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
<span> f(3) = f(2) + f(1) => 3 + 2 = 5
f(4) = f(3) + f(2) => 5 + 3 = 8
f(5) = f(4) + f(3) => 8 + 5 = 13
Therefore the sequence is 2, 3, 5, 8, 13,.....a Fibonacci sequence.

Answer:
198
Step-by-step explanation:
If you take any 3-digit number and change the numbers around and subtract them you will always get 198.
Answer:
The 4th graph
Step-by-step explanation:
To determine which graph corresponds to the f(x) = \sqrt{x} we will start with inserting some values for x and see what y values we will obtain and then compare it with graphs.
f(1) = \sqrt{1} = 1\\f(2) = \sqrt{2} \approx 1.41\\f(4) = \sqrt{4} = 2\\f(9) = \sqrt{9} = 3
So, we can see that the pairs (1, 1), (2, 1.41), (4, 2), (3, 9) correspond to the fourth graph.
Do not be confused with the third graph - you can see that on the third graph there are also negative y values, which cannot be the case with the f(x) =\sqrt{x}, the range of that function is [0, \infty>, so there are only positive y values for f(x) = \sqrt{x}
