Step-by-step explanation:
Way 1, final price
<u>Apply discount and then apply tax</u>
- (50 - 20%) + 10% =
- 50*0.8*1.1 =
- $44
Way 2, final price

- (50 + 10%) - 20% =
- 50*1.1*0.8 =
- $44
As we see both ways reveal same final price so no difference
Answer:
P = 0.041553
Step-by-step explanation:
Probability that a student considers calculus exciting. = 0.84
Probability that a student finds calculus not exciting = 0.16
This is a binomial experiment.
p = 0.84 and n = 29
The probability of observing 28 or more of the students who consider calculus to be an exciting subject in our sample of 29 is given by:
P = 0.041553
