7/24.3 is your simplified answer.
Answer:
Step-by-step explanation:
Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.
If you are trying to find the length of the sides of the squares, the formula is
Area = side^2
3025 = side^2
Take the square root of both sides.
sqrt(3025) = sqrt(side^2)
To find the square root of 3025, do the following
Press √
type in 3025
type in =
You should get 55.
======================
The second square is done the same way
√
90.75
=
And you should get 9.526

The FBI investigates civil right violations
Answer:
Highest area) Student's t-Distribution with 30 degrees of freedom
Middle) Student's t-Distribution with 50 degrees of freedom
Lowest are) Standard deviation distribution
Step-by-step explanation:
Knowing that higher area of the tails correspond to higher dispersion of the t- distribution, and the following properties of t-distribution:
- when the degrees of freedom increase , the dispersion diminishes
- when the degrees of freedom goes to ∞ , t- distribution approaches the standard normal distribution ( thus the z-curve is known as t-curve with df=∞ )
the correct answer is
Tail area : standard deviation < 50 df < 30 df
