Answer:
Therefore the correct option is D.) Yes, 10(3000) = 30,000 which is less than the population.
Step-by-step explanation:
i) Sample size = 3000
ii) the condition for a sample is that the sample size cannot be over 10% of population
iii) population size is = 8,000,000 (8 million)
iv) therefore 10% of 8,000,000 = 800000 which is more than 3,000
So the answer is Yes. the 10% condition is met.
Therefore the correct option is D.) Yes, 10(3000) = 30,000 which is less than the population.
Answer:
55°
Step-by-step explanation:
- By theorem of specific circle, the radius is perpendicular to the tangential line
- Summation of all internal angles equal to 180°
Thus from the atrachment, the angle PGR is 180°-35°-90°
= 55°
Answer:
9 hours
Step-by-step explanation:
1/18 in 1/2 an hour
2/18 or 1/9 in 1 hour
1/9 * 9 = 1
1 hour * 9 = 9
Estimate of the quotient:
3 3/7 = 3+0.428571=3.428571
1 4/9 = 1+0.444444=1.444444
(3 3/7) / (1 4/9) = 3.428571 / 1.444444 = 2.373627
Estimate of the quotient: 2.373627
Exact quotient:
3 3/7=(7*3+3)/7=(21+3)/7=24/7
1 4/9=(9*1+4)/9=(9+4)/9=13/9
(3 3/7) / (1 4/9) = (24/7) / (13/9) = (24/7)*(9/13)=(24*9) / (7*13)=216/91
Exact quotient: 216 / 91 = (182+34) / 91 = 182 / 91 + 34 / 91 = 2 34/91
Exact quotient: 216/91 = 2 34/91
Simplify 3/5p tp 3p/5
4 + 2p = 10(3p/5 - 2)
Expand
4 + 2p = 6p - 20
Subtract 2p from both sides
4 = 6p - 20 - 2p
Simplify 6p - 20 - 2p to 4p - 20
4 = 4p - 20
Add 20 to both sides
4 + 20 = 4p
Simplify 4 + 20 tp 24
24 = 4p
Divide both sides by 4
24/4 = p
Simplify 24/4 to 6
6 = p
Switch sides
<u>p = 6</u>
