Answer:
9-2=7
Step-by-step explanation:
The range of a data set is the maximum (highest) value/number subtracted from the minimum (lowest) value. So to find the range of this data set, you subtract the largest number 9 by 2 to get the range of 7.
These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)
remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line
the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,
2nd is wrong as well, has only 1 point, the center
3rd is right
4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?
3rd on is answer
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h
