Answers

Answer:

A prediction based on the data is reliable, because the means of the samples are close together.

Step-by-step explanation:

Test approved

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given three data sets.

All the samples have 10 data points.

Number of data points = 10

Mean of sample 1 = 9.1

Mean of sample 2 = 9.4

Mean of sample 3 = 8.9

We can see that the mean of the three samples is so close to each other.

So the data is reliable.

Hence the option is A.

The area of the Pacific Ocean is about 6.0061 x 10^7 square miles. The area of the Southern Ocean is about 7.8483 x 10^6 square miles. Approximately how many times larger is the area of the Pacific Ocean than that of the Southern Ocean?

Answers

Answer:

7.653 larger

Step-by-step explanation:

Pacific area/Southern area = (6.0061) * 10^7 / (7.8483) * 10^6

= 6.0061/ 7.8483 * 10^7/10^6

= 0.7653 * 10^(7-6)

= 0.7653 * 10^1

= 0.7653 * 10

= 7.653

Compared to the Southern Ocean, the Pacific Ocean is about 7.653 times larger.

Is Mary a guy? :|

Step-by-step explanation:

I did this by just a good guess , not really the right way

2000*.45=900 ( 900 is the old savings)

2000*.2 =400 ( how much her salary went down by )

2000-400=1600 ( new salary )

1600*.45 = 720 ( 45% of new salary is new savings

900-720=180 ( change in savings is 180 , the amount the question asks for)
