Step-by-step explanation:
find the attachment showing std normal curve symmetrical about y axis.
Equal probabilities on either side of the mean thus the total probability to the right of mean is 0.50
From the table we can find that
a) P(Z>2.5) = 0.5- area lying between 0 and 2.5
= 0.5-0.4938 =0.0062
b) P(1.2<z<2.2) = F(2.2)-F(1.2)
= 0.9861-0.3849
=0.6012
For this case we have the following data:
Available quantity: $ 24
Regular price: r
Sale price:
If we have that Roopesh can not pay more than $ 24, we can write the following inequality, taking into account that the item is sold in :
Clearing r:
Answer:
- What is the unknown?
- Which expression can represent the sale price?
- Which comparison could be used?
The sale price decreases $ 5 and so the regular price is obtained.
- The inequality is:
