1) A number is chosen at random from 1 to 50. Find the probability of selecting numbers with a last digit of 4.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

x = -5
