3x = 27
Since 3 is being multiplied by x, we divide both sides by 3.
3x/3 cancels out, and you're left with x.
27/3 = 9
x = 9
This is my take using algebraic methods.
Answer: The minimum score is 77.94.
Step-by-step explanation:
Since we have given that
Mean = 72.7 = μ
Standard deviation = 6.4 = s
Percentage of her students received grades of A = 9%
So, for right tail, we get that
So, z = 0.8186
So, the minimum score would be :
Hence, the minimum score is 77.94.
Y = -2/3x - 1/2 is a linear function because the power of x is 1.
Answer:
B
Step-by-step explanation:
The zeros ( where the graph crosses the x- axis ) are x = 2 and x = 6
The corresponding factors are (x - 2) and (x - 6) and the equation is the product of the factors, so
y = (x - 2)(x - 6) ← expand using Foil
y = x² - 8x + 12 → B
