Scientific notation is a system for expressing very large or very small numbers in a compact manner. It uses the idea that such numbers can be rewritten as a simple number multiplied by 10 raised to a certain exponent, or power.
First you do 3 to the 2nd power which is 9 then you just add 12+9+50= 71
There is a mandatory fixed rate of $ 35 that Raphael will have to pay once the service call has been made. This fixed rate is the constant.
The per hour rate is $20. Suppose the machine took "x" hours to get fixed. Then the variable part of the repair cost will be
.
Thus, Repair Cost=Fixed Rate Cost+Variable Cost
Or,
where
is the total repair cost. Thus, if Raphael ‘s machine took 2 hour to fix, the repair cost is:
dollars.
Therefore, the last option is the correct option.
The answer would be 114. I did 3 times 38 and thats what i got. I hope it helps:D This is from your friendly Tolkien fan.
Answer:
0.7569, 0.5729,0.4371
Step-by-step explanation:
Given that the books are of only two types either non dash fiction or fiction.
Also probability of selecting a fiction = 0.87 = p
X - no of books fiction selected is binomial with p = 0.87 and n =2
(since each trial is independent of the other and there are only two trials)
a) the probability that both books are fiction=

b) Here n =4 with same p.

c) Prob atleast one is non dash fiction =
This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.
