The route will take four hours and fifteen minutes. If you start at 9:50 and count four hours, you'll get to 1:50, add ten to get to 2:00, then add 5 minutes to get to 2:05. Four hours plus ten minutes plus five minutes, 4:15.
Original balance $1,018.00
Desk cost -$84.00
Computer cost -$372.00
Savings from job +$44.00
Current balance = $606.00
Amount to be added to get original balance:
1018 - 606
= $412.00
Answer:
d. The variance is 9.56 and the standard deviation is 3.09.
Step-by-step explanation:
From the above question, we are given the following data set.
3, 7, 8, 8, 8, 9, 10, 10, 13, 14
a) Mean = 3 + 7 + 8 + 8 + 8 + 9 + 10 + 10 + 13 + 14/ 10
= 90/10
= 9
b) Variance
The formula for sample Variance = (Mean - x)²/ n - 1
Mean = 9
n = 10
Sample Variance =
(3 - 9)² + (7 - 9)² + (8 - 9)² + (8 - 9)² + (8 - 9)² + (9 - 9)² + (10 - 9)² + (10 - 9)² + (13 - 9)² + (14 - 9)² / 10 - 1
= 36 + 4 + 1 + 1 + 1 + 0 + 1 + 1 + 16 + 25/9
= 86/9
= 9.555555556
≈ Approximately 9.56
Variance = 9.56
Sample Standard deviation = √Sample Variance
= √9.56
= 3.0919249667
≈ Approximately 3.09
Answer: 38
Step-by-step explanation:
There is a rule between operations. I mean that you have to follow these stpes:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
You can remember as "Please Excuse My Dear Aunt Sally" or PEMDAS.
In this question: 5x5+2.8÷2.2+3.3= 25+16÷4+3=25+4+9=38
