Answer:
1.) It is biased
2.) No
3.) Yes
4.) No
Step-by-step explanation:
1.) It is biased as it is predisposition to one particular outcome over another.
2.) No, because biased in research leads to unrepresentative outcomes as the estimates is predisposed to the left or to the right of the true values.
3.) Yes. Since the selection of shift has an equal probability of being chosen.
4.) No. The probability that the sample accurately reflects the efficiency of the workers, the standard should be 95%.
Answer:
67.15
Step-by-step explanation:
Answer:
x = y^2 – 7
Step-by-step explanation:
The first step in finding the inverse of y = f(x) can be to write the equation x = f(y). The equation shown above is such an equation.
Time taken for the amount deposited to grow to $5000 will be found as follows:
A=P(1+r/100*n)^nt
where:
A=amount
P=principle
r=rate
n=number of terms
t=time
thus plugging in our values we have:
5000=3587.39=(1+4.2/200)^2t
solving for t we have:
1.393771=1.021^2t
2t=ln1.393771/ln1.021
2t=16.111
t=8.055685 years~8 years
120 is good engough if you dont kn o
