The average score for the entire year is 88.44444, so by rounding down the answer is 88%
F(x) = 4x - 1. You can get this by using the slope formula and then point-slope form.
1. The slope of f(x) is twice as steep as that of g(x).
2. The y intercept of g(x) is much greater than that of f(x) because 8>-1
Answer:
as posted: 0.18182
more likely: 2.00
Step-by-step explanation:
z = (x -μ)/σ
... = (90 -76)/77 = 14/77 = 2/11
z ≈ 0.18182
_____
We know that cutting and pasting often results in numbers being unintentionally repeated, so your 77 may be intended to be 7. In that case, the z-score is
... z = (90 -76)/7 = 14/7
z = 2
