Answer:
1 . 25 or 5/4 as a fraction
Step-by-step explanation: Hope this helps mark me branliest plssss;)
Let the speed of the water current be v.
total travel time = time to go upstream + time to return downstream to the starting point
Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)
Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
Answer:
x = 2
Step-by-step explanation:
The minimum point of the curve is (2, 0). Hence, axis of symmetry is x = 2
Answer:
(a) Mean = 587
Median = 585
Mode = 590
Standard deviation = 112.54
(b) Mean and median are both appropriate as they are close in value, suggesting that the data is quite symmetric.
Explanation:
All four measures are calculated by inserting simple formulas in Excel. These are shown in the below screenshot of the work file.
