Answer:
First option is correct.
Step-by-step explanation:
Let amounts of money James may have after he sees Rita be x.
It is given that either James borrowed $12 from his friend Rita or she borrowed $12 from him.
So meeting Rita second time either he will $12 or he will receive $12.
The amounts of money James may have after second meeting with Rita is:
Case 1: If he pays $12.
.... (1)
Case 1: If he receives $12.
.... (2)
On combining equation (1) and (2), we get
Subtract 42.80 from both sides.
It can be written as
Therefore first option is correct.
101, 102, 100, 100, 110, 109, 109 ,108, 109 average to 105.3
subtracting the mean from each number yields the below-
-4,-3,-5,-5,5,4,4,3,4
Squaring each number gives-
16,9,25,25,16,16,9,16
The average of these numbers is 12.89 to two decimal places, so your variance is 12.89
