex]

Explanation:

This is an automatic give-away. If you look clocer, you will see that both equations have identical b-values of 8, telling you that both equations have identical y-intercepts. So, by definition, x is zero, which means you are left with the b-value of eight, giving you the solution to the system.

Answer:

f(x) = x(x + 2)(x + 9)(x - 8)²

Step-by-step explanation:

Given x = h is a zero of f(x) then (x - h) is a factor

If h has multiplicity 2 then the factor is squared , that is (x - h)²

here the zeros are x = 8 of multiplicity 2 , x = - 2, x = - 9, x = 0

then (x - 8)² , (x - (- 2)) , (x - (- 9)) , x - 0 are the factors, that is

(x - 8)² , (x + 2) , (x + 9) and x

f(x) = x(x + 2)(x + 9)(x - 8)² ← in factored form

Answer: 165 cm^3

Step-by-step explanation:

Formula:

V = (4/3)π r^3

Knowns:

r = 3.4

Work:

- (4/3)π 3.4^3 ≈ 164.64 cm^3

- Now, round .6 to a 1 because it is >4, this turns 164.64 cm^3 into 165 cm^3

Answer:

165 cm^3

Answer:

60

Step-by-step explanation:

All angles in a triangle have to add up to 180

60+ 60 + angle 3=180

120 + angle 3= 180

angle 3 = 60

The resulting equation will be x + y = 4 and 4y =20

GIven the system of equation given as:

x + y = 4

-3x + y = 8

If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:

3x  + 3y = 12

-3x + y = 8

Adding both equation

3y + y = 12 + 8

4y = 20

Hence the resulting equation will be x + y = 4 and 4y =20
