Answer:
Mean = 10.181818181818181818181818
Median = 10
Mode = 8
Range = 13 - 8 = 5
Step-by-step explanation:
MEAN 8+8+8+9+9+10+10+12+12+13+13 = 112/11=10.1818 forever.
MEDIAN 8 8 8 9 9 10 10 12 12 13 13
count five in both directions
MODE most numbers in a number scheme
RANGE highest number minus lowest number.
<span>There are several possible events that lead to the eighth mouse tested being the second mouse poisoned. There must be only a single mouse poisoned before the eighth is tested, but this first poisoning could occur with the first, second, third, fourth, fifth, sixth, or seventh mouse. Thus there are seven events that describe the scenario we are concerned with. With each event, we want two particular mice to become diseased (1/6 chance) and the remaining six mice to remain undiseased (5/6 chance). Thus, for each of the seven events, the probability of this event occurring among all events is (1/6)^2(5/6)^6. Since there are seven of these events which are mutually exclusive, we sum the probabilities: our desired probability is 7(1/6)^2(5/6)^6 = (7*5^6)/(6^8).</span>
Answer:
3. x=16
4. x=51
Step-by-step explanation:
3. 3x-8=x+24
2x=32
x=16
4. 2/3(x+27)= 180-(3x-25)
2/3x+18=180-3x+25
11/3x=187
11x=561
x=51
Answer:
300
Step-by-step explanation:
That would be 2.25 / 0.0075
= 300
76.5:100
because if you simplify 100,000 to 100 by diving by 1 k
then you can do the same and divide 76500 by 1k and get 76.5
