Answer:
Step-by-step explanation:
die rolled and coin flipped
Jacob wins if tail and even number
Amanda wins if head
Outcomes,
1H 2H 3H 4H 5H 6H
1T 2T 3T 4T 5T 6T
12 outcomes.
b) Prob of Jacob winning (tail and even number)
2T 4T 6T
3/12 total outcomes
1/4 probability
c) prob of Amanda winning (head)
6/12
1/2
d) the game is not far because both people do not have equal chances of winning
e) Yes, Tail and odd is where the outcome is not decided.
There are 12 different outcomes. The probability that Jacob wins is 1/4, and the probability that Amanda wins is 1/2. The game is not fair. There are no outcomes where the game is not decided.
Explanation:To find the number of different outcomes, we need to multiply the number of outcomes for flipping the coin and rolling the die. For flipping a coin, there are 2 possible outcomes (H or T), and for rolling a 6-sided die, there are 6 possible outcomes (1, 2, 3, 4, 5, or 6). Therefore, the total number of different outcomes is 2 * 6 = 12.
To find the probability that Jacob wins, we need to find the number of favorable outcomes for Jacob (tail and even number) divided by the total number of outcomes. There are 3 favorable outcomes (T2, T4, T6) out of 12 total outcomes, so the probability is 3/12 = 1/4.
To find the probability that Amanda wins, we need to find the number of favorable outcomes for Amanda (head) divided by the total number of outcomes. There are 6 favorable outcomes (H1, H2, H3, H4, H5, H6) out of 12 total outcomes, so the probability is 6/12 = 1/2.
The game is fair if the probabilities of winning for Jacob and Amanda are equal. Since the probabilities are different (1/4 for Jacob and 1/2 for Amanda), the game is not fair.
There are no outcomes where the game is not decided since there is always a tail or a head flipped and a number rolled on the die, resulting in a win for one of the players.

Spencer puts an $1880 item on layaway by making 20% down payment and agreeing to pay $170 a month. How many months sooner would he pay off the item if he increased his monthly payment to $260?
Answer:
Spencer will pay off the item 3 months sooner if he pay $260 instead of $170 a month
Step-by-step explanation:
Total Amount = $1880
Down Payment = 20%
Monthly payment = $170
if Monthly payment increased from $170 to $260, How many months sonner Spencer will pay off?
So, First calculate the down payment
Down payment = 20% of 1880
= (20/100) * 1880
= 376
Amount left to be paid = 1880 - 376
= 1504
Total months to pay off for Spencer if he pay's $170 a month:
1504/170 = 8.8 ≈ 9 months
Total months to pay off for Spencer if he pay's $260 a month:
1504/260 = 5.7 ≈ 6 months
So, 9 -6 = 3 months
So, Spencer will pay off the item 3 months sooner if he pay $260 instead of $170 a month

Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they weighed 3.8 pounds, and cost $5.84.
How many pounds of apples and how many pounds of bananas did Troy buy?
2.6 pounds of apples; 1.2 pounds of bananas
1.9 pounds of apples; 1.9 pounds of bananas
1.5 pounds of apples; 2.3 pounds of bananas
1.2 pounds of apples; 2.6 pounds of bananas
Answer:
2.6 pounds of apples; 1.2 pounds of bananas
Step-by-step explanation:
A = pounds of apples and B = pounds of bananas
The total weight is 3.8 pounds, so:
A + B = 3.8
Apples are $1.90 per pound and bananas are $0.75 per pound, and the total cost is $5.84, so:
1.90A + 0.75B = 5.84
We can solve the system of equations using either elimination or substitution.
Using substitution:
1.90A + 0.75(3.8 - A) = 5.84
1.90A + 2.85 - 0.75A = 5.84
1.15A = 2.99
A = 2.6
B = 3.8 - A
B = 1.2

a circle has a radius of 2 cm. find the length s of the arc intercepted by a central angle of 1.9 radians.
Answer:
3.8 cm
Step-by-step explanation:
The arc length formula is s = r·Ф, where Ф is the central angle in radians.
Here, s = (2 cm)(1.9 rad) = 3.8 cm
The length of the arc intercepted by a central angle of 1.9 radians in a circle with a radius of 2 cm is 3.8 cm, calculated by multiplying the radius (2 cm) by the angle in radians (1.9).
Explanation:A circle has a radius of 2 cm and we need to find the length (s) of the arc intercepted by a central angle of 1.9 radians. The formula to find the arc length 's' for a circle is s = r * Θ, where 'r' is the radius and 'Θ' is the central angle in radians. We have 'r' = 2 cm and 'Θ' = 1.9 radians.
To find the arc length 's', we simply multiply the radius by the angle:
s = 2 cm * 1.9 radians = 3.8 cm.
Therefore, the length of the arc intercepted by a central angle of 1.9 radians in a circle with a radius of 2 cm is 3.8 cm.

A.Mid- term exams
B.Final exams
C.They have the same IQR
D.There is not enough information
Answer:
B. Final Exams.
Step-by-step explanation:
The IQR is the difference between the lower and upper quartiles of the data and is a measure of the spread of the data.
Mid Term Exam:
First find the Median
This is (95+92)/2 = 93.5.
The Lower quartile is the median of the bottom 5 values = 88.
The upper quartile is the median of the top 5 values = 100
So the IQR = 100 - 88 = 12.
Final Exam.
We find the IQR of the Final exam data in a similar way:
It comes to 93 - 78 = 15.

The surface area-to-volume ratio is used in Biology to predict cell efficiency in eliminating wastes or procuring nutrients by diffusion.
Explanation:In Biology, the surface area-to-volume ratio is used to predict which cells might eliminate waste or procure nutrients faster by diffusion. This ratio is calculated by dividing the surface area of a cell by its volume. Cells with a larger surface area-to-volume ratio are more efficient at exchanging materials with their surroundings.
For example, consider a small cell with a high surface area-to-volume ratio. This cell has a relatively larger surface area compared to its volume, which allows for faster diffusion of nutrients into the cell and waste products out of the cell. In contrast, a larger cell with a lower surface area-to-volume ratio has a relatively smaller surface area compared to its volume, resulting in slower diffusion.
By analyzing the surface area-to-volume ratio, we can predict which cells have a greater capacity for diffusion and therefore can eliminate wastes or procure nutrients at a faster rate.

Use the functions a(x) = 3x + 10 and b(x) = 5x − 6 to complete the function operations listed below.
Part A: Find (a + b). Show your work.
Part B: Find (a - b). Show your work.
Part C: Find (a * b). Show your work.
Answer:
(a + b) = 8x +4
(a - b) = -2x +16
(a * b) = [tex]15x^{2}+32x-60[/tex]
Step-by-step explanation:
We have been given the functions;
a(x) = 3x + 10 and b(x) = 5x − 6
Part A:
(a + b) = a(x) + b(x) # we simply add the two given functions
(a + b) = 3x + 10 + 5x − 6
(a + b) = 8x + 4
Part B:
(a - b) = a(x) - b(x) # we simply subtract the two given functions
(a - b) = (3x + 10 ) - (5x − 6)
(a - b) = 3x + 10 -5x +6
(a - b) = -2x + 16
Part C:
(a * b) = a(x)*b(x)
# we simply find the product of the two given functions
(a * b) = (3x + 10)*(5x − 6)
(a * b) = [tex]15x^{2}-18x+50x-60=15x^{2}+32x-60[/tex]
Part A
The functions a(x) = 3x + 10 and b(x) = 5x − 6 to complete the function operations listed below.
(a+b)(x)=a(x)+b(x)
(a+b)(x)=(3x+10)+(5x-6)
(a+b)(x)=3x+5x+10-6
(a+b)(x)=8x+4
Part B.
(a-b)(x)=a(x)-b(x)
(a-b)(x)=(3x+10)-(5x-6)
Expand the parenthesis to get:
(a-b)(x)=3x+10-5x+6
(a-b)(x)=3x-5x+10+6
(a-b)(x)=-2x+16
Part C
(a*b)(x)=a(x)*b(x)
(a*b)(x)=(3x+10)*(5x-6)
We expand to get:
[tex]a \times b = 15 {x}^{2} - 18x + 50x - 60[/tex]
[tex]a \times b = 15 {x}^{2} + 32x - 60[/tex]

the angle of elevation from a point 25 feet from the base of a tree on level ground to the top of the tree is 30 degrees. which equation can be used to find the height of the tree
Answer:
the equation to find the height is: x = 25 * tan(30°) and the height is x = 14.43 feet
Step-by-step explanation:
Length of tree = 25 feet
Angle of elevation = 30 degrees
Equation for the height of tree=?
Let x represent the height.
We know that tan Ф = Perpendicular/Base
tan Ф = height of tree/ length of base
tan Ф = x/l
=> x = l*(tanФ)
x = 25 * tan(30°)
Now, putting values:
x= 25 * tan(30°)
x = 25 * 0.577
x = 14.43 feet
So, the equation to find the height is: x = 25 * tan(30°) and the height is x = 14.43 feet

what is b in 12-b=12.5
Answer:
b=-.5
Step-by-step explanation:
The value of b in the equation 12 - b = 12.5 is determined by subtracting 12 from both sides and then multiplying by -1, resulting in b = -0.5.
Explanation:The student is asking to solve for b in the equation 12 - b = 12.5. To find the value of b, you need to isolate the variable on one side of the equation. This is done by subtracting 12 from both sides, resulting in -b = 12.5 - 12, which simplifies to -b = 0.5. To get b by itself and not -b, you multiply both sides of the equation by -1, giving b = -0.5.

Step-by-step explanation:
In corresponding angles formed by parallel lines intersected by a transversal line, the angles are equal. So, if the measure of angle 6 is 21°, the measure of corresponding angle 4 will also be 21°.
Explanation:The subject of this question is geometry, specifically dealing with parallel lines and the angles formed when a line intersects them. In the given diagram, we are told that lines a and b are parallel (represented as a || b). Therefore, we can use the properties of parallel lines to find the measure of angle 4. When a line intersects two parallel lines, it forms corresponding angles which are equal. Since we know the measure of angle 6, which is 21°, and angle 4 and 6 are corresponding angles, therefore the measure of angle 4 is also 21°. So, the answer is A) 21°.

At a college production of A Streetcar Named Desire, 400 tickets were sold. The ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700. How many tickets of each type were sold if the combined number of $8 and $10 tickets sold was 7 times the number of $12 tickets sold?
Answer:
There are 200 $8 tickets
There are 150 $10 tickets
There are 50 $12 tickets
Step-by-step explanation:
Let a = number of $8 tickets
Let b = number of $10 tickets
Let +c = number of $12 tickets
given:
(1) a+b+c = 400
(1) 8a+10b+12c = 3700
(1) a+b = 7c
--------------
This is 3 equations and 3 unknowns, so
it should be solvable
Substitute (3) into (1)
(1) 7c+c = 400
(1) 8c= 400
(1) c = 50
Plug this value into (2)
(2) 8a+10b+12*50= 3700
(2) 8a+10b+600= 3700
(2) 8a+10b= 3100
(2) 4a+5b= 1550
and
(1) a+b+c= 400
(1) a+b+50= 400
(1) a+b= 350
Multiply both sides of (1) by +4+
(1) 4a+4b= 1400
Subtract (1) from (2)
(2) 4a+5b+=+1550+
(1) -4a-4b= -1400
b= 150
and, since
(3) a+b= 7c
(3) a+150= 7*50
(3) a= 350-150
(3) a= 200
_________________
There are 200 $8 tickets
There are 150 $10 tickets

Each type was sold are 200 for $8, 150 for $10, and 50 for $12 if the ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
At a college production of A Streetcar Named Desire, 400 tickets were sold. The ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.
Let x be the number of $8 tickets
Let y be the number of $10 tickets
Let z be the number of $12 tickets
From the data given in the question, we can frame three linear equation in three variables:
x + y + z = 400
8x + 10y + 12z = 3700
x + y = 7z
After solving the above equations by elimination method:
We get:
x = 200
y = 150
z = 50
Thus, each type was sold are 200 for $8, 150 for $10, and 50 for $12 if the ticket prices were $8, $10, and $12, and the total income from ticket sales was $3700.
