Answer:
Probably y=2x+60
Step-by-step explanation:
It seemed to fit best, dont count on my answer tho, not 100% sure :(
When I put the line through the points, the y intercept was around 50/60 and the slope is positive so it eliminated a few answers. then I chose y=2x+60 since that slope seemed more correct than a slop of 8.
Answer:
Yes, because it is a ratio, it is a proportional relationship.
If you are required to find A, then A=sin inverse(4/5)
Clearly, we can see that x+2 is a factor of the given polynomial.
Answer:
0.0735,0.0179,0.7026
Step-by-step explanation:
Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.
Sample size = 49
Population mean = 78
Population std deviation = 28
Std error of sample mean = 
a)
: N(78, 4)
b) 
(by converting to Z and finding value from Z table)
c) P (x overbar less than or equals 69.6 )
=
d) P (75.8 less than x overbar less than 88 )
=
