If I observe a bed of mussels on the coast of California in which five species live where the abundances of each species are 100

babymother [125]

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 $=\frac{Abundance of Selected Species}{Total Abundance}$

Probability (randomly picking the third species) $=\frac{998}{3158}$ = $\frac{499}{1579}$ =0.316

12.89503 rounded to the hundreths is

Mariulka [41]

$\text{The hundredths place is the 2nd place after the decimal}\\\\\text{The number in the hundredths place in this case is 9}\\\\\text{You would round up if the number to the right of it it's 5 or greater}\\\\\text{You would keep it the same if the number to the right of it is 4 or less}\\\\\text{The number to the right of 9 is 5, so round up}\\\\\text{When you round, it would turn into: 12.90, since the 9 turns into a "10",}\\\text{then you carry the one over to the next number}\\\\$

$\boxed{\text{Answer: 12.90}}$

The answer would be 2.4 meters per second. To find this, you would divide the 50 meters by 21 seconds. It equals 2.380952, and rounds to 2.4m/s.

Select the expressions that are equivalent to 8 2/3

user100 [1]

To change a mixed fraction, you'd multiply the number upfront, times the denominator, and then add that product to the numerator
that IS the new numerator, and you keep the denominator
thus $\bf 8\frac{2}{3}\iff \cfrac{8\cdot 3+2}{3}$
