Answer:
The Probability of randomly picking the third species=0.316
Step-by-step explanation:
In a bed of mussels on the coast of California in which five species live,
The Abundance of each Species are 100, 500, 998, 12, and 1548
Total Value=100+500+998+12+1548=3158
Abundance of third Species=998
Probability
Probability (randomly picking the third species) 
=
=0.316
Answer:
- 11x
- 40=
- 51x
Step-by-step explanation:
you just add it
$0.30/$1.50= 0.2= 20%
20% of $1.50 = $0.30
Answer:
a]2.3 hrs
b]3.6hrs
Step-by-step explanation:
4hrs = 12 miles
x = 7miles
4 x 7=28/12=2.3
4 x 11=44/12=3.6hrs
Answer:
15
Step-by-step explanation:
The pertinent general formula for this arithmetic progression is
a(n) = a(1) + d(n - 1), where d is the common difference. That difference is d = 4.
Here, a(n) = -5 + 4(n -1)
Therefore, a(6) = -5 + 4(5) = 15
