Answer:
Step-by-step explanation:
The given equations are:
(1)
and 
(2)
Now, simply adding equation (1) and equation (2), we get
Now, substituting the value of x=6 in equation (2). we get
Thus, the values of x and y are 6 and 1 respectively.
In order to solve the system of solution, beau can see that in both the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.
Solution:
<u>It should be noted:</u>
<u>Using the formula:</u>
- Slope = Rise/Run
- => Rise = 1; Run = 2
- => Slope = 1/2
Correct option is A.

Answer:
x less than or equal to 86
Step-by-step explanation:
this is because x represents the number of people since the bus cant hold anymore than 86 you can only have 86 or less people on the bus
To answer (a), we will need to find the Z value for 710 hours and 990 hours.
B) 68% of data lies between one standard deviation of the mean.
850 +70 = 920
850 - 70 = 780
