Answer: Answer:Median: 10.5Lower quartile: 4Upper quartile: 16Explanation:Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 12 (even)Median = Mean of (6)th and (7)th observations = 10 + 11 divided by 2 = 21/2 = 10.5Therefore the median is 10.5.After writing in ascending or descending order the first and last terms justify the lower and upper limits respectively.They are:Lower quartile: 4Upper quartile: 16Question 2.the lengths of 10 pencils, in centimeters:18, 15, 4, 9, 14, 17, 16, 6, 8, 10Type below:_________________Answer:Median: 12Lower quartile: 4Upper quartile: 18Explanation:Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 10 (even)Median = Mean of (5)th and (6)th observations = 10 + 14 divided by 2 = 24/2 = 12Therefore the median is 12.After writing in ascending or descending order the first and last terms justify the lower and upper limits respectively.They are:Lower quartile: 4Upper quartile: 18Question 3.Make a box plot to display the data set in Exercise 2.Type below:_________________Answer:The above box plot represents the lower and upper quartiles, the median.Explanation:Box plot is drawn using the number line and the rectangle which is drawn above it.The ends of the rectangles say about the lower and upper limits and the middle line indicates the median.Question 4.The numbers of students on several teams are 9, 4, 5, 10, 11, 9, 8, and 6. Make a box plot for the data.Type below:_________________Answer: Explanation:Box plot is drawn using the number line and the rectangle which is drawn above it.The ends of the rectangles say about the lower and upper limits and the middle line indicates the median.Therefore the lower and upper quartiles are 4 and 11 respectively.Median:First, write the observations in ascending order or descending order.The formula to calculate the median is mean of (n/2) and (n/2+1)th observations, for even number of observationsn = 8 (even)Median = Mean of (4)th and (5)th observations = 8 + 9 divided by 2 = 17/2 = 8.5Therefore the median is 8.5.
Step-by-step explanation:
Yes his equations are correct
Answer:
See Explanation
Step-by-step explanation:
<em>The question is incomplete as the input and output values are not given. However, the question can still be solved by assuming both values</em>
Given
In this case;
x represents the input while g(x) represents the output
Now, assume x = 2; Determine the output.
Here we simply substitute 2 for x in the above expression
i.e.
becomes
Similarly, if x = 5
Also, let's assume g(x) = -21; Determine the input
becomes
Solve for x
Answer:
£312
Step-by-step explanation:
Amount spent on 60 jumpers = £120
80% of the jumpers :
0.8 * 60 = 48 jumpers
Sales price for 80% = £8 each
Total = £8 * 48 = £384
The remain at an half price offer :
Half price = £8 / 2 = £4
£4 * (60 - 48)
£4 * 12 = £48
Total sales revenue = £(48 + 384) = £432
Total profit made :
Total sales revenue - purchase price
£432 - £120
= £312
Answer:
x = 1/3
Step-by-step explanation:
Move all terms containing x to the left side of the equation.
8+6x=10
Move all terms not containing x to the right side of the equation
6x=2
Divide each term by 6 and simplify.
Exact Form:
x=1/3
Decimal Form:
x=0.3333333333
Hope this helps!
