<span>Warren
drove from Townsville </span>à<span> Villaville at 70 miles per hour
and from Villaville to Townsville </span>è<span> 50 miles
per hours
He drove for a total of 12 hours.
=> 70 miles + 50 miles = 120 miles
=> 12 hours
So the unit rate of his driving is 120 miles / 12 hours
=> 120 miles / 12 hours
=> 10 miles / hour
thus, he drove in total for 10 miles per hour.
And probably the 2 towns are about 60 miles away.</span>
The score of 96 is 2 standard deviations above the mean score. Using the empirical rule for a normal distribution, the probability of a score above 96 is 0.0235.
Therefore the number of students scoring above 96 is given by:
To apply a scale to a measure, you have to follow this rule:
Real measure x Scale = Scaled measure
So the drawings will have:
4 x 1/24 = 0'167 feet
6 x 1/24 = 0'25 feet
<span>Windows: 0'167 by 0'25 feet
</span>
<span>12 x 1/24 = 0'50 feet
</span><span>8 x 1/24 = 0'33 feet
</span>Doors: 0'33 by <span>0'50 feet</span>
