Answer: The probability of this ocurring by chance is less than 0.01.
The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.
Step-by-step explanation:
Since we have given that
Number of times a coin tossed = 500
Number of times head occurs = 416
So, our Z-score would be

So, At significance level of 0.01, p-value of Z-score is .202704.
and p-value < 0.01, i.e. 0.202704<0.832.
Hence, the probability of this ocurring by chance is less than 0.01.
The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.
<span>b – 2a – c
= 9 - 2(-3) - (-6)
= 9 + 6 + 6
= 21

Answer:
the cubes are 1 in on all sides
but...
since there's gaps its more likely that there a 1/2 in or 3/4 in
Step-by-step explanation:
12/12=1
Okay
now draw a right angled triangle
labeling the hypotenus 57ft
the opposite x and the adjacent 5.5 ft and the angle in the right angle triangle is 55 °.
now solve
sin 55°=x/5.5
0.8192(the sin of 55)= x/5.5
cross multiply
X=4.51
