Scatterplot
Pie graph
Line graph
Histogram
Correct Answer : D
In order for the teacher to better visualize the test performance for his class, he needs to present the mark distribution in chart form. A better chart visualizer is the histogram, which will show the frequency of marks against range of test scores. A bar graph will not be used because the rectangles need to touch one another.
In a bar graph, the rectangles do not touch each other. Therefore, it will not be a good chart visualizer.

Let x be the original price of the recliner.
Step 1: Apply the 30% discount
The recliner is on sale for 30% less than the original price:
SalePrice=x−0.3x=0.7x
Step 2: Apply the 25% coupon discount
The consumer gets an additional 25% off the sale price:
FinalPrice=0.7x−0.25(0.7x) = 0.525x
Step 3: Solve for x
The consumer paid $237, so:
0.525x=237
​ x≈451.43x
Rounding to the nearest dollar, the original price is $451.

The median of a data set is found in two ways:
For an odd data set, the median fall in the (N+1)/2 th position.
For an even data set, the median is the average of the element in the (N/2)th and (N+1)/2 th positions.
To find the median of the given data set, we need to arrange the elements from the smallest to the largest as follows:
12, 12, 16, 18, 19, 22, 23, 24, 26, 35, 35
There are 11 elements in the data set. 11 is an odd number and the median fall in the (N+1)/2 th position.
Median =(11+1)/2=12/2=6 th position.
From the organized data, the element in the 6th position is 22, which is the required median for the data set.
