The final probability is the weighted average of the playing probabilities calculated over the possible weather options:
P(john practices cello; given that it rains) * P(it rains) +
P(john practices cello; given that it does not rain) * P(it does not rain) =
0.6 * 0.7 + 0.4 * 0.3 = 0.54
The probability is 54%

Answer:
79+94+91+92+test5)/5=90
The lowest score have to be 94
Step-by-step explanation:
Our goal is gona be to have an average of 90, it can be higher but we are going to use this.
For average the equation is
(test1+test2+test3+test4+test5)/5=average
We know the result for the first 4 tests
Test 1=79
Test 2=94
Test 3=91
Test 4=92
But we dont know test 5
(79+94+91+92+test5)/5=average
Our goal for the average is 90
(79+94+91+92+test5)/5=90
79+94+91+92+test5=90*5
test5=450-79-94-91-92
Test5=94
Answer:
118.7 yards
Step-by-step explanation:
You didn't ask a question
Did you want the length of the diagonal line?
-----------------------------------
d² = 64² + 100²
d² = 4,096 + 10,000
d² = 14,096
Take the square root of both sides
d = 118.7265766372
Rounded
118.7 yards
