A: 20,529, 22,081, 21,454, 21,449, 21,801, 21,892, 20,913, 20,075, 21,694, 21,681, 21,416, 21,829, 21,013, 22,053 B: 4.02, 4.71, 3.87, 4.57, 4.29, 4.49, 3.23, 2.94, 4.41, 3.07, 3.23 Step 2 of 2 : Which of the above sets of sample data has the smaller spread?

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
