we are given with the set of data containing the elements listed above and is asked to find out the standard deviation of the data. SD is used to determine the distance between the points to the best fit line gained from the data. The formula to be followed is the square root of the summation of (x-mean) over n-1. sd is equal to <span>5.13.</span>
Answer:
y = 2x -3
Step-by-step explanation:
y = 2x + b
plug the point in to the formula and solve for b
17 = 2 x 10 + b
b = -3
Use this to write the formula y = mx + b
m is slope
Answer:
8.08 %
Step-by-step explanation:
Let us denote :
score X follows a normal distribution with mean
and standard deviation 
Step 2
The probability that someone scored 21.9 or less is :

Your answer would be 8 Hammond per minute. Hope this helps!
Given :
- 2 - 1/2y = 0
To find :-
Solution :-
<u>The </u><u>gradient</u><u> form</u><u>/</u><u> </u><u>slope</u><u> intercept</u><u> form</u><u> </u>
<u>On </u><u>converting</u><u> </u><u>,</u>
- 2 - 1/2y = 0
- 1/2y = 2
- y = 2*2
- y = 4
- y = 0x + 4
