Answer:
9.6e-5
Step-by-step explanation:
First, add together the costs for buying their own stuff. 250+135+69+25=479.
Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
Using correlation coefficients, it is found that the measures have a correlation, but it is not strong.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem:
- Correlation of -0.52 indicates that they have a negative correlation.
- Since |-0.52| < 0.6, the correlation is not strong.

Stock A: 400 × 3 = $1,200
Stock B: 500 ÷ 2 = $250
$1,200 - $250 = $950
