Select the correct answer from each drop-down menu.
Which data set has a wider spread? Why?
Set A: {9, 11, 24, 11, 4, 20, 16, 7, 18, 15, 28, 6}
Set B: {9, 12, 15, 3, 21, 24, 5, 9, 16, 21}
has a wider spread because .

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

if x decreases by 4 then y increases by 10

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
