Step-by-step explanation:
True or False? In reference to different sampling methods, systematic sampling includes the steps: list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected.
Answer:
True
Step-by-step explanation:
In the simple random sampling every individual in the population has an equal chance to be selected in the sample. Systematic sampling is a probability sampling in which selection of elements is made from order frame. These samples are selected based on intervals of the population.
Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6
Answer:
The answer is 2(3)+6
Step-by-step explanation:
The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

identify the sequence 18,13,8,3,-2 PLZ HELPPPPP
The common difference between each term is -5. The nth term of the sequence as follows: aₙ = 18 - 5(n-1)
The given sequence is 18, 13, 8, 3, -2.
To identify the pattern in the sequence, we can observe that each term is decreasing by 5. Starting from 18, we subtract 5 to get the next term, and so on. The common difference between each term is -5.
Using this pattern, we can continue the sequence as follows:
-2 - 5 = -7
-7 - 5 = -12
-12 - 5 = -17
-17 - 5 = -22
The extended sequence would be -2, -7, -12, -17, -22.
In terms of the general formula, we can represent the nth term of the sequence as follows:
aₙ = 18 - 5(n-1)

Alicia bought two slices of pizza and a bottle of juice for $4.95. The juice was $1.65. How much is one slice of pizza?
Subtract the price of the juice from the total then divide the remaining amount by 2:
4.95 - 1.65 = 3.30
3.30 /2 = 1.65 per slice.

A test is worth 50 points. Multiple-choice questions are worth 1 point, and
short-answer questions are worth 3 points. If the test has 20 questions, how
many multiple-choice questions are there?
A. m + s = 50
B. m + 2s = 20
C. m.s= 20
D. m + s = 20
Answer:
d) m + s = 20
m = 5
Step-by-step explanation:
m + 3s = 50
m + s = 20
m + 3(20-m) = 50
m + 60 - 3m = 50
60 - 2m = 50
60 = 50 + 2m
60 - 50 = 2m
10 = 2m
5 = m

What is the slope of a line perpendicular to Line AB given A (6,2) and B (-3,2)
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m of AB using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)
m = [tex]\frac{2-2}{-3-6}[/tex] = [tex]\frac{0}{-9}[/tex] = 0
A line with a slope of zero is a horizontal line, parallel to the x- axis.
Thus a line perpendicular to AB is a vertical line parallel to the y- axis.
The slope of a vertical line is undefined
If 5/x = 15/x+20, what is the value of x/5?
Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
[tex]\frac{5}{x} = \frac{15}{x + 20}[/tex]
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
Since x/5 is the reciprocal of 5/x, we know that we can flip the fraction on the right hand side will be flipped.
Thus, x/5 = (x + 20)/15
Now we cross multiply, 15x = 5(x + 20)
Simplify: 15x = 5x + 100
Subtract 5x from each side: 10x = 100
Divide 10: x = 10
Now plug 10 back into the right hand side: (10 + 20)/15
So, the answer is 2.

A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?
Answer:
142 Grey, 83 white, 76 black
Step-by-step explanation:
If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.
