According to Forbes, the average age of millionaires in the US 10 years ago was 62 years old. Since then, the number of millionaires in the US has grown to over 17 million. One prevalent belief among
economists is that the average age of millionaires today has decreased from the average age of
millionaires 10 years ago. To investigate this belief, a random sample of 50 millionaires from the US was
selected and their ages were recorded. Here are the summary statistics.

Based on this sample, is there convincing evidence that the true mean age of millionaires in the US is
less than 62 years old? Use a = 0.01. Provide statistical evidence to support your answer.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
