Answer:
52.64
Step-by-step explanation:
to find the range you add all the numbers and then you divide the total by the amount of numbers you have
44 +27 + 83 + 56 + 75 + 25 + 50 + 41 + 56 + 89 + 33 = 579 divide by 11 = 52.64
The smaller the value of the least increment, the more precise a number is.
Length measured to the nearest 1/8 inch will be more precisely specified than length measured to the nearest 1/4 inch.
_____
In general, precision has little to do with accuracy—how close the measured value is to the actual value. A measurement can be very precise, but just plain wrong. (Many electronic instruments have resolution (precision) that exceeds their accuracy. That is, one or two (or more) of the least-significant displayed digits may be in error.)
1 day = 24 hours
58 days = (24)(58) = 1392 hours
60 mins = 1 hour
30 mins = 30/60 hour = 1/2 hour
Total hours Keurig takes to complete a full rotation = 1392 + 15 + 1/2 = 1407(1/2) hours.
Answer:
1. the shape on the left had been enlarged with a scale factor 10 to give the shape on the right - all the lenghts are 10 times longer e.g AZ is 8, corresponding WZ is 80
2. corrseponding angles are equal
