Answer:

Randomization can be replaced by accurately matching the sample to the population

You should never replace Randomization, its important. Thats why this is false (I just took this quiz)

Answer:

2nd number line

Step-by-step explanation:

When there is an absolute value inequality of the form  |x+a| ≥ b,

We can say that the solution set (in a number line) would be:

Keeping these points in mind,

|x+3| ≥ 2

we start from x = -3

we go 2 units left and right, so we arrive at x = -5 and x = -1

then we draw arrows to both sides

looking at the choices, we see 2nd answer choices (graph) portrays it correctly.

Answer:

The expression of this sequence is -9n

Step-by-step explanation:

* Lets revise the type of the sequence

- Arithmetic sequence:

- There is a constant difference between each two consecutive

 numbers

* Ex:

# 2  ,  5  ,  8  ,  11  ,  ……………………….

# 5  ,  10  ,  15  ,  20  ,  …………………………

# 12  ,  10  ,  8  ,  6  ,  ……………………………

* General term (nth term) of an Arithmetic Progression:

- U1 = a  ,  U2  = a + d  ,  U3  = a + 2d  ,  U4 = a + 3d  ,  U5 = a + 4d

- Un = a + (n – 1)d, where a is the first term , d is the difference

 between each two consecutive terms

* Now lets look to the problem

- The sequence is : -9 , -18 , -27 , -36

∵ -18 - (-9) = -18 + 9 = -9

∵ -27 - (-18) = -27 + 18 = -9

∵ -36 - (-27) = -36 + 27 = -9

∴ The sequence is arithmetic with common difference -9

∵ a = -9 , d = -9 and n is the position of the term in the sequence

∴ The rule of the sequence is Un = -9 + (n -1)(-9)

* We can simplify it

∴ Un = -9 + n(-9) - (1)(-9) = -9 + (-9n) - (-9) = -9 - 9n + 9 = -9n

* The expression of this sequence is -9n

The expression describing the sequence -9, -18, -27, -36, ... is –n, where n represents the position of the term in the sequence.

The sequence given is -9, -18, -27, -36, ..., and we need to write an expression using n to represent the position of a term in the sequence. This is clearly an arithmetic sequence because each term is obtained by adding a constant value to the previous term. The common difference here is -9 (since -18 - (-9) = -9).

For an arithmetic sequence, the n-th term is given by the formula an = a1 + (n - 1) × d, where a1 is the first term, and d is the common difference. In this case, a1 = -9 and d = -9. Therefore, we can substitute these values into the formula to get:

an = -9 + (n - 1) × (-9)

which simplifies to:

an = -9n

B

Step-by-step explanation:

The area of a parallelogram is base times height.

The height has to be perpendicular to the base, so the base (if you count) is 6 units, and the height is 8 units.

8x6=48 square units

Answer:

vertical translation of - 6

Step-by-step explanation:

given f(x) = 3x + 3

then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift of c units up ↑

• If c < 0 then a shift of c units down

shift from + 3 to - 3 is a vertical shift of 6 units down

Answer:

h=7.5 in

Step-by-step explanation:

see the attached figure with letters to better understand the problem

In the right triangle ABC

sin(CAB)=15/18 ----> opposite side divided by the hypotenuse

In the right triangle CDE

sin(DCE)=h/9 ----> opposite side divided by the hypotenuse

In this problem

∠CAB=∠DCE ------> by corresponding angles

therefore

sin(CAB)=sin(DCE)

15/18=h/9

solve for h

h=15*9/18

h=7.5 in

Answer:

Step-by-step explanation:

7.5 inches is correct

Answer:

3 weeks

Step-by-step explanation:

1 quart = 2 pints

6 quarts = 12 pints,

so 4 pints each week would take 3 weeks (4pints x 3weeks =12pints)

Parallel lines have the same slope so the equation will have the same slope. The y-coordinate is the new y-intercept, so the equation is y = 3x + 8

Hope this helps

Answer:

y = 3x + 5

Step-by-step explanation:

Line y = 3x - 8; slope = 3

Parallel lines, slope is the same so slope of the line that parallel to the line y = 3x - 8 is also 3

Passing thru (1,8)

y - 8 = 3(x - 1)

y - 8 = 3x - 3

y = 3x + 5

Answer:

y = 3x + 5

The y-intercept is the y value when x = 0, or (0 , y)

Based on the graph, your y-intercept is at (0 , 2) or 2

The slope(m) can be found using the slope formula and plugging in 2 points:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

But if you look at the answer choices, if the slope is positive, the line would be going up and to the right

If the slope is negative, the line would be going down and to the right

your answer is A

Answer:

Radius is 13 and Circumferences is 81.64

Step-by-step explanation:

You divide 26 by two to get the radius and multiply 2 time pi times the radius or pi times diameter to get the circumference.

Answer:

radius=13

Circumference=26pi

Area=169pi

Step-by-step explanation:

The radius is half the diameter (SP or PR or PQ). The radius is 13

Area= pi(r)^2

r=radius

r=13

pi(13)^2=169pi

circumference=2pi(r)=(pi)d

r=radius

d=diameter

2(pi)13=26pi

You need to use substitution, to do so, you isolate one of the variables x or y in one equation, and then you substitute that equation into the other.

Since you only need to find x, isolate the y in one of the equations

x - 2y = 4

y = [tex]\frac{x}{2} -2[/tex]

Plug this in and simplify

9x + 2y = 16

9x + 2([tex]\frac{x}{2} -2[/tex]) = 16  Distribute the 2

9x + x - 4 = 16  

10x = 20

x = 2    Your answer is C

Answer:

x=7 units

Step-by-step explanation:

see the attached figure with letters to better understand the problem

we know that

The triangles AMN and APQ are congruent by SAS similarity postulate

The include angle

∠MAN=∠PAQ

Because

Arc MN=Arc PQ

therefore

MN=PQ

substitute the values

38=4x+10

solve for x

4x=38-10

4x=28

x=7 units

x would be 7 units because 4 × 7 = 28 And 28 + 10 = 38

Answer:

Yes, there exists one output for every input

Step-by-step explanation:

* Lets revise how to test the function is one-one function

- Draw a horizontal line (parallel to x-axis) and moved it up and down

- If the horizontal line cut the graph in more than one point, then

 the function is not one-one function

- If the horizontal line cut the graph in only one point, then the

 function is one-one function

- That means one output for every input

* Now lets look to the graph

- If we draw a horizontal line and moved it up and down, the line

 will cut the graph in just one point

- That means every x has different value of y

∴ There is no same y-coordinate for two x-coordinates

* Yes, there exists one output for every input

Step-by-step explanation:

Because our number is odd and the first digit is the same as the last one. Then let call it be aba.

a will contain {1,3,5,7,9} but we have

[tex]2a + b = 5 \\ [/tex]

then

[tex]2a < 5[/tex]

so a will be 1 and b will be 3.

Thus, I am 131.

Answer:

131

Step-by-step explanation:

The sum of 3 digits = 5 with first and last the same and is odd, then

3 digit number is 131

Answer:I would say it's graph 4 if the equation you put is y=5(2)^x

Step-by-step explanation:

If we know that the angle on the left is 80° we know that the angle on the right is also 80°

We can subtract these from 360° and we are left with 200°

Since all four of the remaining angles are congruent we can divide our remaining 200° by 4

When you do that you get 50, meaning each remaining angle is 50°

Making x=50°

Hope this helped!

Answer:

x = 50

Step-by-step explanation:

There are no guarantees that the question can be answered unless the lines meeting at the intersection point are staight lines. You have to assume that to be true.

The angles making up the line starting at the lower right and going up to the upper left are

80 +x + x = 180            80 and one of the two xs are vertically opposite.

80 + 2x = 180               Subtract 80 from both sides.

80-80+2x=180-80        Subtract

2x = 100                        Divide by 2

2x/2 =100/2

x = 50

Answer:

c=20

Step-by-step explanation:

H(c)=6.4+0.6c

6.4 is the constant

when the height of the cups is 18.4 the function is:

18.4=6.4+0.6c

then you subtract 6.4 from both side to get:

18.4 - 6.4=6.4 + 0.6c - 6.4

12=0.6c

c= 12/.6

c=20

Answer:

The number of cups in the stack is 20. I hope this helps!!

Answer:

36 cups

Step-by-step explanation:

every 20 minutes you make 12 cups. 20×3=60, which is 1 hour. You will meed to make 3 pots of coffee that are 12 cups each, 3×12=36

The cups would you serve per hour is 36.

We have given that,

In your job at a restaurant, you made a 12-cup pot of coffee at 7:20 a.m. By 7:40 a.m.

one hour contains a 60 inutes

That is the 1 hour=60 minutes.

Every 20 minutes you make 12 cups.

20×3=60, which is 1 hour.

You will need to make 3 pots of coffee that are 12 cups each

3×12=36

Therefore, the cups would you serve per hour is 36.
