In degree measure, the angles pi/3,pi/4 , and pi/2 are respectively: A. 60, 45, 90 B. 30, 45, 90 C. 45, 60, 90 D. 60, 30, 90 (al
aev [14]
<span>Solution :-
The value of pi expressed in radians and its equivalent degree is = 180 degree
Hence, the value of pi/3 = 180/ 3 = 60 deg
similarly, the value of pi/3 = 180/4= 45 deg
similarly, the value of pi/2= 180/2= 90 deg
Ans :-
The angles of pi/3, pi/4, pi/ 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.</span>
Answer:
t = -1.862, df = 399, p > 0.05
Step-by-step explanation:
The null hypothesis is the statement which is test for its validity. The decision to accept or reject the null hypothesis is based on the test statistics value. In the given question the null hypothesis is H0 = 34. There is one sample t-test for the testing of null hypothesis. The null hypothesis will be same for each type of one sample t-test. The null hypothesis assumes that the difference between the true mean and comparison value is zero.

Because 8/16=x/10 8 is half of 16 so it is equal to the same amount as 5/10
You can simplify them both down to one fraction 1/2

Answer:
h=A-πr²÷2πr
Step-by-step explanation:
Making h subject
A=2πrh+πr²
A-πr²=2πrh
A-πr²÷2πr=h
h=A-πr²÷2πr
