Consider a different experiment: EXPERIMENT: A bag contains 3 red balls, 4 blue balls, 4 green balls and 3 yellow balls. One ball is drawn at random and then returned to the bag. Then a ball is drawn again, possibly the same one or a different one.
(a) Specify the sample space (set of outcomes) and probability distribution of the outcomes.
(b) What is the probability that both balls drawn were red balls?
(c) Starting over with all 14 balls back in the bag, what is the probability that both draws were balls of different colors?
Answer:
a) Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) 0.0459
c) ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )
Step-by-step explanation:
Total number of balls = 3 + 4 + 4 + 3 = 14 balls
3 Red balls = 3/14
4 blue balls = 4/14
4 green balls = 4/14
3 yellow balls = 3/14
a) Determine the sample space and probability distribution of outcomes
since ball is drawn with replacement
Sample space = RR, RB, RG, RY, BB, BR, BG, BY, GG, GR, GB, GY, YY, YR, YB, YG .
i.e. The sample space has 16 possible combination
probability distribution of outcomes
= (3/14*3/14), (3/14*4/14), (3/14*4/14), (3/14*3/14), (4/14 *4/14 ), (4/14*3/14), (4/14 * 4/14), (4/14 * 3/14 ), ( 4/14 *4/14 ), (4/14*3/14), ( 4/14 *4/14 ),
(4/14*3/14), (3/14 *3/14 ), (3/14*3/14), (3/14 *4/14 ), ( 3/14 * 4/14 )
b) Determine P( R and R )
P ( R and R ) = 3/14 * 3/14
= 9/196 = 0.0459
C) Determine probability of drawing two different balls
P( R and B ) + P ( R and G ) + P ( R and Y ) + ------ P ( Y and G )
= ( 3/14 * 4/14 ) + ( 3/14 * 4/14 ) + ( 3/14 * 3/14 ) + ------ ( 3/14 * 4/14 )
Determine the location and absolute maximum and absolute minimum for the given function f(x)=(_x+2)^4 where 0
Answer:
the minimum is 0 and the maximum is 16.
Step-by-step explanation:
For a function f(x), the maximum is defined as:
f(xₐ)
such that:
f(xₐ) ≥ f(x) for every value of x in the domain.
And the minimum is:
f(xₙ)
Such that:
f(xₙ) ≤ f(x)
for every value of x.
Now, in this case we have the function:
f(x) = (-x + 2)^4 in the range 0 < x < 3
First, let's analyze our function.
We can see that the exponent is even, then:
f(x) = (-x + 2)^4
Can be equal to zero or larger than zero.
Then the minimum will be f(x) = 0
To find this, we need to find the value of x such that:
-x +2 = 0
2 = x
Then the minimum is:
f(2) = (-2 + 2)^4 = 0
For the maximum, we can just play with the other values in the range and see which one gives the larger value of f(x).
Again, because f(x) = (-x + 2)^4 , the maximum will be at the value of x such that:
|-x + 2| is maximized.
As we have a negative sign multiplying x, the smaller value in the range:
x = 0
is the one that maximizes that:
|-0 + 2| = |2| = 2
Evaluating f(x) in x = 0 we get:
f(0) = (0 + 2)^4 = 16
Then the minimum is 0 and the maximum is 16.

Answer:
option C
Step-by-step explanation:
Since three sides of the triangle are same , the triangle is equilateral.
Again every equilateral triangle is also an isosceles triangle.
The angles of an equilateral triangle are the same and is 60°. Therefore it is acute ( < 90°)

What is the probability that a standard number cube will show a two, five, or six when it is rolled?
Answer:
[tex]p=0.5[/tex]
Step-by-step explanation:
A standard die has six numbers (1 through 6). That means there is a 1/6 probability of rolling any one number. There is a 3/6 probability of rolling one of the selected numbers which simplifies to 1/2 or 0.50

What is the value of log27 165
The solution of the logarithmic function log₂₇165 found using logarithmic properties is :
(1 + log ₃55)/3.
What is a logarithmic function?
The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. The usage of logarithmic functions makes it simple to determine some of the non-integral exponent values. The common logarithmic function, which has a base of 10, is identified by the symbols log₁₀ or log.
We are asked to solve the following logarithmic function.
log₂₇165
Here the base of the log is 27.
According to logarithmic properties, we can write the above functions as:
log₂₇165 = log 165 / log 27
If we are dividing the numerator and denominator by log 3, then the new base will become 3.
(log 165 / log 3) / (log 27/log3) = log ₃165 / log₃ 27
Now we can solve as follows,
log ₃165 / log₃ 27 = log ₃(3*55) / log₃ (3³) = [log ₃(3)+log ₃(55)] / 3log₃3
= (1 + log ₃55)/3
Therefore the solution of the logarithmic function log₂₇165 is
(1 + log ₃55)/3.

Which graph matches the equation y+3=2(x+3)?
A (0,3) (-3,-3)
B (0,6) (-3,0)
C (0,-3) (-3,-9)
D (3,3) (0,-3)
Answer:
A (0,3) (-3,-3)
Step-by-step explanation:
A graph will match the equation if both the coordinates points replaced in the equation generate a identity.
When x = -3
[tex]y + 3 = 2(x + 3)[/tex]
[tex]y + 3 = 2(-3 + 3)[/tex]
[tex]y + 3 = 0[/tex]
[tex]y = -3[/tex]
So (-3,-3) is part of the graph.
When x = 0
[tex]y + 3 = 2(x + 3)[/tex]
[tex]y + 3 = 2(0 + 3)[/tex]
[tex]y + 3 = 6[/tex]
[tex]y = 3[/tex]
So (0,3) is part of the solution.
(-3,-3) and (0,3), so option A.

*SEE PICTURES FOR ACTUAL MEASURES*
The actual MetroPass is 2.1 inches wide and 3.4 inches long. Moniques group wants the MetroPass float to be 74.8 ft long. Her group needs to find the width of the MetroPass float.
How wide, in feet, will the MetroPass float be? Round you answer to the nearest tenth. Show your work.
*WILL BE MARKED BRAINLIEST*
Answer:
Width = 64.4 feet
Step-by-step explanation:
A scale is a representative faction that can be used to either increase or decrease the dimension of a given object.
scale = [tex]\frac{nem length}{actual length}[/tex]
But,
1 feet = 12 inches
For the actual MetroPass;
length = 3.4 inches = 0.2033 feet
width = 2.1 inches = 0.175 feet
The MetroPass float has a length of 74.8 feet.
scale = [tex]\frac{74.8}{0.2033}[/tex]
= 367.93
So that;
the width of the MetroPass float = 0.175 x 367.93
= 64.388
Therefore, the width of the MetroPass float is 64.4 feet.

Step-by-step explanation:
7 + 2x + 3 = x + 10
2x - x = 10 - 7 - 3
x = 0
What?
I don't think this helps...
Answer:
x = 0.
Step-by-step explanation:
The distance between the point U and W are x + 10 and 2x + 3 + 7 so we can make the following equation:
x + 10 = 2x + 3 + 7
x + 10 = 2x + 10
Subtract 10 from both sides:
x = 2x
Subtract x from both sides:
0 = x
x = 0

(x, y) = (-7, 5)
Step-by-step explanation:
I find a graphing calculator to be useful for solving equations by graphing. The graph shows the solution to be ...
(x, y) = (-7, 5)
__
In these equations, the y-coefficients are the same, so we can eliminate y by subtracting the first equation from the second.
(4x -6y) -(-2x -6y) = (-58) -(-16)
6x = -42 . . . . . . . . . simplify
x = -7 . . . . . . . . divide by 6
Substituting into the first equation gives ...
-2(-7) -6y = -16
6y = 30 . . . . . . . . . . add 16+6y to both sides
y = 5 . . . . . . . . .divide by 6
The solution is (x, y) = (-7, 5).

which expression could be used to determine the product of -4 and 3 1/4
Answer:
B (-4)(3) + (-4)(1/4)
Step-by-step explanation:
We must find the product of -4 and 3 1/4, which is (-4)(3 1/4). We know that 3 1/4 = 3 + 1/4, so we substitute that to the expression we want.
(-4)(3 1/4) = (-4)(3 + 1/4)
Using the distributive property, we distribute the -4 to the 3 and the 1/4 and the expression becomes
(-4)(3 + 1/4) = (-4)(3) + (-4)(1/4)
I hope this helps! :)
