Number patterns can be formed easily when we know the rule. In our case
The rule is n-4 ,
therefore , when n=1 then 1-4 = -3
n=2 then 2-4 = -2
n = 3 then 3-4 = -1
n = 4 then 4-4 = 0
n = 5 then 5-4 = 1
n= 6 then 6-4 = 2
Therefore we get a pattern -3,-2,-1,0,1,2,..............
hence in this case the difference between consecutive pairs is always 1
Her total profit is £35
40x1.50= 60 60-25= 35
Answer:
0.55
Step-by-step explanation:
The right-hand column of the table gives us the probabilities of the probability function. We know from elementary probability theory that the "probability" of any event(s) happening would be from 0 to 1 inclusive.
The total probability of all events would add up to 1. So, we look at the probabilities given for each even, x, and add them:
0.29 + 0.09 + 0.03 + 0.04 = 0.45
All of these probabilities and the probability at x = 2 (the unknown) would add up to 1, so we can say:
0.45 + probability (x = 2) = 1
Probability at x = 2 = 1 - 0.45 = 0.55
Y=4
How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.
