When you are making a graph you would say x verses y.
Answer:
y = -x - 1
Step-by-step explanation:
hello,
this is a line, right?
So the equation should be something like
y = ax+b and we need to find a and b
we can see that the points (-1,0) and (0,-1) are in the line so we can write
0 = a*(-1) + b <=> b - a = 0 <=> a = b
-1 = a*0 + b <=> b = -1
so the equation is
y = -x - 1
hope this helps
Answer:
r=9
Step-by-step explanation:
6 2
---- = ------
r 3
We can use cross products to solve
6 * 3 = 2 * r
18 = 2r
Divide by 2
18/2 = 2r/2
9 = r
I would not consider them to be symmetric. Each section represents 25% of the data and it is obvious from the graphs that the quartiles are not symmetric
Answer: 68
Step-by-step explanation:
As per given , we have
Margin of error : E= 0.10
Critical z-value for 90% confidence interval :
Since , the estimate of true proportion is unknown , then
The formula to find the sample size :-
The required minimum sample size= 68
