Answer: Justin dirty laundry was reduced by 74. 18%
Step-by-step explanation:
Step 1
Total amount of clothes = 124 pieces
Number of clothes reduced to = 32 pieces
To find the amount of the reduction, We will first Subtract the number reduced to from the initial amount of clothes giving us
Amount of reduction = 124- 32 =92 pieces of clothes
Step 2---Then we Divide the amount of the reduction of the clothes by the total amount of clothes to find the rate of reduction, giving us
Rate of reduction = 92/124 = 0.741
Step 3--- we finally Multiply the rate of reduction of clothes by 100 to find the percentage reduction.
0.741 x 100 = 74. 18%
Answer:
B. The Interquartile Range (IQR) for the Bulldogs, 20, is less than the IQR for the Tigers, 25
Step-by-step explanation:
The question is asking for a comparison of spread. There are two methods for measuring spread, that are standard deviation and the Interquartile Range. For a skewed box plot like this one you would use the Interquartile Range. The 5 numbers on a box plot are part of the 5 number summary. From left to right the numbers above the box plot are the minimum, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum. To find IQR you just subtract the third quartile (Q3) from the first (Q1). In this case, for the Bulldogs the IQR= 90-70+=20 and for the Tigers IQR=85-60=25.
