Alright!

To solve, all we need to do is <em>subtract the area of the inner circle from the arear of the outer circle.</em>

But first, we need to find the area of both

Key equation: πr²

π = 3.14

Inner cirle area = π13²

π13² = 530.66

Outer cirle area = π21²

I got 21 by adding 8 and 13: both added together makes the radius of the larger circle

π21² = 1,385.74

Now let's <em>subtract. </em>

1,385.74 - 530.66 = 855.08

The area of the blue is = 855.08 yards²

The scores and their percent of the final grade for a statistics student are given. What is the​ student's weighted mean​ score?
Phantasy [73]

Answer:

The student's weighted mean score is 92.2.

Step-by-step explanation:

To find the student's weighted mean scored, we multiply each grade by it's weight.

Grades and weights:

Homework: Grade of 86, weight of 20% = 0.2

Quiz: Grade of 87, weight of 5% = 0.05

Quiz: Grade of 91, weight of 5% = 0.05

Project: Grade of 98, weight of 45% = 0.45

Final Exam: Grade of 88, weight of 25% = 0.25.

What is the​ student's weighted mean​ score?

0.2*86 + 0.05*87 + 0.05*91 + 0.45*98 + 0.25*88 = 92.2

The student's weighted mean score is 92.2.

Most states categorize possession of cocaine charges by weight. Possessing less than a gram will result in the lowest level of f
AleksAgata [21]

Answer:

  Over 2 oz. Class A-II felony

Step-by-step explanation:

One would need to carefully weigh the material.*

  0.06 kg ≈ 2.12 oz

Note that .06 kg is 1 significant figure, so this rounds to 2 oz (1 significant figure). Given the precision of the reported weight, there is insufficient precision to say the amount is actually over 2 oz.

__

If you take the numbers at face value, the suspect is in possession of over 2 oz, so will be charged with a Class A-II felony.

_____

* 2.00 ounces translates to about 0.0567 kg, which rounds to 0.06 kg.
