Answer:
For a green and a blue P1 = 8/11 * 3/10 = (80 * 33) / 110^2 = .218
For a blue and a green P2 = 3/11 * 8/10 = (30 * 88) / 110^2 = .218
The probabilities are the same
The probability that Sid takes one counter of each color green and blue from the 11 counters in a bag is 48/121.
What is an additional rule of probability?When two events P(A) and P(B) occurs one time in an event of which occurs two times. Then the probability of occurring exactly one time both events is,
[tex]P=P(A)\times P(B)+P(B)\times P(A)[/tex]
There are 11 counters in a bag. In which,
8 of the counters are green.3 of the counters are blue.Sid takes at random two counters from the bag. Probability that Sid takes green counter is,
[tex]P(A)=\dfrac{8}{11}[/tex]
The probability that Sid takes blue counter is,
[tex]P(A)=\dfrac{3}{11}[/tex]
The probability that Sid takes one counter of each color is,
[tex]P=\dfrac{8}{11}\times\dfrac{3}{11}+\dfrac{3}{11}\times\dfrac{8}{11}\\P=\dfrac{24}{121}+\dfrac{24}{121}\\P=\dfrac{48}{121}[/tex]
Thus, the probability that Sid takes one counter of each color green and blue from the 11 counters in a bag is 48/121.

O 8) Translate the point and give the resulting coordinates.
(-9,6); (5,-2)
Answer:
- 4/7
Step-by-step explanation:
The resulting point is 5 units right and 2 units down, and the resulting coordinates are (- 4, 4).
Used the concept of coordinate that states,
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
The coordinate is (- 9, 6) and (5, - 2).
Now the value of the resulting coordinate is found as,
(- 9 + 5, 6 - 2)
= (- 4, 4)
Therefore, the resulting point is 5 units right and 2 units down, and the resulting coordinates are (- 4, 4).

If (x 2y)dy/dx=2x-y what is the value of.
The second differential of the function is 3/7
Given the differential function [tex](x +2y)=\frac{dy}{dx} (2x-y)[/tex]
Differentiate both sides with respect to x implicitly
[tex](x +2y)=\frac{dy}{dx} (2x-y)[/tex]
[tex]1+2y'=y"(2x-y)+y'(2-y') \\y''=\frac{1+2y'}{(2x-y)+y'(2-y') }[/tex]
Get the first derivative at the point (3, 0)
[tex]y'=\frac{2x-y}{x+2y} \\y'=\frac{2(3)-0}{0+2(3)}\\y'=\frac{6}{6} \\y'=1[/tex]
Substitute into the second derivative to have:

Answer:
x = 6
Step-by-step explanation:
Using the exterior angle theorem
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
79° is an exterior angle of the triangle , then
8x - 13 + 9x - 10 = 79
17x - 23 = 79 ( add 23 to both sides )
17x = 102 ( divide both sides by 17 )

Define suitable populations from which the following samples are selected: (a) Persons in 200 homes in the city of Richmond are called on the phone and asked to name the candidate they favor for election to the school board. (b) A coin is tossed 100 times and 34 tails are recorded. (c) Two hundred pairs of a new type of tennis shoe were tested on the professional tour and, on average, lasted 4 months. (d) On five different occasions it took a lawyer 21, 26, 24, 22, and 21 minutes to drive from her suburban home to her midtown office.
Using sampling concepts, it is found that the suitable populations are:
a) All Richmond residents.
b) Results of all coin tosses.
c) All pairs of the new type of tennis shoe.
d) The average time on all days is takes to drive from her suburban home to her midtown office.
An example of sampling is asking a sample of 500 Buffalo Bills fans if they think their offense should run the ball more.
The population is all Buffalo Bills fans.Hence, following the example, first identifying the sample and then expanding it for the population the items are answered.
Item a:
Sample of 200 Richmond homes, hence, the population is all Richmond residents.
Item b:
Sample from the results of 100 coin tosses, hence the population is the results of all coin tosses.
Item c:
Sample from 200 pairs of the new tennis shoe, hence the population is all the pairs of this new tennis shoe.
Item d:
Sample for the time it took to drive from her suburban home to her midtown office of 5 days, hence, the population is the time for all days.
