Answer:
- Mean = 16.9
- Mode = 18
- Median = 17.5
Step-by-step explanation:
<u>Given data:</u>
- 18, 19, 16, 18, 14, 17, 18, 15
<u>The data in the ascending order:</u>
- 14, 15, 16, 17, 18, 18, 18, 19
<u>The mean:</u>
- (14 + 15 + 16 + 17 + 18*3 + 19)/8 = 16.9 (rounded)
<u>The median:</u>
- (17 + 18)/2 = 17.5 (the average of middle terms)
<u>The mode:</u>
- 18 (the most repeated number)
I assume that the length of the rectangle is 8 inch more than width .

Answer:
Step-by-step explanation:
<u>The coordinates of E and F are:</u>
<u>Find the slope:</u>
- m = (- 4 - 4)/(2 - 4) = - 8 / - 2 = 4
<u>Use point-slope form and point E:</u>
<u>Convert into slope-intercept form:</u>
- y = 4x - 16 + 4
- y = 4x - 12

Answer:
(4x +5)
Step-by-step explanation:
The square of a binomial is ...
(a +b)² = a² +2ab +b²
We assume that the given trinomial is a perfect square, so we can find the terms of the squared binomial by looking at the square roots of the first and last terms:
√(16x²) = 4x
√25 = 5
So, our first choice of side length for the square is ...
s = (4x +5) . . . . . side length of the square
__
Using the above identity, we can verify that the square of this gives the right area:
A = s² = (4x +5)² = (4x)² +2(4x)(5) +5²
A = 16x² +40x +25 . . . . . . as required
