Bryce wrote the linear regression equation y= 1. 123x-6.443 to predict the armspan, y, of a person who is x inches tall. riley has an armspan of 67.5 inches. which is the best prediction of riley’s height?

I am writing THe given equation is y = 1.123x -6.443 where y represents the armspan and x represents the height . Now we need to find the height , when armspan = 67.5 inches. SO we need to plug 67.5 for y and solve for x that is

67.5 = 1.123x -6.443

adding 6.443 to both sides

67.5 +6.443 =1.123x

73.943 = 1.123x

Dividing both sides by 1.123

x = 65.84 inches .

So for the given armspan of 67.5 inches, height is 65.84 inches .

Step-by-step explanation:

got it right

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
