To find the slope use Y2-Y1/X2-X1.
3-(-5)/1-(-3)
=8/4
=2
the slope of the line is 2.
m=2 plug into y=mx+b
use any set of coordinate points. ill use (1,3)
3=2(1)+b
b=1
SO YES YOU DID IT CORRECTLY!
Answer:
14.54
Step-by-step explanation:
In a <em>weighted average</em> a “weight” is associated to each value.
The weighted mean is computed the following way:
Suppose you want to calculate the weighted mean of the values
a1, a1, …, an
with weights
w1, w2,..., wn
Then
<em>Weighted mean</em> =(w1*a1+w2*a2+... +wn*an)/(w1+w2+...+wn)
In this case we have
a1= 12, w1 = 8
a2 = 13, w2 = 6
a3 = 17, w3 = 12
<u>Weighted mean </u>
(12*8+13*6+17*12)/(8+6+12) = 14.54 rounded to 2 decimal places.
The first thing we need to know is that the Jennifer-Chelsea ratio is as follows:
3: 2
Equivalently:
3/2
To know how much Jennifer invests, we have to:
(3 / (2 + 3)) = x / 125000
Clearing x:
x = 125000 * (3 / (2 + 3)) = 75000
answer
Jennifer invest 75000 $
Answer:
17 packs
Step-by-step explanation:
If each pack of construction paper has 495 pieces
Mrs Perkins would like to get at least 8000 pieces of construction paper
Number of Packs She will need
= Total Pieces Needed/Number of Pieces per pack
=8000/495
=
Now, 16 X 495 =7920 and this is less than the required numbers.
Therefore, She will need at least 17 packs in order to have a minimum of 8000 pieces pf construction paper
