Answer: A) y+6=3/4(x+4)
Once this equation is simplified, it becomes y=3/4x-3, which is the equation of the line.
You would cross multiply.
5x=6(2/3)
5x=4
x=4/5
or
x=0.8
The answer is 80 because you divide 32 by 2/5

Answer:
The correct answer is - 97.74%.
Step-by-step explanation:
Given:
sample mean = 281
Std Dev = 47 ==> Sample
Std Dev (s) = std dev/sqrt(n) = 6.0677
Solution:
Find : P( x > 268 )
z = ( x - u )/s = ( 268 - 281 )/6.0677
= -1.9558
then, P( x > 270) = P( Z > -1.9558)
= P( Z <1.9558)
= 0.9747
change into percentage:
= 97.471%
