Answer:
3.5
Step-by-step explanation:
The interquartile range is the difference between the third and first quartile
IQR = Q3 - Q1
From the dot plot given :
The data, X could be culled :
X = 43, 44, 44, 44, 45, 45, 47, 48, 48
n = 9
Q3 = 3/4(n + 1)th term
Q3 = 3/4(10) = 7.5th term = (47 + 48) / 2 = 47.5
Q1 = 1/4(n + 1)th term
Q1 = 1/4(10) = 2.5th term = (44 + 44) / 2 = 44
Q3 - Q1 = 47.5 - 44 = 3.5

m =
Step-by-step explanation:
Answer:
63y * 28x
Step-by-step explanation:
The (Y) which represents the total amount, would be $63 for the first time, and (X) would be an extra $28 per day.
So the graph would be 63y and 28x.
Answer:
This problem involves the very basic formula of representing the total by a variable N. The number of boys plus the number of girls is equal to N but the number of girls is 36% of N.
Writing the representations
N = number of boys + number of girls
N = 48 + 36% of N
N = 0.36N + 48
N - 0.36N = 48
0.64N = 48
N = 48 / 0.64
N = 75
There are 75 people in the class. The number of boys is 48 and the number of girls is 27. The percentage of girls is 36% of 75.
