Answer:
a. 47.6mph (distance divided by time = speed. divide each rowers distance by their speed, then add them all)
b. 1.26 minutes per mile (i used a calculator so i dunno how to explain)
let me know if this is right or not :)
Answer: 296 or 592
Step-by-step explanation:
Answer: x=1
y=2
Step-by-step explanation:
y=-x+3
y=4x-2
-----------
y=y
-x+3=4x-2
3+2=4x+x
5=5x
x=1
y=-1+3
y=2
Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
Answer:
The most absolute error is 12
Step-by-step explanation:
The formula for absolute error is given by the following relation;
Absolute error, Δx = Value measured, x₀ - Exact (actual) value, x
Δx = x₀ - x
Since the actual count is between 77 and 89, the maximum absolute error will be where the actual value = 77 and the measured value = 89 and vice versa, giving an absolute error of 89 -77 = 12.
The most absolute error = 12.
