Answer:
Step-by-step explanation:
Find P(S): P(A) + P(A')= 1
A and A' together comprise the sample space, their probabilities sum 1
(Turn 21.9% into a decimal) P(S)= 0.219
Find P(S'): P(A')= 1-P(A)
The probability of the compliment of A is found by subtracting P(A) from 1.
1 -0.219= 0.781; P(S')= 0.781
Find odds in the favor of events S.
(Round 3 decimal places.)
P(A) / 1- P(A)
.219 /.781= .280
Find odds against event S.
(Round your answer to 2 decimal places)
1- P(A) / P(A)
0.781 / .219= 3.566 ROUNDED 3.57
Using probability concepts, it is found that:
P(S) = 0.219.P(S') = 0.781.The odds in favor of event S are 0.281.The odds against event S are 3.57.21.9% of the organic light-emitting diode (OLED) displays in the world are made by Samsung, hence:
P(S) is the probability of a chip being made by Samsung, hence P(S) = 0.219.P(S') is the probability of a chip not being made by Samsung, hence P(S') = 1 - 0.219 = 0.781.The odds in favor of an event with probability p is given by:
[tex]\frac{p}{1 - p}[/tex]
Hence, the odds in favor of event S are:
[tex]\frac{0.219}{0.781} = 0.28[/tex]
The odds against event S are:
[tex]\frac{0.781}{0.219} = 3.57[/tex]

solving 2 step inequalities give three solutions for each inequality -3(1-z)<9
Answer:
-3, -2 and -1
Step-by-step explanation:
Given the inequality -3(1-z)<9
Expand
-3(1)-3z <9
-3-3z <9
Add 3 to both sides
-3-3z+3<9+3
-3z<12
Divide both sides by -3
-3z/-3 >12/-3
z > -4
The required solutions are values greater than -4 and they are -3, -2 and -1
True or False? A triangle cannot have side that are pararell. Explain your thinking
Answer:
True. It would need two interior angles of 90 degrees to have parallel lines. However the interior angles must add up to 180 in order for it to be a triangle therefore it is true.
Step-by-step explanation:
A triangle cannot have side that are parallel is True.
What is Parallel line?The fundamental characteristics listed below make it simple to recognise parallel lines.
Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.No matter how long you make them, parallel lines will never cross one another.
and, A polygon with three sides and three angles is called a triangle.
So, A triangle does not include any parallel lines because of its shape.
Also, We cannot say a triangle is parallel because a side doesn't have an opposite side.
Hence, A triangle cannot have side that are parallel is True.

M&M plain candies come in various colors. According to the M&M/Mars Department of Consumer Affairs, the distribution of colors for plain M&M candies is as follows.
Color Purple Yellow Red Orange Green Blue Brown
Percentage 17% 18% 17% 7% 6% 10% 25%
Suppose you have a large bag of plain M&M candies and you choose one candy at random.
a. Find P(green candy or blue candy).
b. Are these outcomes mutually exclusive? Why?
Answer:
[tex]P(Green\ candy\ or\ Blue\ candy) = 0.16[/tex]
Yes, they are mutually exclusive
Step-by-step explanation:
Given
Refer to the table in the question
Solving (a): P(green candy or blue candy)
This is calculated as:
[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]
From the question:
[tex]P(Blue) = 10\%[/tex]
[tex]P(Green) = 6\%[/tex]
So:
[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]
[tex]P(Green\ candy\ or\ Blue\ candy) = 6\% + 10\%[/tex]
[tex]P(Green\ candy\ or\ Blue\ candy) = 16\%[/tex]
Convert to decimal
[tex]P(Green\ candy\ or\ Blue\ candy) = 0.16[/tex]
Solving (b): Are they mutually exclusive?
Multiple events A and B are mutually exclusive if;
[tex]P(A\ or\ B) = P(A) + P(B)[/tex]
In (a) above:
[tex]P(Green\ candy\ or\ Blue\ candy) = P(Green) + P(Blue)[/tex]
and this is so every other possible colour of candy
e.g.
[tex]P(Red\ or\ Yellow) = P(Red) + P(Yellow)[/tex]
Hence:
The events are mutually exclusive
what is the unit rate of 56 ounces for every 2 cans

What is Division?
A division is a process of splitting a specific amount into equal parts.
A unit rate means a rate for one of something.
We need to find the unit rate of 56 ounces for every 2 cans
To do this we need to divide Fifty six ounces with two.
56/2
Fifty six divided by two.
We get Twenty eight.

Answer:
250 ft.
Step-by-step explanation:
It seems that you are learning the side-splitter theorem right now. If a line is parallel to one side of the triangle and intersects the other two sides, it divides the side proportionally. From the picture we can tell that the streets are parallel, with a line of intersection. Therefore, we can create the following equation of proportionality:
[tex]\frac{375}{300} = \frac{x}{200}[/tex]
Now that we have this equation, we can use the butterfly method to solve for x. We cross multiply:
[tex]375*200=300x\\[/tex]
Now, all we have to do is isolate the variable to find x:
[tex]75000=300x\\x=250[/tex]
Therefore, the distance of Orange Ave between the 3rd St. and 4th St. is 250 ft.

Find the area of the semicircle. Round your answer to the nearest hundredth.
PLEASEE HELPP
Answer:
Area of semicircle = 226.08 in²
Step-by-step explanation:
Diameter of semicircle = 24 in
We need to find area of semicircle.
The formula used to find area of semicircle is: [tex]Area=\frac{\pi r^2}{2}[/tex]
First we will find radius
We know that: radius = diameter/2 = 24/2 = 12
Now, finding area
[tex]Area=\frac{\pi r^2}{2}\\Area=\frac{3.14\times (12)^2}{2}\\Area=\frac{452.16}{2}\\Area=226.08\:in^2[/tex]
So, Area of semicircle = 226.08 in²
The number of column inches of classified advertisements appearing on Mondays in a certain daily newspaper is normally distributed with population mean of 320 and population standard deviation of 20 inches. For a randomly chosen Monday, what is the probability there will be between 280 and 360 column inches of classified advertisement?
Answer:
The probability there will be between 280 and 360 column inches of classified advertisement
P(280≤X≤360) = P(-2≤Z≤2) = 0.9544
Step-by-step explanation:
Step(i):-
Given that the mean the population = 320
The standard deviation of the Population = 20
Let 'X' be the random variable in a normal distribution
Let 'X' = 280
[tex]Z = \frac{x-mean}{S.D} = \frac{280-320}{20} = -2[/tex]
Let 'X' = 360
[tex]Z = \frac{x-mean}{S.D} = \frac{360-320}{20} = 2[/tex]
Step(iii):-
The probability there will be between 280 and 360 column inches of classified advertisement
P(280≤X≤360) = P(-2≤Z≤2)
= P(z≤2) -P(z≤-2)
= P(z≤2)+P(z≤2)
= 2P(z≤2)
= 2×0.4772 ( from normal table)
= 0.9544

An item that regularly sells for a dollars is on sale for 35% off its regular price. Write an expression that shows the price in dollars after the discount.
Answer:
0.65A = X
Step-by-step explanation:
Given that an item that regularly sells for A dollars is on sale for 35% off its regular price, to write an expression that shows the price in dollars after the discount the following equation must be proposed:
100 - 35 = 65
0.65A = Discount price
Therefore, if the regular price were $ 50, this equation would work as follows:
0.65 x 50 = X
32.5 = X
