Probability is the chance of an event occuring. It is obtained by the formula number of outcomes / total number of possible outcomes.
The probability of a blue jay being the next bird papa sees is given by number of blue jays / total number of birds = 59 / (59 + 68 + 12 + 1) = 59 / 140 = 0.4214
Answer: Option B is correct
The expression to estimate the population of the country in 2005 is given by

Step-by-step explanation:
Since we have given that
In 1985, there was population of 145 millions.
Similarly,
In 1995, there was a population of 190 million .
Use the formula,

where A denotes the initial population and t denotes the number of years.
So, the expression becomes

∵ time period between 1985 to 2005 is 20 years.
So we take t=20 years.
So, the expression to estimate the population of the country in 2005 is given by

Answer:
Its A because it is
Step-by-step explanation:
5 x 0.5 x 3.14 = 7.85
<span>apples = (50+x)(800-10x)
= (40000-500x+800x-10x^2)
= -10x^2 +300x + 40000
Max occurs when x = -b/(2a) = -30/(-2) = 15
= -x^2 + 30x + 4000
Max occurs when x = -b/(2a) = -30/(-2) = 15
