Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
Answer:
0.38
Step-by-step explanation:
45/120 = 0.375 which is equal to about 0.38.
Since you are only looking at the total number of 8th graders, you just look at the amount of 8th graders under the fruit smoothies category as well. That way you are able to find that 45 out of the full 120 8th graders want fruit smoothies.
