Answer: 0.0766
Step-by-step explanation:
Let x be the random team scores.
Given: Mean = 76
Standard deviation = 8.4
We assume that x follows normal distribution.
The probability that a random team scores less than 64 points = P(x<60)

Hence, the probability that a random team scores less than 64 points =0.0766

Hope this helps!
3(y + 3) + 5y = 4(2y + 1) + 5
...multiply
3y + 9 + 5y = 8y + 4 + 5
...simplify
8y + 9 = 8y + 9
...the equation is true, so the answer is infinitely many solutions
