Answer:
The probability that Tony removes one yellow, one green ,one blue,and then one more blue tennis ball is 0.0039.
Step-by-step explanation:
We are given that a bucket contains five green tennis balls, two yellow tennis balls, six red tennis balls, and eight blue tennis balls.
As we know that, <u>Probability of an event</u> =
Number of green tennis balls = 5
Number of yellow tennis balls = 2
Number of red tennis balls = 6
Number of blue tennis balls = 8
Total number of tennis balls = 5 + 2 + 6 + 8 = 21
{Now it should be notes that Tony removes for tennis balls, without replacement from the bucket means that every time the total number of remaining balls available for selecting will be one less}.
Now, Probability that Tony removes one yellow =
Probability that Tony removes one green =
Probability that Tony removes one blue =
Probability that Tony removes one blue again =
SO, final probability is =
=
= <u>0.0039</u>
Answer:
A,C,D
Step-by-step explanation:
Complete Question:
<em>"Which pairs of points would result in a line with a rate of change of 2:1? select all that apply"</em>
<em>A.(−4,−11) and (−2−7) </em>
<em>B.(5,6) and (−5, 12) </em>
<em>C.(0,−3)and (−4,−11) </em>
<em>D. (0,−3) and (5, 7)</em>
<em />
Rate of change is the slope. 2:1 would mean a slope of simply, 2.
We need to find slope of each of the choices from A - D and see which one has 2. The formula would be:
Where m is the slope and
x_1 is first x point
x_2 is second x point
y_1 is first y point
y_2 is second y point
Let's calculate slope of each of the choices.
A.
THis one is okay.
B.
THis one is not 2:1.
C.
THis one is okay.
D.
This one is okay.
Hence, A, C, and D all have rate of change of 2:1
