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
(3p)(3p) or 3p x 3p. Cause the exponent means 3p times 3p
Answer:
it would be the cube
Step-by-step explanation:
When you imagine the cube it has 6 faces and 12 edges
Mean of the low is approximately 47.7 Median of the low is 45 and 50 or 47.5
The estimate of the circle would be 12ft
