PQ = 2 units
height = 4 units
area = 2*4 = 8/2 = 4 square units
Answer:
0.03125
Step-by-step explanation:
If we have a fair coin the probability of landing a head is 50%.
We can think the question as what is the probability of landing four tails and then a head. That is we needed at least 5 tries to get a head.
Since this events are independent we can write it as
The coordinate is a solution for the first system (x-2y=4). But the coordinate is not a solution for the second system.
Roughly one and a half hours in
99% confidence limits
for population proportion is:
CL = P +- Z * √(P*(1-P)/N))
Where:
P = sample proportion
Z = Z-score taken at 99%
confidence = 2.575
N = sample size
Calculating for the
values:<span>
P = 350/500 = 0.7
N = 500 </span>
Substituting know values
to the CL equation:
<span>CL = 0.7 +- 2.575* </span>√<span>(0.7*(1-0.7)/500))</span>
<span>CL = 0.647 , 0.753</span>
<span>
</span>
<span>Therefore confidence limits range from 0.647 to 0.753.</span>
