There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in an apartment.
How many people from the entire population would you expect to live in an apartment?
Answers
Answer:
16,000 people
Step-by-step explanation:
Let's write a ratio
8,000:20,000
Let's write another ratio
x:40,000
We can write a percent proportion.
[tex]\frac{8,000}{20,000} =\frac{x}{40,000}[/tex]
We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000

A. T> 600
B. T<600
Answers
Answer:
A
Step-by-step explanation:
Answer: B. T<600
Step-by-step explanation:
if the monthly plan is $30, we subtract that from $60 to get that she has $30 left. Then divide 30 by 0.05 to get exactly 600. but, you can’t forget that other $0.05 per month so it would have to be less than 600 texts

Find the mean deviation for this data.
Select one:
1.91
2.21
1.67
4.98
Answers
Answer: The answer is 1.67
Step-by-step explanation:
First, find the mean by adding all of the numbers and divide them by how many numbers there are, so 17+15+16+20+15+19=102 Then 102/6= 17. Then take the mean and subtract it by every number, and make sure it is the number’s absolute value.
17-17=0, 15-17=2, 16-17=1, 20-17=3, 15-17=2, 19-17=2. Then add all of those numbers and divide them by how many numbers there are. 0+2+1+3+2+2=10. 10/6=1.67
Answer:
1.67
Step-by-step explanation:
[tex]\frac{17 + 15 + 16 + 20 + 15 + 19}{6} = \frac{102}{6} = 17[/tex]

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2
Answers
Step-by-step explanation:
We have to simplify the given expression:
1. 3x+2y-2x+23x+2y−2x+2
Combining the like terms,we get the second step as
2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)
Now, taking 'x' common from the first two terms, we get third step as:
3. (3-2)x+2y+2(3−2)x+2y+2
Now, simplifying the expressions among the like terms, we get fourth step as:

We can identify which case it is by looking at our results. If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.Step-by-step explanation:

A wooden bench was originally priced at $50 but went on sale for 20% off. If Presley bought the wooden bench and paid a 5% sales tax, how much did he pay in total?
Answers
Answer:
$42.00
Step-by-step explanation:
20% OF 50 = 40
Before Tax Price: $40.00
Sale Tax: 5.00% or $2.00
After Tax Price: $42.00
Answer:
$42
Step-by-step explanation:
To get the new bench price, you multiply 50 × 0.2, which gets you 10, then you subtract 50-10, which is 40, and $40 is the price of the bench on sale. (You could also do 50 × 0.8 to avoid a step and still get the same answer).
You then take 40 and multiply is by 0.05 to get the tax, which would be $2. From here, you add 40+2 to get $42, the amount of money Presley paid for the bench.

[tex]\huge\boxed{\text{A) -3}}[/tex]
Step-by-step explanation:
To find the value of this equation when [tex]x=-2[/tex], we can substitute this value inside the equation and use PEMDAS to successfully find the value.
With the expression of [tex]2x^2+4x-3[/tex], let's substitute -2 in as x.
[tex]2(-2)^2 + 4(-2) - 3[/tex]Now let's follow PEMDAS to solve this equation.
PEMDAS states that when solving an expression/equation, the order we must follow is
ParenthesesExponentsMultiplication/DivisionAddition/SubtractionWe can now solve for this.
We see that exponents come before multiply and dividing. Therefore:
[tex]2(-2)^2 = 2 \cdot (-2)^2 = 2 \cdot 4 = 8[/tex]So the value of our first term is 8.
Our second term will be [tex]4 \cdot -2 = -8[/tex], and our last term will remain -3.
Adding these values together:
[tex]8 - 8 - 3 = -3[/tex]
Therefore, the value of this expression when x = -2 is -3.
