Answer:
65.45
Step-by-step explanation:
Zscore = (x - mean) / standard deviation
x = score
Percentage below C :
D = 18% ; F = 12%
Sum = 30%
Obtain the Zscore for the proportion below D
P(Z < 0.30) = -0.524
Hence, Zscore = -0.524
Put Zscore = -0.524 in the equation :
-0.524 = (x - 72) / 12.5
-0.524 * 12.5 = x - 72
-6.55 = x - 72
-6.55 + 72 = x
x = 65.45
To receive a grade of C or better, score must be atleast 65.45
Answer:
Multiply numerator and denominator with same number to gwt the answers . There are infinitely many numbers
3/10 × 2/2 = 6/20
3/10 × 5/5 = 15/50
3/10 × 10/10 = 30/100
And so on
The quadrants the point (4.-8) is in is the fourth quadrants
