Answer:
6 is your median and the average is 11.7
Step-by-step explanation:
to find the median, you simply list the numbers in order from greatest to least and determine which is in the middle.
(3, 4, 5, 6, 16, 20, 28 - with 6 there is three numbers on the left and three numbers on the right)
to determine the average, you add all the numbers up and divide by how many numbers you have
3 + 4 + 5 + 6 + 16 + 20 + 28 = 82
82 divided by 7 is 11.71428571 (when simplified its 11.7)
Answer:
4/5
Step-by-step explanation:
1/2=5/10
5/10+3/10=8/10
simplified or 8/10 divided by 2 =4/5 and u cant simplify it anymore
Answer:
The method is to multiply the numbers by there varible
Step-by-step explanation:
Short answer: C
Remark
Since b is all by itself in equation 2, Substitute it into equation 1.
2a + 3b = 5
b = a - 5 Put this result in equation 1. Be sure and use brackets.
2a + 3(a - 5) = 5 Remove the brackets.
2a + 3a - 15 = 5 Notice the -5 inside the brackets becomes - 15
Combine like terms on the left.
5a - 15 = 5 Add 15 to both sides
5a = 5 + 15
5a = 20 Divide by 5
a = 20/5
a = 4
So far, c is the only possible answer.
b = a - 5
b = 4 - 5
b = - 1
