Answer:
29
Step-by-step explanation:
5m-6
5(7)-6=35-6=29
Answer:
–0.5
Step-by-step explanation:
Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.
The odd rolls are 1, 3 and 5. The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.
The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.
The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.
Rolling any even number gives us the same value. The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.
Together we have
1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5
The <u><em>correct answer</em></u> is:
1983 B.C.
Explanation:
To subtract this, we can reverse the order and make the answer negative. The reason for this is that we are taking away more than we have, so we will have a negative answer.
4000-2017 = 1983
In terms of time, though, we don't deal with negatives, we deal with A.D. and B.C. The use of A.D. is for dates after the year 1; B.C. is for anything before this. Since our number is "negative," it will be 1983 B.C.
