Answer:
93
Step-by-step explanation:
The mean of a list of numbers is the sum of the numbers divided by the count of the numbers in the list.
In this case, representing the eighth score with x, the mean is (611+x)/8
Solving for the mean:
88=(611+x)/8
Multiply both sides by 8
8*88=611+x
704=611+x
704-611=x
x=93
Answer:
6 cubic cm
Step-by-step explanation:
A = 6a^2
A = 6(1)^2
A = 6(1)
A = 6
Answer:
---- Set Builder
(50, ∞) ---- Interval Notation
Step-by-step explanation:
Given
x > 50
Required
Write as a
- Set builder
- Interval notation
As Set Builder:
x > 50 means that x is an integer and x is greater than 50.
In set builder notation, integers are represented with z.
So, the above can be represented as:
![\{x\ E\ Z\ |\ x > 50\}](https://tex.z-dn.net/?f=%5C%7Bx%5C%20E%5C%20Z%5C%20%7C%5C%20x%20%3E%2050%5C%7D)
This translates to:
x is a member of the set of integers such that x is greater than 50
As Interval Notation:
In interval notation, we make use of brackets to represent the intervals.
In this case > is represented by (a,b)
Where a and b are the intervals of the notation
Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.
<em>Hence: x > 50 in interval notation is (50, ∞)</em>
Answer:
I am pretty sure one
