You substitute the equation and see if it works. Also, the first one that you answered is wrong.
Answer: $48
Step-by-step explanation: The amount of money Joe made can be divided by 9. 54/9 = 6. Joe made 9 dollars six times so Leila made 8 dollars 6 times. 6 x 8 = 48.
Answer:
a=b
Step-by-step explanation:
An antisymmetric relation () satisfies the following property:
If (a, b) is in R and (b, a) is in R, then a = b.
This means that if a|b and b|a then a = b
If a|b then, b can be written as b = an for an integer n
If b|a then a can be written as a= bm for an integer m
Now we have b = (a)n = (bm)n
b = bmn
1 =mn
But since m and n are integers, the only two integers that satisfy this property would be m = n = 1
Therefore, b = an = a (1) = a ⇒b = a
Answer:
, 
and volume of cerebral brey matter for a child whose head circumference Z score at age 12 months was 1.9 is 
Step-by-step explanation:
We attached a table below,
We attached a table below,
Therefore ,
correlation coefficient 
We calculate the least squares equation.
Now , calculate intercept coefficient.
Therefore, the regression equation is,
