This means the gradient is 4x.
The y intercept is where the line crosses the y axis. We can see this is at -3.
<h2>Rule: <u>y = 4x -3</u></h2>Substitute your values to check if it's right.
y = 4x -3
5 = 4(2) - 3
5 = 8 - 3
5 = 5
1 = 4(1) - 3
1 = 4 - 3
1 = 1
Answer:
82.62
Step-by-step explanation:
Mean score (μ) = 80
Standard deviation (σ) = 5
The 70th percentile of a normal distribution has an equivalent z-score of roughly 0.525.
For any given score, X, the z-score can be determined by:
For z = 0.525:
A raw score of approximately 82.62 corresponds to the 70th percentile.
