Answer:
The pumpkin weight is 190.4 pounds
Step-by-step explanation:
We are trying to find the weight of the pumpkin
Let x be the weight of the pumpkin
We know the cost per pound = .45, the total cost 93.68 and the delivery fee =8
The total cost = the delivery fee plus the cost per pound * number of pounds
Substitute in what we know
93.68 = 8 + .45*w
Subtract 8 from each side
93.68-8 = 8-8 +.45w
85.68 = .45w
Divide each side by .45
85.68/.45 = .45w/.45
190.4 = w
The pumpkin weight is 190.4 pounds
Answer:
128 ft/s; it represents the average speed of the object between 2 seconds and 6 seconds
Step-by-step explanation:
The average rate of change is another way to say slope.
slope = (y2-y1)/(x2-x1)
= (576-64)/(6-2)
= (512/4)
=128 ft/s
This represents the change in ft per second, or the average speed the object is going during the time period.
Answer:
- p(12 are truthful) ≈ 0.0687
- p(≥ 1 are not) ≈ 0.9313
Step-by-step explanation:
The probability the test says 1 is truthful is 0.8, so the probability that all 12 will be judged truthful is ...
0.8^12 ≈ 0.0687
The probability that at least one will be judged untruthful is the complement of this:
1 - 0.0687 = 0.9313
The probability that the lie detector says all 12 are truthful is about 0.0687.
The probability that lie detector says at least 1 is deceptive is about 0.9313.
