Answer: 360/36 = 10 degrees
Answer:
x=-5, y=-2
Step-by-step explanation:
10x-9y=-32
2x-10y=10
(2x-10y)*5=10*5
10x-50y=50
(10x-9y)-(10x-50y)=-32-50
41y=-82
y=-82/2
y=-2
10x-9(-2)=-32
10x+18=-32
10x=-50
x=-5

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.
