Answer:
Option B. Range of the given sample data is 113.
Step-by-step explanation:
The given question is incomplete; here is the complete question.
Find the range for the given sample data.
The amounts below represent the last twelve transactions made to Juan's checking account. Positive numbers represent deposits and negative numbers represent debits from his
account.
$28 -$20 $67 -$22 -$15 $17 -$38 $41 $53 -$13 $30 $75
Option A. $75
Option B. $113
Option C. $37
Option D. -$113
Transaction done by Juan can be arrange from lowest to highest
-38 -22 -20 - 15 -13 17 28 30 41 53 67 75
Now we know rage of the sample data = Highest value - Lowest value
= 75 - (-38)
= 113
Therefore, range of the given sample data is 113.
Option B is the answer.
Answer:
u = 12
Step-by-step explanation:
The equation is showing 5(u) = 60
<u>Begin: 5(u)= 60</u>
2. Divide the 5 from both sides to get the u-value alone.
a) 5u/5 = u b) 60/5 = 12
<u>Now: u = 12</u>
Answer: 10 miles
Step-by-step explanation:
Practically, just look at it. 30 minutes = 5 miles, 60 minutes = 10 miles
Mathmatically, find the constant of proportionality.
- 30 minutes divided by 5 miles = 6 minutes per 1 mile.
- 60 minutes = 10 miles
The answer would be 0.1 because the first decimal place is tenths, then hundredths, then thousandths, etc.
