So,
The probability of the man having diabetes is 0.6 or 60%. Because we are figuring the probability BEFORE the test is taken that he has the disease, we can disregard the test and its accuracy rate. That rate is 60%, the probability of him having diabetes.
The correct option is D.
Answer:
Andres has 12 stars.
Step-by-step explanation:
- 3 stars - 1 goal
- -3/4 stars - Missed goal
- Scored 5
- Missed 4
3 * 5 = 15
He has 15 stars but then misses 4 goals.
3/4 * 4 = 3
He loses 3 stars becuase he missed 4 goals.
15 - 3 = 12
He ends with 12 stars.
Step-by-step explanation:
$15 initial fee. $2 per hour. $35 limit.
35 - 15 = 20
After the initial fee, he has $20 left.
20 ÷ 2 = 10
He can rent the metal detector for 10 hours.
Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
