Answer:
Hey!
Your answer is $118.75!
Step-by-step explanation: How did I get this?
<u>STEP 1:</u> So we know that for a ton of rock costs us $47.50...
To get 2 tons all we have to do is to MULTIPLY $47.50 by 2...
<em><u>(47.50 x 2 = 95)</u></em>
<u>STEP 2: </u>So for $95, you will get 2 tons of rock!
Now to get the .5 tons of rock in price form, we have to get the price of the whole 2.5 tons and DIVIDE BY 2
<em><u>(47.50 ÷ 2 = 23.75)</u></em>
<u>STEP 3:</u> So now we have the costs for 2 tons and the price for HALF a ton.
What we do now is easy...we ADD THE VALUES TOGTHER!
<em><u>(95 + 23.75 = $118.75)</u></em>
The result of $118.75 after adding them together is the PRICE OF 2 TONS!
<u>I HOPE THIS HELPED YOU!</u>

Answer:
The population of interest for this student is the students whom are enrolled in statistics classes.
Step-by-step explanation:
Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
The population of interest are all residents of New York State.
A simple random sample of 500 students was selected from all the students enrolled in statistics classes.
This means that the population of interest for this student is the students whom are enrolled in statistics classes.
Answer:
30 - 18 + 24 ÷ 4 = 18
Step-by-step explanation:
The order of operations is
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Use this word PEMDAS to remember the order of operation
Let us solve the problem
30 18 24 4 = 18
∵ 30 - 18 = 12
∵ 24 ÷ 4 = 6
∵ 12 + 6 = 18
That means put (-) between 30 and 18, (÷) between 24 and 4, then put (+) between 18 and 24
∴ 30 - 18 + 24 ÷ 4
- The first operation is the division
∵ 24 ÷ 4 = 6
∴ 30 - 18 + 6
- Start with 30 - 18 because in addition and subtraction we start
with who come first
∵ 30 - 18 = 12
∴ 12 + 6
- Finally add them
∵ 12 + 6 = 18
∴ 30 - 18 + 24 ÷ 4 = 18
