Step-by-step explanation:
area of circle= πr²
3.14×7×7
153.86 is the required area
G(x) = h(x) +3 . . . . . h translated upward by 3 units
g(x) = (-3x² +3) +3
g(x) = -3x² +6 . . . . . . . . . the desired expression for g(x)
3x-4=-31
+4 +4
3x=27
X=9
Hope this helps
Answer:
C
Step-by-step explanation:
Finding the z-score:
z = (x - μ) / σ
z = (66 - 57) / 9
z = 1
Using a z-score table or calculator:
P(z < 1) = 0.8413
84.13% of 4000 is:
0.8413 (4000) = 3365.2
Rounding up to the nearest whole number, approximately 3366 students will score less than 66. Answer C.
