slope formula ^^
Numerical expressions use numbers and algebraic expressions use variables.
Answer with explanation:
It is incorrect to say that 50% heritability of intelligence means that the cause of the intelligence is 50% genetic and 50% environmental.
<em><u>Because heritability accounts for variations among people, not in specific individuals which means that the cause is not 50% environmental or 50% genetic but rather based on variations among individuals</u></em>
First step, divide 6 from both sides.
t/6=r^2+1
second step, subtract 1 from both sides
t/6 -1=r^2
Now take the square root of each side.

Done!
Answer:
The answer to your question is the big dog weighs 120 pounds
Step-by-step explanation:
Data
big dog = b
medium dog = m
small dog = s
Equations
b = 5s
m = 12 + s
s = 2/3 m
Process
1.- Substitute m in the last equation
s = 2/3(12 + s)
s = 24/3 + 2/3s
s - 2/3s = 8
1/3 s = 8
s = 8(3)
s = 24 pounds
2.- Substitute s in the first equation
b = 5(24)
b = 120 pounds
