3 x (2)³ is an expression that's equal to 24 .
Answer:
when x equals -3 y equals -23
when x equals 0, y equals -8
when x equals 3, y equals 7
when x equals 6, y equals 22
Step-by-step explanation:
Answer:
Its a right isosceles triangle
The answer would be y=-3/4x-3
P(at least 5 rolls until 1) = P(4 rolls are not 1) = 5/6 x 5/6 x 5/6 x 5/6 = 0.4823 (4sf)
Fewer than 7 rolls to get second 1 after first takes 3 rolls means second occurs on 4th, 5th or 6th roll
The probability of each of these is 1/6, 5/6 x 1/6 and 5/6 x 5/6 x 1/6 respectively.
P(second 1 on 4th, 5th or 6th roll) = 1/6 + 5/36 + 25/216 = 91/216 = 0.4213 (4sf)
