During the first 11 months of a recent year, a certain charitable organization received an average (arithmetic mean) of $20,600

Aleks04 [339]

Answer:

D. $25,400

Step-by-step explanation:

Let x represent the score during December.

We have been given that during 1 months of a recent year, a certain charitable organization received an average (arithmetic mean) of $20,600 per month in donations.

The total score for 11 months would be $11\times 20,600=226600$ .

We can set our given information in an equation as:

$\text{Average}=\frac{\text{Sum of all data points}}{\text{Total number of data points}}$

$\frac{226,600+x}{12}=21,000$

$\frac{226,600+x}{12}*12=21,000*12$

$226,600+x=252,000$

$226,600-226,600+x=252,000-226,600$

$x=25,400$

Therefore, the organization received $25,400 in donations during December and option D is the correct choice.

Write an equation for an ellipse centered at the origin, which has foci at (\pm5,0)(±5,0)(, plus minus, 5, comma, 0, )and vertic

Virty [35]

Answer:

The equation of ellipse is

$\frac{x^2}{41}+\frac{y^2}{16}=1$

Step-by-step explanation:

The equation of an ellipse is

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

where(h,k) is the center and c is distance from the center to the foci is given by $a^2-b^2=c^2$ . a is the distance from the center to the vertices and b is the distance from the center to the co-vertices.
