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).
640 divided by 5 is 128, therefore it’s 128 calories
Who to do with numbers . at least put some signs in there .
Answer:
$63
Step-by-step explanation:
well 35 divided by 5 is 7 so 7 hr a day and 7 x 9 is 63 so $63 per day
The value of the coefficient B will be 9.
<h3>What will be the value of B in equation written below?</h3>
2(x+By)(x-2y)
=2(x^2 -2xy +Bxy -2By^2)
=2x^2 -4xy + 2Bxy - 4By^2
The original form is 

hence the value of B=9
