A newspaper editor wants to know whether people who buy the newspaper like the paper’s new format. He prints an alphabetical list of all the employee names and asks every fifth person on the list. Is the sample likely to be biased or unbiased? Explain your answer.

Answer:

4, 2

Step-by-step explanation:

The formulas for 180 clockwise and counterclockwise wise is -x,-y since both of them are negative they would become positive because -x * -x = + same with y.

Answer: (4, 2)

Step-by-step explanation:

If you start by moving it 45 degrees counter clockwise, it will end up as

(4, -2). Then you move it one more time counter clockwise 45 degrees. T would be at (4, 2)

Answer:

-4, -2, 6, 10, 12

Step-by-step explanation:

The function is h(x) = 2x + 4. H(x) is basically just another way of writing "y", so we technically have y = 2x + 4. We can complete the table by substituting the value of x that the table gives us.

The table gives us x = -4 and wants us to find h(x), or y. So, we do y = 2(-4) + 4 and we get y = -4.

The table gives us x = -3 so we do y = 2(-3) + 4 and we get y = -2.

The table gives us x = 1 so we do y = 2(1) + 4 and we get y = 6.

The table gives us x = 3 so we do y = 2(3) + 4 and we get y = 10.

The table gives us x = 4 so we do y = 2(4) + 4 and we get y = 12.

Answer:

D

Step-by-step explanation:

The horizontal cross-sections of the prisms which is at same height as the cone should have same area.

Therefore Option D is the answer.

A cone is a three dimensional figure that has a circular horizontal structure ,  and vertically tapering up till a point.

It is given that

A Pyramid and a cone both have same volume.

Height of cone is same as Height of Pyramid .

Volume of cone = (1/3)πr²h

Volume of a pyramid =  Area of base * h

When both the volume are equated

as height is same

The Area of the base of the cone =  Area of the base of the Pyramid

The horizontal cross-sections of the pyramid which is at same height as the cone should have same area.

Therefore Option D is the answer.

Answer: $11.2

Step-by-step explanation:

Given

Cora bought 90 feet cable for [tex]\$25.20[/tex]

So, the price of a foot is the division of rate and length

[tex]\Rightarrow \text{Price P=}\dfrac{25.20}{90}\\\\\Rightarrow P=\$0.28\ \text{per foot}[/tex]

for additional 40 feet, the cost is

[tex]\Rightarrow 0.28\times 40\\\Rightarrow \$11.2[/tex]

Thus, Cora pays $11.2 for extra 40 feet

Answer:

A.) Y= -4x + 6

Step-by-step explanation:

Given:

Base length of triangle = 40 units

Height of triangle = 9 units

Length of hypotenuse of triangle = 41 units

To find:

Find the value of Tan A

Steps:

Tan of an angle is equal to the opposite length by adjacent length.

So,

Tan A = [tex]\frac{opposite}{adjacent}[/tex]

Tan A = [tex]\frac{9}{40}[/tex]

Tan A = 0.225

Therefore, the exact value of Tan A is 0.225.

Answer:

You can use the time value of money formula.

FV = PV(1 + r)^n

FV = future value

PV = present value

r = interest rate = percentage/100

n = number of compounding periods

FV = 500*(1 + 0.075)^10 = $ 1030.52

Answer:

50

Step-by-step explanation:

Bxh/2

10x10=100

100/2= 50

starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12).

The probability the sum total will be 5 is 4/36.

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".

For the given situation,

The sample space for rolling two 6 sided cube is

s ={

    [tex](1,1), (1,2), (1,3), (1,4), (1,5), (1,6)\\(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)\\(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)\\(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)\\(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)\\(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)[/tex] }

⇒ [tex]n(s)=36[/tex]

The event is getting the probability that the sum total will be 5.

e = { [tex](1,4), (2,3), (3,2), (4,1)[/tex] }

⇒ [tex]n(e)=4[/tex]

Thus the probability that the sum total will be 5 is

[tex]P(e)=\frac{n(e)}{n(s)} \\[/tex]

⇒ [tex]P(e)=\frac{4}{36}[/tex]

Hence we can conclude that the probability the sum total will be 5 is 4/36.

Answer: Infinitely many solutions.

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

Answer:

72 square units

Step-by-step explanation:

you can use the Pythagorean Theorem; because we're dealing with a square then each side can be assigned the same variable, let's use 'a'

a² + a² = 12²

2a² = 144

a² = 72

a = [tex]\sqrt{72}[/tex]

[tex]\sqrt{72}[/tex] can be simplied as [tex]\sqrt{9}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{2}[/tex] which is 3·2·[tex]\sqrt{2}[/tex]

each side has a length of 6[tex]\sqrt{2}[/tex]

A = (6[tex]\sqrt{2}[/tex])² which is 6·6·2 or 72

Answer:

x=6

Step-by-step explanation:

Kindly look at the image provided below.

The image shows the relationship between intersecting secants and their corresponding arcs which is important to understand when looking at problems like these.

The relationship states that an angle formed by two intersecting secants is equal to half the sum of its corresponding arc and its vertical angles corresponding arc.

So ∠FHG = 1/2 ( arc FG + arc EB )

* substitute the given expressions for each angle and arc *

we would then have

15x - 2 = 1/2 ( -2 + 12x + 16x + 10 )

We now solve for x

Step 1 multiply each side by 2

1/2 ( -2 + 12x + 16x + 10 ) *2  = ( the 2 and 1/2 cancels out )  -2 + 12x + 16x + 10

(15x - 2 )2 = 30x - 4

we now have -2 + 12x + 16x + 10 = 30x - 4

step 2 combine like terms

-2 + 10 = 8

12x + 16x = 28x

now we have 30x - 4  = 28x + 8

step 3 add 4 to each side

-4 + 4 cancels out

8 + 4 = 12

Now we have 30x = 28x + 12

step 4 subtract 28x from each side

30x - 28x = 2x

28x - 28x cancels out

now we have 2x = 12

step 5 divide each side by 2

2x / 2 = x

12 / 2 = 6

we're left with x = 6

Answer:

A. 11.25

Step-by-step explanation:

If point C(x, y) divides line segment AB with end points at A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2\\[/tex]) in the ratio on n:m, then the coordinates of point C is:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 \\\\y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given that segment AB is divided by point C in the ratio of 3:1. Given A(3, 12) and B (14, 17). Let coordinate of C be (x, y), hence:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1\\\\x=\frac{3}{3+1}(14-3)+3=\frac{3}{4}(11)+3=11.25 \\\\\\y=\frac{n}{n+m}(y_2-y_1)+y_1\\\\y=\frac{3}{3+1}(17-12)+12=\frac{3}{4}(5)+12=15.75[/tex]

Therefore, the coordinate of point C = (11.25, 15.75)

The x coordinate of point C is 11.25
