If 2.2 pounds = 1 kilogram and Mary weighs 120 pounds, how much does she weigh in
kilograms?

Answers

Answer 1
Answer:

Final answer:

To convert a weight in pounds to kilograms, you divide the weight in pounds by 2.2. So, if Mary weighs 120 pounds, her weight in kilograms would be about 54.54.

Explanation:

First, you need to know that the conversion factor between pounds and kilograms is 2.2 pounds = 1 kilogram. This means if you want to convert a weight in pounds to kilograms, you should divide the weight in pounds by 2.2.

In Mary's case, she weighs 120 pounds. To find her weight in kilograms, you simply divide 120 by 2.2, which equals approximately 54.54 kilograms.

Therefore, Mary's weight in kilograms is roughly 54.54 kg.

How many points of intersection will the following system of linear equations have? y = 9x, 3y = -3x - 5 a) 0 b) 1 c) 2 d) Infinite

Answers

Answer:

b

Step-by-step explanation:

given the system of equations

y = 9x → (1)

3y = - 3x - 5 → (2)

substitute y = 9x into (2)

3(9x) = - 3x - 5

27x = - 3x - 5 ( add 3x to both sides )

30x = - 5 (divide both sides by 30 )

x = - (5)/(30) = - (1)/(6)

substitute x = - (1)/(6) into (1) and solve for y

y = 9x = 9 × - (1)/(6) = - (9)/(6) = - (3)/(2)

point of intersection = ( - (1)/(6), - (3)/(2) )

Given the box plot, will the mean or the median provide a better description of the center? a. The Mean, because the data distribution is symmetrical

b. the median, because the data distribution is symmetrical.

c. the mean, because the data distribution is skewed to the right.

d. the median, because the data distribution is skewed to the right

Answers

From the given box plot we can see that there are more values towards the right end than are on the left end.

This means the data is skewed towards right. A symmetrical box plot has same number of values on both sides of the median.

Whenever we are dealing with skewed graphs, the best option to choose from mean and median is always the median. This is because due to large number of data values on the one side, the mean will always be closer to that side. Median is not largely affected in this case.

Therefore, the correct answer would be option D.
The median, because the data distribution is skewed to the right
D. Mean always goes toward the skewness due to outliers.
Median is minimally affected by outliers.
