Answer:
1) 30
Step-by-step explanation:
We need the radius of the wheel, we know that the radius is half the diameter, therefore:
r = d / 2 = 3/2 = 1.5
the angle is equal to the distance traveled (s) divided by the radius, thus:
° A = s / r =
° A = 45 / 1.5
° A = 30 radians
Through the radiation angle of 30 radians the wheel turned
therefore the answer is 1) 30
The radian angle at which the wheel rotated is; 1: 30
What is the angle of rotation?
We are given;
Diameter of wheel; d = 3 ft
Radius; r = d/2 = 3/2 = 1.5 ft
Now, the formula for the radian angle at which the wheel rotated is;
θ = s/r =
where;
s is distance
r is radius
Thus;
θ = 45/1.5
θ = 30 radians
Thus the angle at which the wheel rotated is 30 radians

You are running late, but still have a chance to make it to that important meeting on time. It normally takes 24 seconds to get from the first floor to your normal third floor, but you have to get to the fourteenth floor. You have 3 minutes to get there. Will you get there on time? How many minutes early or late will you be? (Round to the nearest hundredth if necessary.)
Answer:
3+11+ 14
24x11=264
264sec=4.4 minutes
youll be late by 1min 40 sec
Given that it takes 12 seconds to reach each floor, you will reach the 14th floor in 156 seconds. Compared to the total time available (180 seconds), you will be 24 seconds (or 0.4 minutes) early to your meeting.
Explanation:To solve this problem, we need to determine how long it takes for you to reach each floor. If it takes you 24 seconds to reach the 3rd floor from the 1st floor, we can infer that it takes you 12 seconds to reach each floor (24 seconds/2 floors). Therefore, to reach the 14th floor from the first, it would take 12 seconds times 13 floors which equals 156 seconds.
Then, we need to convert the time given to get to the meeting, which is 3 minutes, into seconds (3 minutes * 60 seconds/minute = 180 seconds).
Subtract the required time to reach the 14th floor (156 seconds) from the total time available (180 seconds), and you will be 24 seconds early for your meeting (or 0.4 minutes, rounding to the nearest hundredth, if the time is converted back into minutes).

The average hourly charge of plumbers in the Denver area is $84.00 with a standard deviation of $4.00. Assume that the hourly charges of the plumbers in Denver are normally distributed. If a person living in Denver calls a random plumber, what is the probability that the plumber will charge at least $86.00 per hour. Express your answer as a decimal between 0 and 1, to the nearest hundredth.
Answer:
The probability is 0.31
Step-by-step explanation:
In this question, we are tasked with calculating the probability that a random plumber called at Denver will charge an amount greater than $86 given the mean and the standard deviation.
Firstly, we calculate the standard score of $86 using the mean and the standard deviation.
Mathematically;
z-score = (x-mean)/SD
where x = 86, mean = 84 and SD = 4
z-score = (86-84)/4 = 2/4 = 0.5
Hence, we want to calculate P(z ≥ 0.5)
Using standard table
P( (z ≥ 0.5) = 1 - P(z ≤ 0.5) = 1 - ( 0.19146 + 0.5) = 0.30854
To the nearest hundredth = 0.31

Zelda has 8 rabbits with which to start an animal farm. If the rabbit population doubles each month, in how many months will the rabbit population be 5,800?
Answer:
9.5 months
Step-by-step explanation:
We would be using the expression
y = abⁿ
Where
a = starting number = 8 rabbits
b = rate of change = the number of rabbits doubles = 2
n = number of time intervals that has passed = unknown = number of months
y = rabbit population = 5800
y = abⁿ
5800 = 8 × 2ⁿ
Divide both sides by 8
5800 ÷ 8 = 2ⁿ
725 = 2ⁿ
n = 9.5 months.
Therefore, the number of months in which the rabbit population would reach 5,800 is 9.5 months

How many times did we buy a school lunch last week?
How many days were in the last month?
Is your favorite number 5?
Answer: The correct option is the first question; How many times did we buy a school lunch last week?
Step-by-step explanation: When collecting data for the purpose of statistics and data analyses, the exercise involved goes beyond just asking questions. It is actually about asking questions that would provide data or information with a measure of variability. That would help in deciding which data can be best suited to represent the entire data collected.
The question how many days were in last month is not a statistical question because the answer is pretty much straight forward. The number of days in the previous month cannot vary, it will always be the same, hence the answer would be not be useful for any kind of statistical analyses.
Also, asking "Is your favorite number 5?" is not a statistical question because the answer is a yes or no. This does not allow for any kind of statistical analyses. Its as good as a 'dead end.'
However, asking how many times we bought a school lunch last week is a statistical question because the data collected would have a good measure of variability. That is, the data cannot be the same for all respondents. Unlike in the second question where the answer is already known and unchangeable, the answer to this question is not going to be a fixed one and as the respondents provide varying answers, you can now begin to measure the point at which all the answers are likely to agree (measure of central tendency) which is a basic part of statistics.

Number of combinations of taking x items out of total n items
ⁿCₓ = n!/x!(n-x)!
Given,
Number of girls in group = 12
Number of boys in group = 10
Selecting 3 boys from the group
= ¹⁰C₃
= ¹⁰C₃
= 10!/3!(10 - 3)!
= 10!/3!×7!
= (10 × 9 × 8 × 7!)/(3 × 2 × 1 × 7!)
= 10 × 3 × 4
= 120
Selecting 4 girls from group
= ¹²C₄
= 12!/4!(12 - 4)!
= 12!/4!×8!
= (12 × 11 × 10 × 9 × 8!)/(4 × 3 × 2 × 1 × 8!)
= 3 × 11 × 5 × 3
= 495
Total number of committees of 3 boys and 4 girls formed from the group
= ¹⁰C₃ × ¹²C₄
= 120 × 495
= 59400

Sebastian has 3 whole apples. He cuts each whole into fourths. Sebastian gives away 4 4 of the apples. Which is the number of fourths Sebastian has left as a fraction?
Answer: He now has eight-fourths of the apples left.
Step-by-step explanation: If Sebastian has three whole apples and now decides to cut each apple into fourths, that is four parts, then the total number of fourths he has left can be derived as follows;
1 apple = 4 parts
3 apples = 3 x (4 parts)
3 apples = 12 parts
If Sebastian gives away four of the apples, we can now express this as;
Remainder = 12 parts - 4 parts
Remainder = 8 parts
What Sebastian had was fourths and no longer whole apples, hence from our calculation, Sebastian has eight-fourths (8 quarters, or 8 fourths) left as a fraction of his apples.
Final answer:
Sebastian cuts 3 apples into fourths, giving him 12 pieces. He gives away 4 pieces, leaving him with 8 fourths of an apple. The number of fourths left expressed as a fraction is 8/4.
Explanation:
Sebastian starts with 3 whole apples and cuts each into fourths, resulting in 3 x 4 = 12 pieces. After giving away 4 fourths of the apples, we subtract 4 from the original 12 pieces to answer the question: Which is the number of fourths Sebastian has left as a fraction?
To find out how many fourths are left, we compute 12 - 4 = 8 fourths. This can be simplified to the fraction 8/4, which equals 2 whole apples. However, since the question asks for the answer in the form of a fraction representing the fourths, we should write our final answer as 8/4.
If we were to simplify the fraction to show the number of whole apples instead of fourths, we would say that Sebastian has 2 whole apples left.

A map has a scale 1 inches : 10 miles. Use the given map distance to find the actual distance.
1. 3 in 2. 7.5 in 3. 1 ft
Answer:
1) [tex]x = 30\,in[/tex], 2) [tex]x = 75\,mi[/tex], 3) [tex]x = 31\,mi[/tex]
Step-by-step explanation:
The actual distances are computed below:
1) The actual distance is:
[tex]x = \frac{3\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 30\,in[/tex]
2) The actual distance is:
[tex]x = \frac{7.5\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 75\,mi[/tex]
3) The actual distance is:
[tex]x = \frac{3.1\,in}{1\,in}\times 10\,mi[/tex]
[tex]x = 31\,mi[/tex]
To find the actual distance, multiply the map distance by the scale factor. The scale factor is the ratio of the actual distance to the map distance.
Explanation:To find the actual distance using the given map scale, you need to multiply the map distance by the scale factor. The scale factor is the ratio of the actual distance to the map distance. In this case, the scale factor is 10 miles per inch.
For 3 inches, the actual distance would be 3 inches * 10 miles/inch = 30 miles.For 7.5 inches, the actual distance would be 7.5 inches * 10 miles/inch = 75 miles.For 1 ft, you need to convert feet to inches. There are 12 inches in a foot, so 1 foot = 12 inches. The actual distance would be 12 inches * 10 miles/inch = 120 miles.Learn more about Finding actual distance using a map scale here:https://brainly.com/question/34970123

There are 12 red marbles and 8 green marbles in a bag. What is the probability of selecting a red
marble, not replacing it, and then selecting a green marble from the bag?
Answer:
The probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95
Step-by-step explanation:
Number of red marbles = 12
Number of green marbles = 8
Total number of marbles = 12+8 = 20
Probability of selecting red marble =[tex]\frac{12}{20}[/tex]
Since it is the case of no replacement
Remaining marbles = 20-1 = 19
Number of red marbles = 12-1=11
Number of green marbles = 8
Probability of selecting green marble =[tex]\frac{8}{19}[/tex]
So, the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag =[tex]\frac{12}{20} \times \frac{8}{19}=\frac{24}{95}[/tex]
Hence the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95
