From the given above, we calculate for the total cycle time by adding up all the durations given for the yellow light, red light, and green. That is,
total time = 30 s + 10 s + 50 s = 90s
Hence, the total time is equal to 90 s. From this, we calculate for the probability that the first light that will be seen is a red light by dividing the duration of the red light in the cycle by the total time.
Probability = (30 seconds) / (90 seconds)
= 1/3
Therefore, the probability that the red light will be seen first is equal to 1/3. The answer is second choice.
H(-2) = 2(-2)^2 - 3(-2)
= 2(4) - (-6)
= 8 + 6
= 14
Answer:
1.172 dollars per pound
Step-by-step explanation:
Given : A pet supply store sells a 20-pound bag of dog food $23.44.
To Find :Find the unit price.
Solution :
Cost of 20-pound bag of food = $23.44
So, Cost of 1-pound bag of food = 
= 
For unit price we should divide the cost by no. of pounds
So, the error is you have divided the no. of pounds by cost
Hence the unit price is 1.172 dollars per pound
