Answer:
add all the numbers and divide then by how many numbers there are in the data.
Step-by-step explanation:
5+7+7+5+1+0+6+8+5+9+8=61
how many numbers are in the data? 11
divide 11 and 61.
61/11=5.54
mean=5.54 (54 repeats. 5.5454545454545 etc.)
Answer:
D, $18,000.00
Step-by-step explanation:
Club A
$3 x is donated where x is the number of donations
Club B
$1.25x is donated where x is the number of donations
The total of donations is 25500.00
Add the donations times the dollar amount for Club A and Club B and you get the total amount donated
$3x +$1.25x = 25500.00
Combine like terms
4.25x = 25500.00
Divide by 4.25 on each side
4.25/4.25x = 25500.00/4.25
x =6000
There were 6000 donations
We want to find Club A donation amount
$3 x is the amount donated
3*6000 = 18000
Answer:
<h2><u>
D. -3</u></h2>
Step-by-step explanation:
The y-intercept of an equation is a point where the graph of the equation intersects the Y-axis. There are several ways to find the y-intercept of an equation, depending on the starting information you have.
<u>How to find the Y-Intercept from the Slope and Point.</u>
Write down the slope and point. The slope or "rise over run" is a single number that tells you how steep the line is. This type of problem also gives you the (x, y) coordinate of one point along the graph. Skip to the other methods below if you don't have both these pieces of information.
- Example 1: A straight line with slope 2 contains the point (-3,4). Find the y-intercept of this line using the steps below.
Answer:
.
Step-by-step explanation:
X=first number
y=second number
x=y+5
3x+2y=30
3(y+5)+2y=30
3y+15+2y=30
5y+15=30
5y=30-15
5y=15
y=3
x=3+5
x=8
