Mean is same as average
to find average
add up terms
divided that sum by the number of terms you have
example
mean of x,y,z
x+y+z
3 terms
(x+y+z)/3=mean
so
represent next test score as x
89+94+82+84+98+x
count how many terms ther are (6 terms)
mean is 90
(89+94+82+84+98+x)/6=90
add the like terms
(447+x)/6=90
multiply both sides by 6 to clear fraction
447+x=540
subtract 447 from both sides
x=93
she needs a score of 93 on next test
A point and a line.
<h3>Further explanation
</h3>
Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g.,
.
The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.
Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.
These key terms cannot be mathematically defined using other known words.
- A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
- A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
- A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Let a set of

elements.
We can find

(factorial) of the

element.
However, combination of the element lead to less than

possibilities.
(combining like adding or multiplying)
So the proposition is false.
Answer:
it should be 12/2 or 6 i believe
Step-by-step explanation:
4x4 = 8
8x2 = 16
16-4 = 12
