A single coin is flipped four times. A) Use an organizational strategy to construct the sample space for this situation. B) How many different outcomes are possible?
Step-by-step explanation:
- A single coin is known to have 2 sides (The head H and the tail T).
The total number of sample space for n number of coins is expressed as 2ⁿ where
n is the total number of coins flipped.
If a single coin is flipped four times, the total outcome will be expressed as;
2⁴ = 16
Hence there are 16 different possible outcomes.
- To construct the sample space (the 16 possible outcomes)
For one flipped coin, the sample space is represented by the set S₁
S₁ = {H, T}
H is Head
T is Tail
For two flipped coin, the sample space is represented by the set S₂
S₂ = S₁×S₁
S₂ = {H, T}×{H,T}
S₂ ={HH, HT, TH, TT}
For three flipped coin, the sample space is represented by the set S₃
S₃ = S₂×S₁
S₃ = {HH, HT, TH, TT}×{H,T}
S₃ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
For four flipped coin, the sample space is represented by the set S₄
S₄ = S₃×S₁
S₄ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}×{H,T}
S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}
Hence the sample space for a single coin flipped 4times is given by the set;
S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT} where;
n(S₄) = 16
Find the value of the missing angle
Answer:
130 degrees.... I am pretty sure
Cus angles of a triangle add to 180 and so the inside angle is 130 and they are vertical angles so they are the same right? right?
Step-by-step explanation:
Answer:
130 degrees
Step-by-step explanation:
I first came up with the equation 30+20+?=180 (I got 180 because every angle in a triangle added up is 180), then added the 30 and 20 to get 50+?=180. I subtracted 50 from both sides and got ?=130. I know that the angle on the inside and the outside are equal because it seems like a reflection, so if the inside angle is 130 the outside angle is 130 degrees too.
Hope this helps you :)

Solve the literal equation
X= (a+b+c)/(ab)
for a.
Answer:
a = (b + c)/(bx - 1)Step-by-step explanation:
Given
x= (a+b+c)/(ab)Solving for a
x = (a + b+ c)/(ab)abx = a + b+ cabx - a = b + ca(bx - 1) = b + ca = (b + c)/(bx - 1)A small company manufactures a certain item and sells it online. The company has a business model where the cost C, in dollars, to make x items is given by the equation
C = 20/3x + 50band the revenue R, in dollars, made by selling x items is given by the equation R = 10x . The break-even point is the point where the cost and revenue equations intersect.
Graph the cost and revenue equations on the xy-coordinate plane provided. Select the "Line" tool. Plot two points, then a line will connect the points.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)
revenue: (0, 0) and (15, 150)

Mr Roman drove from his hometown to another city. He used 12 1/4 gallons of gas for 318 1/2 mile trip. On average, how many miles did Mr. Roman travel per gallon of gas
Answer: 26 miles
Step-by-step explanation:
Gallons of gas used = 12 1/4 = 12.25
Distance of the trip = 318 1/2 = 318.5 miles
The miles that Mr. Roman travel per gallon of gas will be:
= Distance of the trip / Gallons of gas used
= 318.5/12.25
= 26 miles
Mr Roman travelled 26 miles per gallon of gas

the speed of a computer depends on the amount of memory.
Answer:
i believe the answer is...C
Step-by-step explanation:speed(memory) or s(m)
Step-by-step explanation:
Dependent variable states that a variable whose value dependent upon the dependent variable.
For example:
x is the independent variable and f(x) is the dependent variable
Given the statement:
The speed of a computer depends on the amount of memory.
Let m represents the amount of memory and s represents the speed of a computer.
m = Independent variable
s(m) = Dependent variable on m
Then
Answer:speed (memory), or s(m)

Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5

Check the box labeled Show Segment Parallel to BC. Notice that DE intersects two sides of triangle ABC creating a smaller triangle, triangle ADE. How is triangle ADE related triangle ABC to ? How do you know?
Answer: Since corresponding angles of parallel lines cut by a transversal are congruent, ADE = ABC and AED = ACB. So, based on the AA criterion for similarity, ABC ~ ADE.
Step-by-step explanation: Sample answer from Edmentum! Hope It helps :)
The triangle ADE is similar to the triangle ABC.
What is a similar triangle?Similar triangles are triangles whose corresponding lengths are not equal to each other, but their corresponding angles are equal.
The relation between triangle ADE and ABC is shown below:It is given that the line segment DE is parallel to BC.
Since it is parallel to each other, we can say that the angles formed on both the line segments are equal to each other since they are corresponding angles. Angle A is common to both the triangles.
Therefore, we can say that the two triangles are similar because all the angles are the same in each triangle.
Therefore, we have found out that the triangle ADE is similar to the triangle ABC.

Answer:
[tex]\frac{0.5}{4}[/tex]
Step-by-step explanation:
An entire pizza would be represented by the percentage of 100% or the fraction [tex]\frac{100}{100}[/tex]. If we divide this pizza into 4 equal parts that would make one slice a fraction represented as [tex]\frac{25}{100}[/tex] or simplified to [tex]\frac{1}{4}[/tex]. If we now divide this one slice into two equal parts we would divide that fraction by 2 which would give us a new fraction, which would be [tex]\frac{0.5}{4}[/tex]. Represented as a percentage this would mean that this slice is 12.5% of the entire pizza.

Steven is comparing the cost of a fresh lobster dinner at two different restaurants. The first
restaurant charges $51 for the meal, plus $2 per pound for the lobster he picks. At the
second restaurant, Steven would pay $4 per pound for the lobster, in addition to $19 for the
meal. Steven realizes that, in theory, dinner at both restaurants could cost the same amount
if the lobster had a certain weight. How much would Steven pay for his dinner? What is the
weight?
Answer:
Step-by-step explanation:
2x+51=4x+19
32=2x
x=16. The weight is 16 pounds
plug it back in to find the cost
32+51=83. 64+19 = 83. The cost is 83 dollars
