Fiona has to plot a histogram of the given data.

82, 83, 89, 67, 65, 88, 66, 69, 83, 81, 94, 68, 82, 69, 86, 83, 88, 62, 64, 93

which frequency table should she use for the histogram?
a.
interval 60-70 70-80 80-90 90-100
frequency 8 0 10 2
b.
interval 56-63 63-70 70-77 77-84 84-91 91-98
frequency 1 7 0 5 5 2
c.
interval 50-70 70-80 80-85 85-90 90-100
frequency 8 0 6 4 2
d.
interval 60-75 75-90 90-105
frequency 8 10 2

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
