Answer:
8.80
Step-by-step explanation:
(S. D.)^2=summation(x-mean)^2/(n-1)
S. D.=sqrt(388/5)
S. D.=8.80
For the first one:
The radian of 60º is 1.047. you just have to find one that has the same value, which would be 
/3. (the last choice).
for the second one:
you do it the other way. The answer is 45 degrees.
The anwer would be 276,000 because 5 or up u round something lower than 5 it stays the same and the numbers behind it turn into zero's
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
