Abox contains 40 number tiles numbered 1 to 40. if a tile is drawn at random, what is the probability that the number drawn is a multiple of 3 or 4? find p(multiple of 4 or multiple of 5)

Multiples of 3 are 3, 6, 9, ... 39, or 3*1, 3*2, ,,,3*13, so there are 13 of them.

Multiples of 4 are 4*1 pto 4*10, or 10 of them

Multiples of both 3 and 4 are 3*4*1 to 3*4*3,

or 12, 24, 36, 3 of them.

Multiples of either 3 or 4 are 3, 4, 6, 8, ..., 40,

13+10-3 = 20 of them.

P(multiple of either 3 or 4) = 20/40 = 0.5

P(multiple of 4 or 5) = (10+8-2)/40 = 16/40 = 0.4

Step-by-step explanation:

(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

answer: -0.5 would be the most likley outcome
