Answer:
Step-by-step explanation:
Given that a friend flips a coin 10 times and observes head 7 times. So he concludes Probability of head =0.1
This is wrong because
i) Just making 10 trials and coming to conclusion is wrong. Trials should be large to get accurate estimate
ii) The way he threw the coin may be biased so differrent persons should flip and get results for larger trials
iii) External influences such as air, any other disturbance is not considered here.
To avoid all these sampling fluctuations number of trials should be increased with different situations and times.
Step-by-step explanation:
A: 360/5=72
B:540/5=180
C:720/5=144
D:900/5=180
E:1260/5=252
Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular
however
this definition does not apply to the lines y=0 and x=0.
because
The slope of the horizontal line y=0 is equal to zero and the slope of the vertical line x=0 is undefined
Remember that slope is change in y (height) over change in x (horizontal distance). We set up a proportion to find the horizontal distance from the base of the ramp to the end of the truck.
I think x might be 1/2 and y is 1. i believe that is the answer
