Answer:
C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.
Step-by-step explanation:
Given that 20% of the residents in a certain state support an increase in the property tax.
Sample size = 400
We want the sample proportion to be within 0.04 of the true proportion (i.e., between 0.16 and 0.24)
i.e. margin of error <0.04
Std error of sample = 
Critical value = margin of error/ std error = 
We know z value for 95% two tailed roughly equals 2.
Hence 95% confidence is right.
C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.
Answer:
g(x + 7) = 11x + 80
g(x) + g(7) = 11x + 83
Step-by-step explanation:
g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80
g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83
Answer:
yes
Step-by-step explanation:
take for example
in the expression: 3x²+5x+2=0,
the coefficients here are +3 and +5 while +2 is a constant. +3 and +5 are coefficients of the variables x² and x respectively
Answer:
The slope is
. The slope means that the amount of money in the account is decreasing at a rate of $
every week.
Step-by-step explanation:
Given coordinates are
We need to find the slope of the graph, and explain what does slope means for this graph.
The formula for computing slope
is
Where
and
are the point on the line.
Let us plug points
in the equation
Here, the negative sign of slope
represents that the value of the function (budget) is decreasing, with an increase in time (week).
The slope is
. The slope means that the amount of money in the account is decreasing at a rate of $
every week.
