The time for this z-score is 3.28.
The formula for z-scores is
z = (X-μ)/σ
Using our information, we have
-1.2 = (X-4.6)/1.1
Multiply both sides by 1.1:
-1.2(1.1) = X - 4.6
-1.32 = X - 4.6
Add 4.6 to both sides:
-1.32 + 4.6 = X - 4.6 + 4.6
3.28 = X
Answer:
The answer to your question is: y = -47x + 661
Step-by-step explanation:
Data
m = - 47 I wasn't sure if the slope was -47 or -4.
Point (14, 3)
Formula
(y - y1) = m(x - x1)
Process
(y - 3) = -47(x - 14)
y - 3 = -47x + 658
y = -47x + 658 + 3
y = -47x + 661
Hi!
Whatever we do to the inequality, we have to do it to both sides.
Subtract 14 from both sides
14 - 14 - 3x < -1 - 14
-3x < -15
Divide by -3 on both sides
-3x/-3 < -15/-3
x < 5
Because we divided by a negative number, the equality sign flips.
x > 5
^ the answer
Hope this helps! :)
