Assume symmetry.
Then
length of opposite side of angle a, L=((4.265-2.84)/2) =>
sin(a)=L/8.53
=((4.265-2.84)/2)/8.53
=0.08353
=>
a=asin(0.08353)
=4.79 degrees
Answer:
83.85%
Step-by-step explanation:
We will use the empirical rule. For a standard normal distribution the mean is equal to 0 and the standard deviation is equal to 1. Then, between 3 standard deviations below the mean, we have 2.35% + 13.5% + 34% = 49.85% of data, and 1 standard deviation above the mean we have 34% of data. Therefore, the percentage of data that are between 3 standard deviations below the mean and 1 standard deviation above the mean is 49.85%+34% = 83.85%.
Answer:
a = 50 b = 50
Step-by-step explanation:
a. 35/65=0.53 - rounded to the nearest tenth would equal to 50.
b.
65-35=30
30/65 = .46
rounded to the nearest tenth equals to 50.
Hope this helps!
Answer:
r=9
Step-by-step explanation:
45/360=1/8
1/8*2=2/8
2/8=1/4
1/4*pi*r=(9pi)/4
Divide both sides by 1/4 (the fours cancel each other out)
Pi*r=9*pi
Pi cancels each other out
R=9
Hope this helps
Answer:
The answer is both.
Step-by-step explanation:
It is both because 8^{2} is 64 and 4^{3} is 64.
