13.
Step-by-step explanation:
12.
6a(a + 3) = 2a(3a + 5) + 16
First, distribute 6a on the left side, and distribute 2a on the right side.
6a² + 18a = 6a² + 10a + 16
Subtract 6a² from both sides.
18a = 10a + 16
Subtract 10a from both sides.
8a = 16
Divide both sides by 8.
a = 2
13.
The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.
Combine like terms on the left side. Distribute the 2 on the right side.
Subtract 2x from both sides.
Divide both sides by 3.
Answer: 3) 0.8493
Step-by-step explanation:
Given : Red Bull GmbH (the parent company) has observed that daily sales are normally distributed with an average of 7,421,143 drinks sold with a standard deviation of 6,974.621.
i.e.
Let x denotes the daily sales .
Then, the probability that on a given day below 7,428,350 drinks are sold would be :
Hence, the correct answer is 3) 0.8493
