What happens if the correlation coefficient equals 0?

1 answer:

3 0

The correlation coefficient represents the strength of a relationship of two sets of data relative to how linear they are. A correlation coefficient of r = 1 would indicate that the relationship was perfectly linear, a correlation coefficient of 0 would mean that they have absolutely no relationship linearly, and are completely dispersed. Hope that makes sense! :) :D

Juanita is 13 years older than her cousin. The sum of their ages is no less than 103 years. Enter an inequality that can be used

Igoryamba

Y = x + 13
y + x ≥ 103
x + 13 + x ≥ 103
Inequality is:
2 x + 13 ≥ 103
2 x ≥ 103 - 13
2 x ≥ 90
x ≥ 90 : 2
x ≥ 45
The youngest age Juanita`s cousin can be is 45.

Given F = 9 5 C + 32, the conversion formula for Fahrenheit to Celsius, solve for C.

Oksanka [162]

Since you are not given any values to plug in, solving for c simple means to isolate c. First, you would subtract 32 from both sides to get F-32=9/5C. Then, you would multiply both sides by 5/9 in order to get 5/9(F-32)=C or 5/9F-160/9=C.

Hope this helps.
