Answer:
Step-by-step explanation:
By using regression line calculator,
Equation of the regression line from the data given,
y = -0.38993x + 26.95184
Here, y = weekly hours of sport
x = Time to run
For x = 50 minutes,
y = -0.38993(50) + 26.95184
= 7.45534
≈ 8
Since, slope of the given regression line is negative, correlation will be negative (n).
The answer is negative twenty five. By the way, if that is you in the picture, you are beautiful.

Answer:
There are 180 marbles in the jar
Step-by-step explanation:
Let x = number of marbles in the jar
x * 25% = number of red marbles
x * .25 = 45
Divide each side by .25
x *.25/.25 = 45/.25
x =180
There are 180 marbles in the jar
