Answer:
2 days
Step-by-step explanation:
Expected number of days until prisoner reaches freedom=E(x)=?
E(x)=x*p(x)
Where x is the number of days and p(x) is the probability associated with them.
X 1 2 3
P(x) 0.5 0.3 0.2
E(x)=1*0.5+2*0.3+3*0.2
E(x)=0.5+0.6+0.6
E(x)=1.7.
Thus, the expected number of days until prisoner reaches freedom are 2 days.

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Number of 8 pounds before boxes to be removed from cargo = b
Weight in pound of crate to be loaded into cargo = 600 pounds
To achieve a balance , no more Than 400 pounds may be taken off the plane
Hence,
Number of pounds removed must not be more than 400 pounds
(8 pounds * b) ≤ 400
8b ≤ 400
Divide both sides by 8
b ≤ 50
Answer:
$225 = $15 a + $ 10 c
Step-by-step explanation:
Given,
Total price = $225
Cost of concert ticket for adults= $15
Cost of concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Now,
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c
2852.1 rounded to the nearest tenth of a mile is still 2852.1
