Answer:
558 cm^3
Step-by-step explanation:
V cone = 1/3 pi r^2 h
We know it is 186 cm^3
186 =1/3 pi r^2 h
Multiply by 3
558 = pi r^2 h
V cylinder = pi r^2 h
From above we know that pi r^2 h is 558 , so the Volume of the cylinder is 558 cm^3
Answer:
10.62
Step-by-step explanation:
Mean can be described as the average of a sum of numbers, it can be calculated by sum ing all the numbers together and then diving by the total
The mean of the set of numbers shown in the question above can be calculated as follows
3+4+6+7+10+15+19+21/8
= 85/8
= 10.62
Hence the mean is 10.62
Answer:
3 Credit Courses = 37
4 Credit Courses = 11
Step-by-step explanation:
1. Set up 2 equations:
3x + 4y = 155
x + y = 48
2. Simplify the second expression for x by subtracting y from both sides
x = 48 - y
3. Substitute 48 - y for x
3(48-y) + 4y = 155
4. Simplify the expression by multiplying by 3
144 - 3y +4y = 155
5. Subtract 144 from both sides and subtract 3y from 4y
y = 11 = 4 Credit Courses
6. Substitute y for equation 2
x = 48-11
7. solve for x
x = 37 = 3 Credit Courses
1. Mean of the data: 8
2. Median: 8
3. IQR = 4
4. Members that use the facility 10 days a month is: 2.
See reasons below.
<h3>What is the Mean, Median, and Interquartile Range of a Data?</h3>
Mean = sum of all values ÷ number of data values (easily solved using a dot plot
Median = middle value (easily found using a box plot).
Interquartile range (IQR) = Q3 - Q1 (easily found using a box plot).
1. Mean of the data: use the dot plot.
Reasoning: (3 + 3 + 5 + 6 + 6 + 7 + 8 + 8 + 8 + 9 + 10 + 10 + 11 + 12 + 14)/15 = 8
2. Median of the data set: Using the box plot, it is the value indicated by the vertical line that divides the box.
Median = 8
3. IQR = Q3 - Q1 = 10 - 6
IQR = 4
4. Members that use the facility 10 days a month, using the dot plot is: 2. 10 has 2 dots.
