Multiple Answers
Step-by-step explanation:
We know that the mean is 35 and the median is 31.2 hours.
- Step 2: If we clear n of the percentil formule of the 6th percentile:
(n)(
)= 24 families → n=400 families.
- Step 3: true. The half of the population is 200. Therefore the 50% of the sample(the 50th percentile) is under or equal 31.2
- Step 4: By definition the median is the 50th percentil. So the 50 percentil → 31.2.
- Step 1: If we considerate that the 50th percentil is 31.2, a bigger percentil had to be bigger too.
- Step 5: False. At the beggining we have that the 6% of the population were below or equal to 20 hours, therefore the 25% of the data have to be greater or equal to 20.
Answer:
25% or 0.25
Explanation:
Based on the given conditions, formulate: 2 divided by 8

The statements that apply to the algebraic expression are
- Replace “a number” with the variable, n.
- The two operations are multiplication and subtraction.
- The constants are 2 and 6.
- The expression is written as 2(n – 6)
<h3 /><h3>How to determine the algebraic expression?</h3>
The complete question is added as an attachment
The statement is given as:
Twice the difference of a number and six
Represent the number with n.
So, the statement becomes
Twice the difference of a n and six
Twice means 2 *
So, we have
2 * difference of a n and six
Express difference as minus i.e. -
So, we have
2 * (n - 6)
Hence, the expression is written as 2(n - 6)
