Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)

Answer:
x = 6
Step-by-step explanation:
Based on the two secants intersecting theorem, thus:
(x + 4)*4 = (3 + 5)*5
x*4 + 4*4 = (8)*5
4x + 16 = 40
4x + 16 - 16 = 40 - 16 (subtraction property of equality)
4x = 24
4x/4 = 24/4 (Division property of equality)
x = 6
Answer:
Area of Large Circle = 380.13
Area of Small Circle = 254.47
Area of Sidewalk = 125.66
Step-by-step explanation:
The side walk is just subtracting the smaller number from the bigger one.
The area is just Pi*r^2
The answer is 5/42 multiply 1*5=5 and 6*7=42 the 5 is the numerator and the denominator is 42 so you get 5/42.
