Hope this helps, i apologize if i’m incorrect
maybe: Mean
=
2.22
Median =

Mode =
1
and
3

Median: First we put the numbers in order from lowest to highest:
1
,
1
,
1
,
2
,
2
,
3
,
3
,
3
,
4
The median is the number that has the central position.
Median
=
2
Mode: it is the number that appears the most times. In this case, both
1
and
3
appear the same number of times, so they are both modes.
hope this helps!
Answer:
45
Step-by-step explanation:
year 1 : 18 in
every year after that he grows 3 in so 3 in so 3x9=27
then 27+18=45
Basically, this equation is called the "slope intercept form" and to change into into that, you must simplify the equation.
Answer:
$455
Step-by-step explanation:
The computation of the principal is shown below:
As we know that
Amount = Simple interest + Principal
Let us assume the principal be X
So,
Amount = $500
Simple interest = Principal × rate of interest × time period
= X × 5% × 2 years
= X × 0.1
So, the principal is
$500 = X × 0.1 + X
$500 = 1.1 × X
So, the X is $455 i.e principal
