A bag contains 18 balls. There are 6 red balls, 6 yellow balls, and 6 green balls. A ball is drawn at random and returned. Then another ball is drawn at random. Select ALL statements that are true.
A. The expected probability of drawing a green ball first is the same as the expected probability of drawing a green ball second.
B.There are six possible outcomes.
C.The probability of drawing a red ball first is the same as not drawing a red ball second.
D.The expected probability of drawing a red ball and then a yellow ball is 19.
Answer:
There are 18 balls in the bag:
6 are red
6 are yellow
6 are green.
A ball is drawn at random and then returned.
Then another ball is drawn.
Now, let's analyze each option and let's see if it is true or not.
A) The probability of drawing at random a green ball is equal to the quotient between the number of green balls and the total number of balls.
Then for the first draw, the probability is 6/18
Because the drawn ball is returned, for the second draw we still have 6 green balls and 18 balls in total, then the probability still is 6/18
Statement A is true
B) if we define the notation:
YR
as:
Yellow in the first draw, red in the second draw.
The possible outcomes are:
YR
YG
YY
RR
RG
RY
GR
GG
GY
So we have a total of 9 outcomes, we also can calculate this in the following way:
For the first event (first draw) we have 3 possible outcomes (Y, G, and R)
For the second event (second draw) we have again 3 possible outcomes.
The total number of outcomes is the product between the possible outcomes for each event, this is:
3*3 = 9
Then statement B is false.
C) The probability of drawing a red ball first is:
p = 6/18
The probability of NOT drawing a red ball second, is equal to the probability of drawing a yellow or green ball second (we have 12 balls that are green or yellow, and 18 total balls) then this probability is:
q = 12/18
The probabilities are different, then we can conclude that statement C is false.
fD) The expected probabilty of drawing a red ball and then a yellow ball is the product of the individual probabilities, this is:
prob of drawing a red ball first = 6/18
prob of drawing a yellow ball second = 6/18
Joint probability:
P = (6/18)*(6/18) = (1/3)*(1/3) = 1/9
So statement D is true. (it says 19, i suppose that there is a mistake in this sentence and it actually should say 1/9)

PLEASE HELP! Find the midpoint given (0,11) and (-6,3).
Answer:
(- 3, 7 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (0, 11) and (x₂, y₂ ) = (- 6, 3) , then
midpoint = ( [tex]\frac{0-6}{2}[/tex], [tex]\frac{11+3}{2}[/tex] ) = ( [tex]\frac{-6}{2}[/tex], [tex]\frac{14}{2}[/tex] ) = (- 3, 7 )

A sector of a circle has an arc length of π cm and a central angle of π6 radians. What is the area of the sector?
A. 5π cm²
B. 2π cm²
C. 3π cm²
D. π cm²
Answer:
C
Step-by-step explanation:
The Area of sector is π cm². so option D is correct.
How to find the area of a sector of a circle?The sector of a circle is like a slice of a circular pizza.
[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]
Mathematically π radians = 180 degrees
thus, π /6 radians = 180/6 = 30 degrees
The formula for the length of an arc is;
Ф/360 x 2πr
where Ф, is 30 degrees
And the arc length is pi
so we have
30/360 x 2πr = π
30/360 x 2r = 1
60r = 360
r = 360/60
r = 6 cm
Now the area of a sector is;
Ф/360 x πr^2
30/360 x π36
= π cm^2

I think the bigger number would be 203 but I don't knowwww
Step-by-step explanation:
Let the number of psychology books be 'x'.
and that of sociology books be 'y'.
x + y = 317 (given)
Number of sociology books sold was 89 less than that of psychology books.
y = x - 89
Which means,
x + x - 89 = 317
2x = 317 + 89
2x = 406
x = 406/2 = 203
y = 203 - 89 = 114
Hence, 203 psychology books and 114 sociology books were sold.

The terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.
What is a terminal point?The terminal point of a circle or circular path is the measure of the angle in degrees or radians over the circle, at the endpoint on the coordinate plane.
The equation for the angle is given as,
[tex]\theta=\dfrac{\pi}{4}\rm radians[/tex]
The terminal point and tan 0 has to be found out.As, the value of pi is 180 degrees. Put this value in the above expression as,
[tex]\dfrac{\pi}{4}=\dfrac{180}{4}=45^o[/tex]
Now, as the rotation of it clockwise from the x-axis in quadrant 1to get the degrees of the angle to the terminal point.
Let this is unit circle with radius 1. Therefore, from the unit circle attached below,
[tex]y=\sin(45)\times1=\dfrac{2}{\sqrt{2}}\\x=\cos(45)\times1=\dfrac{2}{\sqrt{2}}[/tex]
[tex]\tan (45)=1[/tex]
Hence, the terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0 is 1.

How much does Henry get? £770 is divided between Mark, Henry & Gavin so that Mark gets twice as much as Henry, and Henry gets three times as much as Gavin. How much does Henry get?
Answer:
henry gets 231
Step-by-step explanation:
my head
Answer:
231
Step-by-step explanation:
Let's consider that Gavin got X pounds.
Then Henry gets 3 times as much as Gavin => 3X
And Mark gets twice as much as Henry => 2 * 3X
Together they get 770, so:
X + 3X + 2*3X = 770
10X = 770 => X = 77
As we mentioned, Henry gets 3X, so
3X = 3 * 77 = 231

The perimeter of the pentagon below is 10.5 units. Four sides of this pentagon have the same length, h, and the other side has a length of 1.7 units, as shown below.
What is the value of h?
A 2.2
B 3.7
C 4.8
D 8.8
Answer:
A 2.2
Step-by-step explanation:
So the perimeter is 10.5 and one side is 1.7 and the others are the same.
The Equation for the perimeter of a pentagon is P = side + side + side + side + side.
Fill it out for the sides.
10.5 = 1.7 + 4h
8.8 = 4h
h = 2.2

Find an equation of the circle that has center (-6, 6) and passes through (3,-4)
Answer:
(x+6)² + (y-6)² = 181
Step-by-step explanation:
equation of the circle in general is (x - a)² + (y - b)² = r²
center is (a, b) in our task a=-6 b=6
so equation of the circle is (x+6)² + (y-6)² = r²
we have point (3,-4) ⇒ x=3 y=-4
put x y in equation of the circle ⇒ (3+6)² + (-4-6)² = r² ⇒r² =181
⇒The equation of a circle is (x+6)² + (y-6)² = 181
Answer:
x²+ y² - 109 = 0
Step-by-step explanation:
The coordinate of centre of circle = (-6 , 6)
Point through which it passes = (3 , -4)
So , Firstly find the distance between the centre and that point that will be equal to the radius . Using Distance Formula we have ,
⇒ D = √ [ ( x - x' )² + ( y + y')² ]
⇒ D = √ [ (3+6)² + (6+4)² ]
⇒ D = √ [ 9² + 10² ]
⇒ D = √ [ 81 + 100 ]
⇒ D = √ 181
⇒ D = 13.45 .
Now substituting the respective values in the general equation of circle .
⇒ ( x - h)² + (y - k)² = r²
Where (h,k) is the centre and r is the radius.⇒ { x - (-6) }² + { y - (6) }² = (13.45)²
⇒ ( x + 6 )² + ( y - 6)² = 13.45²
⇒ x² + 36 + 12x + y² + 36 -12x = 181
⇒ x² + y² + 72 = 181
⇒ x² + y² + 72 - 181 = 0
⇒ x² + y² - 109 = 0
Therefore the equation of the circle is x² + y² - 109 = 0 .select the expression that is equivalent to (x-3)^2
