The dot plot shows the birth year of everyone who works at Sam’s office. The youngest person who works there was born in 1987. Sam described the data as having a spread from 1965 to 1987, four gaps, a peak at 1984, and a center of 1978. Where did Sam make an error? Birth Year of Employees

A dot plot going from 1965 to 1990. 1966 has 7 dots, 1969 has 2 dots, 1974 has 3 dots, 1975 has 1 dot, 1976 has 3 dots, 1977 has 2 dots, 1977 has 2 dots, 1978 has 5 dots, 1981 has 3 dots, 1983 has 1 dot, 1984 has 8 dots, 1985 has 3 dots, 1986 has 1 dot, 1987 has 1 dot. All other years have 0 dots.
The spread is from 1966 to 1987.
There are 5 gaps.
The peak is at 1985.
The center is at 1977.

answer

a the answer hopes this

step-by-step explanation:

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

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
