C) 3/5 because they tossed the coin 5 times and out of those 5 times, 3 of them landed with different sides
1. Is correct
2. x^2 - 12
3. 2 / (a-1)
Answer:
B
Step-by-step explanation:
I believe it is B because it is the only one that doesnt have x values that repeat and give different answers.
Ex. For a, the x value in the first and third coords gives both 1 and 3 as answers.
Every x has to have a unique y value, so
(2,10) (3,12) is ok, but (2,10) (2,12) is not.
Sorry if this doesnt make sense haha
Answer:
mean = 12.9
median = 9.5
Step-by-step explanation:
mean = sum of all observations / total no. of observations
= 7+9+10+6+8+12+5+11+48+13 / 10
=129 / 10
= 12.9
median = middlemost no. after arranging in ascending order
= 5,6,7,8,9,10,11,13,48
=9 and 10
=9+10 / 2
= 19 / 2
= 9.5
To solve for this, we need to multiply 55 balloons by 30 days to get the average total, and then the remainder.
(55 x 30) + 245 = 1895 total balloons to begin with.
