Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x/3 - 2
f(42) is x = 42
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(42) = 42/3 - 2
- Divide: f(42) = 14 - 2
- Subtract: f(42) = 12
Answer:
500 x 70 = 35000chips
burnt chips : 35000 x 3 /50 = 2100
Step-by-step explanation:
The normal distribution curve for the problem is shown below
We need to standardise the value X=405.5 by using the formula
We now need to find the probability of z=0.32 by reading the z-table
Note that z-table would give the reading to the left of z-score, so if your aim is to work out the area to the right of a z-score, then you'd need to do:
from the z-table, the reading
gives 0.6255
hence,
The probability that the mean weight for a sample of 40 trout exceeds 405.5 gram is 0.3475 = 34.75%
