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

Answer:
Mindy=191
Amy=299
Step-by-step explanation:
first you want to divide $490 in half to see what each person has. Thats 245 and since Amy has $54 more, you minus 54 from 245 to get 191. So while Mindy has 191, Amy has 299
Answer:
yes!
Step-by-step explanation:
yes this is a proportional relationship because if you take a look at each dry dog food to the wet dog food ratio the key component you are trying to find is the basic 1:x ratio and the x would be 3 in this case because if you see, the dry dog food is 3 times as many as the wet dog food in every single category so therefore yes this is proportional.
hope this helps!
Answer:
Maria's book is 202 pages long, Brandon's book is 146 pages long
Step-by-step explanation:
We can set this up with 2 variables: lets say that Maria's book length is x and Brandon's is y.
We can see that Maria's book is 56 pages longer than Brandon's and can come up with an equation:
x=y+56
We also see that their booklengths add up to 348, and can get:
x+y=348
From here, we solve for x and y. We can use substitution to find y.
x+y=348
(y+56)+y=348
2y=292
y=146
Here we plug in for x:
x=y+56
x=(146)+56
x=202
Therefor we get that Maria's book is 202 pages long, Brandon's book is 146 pages long
