The weight distribution of parcels sent in a certain manner is normal with meanvalue 12 pounds and standard deviation 3.5 pounds

tino4ka555 [31]

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:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.99

$P( X < x) = P( z < \displaystyle\frac{x - 12}{3.5})=0.99$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 12}{3.5} = 2.326\\\\x = 20.141\approx 20.14$

Thus, parcel with weight less than 20.14 pounds are 99% of all parcels under the surcharge weight.

Taylor is using money from her coin try to go to the fair. She wants to spend no more than $17 there. She has $8 in bills and so

ZanzabumX [31]

There are 4 quarters in dollars. Keep that in mind.

Since Taylor is spending no more than 17 dollars, she probably only has 17 dollars. We already know that she has 8 dollars in bills, so we can subtract 8 dollars from 17 dollars because we need to find the amount of dollars in quarters.

The answer for that is 9 dollars. Since there are 4 quarters in the dollars, you need to multiply 9 by 4 to find the amount of quarters.
