Answer:
Lisa's team have played 24 home games and 25 away games.
Step-by-step explanation:
Given:
Let represents games played at home.
also represent games played away.
Total number of games played = 49
∴
Now according to given data:
Number of home games won =
Number of away game won =
Total games won =26
Hence
Now multiplying equation 1 by 3 we get,
Now Subtracting equation 2 by equation 3 we get,
Substituting value of x in equation 1 we get.
Hence Lisa's team have played 24 home games and 25 away games.

Step-by-step explanation:
<span>Probability = 0.063
Fourth try = 0.0973
Let X be the number of failed attempts at passing the test before the student passes. This
is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7
and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p)
xp.
The probability P that the student passes on the third try means that there were x = 2
failed attempts or P = nb(2, ; 1, .7) = (.3)2
(.7) = 0.063 . The probability that the student
passes before the third try is that there were two or fewer failed attmpts, so P = P(X ≤
2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0
(.7) + (.3)1
(.7) + (.3)2
(.7) = 0.973 .</span>

hope this helps
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80
