She made twenty seven over thirty six
Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)
The working equations is

To find

, : (1 - 0.90)/2 = 0.05
To find

, : 1 - 0.05 = 0.95
Degrees of freedom = n-1 = 24 - 1 = 23
This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,
Substitute all values,

Thus the answer is,
Answer:

Step-by-step explanation:
It's given in the question that;
The spinner is divided into 11 equal sections from 0 to 10.
You spin the spinner <u>ONCE!</u><u> </u>
The total number of possibilities is six, and the total number of sample spaces is 11.
So the probability of getting an even number is; 
I hope this helps!
Answer:
Step-by-step explanation:
Cindy is correcy because on "Step 1:" the multiplication was correctly distributed over the subtraction in paranthesis 5(x-2) = 5*x- 5*2 = 5x-10.
Henry was wrrong because he distributed 5 only over x and not over -2 as well 5(x-2) ≠ 5*x-2
The answer is C (-1,-4)
I got the answer by graphing the equation and plotting each the points down to see which one lies on the graph
