Hello!
First you have to find the total of the items he bought
382 + 12 + 6.14 = 400.14
Then you apply the tax rate
400.14 * 1.0825 = 433.15155
We round this to 433.15
The answer is $433.15
Hope this helps!
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
To answer this we will find the unit rate by dividing. Lets do it:-
10.43 ÷ 7 = 1.49
1 pound of grapes = $1.49
CHECK OUR WORK:-
1.49 × 7 = 10.43
we were RIGHT!!!
Now lets multiply to see how much 3 pounds would cost.
1.49 × 3 = 4.47
CHECK OUR WORK:-
4.47 ÷ 3 = 1.49
We were RIGHT!!
So, 3 pounds of grapes cost $4.47.
Hope i helped ya!!
