20.50+36.21=56.57
Twice can be said as x2 so
20.50 x2=41
Leaving 56.57 and 41
56.67+41=91.67
Answer: Hi the Range is 4
Step-by-step explanation: The range of a data set in statistics is the difference between the largest and the smallest values. While range does have different meanings within different areas of statistics and mathematics, this is its most basic definition, and is what is used by the provided calculator. Using the same example:
18, 16, 19, 15, 17
<u><em>19</em></u>,18,17,16,<u><em>15 </em></u>
19-15= 4
W=12.5c+39.2
Her collection already has a weight of 39.2 g so you must add that to every new car bought each with a weight of 12.5 g.
3/4 of an hour = 45 minutes
45 * 3 = 135 minutes
135 + 45 = 180 minutes
He spends 180 minutes or 3 hours
