Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2

Answer:
Mean= Summation /number of terms
= 48/8
=6.
Median
To do this
arrange all terms from smallest to biggest
That is
2,4,4,5,7,8,9,9
The two middle numbers are
5 and 7.
To get the median
add both and divide by 2
5+7 = 12... 12/2 =6
Median=6
Mode.... This is the number that appears most
Mode = 4 and 9.(Bimodal) Both appear equally.
Range: Highest - Lowest
= 9-2 =7.

Answer:
x= -5
Step-by-step explanation:3x-7=5x+3, subtract 3x from both sides, you get -7=2x+3, subtract 3 from both sides you get -10=2x. divide both sides by 2 and you get x= -5
