Number of salmon in lake is 360 salmon
<u>Given</u>:
Total number of fish released = 72 salmon
Number of salmon catch with tag = 20%
<u>Find:</u>
Number of salmon in lake
<u>Computation:</u>
Number of salmon in lake = Total number of fish released / Number of salmon catch with tag
Number of salmon in lake = 72 / 20%
Number of salmon in lake = 72 / 0.2
Number of salmon in lake = 360 salmon

I'm assuming you mean students when you write stupids.
Give that x = students, the number of total students is equal to 9 more than 4 times x or:
4x + 9
Set that equal to 101 and solve.
The answer is 23
Answer:
perimeter of the rectangular ground floor
=2(length+width)
length=X+200
width=X
=2(X+200+X)
=4x+400
4x+400 =780
4x =780-400
4x =380
x =95
width=95 feet
length=95+200
=295 feet
Answer:
Step-by-step explanation:
Answer:
The numbers less than 5 are expected to occur 666 times ..
Step-by-step explanation:
First of all, we have to find the probability of rolling a number less than 5 in a single trial
The numbers from 1 to 4 are less than 5 so the probability of rolling a number less than 4 is: 4/6 = 2/3
So,
Expected value = Probability * Number of Trials
= 2/3 * 1000
= 2000/3
= 666 times ..
