Answer:
The parcel with weight less than 20.14 pounds are 99% of all parcels under the surcharge weight.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12 pounds
Standard Deviation, σ = 3.5 pounds
We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.99
Calculation the value from standard normal z table, we have,
Thus, parcel with weight less than 20.14 pounds are 99% of all parcels under the surcharge weight.
Answer:
a = -8
Step-by-step explanation:
-5⁄2 a + 5 = 25
Subtract 5 from each side
-5⁄2 a + 5-5 = 25-5
-5/2 a = 20
Multiply each side by -2/5 to isolate a
-2/5 * -5/2 a = -2/5 *20
a = -8
