IQR means middle or in this case it is 2
Week #1 : 12 hours
Week #2 : 480/60 = 8 hours
Week #3 : 6.5 hours
Week #4 : 750/60 = 12.5 hours
total = 39 hours for all four weeks
in the 4th week she read the most
Answer:
616/2500
Step-by-step explanation: You first have to find the number of times a Blue marbles was chosen: 22
Then find the total number of marbles that were chosen. Make a fraction out of it: 22/50
You then see how many times tails was flipped: 28
Do the same thing again: 28/50
Then multiply the two fractions together:
22/50 * 28/50 = 616/2500
Step-by-step:
Use slope formula to find the slope. (y - y)/(x - x)
Make sure the x and y in front of the minus is a pair that goes together, as well as the x and y behind the minus sign. So
8 - -4 goes on top, that's 12
0 - -1 goes under, thats 1
12/1 is the slope which is just 12. Use either point to fill in the second x and the second y in the point-slope equation. m is the slope.
y - y = m(x - x)
y - 8 = 12(x - 0)
y - 8 = 12x
Answer:
$75
Step-by-step explanation:
if 255 is three times a normal pair of shoes than you divide 255 by three cause it is inverse operations
hope it helps!
