Answer:
The margin of error is multiplied by 
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic of the given confidence level
- s is the standard deviation of the sample (or of the population if it is known)
Since margin of error is proportional with inverse of 
,
if we cut the sample size in half, the margin of error is multiplied by .
Find slope
slope for points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-4,3), (4,5)
(5-3)/(4-(-4))=2/(4+4)=2/8=1/4
slope=1/4
y=mx+b
m=slope
b=yint
solve for yint
input a point
(4,5)
x=4
y=5
5=(1/4)4+b
5=1+b
minus 1
4=b
y=1/4x+4
Answer:
a force of 1250lb is exerted
Step-by-step explanation:
since the force of the wind varies jointly as the area of the surface and the square of the velocity,
let f = force
a = area
velocity =v
from the above statement, we find out that
----1
that is 
-----2
where k is a coefficent of proportionality
since velocity of wind in mph,v =50
and force in lb = 20
and surface area =
from eqn 2
we have that
making k subject of the formula
we have that
that means that 
---3
however, when velocity = 125mph
surface area =
putting values in eqn 3 we have
hence a force of 1250lb is exerted
