Data Input
Simone paid $13 for an initial year's
The renewal rate is $8 per year
Equation
y = 8x + 13
Table
x (number of years renewed) | (total cost in dollars)
0 -> 13 dollars
1 -> 21 dollars
2 -> 29 dollars
3 -> 37 dollars
4 -> 45 dollars
Simply the equation by using cross-multiplication, you get 30=5q
Then you swap sides of the equation, you get 5q=30
Then you divide both sides of the equation by 5
Your answer is q=6
X+12=26, x being the amount spent by Richard <span />
Answer:
Yes, 7.5 and 9.2 are outliers
Step-by-step explanation:
Given the 5 number summary :
Minimum: 1.8
Q1: 3.3
Median: 3.8
Q3: 4.5
Maximum: 9.2
To detect an Outlier use the Relation :
Lower bound : Q1 - 1.5*IQR
IQR = Q3 - Q1 = 4.5 - 3.3 = 1.2
lower bound : 3.3 - 1.5(1.2)
Lower bound = 3.3 - 1.8 = 1.5
Upper bound : Q3 + 1.5*IQR
Upper bound : 4.5 + (1.5 * 1.2)
Upper bound : 4.5 + 1.8 = 6.3
Hence,
1.5≤ x ≤ 6.3
Songs with length 7.5 and 9.2 do not meet the condition and are this outliers
