Answer:
f^-1=(-1/4)x+1
Step-by-step explanation:
to solve for the inverse, you can just switch the x and the y:
y=-4x+4
switch:
x=-4y+4
subtract 4 from both sides:
x-4=-4y
divide by -4:
(-1/4)x-(-4/-4)=y
simplify:
(-1/4)x+1=y

Answer:
Based on the result of his test , Thomas should fail to reject null hypothesis at a significance level of 0.01. Thomas sufficient evidence to conclude that the proportion of households without children in the set of all future samples reached by phone is not equal to the proportion of households without children in the population of all households.
Step-by-step explanation:
From the question we see that the p-value is greater than the level of significance (0.01 )so we fail to reject the null hypothesis.
This means that Thomas has sufficient evidence to conclude that the proportion of households without children in the set of all future samples reached by phone is not equal to the proportion of households without children in the population of all households.
