Answer: C
Step-by-step explanation:
A monomial is a expression where in it is x to the power of something, and x cannot be a denominator
It will be b im ask my teacher
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer: Y-intercept is (0,-1/7) and the slope is -3/7
Step-by-step explanation:
State the slope and the y-intercept for the graph of each
equation y= -3/7x–1/7
To find the y-intercept,
you plug in 0 in for x for y= -3/7x–1/7
y=-3/7(0)-1/7
y=0-1/7
y=-1/7
The y-intercept is (0,-1/7)
To find the slope, you first check that the equation is in the form of y=mx+b
y= -3/7x–1/7 is in the from of y=mx +b.
The m is the slope
hence, in y= -3/7x–1/7 the slope is -3/7
