Any solution to the graph would need to be inside the blue shaded area.
With the given point (4,-3) 4 would be the X coordinate and -3 is the Y coordinate.
If you put a dot located at (4,-3) it would be in the white area, so it is not a solution.
The answer is No.
Answer:
A. A stratified random sample.
Step-by-step explanation:
Given is -
Archaeologists choose separate samples of plots from floodplain, coast, foothills, and high hills.
We can see that the sample is divided into strata like floodplain, coast, foothills, and high hills, so this is stratified random sample.
Hence, option A is the answer.
i believe the answer would be: 3/100
Answer:
see below
Step-by-step explanation:
h=−4.9t^2 +39.2t
When will if fall back to the ground
When will h=0
0 =−4.9t^2 +39.2t
Factor out a -t
0 = -t (4.9t -39.2)
Using the zero product property
-t =0 4.9t - 39.2 =0
t =0 4.9t = 39.2
t =39.2 /4.9
t =8
It will reach the ground again at 8 seconds
The maximum height is halfway between the zeros
(0+8)/2 = 4
It will reach the max height at 4 seconds, substituting this in to find the max height
h=−4.9 (4)^2 +39.2(4)
h = 78.4 meters
This will only be applicable between t=0 and t=8 seconds
0≤t≤8 seconds
X intercept (6,0)
y intercept (-3,0)
slope is m= 1/2
