Answer:
5 miles
Step-by-step explanation:
distance = speed · time
Tom's distance = (50 mi/h)·(2.5 h) = 125 mi
Albert's distance = (65 mi/h)·(2 h) = 130 mi
Albert drove 130 -125 = 5 miles farther than Tom.
Answer:
x = ± 
i
Step-by-step explanation:
subtract 64 from both sides
9x² = - 64 ( divide both sides by 9 )
x² = - 
( take the square root of both sides )
x = ± 
= ± i
Answer:
Can you post 4.3? We need more information to answer this.
Step-by-step explanation:
45, 51, 52, 58, 61, 63, 66, 72, 74
You're trying to find the second quartile (Q₂), and to find that, you must find the median, and then find the median within the second half of the median :)
Median (Middle Number) : 61
Now, look at 61, and look at 74. What is the median of those numbers in this set?
Q₂ = 66
So, your quartile 2 is 66.
