Given: Different statement
To Determine: Which of the statement would give a valid conclusion
Solution
Please note that the statement must be a true representation of the population
Answer:
C is the correct option
Step-by-step explanation:
To find the probability of P(a or b) we will use the formula:
P(a or b)= P(a)+ P(b) - P(a-b)
Now put the given values in the formula:
P(a or b)= 0.60+0.25-0.15
P(a or b)=0.85 - 0.15
P(a or b)= 0.70
Thus the correct option is C....
First show the statement holds for
. The left hand side is just 8, and the right hand side is
, so it's true.
Assume the statement holds for
, i.e.
and use this to show it holds for
, i.e.
By the assumption above, you have
so the statement is true for all
.
Answer:
a 5/2; b. 2.5; c 0.9; d. 90%
Step-by-step explanation:
first you should try to find the closest multiple of 19 which you should multiply 19 by 5 and get 95. then subtract 97.75-95 which equals 2.75. 2.75 then needs to be divided by the cost per extra minute 0.07 so 2.75 divided by .07 which gets you 39. 39 minutes
