11.2*5 = 56
10.1*4.2 = 42.42
Difference: 56-42.42
= 13.58
Answer:
x = 162 cards need to be dealt with
Step-by-step explanation:
Given:
- Estimation of likelyhood of next card to be queen, a king, or an ace:
( 64 - 0.2*x ) / ( 208 - x )
Find:
For what values of x is this likelihood greater than 70%?
Solution:
- Use the likely-hood estimation relation and set up the inequality as follows:
( 64 - 0.2*x ) / ( 208 - x ) > 0.7
( 64 - 0.2*x ) > 0.7*( 208 - x )
64 - 0.2*x > 145.6 - 0.7*x
0.5*x > 81.6
x > 163.2
- It would require 162 cards to be dealt with for the probability of next card being queen, a king, or an ace is greater than 70%
Answer:
275
Step-by-step explanation:
t = total sold
c = cheeseburgers h = hamburgers
c + h = t total is equal to cheeseburgers + hamburgers
we know that
c + h = 481
and that c = h - 69
so we can rewrite the first equation as
(h-69) + h = 481
2h = 481 + 69
2h = 550 h=550/2=275
so there 275 hamburgers were sold
