Answer:
8 and 9
Step-by-step explanation:
8² = 64, and 9² = 81. Equivalently, √64 = 8 and √81 = 9. Since 67 is between 64 and 81, √67 must be between 8 and 9.
Answer:
4.5miles
Step-by-step explanation:
divide 28 by 3 to get 9.333 minutes each mile
then divide 42 by 9.333 to get 4.50 miles
The probability that the the sample mean would be less than x=132.25 will be calculated as follows:
z=(x-σ)/μ
μ- mean
σ- standard deviation
z=(132.25-138)/28=-0.2054
thus:
P(X≤x)=0.4207=42.07%
8 gallons/340 miles vs. 7 gallons/350 miles
$32/340 miles vs. $28/350 miles
$1.133/1 miles vs. $0.08/1 mile
113 cents/mile vs. 8 cents per mile
113 cents- 8 cents = 105 cents
The answer is 105 cents/mile.
Answer:
Step-by-step explanation:
since we don't have any sense of scale any one of the 1st 3 might be right,
here are the vertex locations for the 1st 3
( 1/3, 4/3)
(1,2)
(7/6 , 33/12 )
all three look pretty close... maybe the 2nd one? hmm
