Answer:
math has:30
game has:26
Step-by-step explanation:
math⇒x
game⇒y
x+y=56
x=y+4
so y+4+y=56 ⇒2y+4=56
⇒56-4 ⇒2y=52⇒y=52/2⇒26
and if y = 26 then x=30
The best predicted weight of a person that is 156 cm is 285.4kg
<h3>We have the regression equation as </h3>
y= 106+1.15
When the adult male is 156 cm tall the weight of this person would be calculated as:
y= 106+1.15*156
y = 106 + 179.4
y = 285.4
Hence we can arrive at the conclusion that the best predicted weight of a person that is 156 cm is 285.4kg
