Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-
As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence :
Then,
Hence, the minimum sample size required = 554.
because -2/5 is closer to 0 than -5/12
THEOREM:
- Angle sum property —: The sum of interior angles of a triangle is 180°.
ANSWER:
<u>By angle sum property</u>,
∠U + ∠V + ∠W = 180°
- 3x - 9° + 30° + 24° = 180°
- 3x + 45° = 180°
- 3x = 180° – 45°
- 3x = 135°
- x = 135/3
- x = 45°
So, <u>Correct choice</u> - [C] 45°.
Answer:
S = √(3V/H)
Step-by-step explanation:
The opposite operation of squaring is <em>taking the square root</em>.
_____
In the more general sense, the inverse operation for raising to a power is raising to the reciprocal of that power. We know that ...
(a^b)^c = a^(bc)
When we want bc=1, we must have c=1/b.
We know that the denominator of a fractional power is the index of the corresponding root:
For n=2, we don't usually write the index in the root symbol:
In the case of this problem, ...
