Given thatP(5,4) Q(8,10) and R (X,18) are collinear. Find X

aleksley [76]

Answer:

x = 12.

Step-by-step explanation:

If P(5,4),Q(8,10) and R(x,18) are collinear

then the slope of PQ equals the slope of QR

hence:

(10 - 4)/(8 - 5) = (18 - 10)/(x - 8)

6/3= 8/(x - 8)

2 = 8/(x - 8)

multiplying both sides by (x - 8) gives:

2(x - 8) = 8

2x - 16 = 8

2x = 8 + 16 = 24

hence x = 12

The histogram is in attached file.

Step-by-step explanation:

The width of class interval=range/desired number of classes

The width of class interval=(maximum-minimum)/7

The width of class interval=(200-10)/7

The width of class interval=190/7

The width of class interval=27.14=28 (rounded to next whole number)
