Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2
Hope this helps!
Answer: C
the mean and the median
Step-by-step explanation:
From the attached table,
The range of group A = 5 - 0 = 5
The range of group B = 4 - 1 = 3
Difference in range is not equal to $1
The mode of A = 1
The mode of B = 3
Difference in mode is not equal to $1
The median of A = (1 + 2)/2 = 1.5
The median of B = 3
Difference = 3 - 1.5 = $1.5
The mean of A = 16/15 = 1.07
The mean of B = 40/15 = 2.67
The difference = $1.6
From the above analysis, we can therefore conclude that non of the measures are $1 greater for Group B than for Group A
The best option among the options is
the mean and the median
Answer:
-x^2 +12x +5
Step-by-step explanation:
x^2+3x + -2x^2+9x+5
I like to line them vertically
x^2+3x
-2x^2+9x+5
