Question is Incomplete, Complete question is given below.
Each morning papa notes the birds feeding on his birdfeeder. so far this month he has seen 59 blue jays, 68 black crows, 12 red robins and 1 cardinal. What is the probability of a blue jay being the next bird papa sees?
Answer:
The probability of a blue jay being the next bird papa sees is 0.421
Step-by-step explanation:
Given:
Number of outcomes of Blue jays = 59
Number of outcomes of Black crows =68
Number of outcomes of red robins = 12
Number of outcomes of cardinal = 1
Total Number of Birds = Number of outcomes of Blue jays + Number of outcomes of Black crows + Number of outcomes of red robins + Number of outcomes of cardinal =
To calculate the probability, it is obtained by the formula number of outcomes / total number of possible outcomes.
Probability of of a blue jay being the next bird papa sees =
Hence, the probability of a blue jay being the next bird papa sees is 0.421
Answer:
90%
Divide 180 by 200, and you get .9. Convert that into. a percentage
Answer:
Step-by-step explanation:
The given equation is
To factor this expression, we can change variables to make easier to see the solution.
and
Applying the change, we have
Now, you can observe that to factor this expression, we just need to find two number which product is 14 and which difference is 5, such numbers are 7 and 2.
However, remember that , so
Applying the zero property, we have
As you can see, the equation has two real solutions and two complex solutions.
Therefore, the right answer is the last choice.
