Answer: 1/50, or 0.02
Step-by-step explanation:
I'm assuming this is 5*10/25/100. if you just follow the equation, you get 50/25/100, which is 2/100, or 1/50.
Answer:
3.16
Step-by-step explanation:
Mean:
(12+14+5+13+11)/5
11
Sum of squares:
12²+14²+5²+13²+11²
655
Variance = 655/5 - 11²
= 10
sd = sqrt(10)

Answer:
y = 1x - 1
Step-by-step explanation:
y = mx + b
m is slope
slope = change in y / change in x = (3 - 2) / (4 - 3) = 1/1 = 1
m = 1 so equation is now y = 1x + b
To find b, substitute any value from the table. Let's use (3,2)
y = 1x + b
2 = 1(3) + b
2 = 3 + b
-1 = b
So equation is y = 1x - 1
I can’t really help you too much with the graphing but what you do with ordered pairs is whatever is the first number (example for point A it’s -2) you go and find it on the horizontal line. Once you find it on the horizontal line you either go up or down the graph by how many units the second number is (4 so you would go up four in the graph) and then you plot the point
