What t value will yield 4?
H(t) = 4t + 20
How about -4?
H(-4) = 4(-4) + 20
H(-4) = -16 + 20
H(-4) = 4
Yes, t = -4
Done.
Answer:
0.216
Step-by-step explanation:
If the probability of green, P(green) is 40%, the probability of red, P(red) is 60%.
The probability of a light being red is not affected by the colour of the previous light, so at each of the 3 lights, the probability of red is always 60%.
To find the probability that all three lights will be red, multiply the three probabilities together. (Convert them to decimals first).
0.6 x 0.6 x 0.6 = 0.216
Answer:
To the tenth = 2.8
Step-by-step explanation:
