Answer:
b. 85
Step-by-step explanation:
Average grade (μ) = 75
Standard deviation (σ) = 8
Assuming a normal distribution, the z-score corresponding to the upper 10% of the test grades is z = 1.28.
The minimum grade 'X' within the top 10% is given by:
Rounding to the nearest percent, the dividing point between an A and a B grade is 85.
-6x + 2y = 2
Answer:
x = 2, y =7
Step-by-step explanation:
4x - 2y = -6
-6x + 2y = 2
Add the equations together
4x - 2y = -6
-6x + 2y = 2
-----------------------
-2x = -4
Divide each side by -2
-2x/-2 = -4/-2
x = 2
now find y
-6x+2y =2
-6(2) +2y =2
-12+2y =2
Add 12 to each side
-12+12+2y = 2+12
2y =14
Divide by 2
2y/2 =14/2
y =7
Answer: 4/12 is closer to 0

Step-by-step explanation:
Answer:
(0, -2) (Answer B)
Step-by-step explanation:
Recall that the y-axis represents x = 0. The blue line crosses (intercepts) the y-axis when x = 0. The corresponding y-coordinate is -2. Thus, the y-intercept is (0, -2), or just -2.
