Step-by-step explanation:
Answer:
So total cost of tickets = $64
Step-by-step explanation:
Given:
Cost of adult = $12
Cost of Children = $7
Total Adults = 3
Total children = 4
To Find:
Total Cost = ?
Solution:
We are given per person price and no of persons too now
Total cost = Cost of children ticket + Cost of Adults ticket
Now we will find the values
Cost of 3 adults ticket = total person * cost per person
= 3 * 12
=$36
Cost of 4 Children ticket = total person * cost per person
= 4 * 7
=$28
Now
Total cost = Cost of children ticket + Cost of Adults ticket
putting value
Total cost = 28 + 36
= $ 64
So total cost of tickets = $64
Answer:
D. 30
Step-by-step explanation:
Having a population that doesn't follow normal distribution (skewed) can still have sampling distribution that is completely normal. This fact is presented in the Central Limit Theorem.
Central Limit Theorem: states that we can have a normal distribution of sample means even if the original population doesn't follow normal distribution, we just need to take a large sample.
So how much sample size do we need?
There is no straight forward answer to this rather we have to analyse the situation closely!
1. If the population distribution is already normal then a smaller sample size would be enough to ensure normal distribution.
2. If the population distribution is very skewed than a larger number of sample size is needed to ensure normal distribution. The rule of thumb is to take sample size equal to or more than 30 to be on safer side. This is the case in this problem hence option D fits the best.
Answer:
B
Step-by-step explanation:
It cannot be D, because it costs way more, it cannot be C because there are other options that provide better value. We can finally determine that it is B because for 3 pens more it is only 9 cents more
