It’s A because yea just it is and grabbed
The answer is A, look at the difference between 0 and 15 (15) and the difference between 5 and 10 (5) then divide them 5/15.
Answer:
<h2>NONE OF THEM</h2>
Step-by-step explanation:
From the graph,
y and x intercepts are 
and approximately 
respectively
for A, C and D : 
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are 
and approximately respectively
for B: 
x and y intercepts are 
and approximately respectively
Therefore x and y intercepts for the lines 
and 
they are not equal to the x and y intercepts of the given graph
I have no clue. im on that same question
Answer:
<u>A. Mean = 402.5</u>
<u>B. Variance = 77,556.25</u>
<u>C. Standard Deviation = 278.49</u>
Step-by-step explanation:
Let's calculate the mean, variance and standard deviation of the set of numbers given:
A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 =<u> 402.5</u>
B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =<u> </u><u>77,556.25</u>
C. Standard Deviation = √Variance = √77,556.25 =<u> 278.49</u>
