Answer:
Slope = 
Equation of the line → 
Step-by-step explanation:
Let the equation of diagonal OA is,
y = mx + b
Here, m = Slope of the line OA
b = y-intercept
Slope of a line passing through two points
and
is given by,
m = 
Therefore, slope of the line passing through O(0, 0) and A(3, 4) will be,
m = 
m = 
Since, line OA is passing through the origin, y-intercept will be 0.
Therefore, equation of OA will be,

Answer:
the fourth one
Step-by-step explanation:
F(x) = 3x ; where x is the number of books purchased.
x f(x)
0 0
1 3
2 6
3 9
4 12
5 15
I saw this problem and the instruction was to graph the function and show the domain and range.
The domain is all the x-values while the range is all the y-values.
B is the answer! Enjoy getting it correct!! :)
Answer: 0.0026
Step-by-step explanation:
Given: Mean : 
Standard Deviation : 
Sample size : 
Formula to calculate z-score :-

For X=7.6 hours.


Hence, the probability that their mean rebuild time is less than 7.6 hours = 0.0026
