1 1/6 hours is equal to 60 minutes add 10 minutes = 70 minutes
7/8 takes 70 minutes
To find out what can be done in 10 minutes, divide both numbers by 7
7/8 / 7 = 1/8
1/8 takes 10 minutes
To find out how much is painted in 1 minute, divide both by 10
1/8 / 10 = 1/80
1/80 takes 1 minute
Answer:
30%
Step-by-step explanation:
Total population=15,000
kantipur=9000
gorkhapatra= 7500
Both magazine=40%
n(k intersection g)=40% of 15,000
=0.4*15,000
=6,000
n(k) =9000
n(g)=7500
n(A union B)= n(k) + n(g) -n(k intersection g)
=9000+7500-6000
=10,500
Population who do no read= Total population - n(A union B)
=15000-10500
=4500
Percentage population who do not read both magazine
=4,500/15,000 * 100
=0.3 * 100
=30%
Answer:
Step-by-step explanation:
a) Sample statistics are used to estimate population value. Since 48% is a sample proportion, therefore, it is a sample statistic.
b) For 95% confidence level, z* = 1.96.
\hat{p}\pm z^* \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}= 0.61\pm 0.61\sqrt{\frac{0.61(1-0.61)}{1578}}=0.61\pm 0.024 \ or (0.586, 0.634).
We are 95% confident that the true proportion of US residents who think marijuana should be made legal lies between 58.6% and 63.4%.
c)
\\np=1578(0.61)=962.58
\\n(1-p)=1578(1-0.61)=615.42
Since both np and n(1-p), are at least 10, the normal model is a good approximation for these data.
d) As the lower limit of confidence interval is less than 0.5, less than 50% population is also a plausible value of true proportion. This means the statement "Majority of Americans think marijuana should be legalized" is not justified.
The answer is D) 16
The reason why is because 16 = 2*2*2*2 has only 2 as its prime factor. Any time 2 or 5 are the prime factors of the denominator, then the decimal will terminate. Examples include fractions like 1/2, 1/5, 1/10
1) You have four tiles that say M, A, T, and H. How many words can you form from these tiles? For example, you can form "AMH" and "TH". (The words do not have to be valid English words.)
2)How many numbers among 1, 2, 3, 1000 are not divisible by 9?
3)Andrew chooses a number from 1 to 100, and Mary also chooses a number from 1 to 100. (They may choose the same number.) It turns out that the product of their numbers is even. In how many ways could Andrew and Mary have chosen their numbers?
4)How many numbers between 50 and 250 (inclusive) are not perfect squares?
5)Dmitri has a pair of standard dice; one die is blue, and the other die is yellow. He rolls both of his dice. How many ways could the number on the blue die be larger than the number on the yellow die?
6) Bob flips a penny, a nickel, and a dime. How many ways can she get at least two heads?
