y+2=-4(x-1)
Step-by-step explanation:
y-y1=slope(x-x1)
just plug in the numbers you were given and youre good to go
Answer:
0.0893 meters per year
Step-by-step explanation:
- 1/4 is 0.25
- 2 4/5 is 2.8
- divide height by year to get height gain per year
- 0.25/2.8 = 0. 0893 (to 3 SF)
Answer:
Yes, SDS > SDT
Step-by-step explanation:
List S
25, 30, 40, 50, XS
Average list S = 40
So, we could write,
Average list S = 40 = (25 + 30 + 40 + 50 + XS) / 5
Solving for XS
XS = 40 x 5 – 25 – 30 – 40 – 50 = 200 – 145 = 55
SDs = SD (25, 30, 40, 50, 55) = 12.74
List T
30, 40, 45, 50, XT
Average list T = 40
So, we could write,
Average list T = 40 = (30 + 40 + 45 + 50 + XT) / 5
Solving for XT
XT = 40 x 5 – 30 – 40 – 45 – 50 = 200 – 165 = 35
SDT = SD (30, 35, 40, 45, 50) = 7.1
Even at first sight SDS > SDT because 25 is out of the range 30-50, while 45 is within that range.
List S is more spread than list T.
<h3>
Answer: Choice A) 1/3</h3>
================================================
Work Shown:
x = preimage length = 12
y = image length = 4
z = scale factor
z = y/x
z = 4/12
z = (1*4)/(3*4)
z = 1/3
The scale factor is 1/3.
This means the image is 1/3 of the length of the preimage.
