1-9 are all numbers that are less than 10, and 1 is included because the number can be greater than or equal to 1.
Hope this helped!
No, it should not give exactly the right amount because numbers will have to be rounded because US dollars only go to the hundredths place making the final number slightly different than the exact value would be.
Answer:
435,307
Step-by-step explanation:
Given that :
p = 0.18
Zcritical = 99%
Error (E) = 1.5% = 1.5/100 = 0.0015
Sample size (n) can be obtained using the relation :
n = (Zcrit / E)^2 * (p * q)
q = 1 - p ; q = 1 - 0.18 = 0.82
Zcrit at 99% equals 2.576
n = (2.576 / 0.0015)^2 * (0.18 * 0.82)
n = (1717.3333)^2 * (0.1476)
n = 2949233.66328889 * 0.1476
n = 435306.888701440164
n = 435,307 samples
Answer:
Area of shaded region = 422 cm²
Step-by-step explanation:
Area of rectangle = length × breadth
= 3cm × 10cm
= 30cm²
Area of circle = πr²
= 3.14 × 12²
= 3.14 × 12cm × 12cm
= 452.16 cm²
Area of shaded region = Area of circle - Area of rectangle
= (452.16 - 30) cm²
= 422 cm²
