Mean mode median range please help me

Mathematics
1 answer:
Anit [1.1K]3 years ago
7 0

Answer:

Mean = 44.

Mean is the average.

Add all numbers:

(43 × 3) + (44 × 5) + (45 × 2) + 46

(129) + (220) + (90) + 46

= 485

Divide by number of points:

485 ÷ 11 = 44.090909 (09 repeating)

Round to 44.

Median = 44

Median is the middle-most number.

Line all the values up:

43, 43, 43, 44, 44, 44, 44, 44, 45, 45, 46

'Cross' numbers off from each side until you reach the middle- 44.

Mode = 44

Mode is the number that appears most often. 43 appears three times, 44 appears five, 45 appears twice, and 46 appears once. Five was the greatest reoccurrence. Therefore, 44 is the mode.

Range = 3

Range is the distance between the smallest value and the largest value.

Smallest number: 43

Largest number: 46

46 - 43 = 3

Find the center and the radius of the circle with the equation:
nekit [7.7K]

Answer:

(x+1)^2 + (y-1)^2 = 16

And the general formula for a circle is given by this expression:

(x-h)^2 +(y-k)^2 = r^2

With the center (h,k) and the radius r. If we compare this general expression with the formula that we obtain in (1) we see that :

h = -1, k =1 , r =4

So then the best solution for this cae would be:

b. center: (-1,1)

radius =4

Step-by-step explanation:

For this case we have the following equation given:

x^2 +2x + y^2 -2y -14=0

And we can complete the squares for this case like this:

x^2 +2x +(2/2)^2 +y^2 -2y +(2/2)^2 =14 +1+1

(x^2 +2x +1) +(y^2 -2y +1) =16

Now we can rewrite the last expression like this:

(x+1)^2 + (y-1)^2 = 16

And the general formula for a circle is given by this expression:

(x-h)^2 +(y-k)^2 = r^2

With the center (h,k) and the radius r. If we compare this general expression with the formula that we obtain in (1) we see that :

h = -1, k =1 , r =4

So then the best solution for this cae would be:

b. center: (-1,1)

radius =4
