In AABC, the measure of A is 108° and the
measure of B is 38° . What is the measure of
C?
Answer:
Should be 34
Step-by-step explanation:
Answer:
∠C=34
Step-by-step explanation:
The interior angles of a triangle add to 180 degrees, so
∠A +∠B+ ∠C=180
We know that ∠A is 108, and ∠B is 38, so we can substitute them in
108+38+∠C=180
Combine like terms by adding 108 and 38
146+∠C=180
Subtract 146 from both sides
∠C=34

The teachers of the two classes want to compare the heights of their students. Which statements about the data sets are accurate? Select three options. Because the sets are symmetrical, the mean should be used to compare the data sets. Because the sets do not contain outliers, the MAD should be used to compare the data sets. Because the sets are not symmetrical, the IQR should be used to compare the data sets. Because the sets contain outliers, the median should be used to compare the data sets. The mean and mode cannot be accurately determined based on the type of data display.
This question is incomplete.

The teachers of the two classes want to compare the heights of their students. Which statements about the data sets are accurate? Select three options.
• Because the sets are symmetrical, the mean should be used to compare the data sets.
• Because the sets do not contain outliers, the MAD should be used to compare the data sets.
•Because the sets are not symmetrical, the IQR should be used to compare the data sets.
•Because the sets contain outliers, the median should be used to compare the data sets.
•The mean and mode cannot be accurately determined based on the type of data display.
Answer:
• Because the sets are not symmetrical, the IQR should be used to compare the data sets.
• Because the sets contain outliers, the median should be used to compare the data sets.
• The mean and mode cannot be accurately determined based on the type of data display.
Step-by-step explanation:
In the above question, we can see that a teacher intends to compare the heights of students from two different classes.
Because the data sets to be obtained would contain heights from different classes the results obtained would be non symmetrical.
Hence the best statistical analysis to use to solve for or to compare a set of non symmetrical data is known as either the Median or an Interquartile range.
It is important to note that a non symmetrical data would most likely contain or include the presence of outliers.

What is the slope of the line that passes through the points (22,-4)(−3,-9)? Write your answer in simplest form.
Answer:
1/5
Step-by-step explanation:
We can find the slope of a line passing through two points by using the following
m = (y2-y1)/(x2-x1)
= (-9 - -4)/(-3 - 22)
= (-9+4)/(-25)
= -5/ -25
= 1/5
The slope of the line that passes through the points (22,-4) and (−3,-9) is calculated using the formula for slope. When calculated, the slope is found to be 1/5
Explanation:The slope of a line passing through two given points can be calculated using the formula: m = (y2 - y1) / (x2 - x1). Here, (x1, y1) and (x2, y2) are the coordinates of the two points.
In the given question, the points are (22,-4) and (−3,-9). When the values are entered into the formula, we obtain:
m = (-9 - (-4)) / (-3 - 22) = -5 / -25 = 1/5
So, the slope of the line passing through the points (22,-4) and (−3,-9) is 1/5.

The City Zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bill was $77.50. If two adults and three children got in for $70.00 then what is the price of an adult's ticket and what is the price of a child's ticket?
Answer:
The price of an adult's ticket is $18.5 and price of a child's ticket is $11.
Step-by-step explanation:
We are given the following in the question:
Let x dollars be the cost of an adult's ticket and y dollars be the cost of a child's ticket.
The cost of three adults and two children tickets is $77.50
Thus, we can write the equation:
[tex]3x + 2y = 77.50[/tex]
The cost of two adults and three children tickets is $70.00
Thus, we can write the equation:
[tex]2x+3y = 70[/tex]
Solving the two equations, we get
[tex]6x+4y-(6x+9y) = 155-210\\\Rightarrow -5y = -55\\\Rightarrow y = 11\\\Rightarrow 2x + 33 = 70\\\Rightarrow x = 18.5[/tex]
Thus, the price of an adult's ticket is $18.5 and price of a child's ticket is $11.

1. 7(3-3x)=84 what is x
2. -7(-4-3m)=112 what is m
3.-182=7(2b-8)+7b what is b
4. -101 = -5(8x-5) -6 what is x
Answer:
1. x=-3
2. m=4
3. -6=b
4. x=3
Step-by-step explanation:
1. 7(3-3x)=84 what is x
- Distribute the 7 using distributive property, which will give you 21-21x=84.
- Add 21 to both sides to aim to isolate the x variable, which will give you -23x=63.
- Divide both sides by the coefficient of x, -23, to finally get x by itself: x=-3
2. -7(-4-3m)=112 what is m
- Distribute the -7 using distributive property, which will give you 28+21m=112. Be wary of negatives.
- Subtract 28 to both sides, which will give you 21m=84.
- Divide both sides by 21 (the coefficient of m) to get m by itself: m=4
3.-182=7(2b-8)+7b what is b
- Distribute the 7 using distributive property, which will give you -182=14b-56+7b
- Add like terms to get -182=21b-56.
- Add both sides by 56, which will get you -126=21b.
- Divide both sides by the coefficient of b, 21, to get b by itself: -6=b
4. -101 = -5(8x-5) -6 what is x
- Distribute the -5 using distributive property, which will give you -101=-40x+25-6. Beware of negatives.
- Add like terms to get -101=-40x+19.
- Subtract both sides by 19 to get -120=-40x.
- Divide both sides by 40 (the coefficient of x) to get 3=x.

Solve the following equation x = 0.8x + 72
Answer:
x=360
Step-by-step explanation:
Multiply both sides by 10
x*10=0.8x*10+72*10
Refine
x*10=8x+720
subtract 8x from both sides
x*10-8x=8x+720-8x
simplify
2x=720
Divide both sides by 2
2x/2 = 720/2
Simplify
x=360
Hope this helped !!!!!
The solution to the equation x = 0.8x + 72 is x = 360.
What is the solution to the given equation?Given the equation in the question:
x = 0.8x + 72
To solve the equation x = 0.8x + 72, we need to isolate the variable "x" on one side of the equation.
x = 0.8x + 72
Start by moving the term 0.8x to the other side of the equation.
Subtract 0.8x from both sides:
x - 0.8x = 0.8x - 0.8x + 72
x - 0.8x = 72
0.2x = 72
Now, divide both sides of the equation by 0.2 to solve for "x":
0.2x / 0.2 = 72 / 0.2
x = 72 / 0.2
x = 360
Therefore, the value of x is 360.

You roll a number cube one time
What is the probability of not rolling a number more than 62 Write your
answer as a fraction.
Answer:
6/6 or 1/1
Step-by-step explanation:
A standard number cube has 6 sides to it. Therefore there are 6 possibilities, as you can roll either a 1, 2, 3, 4, 5, or 6.
The question is asking what the probability is for not rolling a number more than 62. To reword the question to get rid of the confusing 'not', "What is the probability of rolling a number less than 62?"
All the possibilities on the dice are less than 62, therefore it is guaranteed you will not roll a number more than 62. The probability is 1, or written as a fraction 1/1, or 6/6, since 6 sides of the 6 sided cube are less than 62.

The population of a town is increasing at a rate of 2.8% per year. In 2001 the town had a population of 34,229. Find the population of the town in 2013
Answer:
The population of the town in 2013 is 47,677. (to the nearest whole number)
Step-by-step explanation:
To calculate this, we will compare the increase to the increase of the present value of an amount of money invested in 2001, increasing at an annual percentage rate of 2.8%, to yield the future value worth a certain amount in 2013. To calculate, the formula below is used:
FV = [tex]PV ( 1 + \frac{i}{n}) ^{n*t}[/tex]
where:
FV = Future Value = ???
PV = present value = 34,229
i = interest in decimal = 2.8% = 0.028
n = frequency of compounding period per year = 1
t = number of compounding years = 2001 to 2013 = 12 years.
FV = [tex]34,229(1+\frac{0.028}{1} )^{(1*12)}[/tex]
FV = 34,229 × (1.028)¹²
FV = 47,677.29 = 47,677 (to the nearest whole number)

A group of students is timed while sprinting 100 meters. Each student’s speed can be found by dividing 100 m by their time. Is each statement true or false? Explain your reasoning.
Speed is a function of time.
Time is a function of distance.
Speed is a function of number of students racing.
Time is a function of speed.
Answer:
True
Step-by-step explanation:
since, S= D/T the distance traveled would only be 100m, it is a consatnt variable dividing it with the time it takes to reach that distance would be its speed. Unless there is an acceleration happening in that process the speed would change depending on the situation.
Final answer:
Speed is a function of time and time is a function of speed, with these relationships demonstrated through the equations speed = distance/time and time = distance/speed. The number of students racing does not affect an individual's speed.
Explanation:
A student asked several questions related to speed, distance, and time while analyzing a 100-meter sprint. To address these questions, we will look at the relationships between these quantities.
Speed is a function of time: True. Speed can be calculated as the distance traveled divided by the time it took, so if you know the time, you can calculate the speed using the equation speed = distance/time.
Time is a function of distance: False. Time can be a function of speed and distance (time = distance/speed), but this question does not provide information indicating that time is directly dependent on distance alone.
Speed is a function of the number of students racing: False. The speed of a student is independent of the number of students racing; it is determined by the individual's performance (distance/time).
Time is a function of speed: True. Given a constant distance, time can be calculated by dividing the distance by the speed (time = distance/speed).
Colin rolls a fair dice and flips a fair coin.
What is the probability of obtaining a 3 and a tail?
Give your answer in its simplest form.
The probability of Colin getting a 3 on a die and a tail on a coin simultaneously is 1/12, obtained by multiplying the individual probabilities (1/6 for the die and 1/2 for the coin).
Explanation:The probability of obtaining a 3 when rolling a fair dice is 1/6, since a dice has 6 sides and only one of them is a 3. Similarly, the probability of obtaining a tail when flipping a fair coin is 1/2, because a coin has 2 sides, heads and tails.
The probability of both events happening (rolling a 3 and flipping a tail) is the multiplication of their individual probabilities. Hence, the probability is 1/6 times 1/2 equals 1/12.
So, the final simplified form of the probability of Colin rolling a 3 on a die and flipping a tail on a coin, according to the rules of probability, is 1/12.
To find the probability of rolling a 3 and flipping a tail, we need to determine the probability of rolling a 3 on the dice and the probability of flipping a tail on the coin, and then multiply these probabilities together. A fair dice has 6 equally likely outcomes, so the probability of rolling a 3 is 1/6. Similarly, a fair coin has 2 equally likely outcomes, so the probability of flipping a tail is 1/2. Multiplying these probabilities gives us (1/6) * (1/2) = 1/12. Therefore, the probability of obtaining a 3 and a tail is 1/12 in its simplest form.
