The grizzly bear population in yellowstone national park in 1970 was about 270.Over the next 35 years,it increased by about 115%
yawa3891 [41]

Answer:

581

Step-by-step explanation:

<u>Population of Grizzlys</u>

1970   >>>   270

2005   >>>   115% INCREASE

We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):

115/100 = 1.15

So, that would be now:

1.15 * 270 = 310.5

Increasing, we get:

270 + 310.5 = 580.5

We round to 581

In 2005, the population was about 581

Say that every single class in Full Sails Masters Degree in Game Design has a 5% failure rate
natka813 [3]
The monthly failure rate is q = 5% = 0.05
The monthly pass rate is p = 1 - q = 0.95

We want to determine the probability of 12 passes in 12 consecutive months for a student.
P(12 of 12 successes) = ₁₂C₁₂ p¹² q⁰ = 0.95¹² = 0.5404.

Therefore if we have 100 students, the number that gets through 12  consecutive months is
100*005404 = 54 students.

Answer: 54 students are left after 12 months.
