If you're looking for "x"
x/3 = 3
x = 3*3
x= 9
Ok so all you do is add 150+70+15+1000. That equals to $1235
C.62% of the students participated in summer activates.
Answer:
522
Step-by-step explanation:
The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:
(all fish)/(number tagged) = (sample size)/(number in sample tagged)
all fish = (number tagged) · (sample size)/(number in sample tagged)
all fish = 174 · 39/13
all fish = 522
If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
5 - X - X = -1
5 - 2x = -1
-2x = -1 - 5
-2x = -6
X = 3.
