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.

Step-by-step explanation:
Solutions of systems are found where the graphs intersect one another. These 2 functions will never intersect, therefore, there is no solution. It is known as inconsistent.
Answer:
(x² -7)/(2x + 1)
Step-by-step explanation:
f(x) = 2x+1 and g(x) = x² -7
thus: (g/f)(x) = g(x)/f(x) = x² -7/2x + 1

Answer:
AB = CD
Step-by-step explanation:
According to the question, data provided is as follows
AB parallel to CD
AC and BD both are perpendicular to AB and CD
Based on the above information, the relationship between AC and BD is
As we know that
Since AC and BD both are perpendicular to AB and CD and these two are parallel. That means they have the same direction as they are parallel
Moreover, in the case of parallel lines, the perpendicular distance between these two lines would remain the same
Therefore
AB = CD
