If you graph these points you can easily see that the slope is 1 and the y-intercept is -3. Therefore y=x-3.
The mean is the average, add the numbers together and divide by the quantity of numbers:
10 + 12 + 15 + 12 + 13 + 11 + 10 + 13 = 96
96 / 8 = 12
The mean is 12
The median is the middle value.
Rearrange the numbers from smallest to largest:
10 , 10 , 11 , 12 , 12 , 13 , 13 , 15
There are an even amount of numbers, so find the middle two values, add together and divide by 2:
12 + 12 = 24 /2
Median = 12
I think it’d be 1 1/2 cans because if 4:2 and 4 is yellow, then 4 divided by 2 is 2 cans and then the 3 cans used for blue half that is 1 1/2. Not positive though but this is how I’d do it
The answer would be 15/4
Hope it helps :)
Answer:
"There are a total of 36 coins in the jar" -- third option
Step-by-step explanation:
- The first equation tells us that the <em>"number of quarters is equal tot he sum of number of dimes and nickels"</em>
- The second equation tells us that the <em>" total value of all the coins is $6.05"</em>
- The third equation tells us that the <em>"total number of coins is 36".</em>
First answer choice is wrong (look at meaning of first equation)
Second answer choice is also wrong (look at meaning of second equation)
Third answer choice is correct as it matches the third equation.
Fourth answer choice is wrong since nowhere is says that.
