<h2>Question:</h2>

At Priscilla's school, the final grade for her Calculus course is weighted as follows: Tests: 50% Quizzes: 30% Homework: 20% Priscilla has an average of 87% on her tests, 100% on her quizzes, and 20% on her homework. What is Priscilla's weighted average?

<h2>Work:</h2>

Weighted Average gives weights to each percent of the average as follows:

Weighted Average = Average * weighting percent

Weighted Average = Test Average * Test Weighting + Quiz Average. * Quiz Weighting + Homework Average * Homework Weighting

Weighted Average = 87% * 50% + 100% * 30% + 20% * 20%

Weighted Average = 43.5% + 30% + 4%

Weighted Average = 77.5%

<h2>Answer:</h2>

77.5%

The equation of a circle is given below.
BARSIC [14]

<u>Given</u>:

The equation of the circle is x^2+(y+4)^2=64

We need to determine the center and radius of the circle.

<u>Center</u>:

The general form of the equation of the circle is (x-h)^2+(y-k)^2=r^2

where (h,k) is the center of the circle and r is the radius.

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the center.

The given equation can be written as,

(x-0)^2+(y+4)^2=64

Comparing the two equations, we get;

(h,k) = (0,-4)

Therefore, the center of the circle is (0,-4)

<u>Radius:</u>

Let us compare the general form of the equation of the circle with the given equation x^2+(y+4)^2=64 to determine the radius.

Hence, the given equation can be written as,

x^2+(y+4)^2=8^2

Comparing the two equation, we get;

r^2=8^2

 r=8

Thus, the radius of the circle is 8

Help me pleaseeee ???
Leokris [45]
There's only one solution...the one you get when you divide both sides by 22 to solve for x.  902/22 = 41.  That exponent on the x, the one you don't see, is a "1" which tells us that there is only 1 solution to this problem.  If your x is squared, then you have 2 solutions; if it's cubed, you have 3, etc.

Find the mean and median of 1,1,2,2,2,2,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5
svetoff [14.1K]

Answer:

Mean - 3.3793103448276

Median - 3

Step-by-step explanation:

<u>Define:</u>

Mean ⇒ Average

Median ⇒ Middle Number

<u>Solve:</u>

Mean ( Adding all number then divide by total number in data set)

1 + 1 + 2+2+2+2+3+3+3+3+3+3+3+3+3+4+4+4+4+4+4+4+4+5+5+5+5+5=94

94/29 = 3.3793103448276

Mean - 3.3793103448276

Median ( Find Middle Number)

1,1,2,2,2,2,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5
