The owner of a sporting goods store gathered data about the numbers of men's, women's and children's bicycles sold each month. She used a
graphing tool to organize the data in different scatter plots and found these lines of best fit:
Answers
Answer:
The answer A
Step-by-step explanation:
The average correlation is close to The relationship between the number of men's, x and the number of women's, y bikes sold hence, it is a line of best fit so, option A is correct.
What is a line of fit?A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.
Given:
The owner of a sporting goods store gathered data about the numbers of men's, women's, and children's bicycles sold each month,
The relationship between the number of men's, x and the number of women's, y bikes sold is molded by the equation, y = 0.95x + 0.83, and the correlation coefficient is 0.791,
The relationship between the number of men's, x, and the number of children, y bikes sold is molded by the equation, y = 0.87x + 0.98, and the correlation coefficient is 0.564,
The relationship between the number of children x and the number of women's bikes sold is molded by the equation, y = 0.73x + 0.91, and the correlation coefficient is 0.945,
As you can see that the average of the correlation coefficient is,
Average = 0.791 + 0.564 + 0.945 / 3
Average = 2.3 / 3
Average = 0.77
Thus, the correlation 0.791 is the line of best fit.

Answer:
1/2
Step-by-step explanation:
bc 4/10 + 1/10= 5/10 divided by 2 =1/2
Answer:
1/2 or 5/10
Step-by-step explanation:
When you are adding fractions you only add the numerator (the top number) 4+1=5. So you get 5/10. But then you have to divide to get the simplest form. You can divide 10 and 5 by 5. So then after you are done dividing you end up with 1/2!

Marissa wrote her bike to the park and back up halfway to the park she stopped at the library she was one 310 miles from the library how many miles and miles to ride her bike and all now
Answers
Answer:
5 1/5 miles
Step-by-step explanation:
Given that :
Library is located halfway between park and home ;
Distance between library and park = 1 3/10 miles
Hence, total distance between park and home :
1 3/10 + 1 3/10 = 2 6/10
The distance driven :
Home to park ; park back home
2 6/10 + 2 6/10 = 4 12/10
4 + 12/10 = 4 + 1 2/10
= 5 2/10
= 5 1/5 miles
