Step-by-step explanation:
use FOIL
(20+2.5)x = cost
when x equals number of tickets
(20+2.5)24 = 540
Answer:
The probability of losing weigth given that the sandwich was ordered is 80%.
Step-by-step explanation:
The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:
sandwich and losing weigh = (ordering sandwich)*losing weigth
losing weigth = (sandwich and losing weigth)/(ordeing sandwich)
losing wiegh = 40%/0.5 = 80%
The probability of losing weigth given that the sandwich was ordered is 80%.
Answer:
n = -6 or n = 4.
Step-by-step explanation:
-3 | -8n – 8 | = -120
Divide both sides by -3:
| -8n – 8 | = 40
This gives us 2 equations because the expression in the absolute signs can be positive or negative:
-8n - 8 = 40
so -8n = 48
n = -6.
and
-8n - 8 = -40
-8n = -32
n = 4.
