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 = 59+68+12+1=140

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 = \frac{\textrm{Number of outcomes of Blue jays}}{\textrm{total number of birds}}= \frac{59}{140} = 0.421

Hence, the probability of a blue jay being the next bird papa sees is 0.421

A circle is centered at H(4, 0) and has a radius of 10. Where does the point L(-2, 8) lie
Anon25 [30]

Answer:

Step-by-step explanation:

HL=√((-2-4)²+(8-0)²)=√(36+64)=√100=10=radius

so L lies on the circumference of circle.

or eq. of circle is (x-4)²+(y-0)²=10²

(x-4)²+y²=100

Put x=-2,y=8

(-2-4)²+8²=100

36+64=100

or 100=100

which is true.

Hence L lies on the circle.

Which function has an inverse that is also a function? {(–1, –2), (0, 4), (1, 3), (5, 14), (7, 4)} {(–1, 2), (0, 4), (1, 5), (5,
Mkey [24]

Answer:

C. {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)}

Step-by-step explanation:

I just did the quiz. Basically all you do is switch the x and y values for each coordinate pair in order to see if it would pass the line test. If it has double X values, it is not a function with an inverse function.
