Answer:
(-1,1)
Step-by-step explanation:
x + 9y = 8
-6x - 9y = -3
Add the two equations together to eliminate y
x + 9y = 8
-6x - 9y = -3
---------------------
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = -1
Now solve for y by substituting into the first equation
x+9y = 8
-1 + 9y =8
Add 1 to each side
-1+1 + 9y = 8+1
9y=9
Divide each side by 9
9y/9 = 9/9
y = 1
We will use Binomial Distribution in this case.
Since the coin is tossed 15 times. N which is the number of trails will be 15.
P = Probability of heads
Q = Probability of tails
X = No. heads occurring in each toss.
So, now we have to find the probability for exactly 10 heads.
P(x = 10) = C(15, 10) P^x Q^N-x
C(15, 10) (1/2)^10 (1/2)^5 = 0.0916

You are asked to find the team score, so it is convenient to let a variable represent that value. Let's call it "s", for "score". The problem statement tells you
.. Michaela scored s/5 . . . . . one fifth of the team's points
.. Aleah scored s/10 . . . . . . . one tenth o the team's points
These scores together are (s/5 +s/10) and that amount is 42 points.
.. s/5 +s/10 = 42
.. s(2/10 +1/10) = 42 . . . . . factor out s
.. s(3/10) = 42 . . . . . . . . . . form the sum of the numbers in parentheses
.. s = 42*10/3 = 140 . . . . . multiply by the inverse of the coefficient of s
The team scored 140 points.
______
Michaela scored 140/5 = 28 points; Aleah scored 140/10 = 14 points.
