IF a man converted Rs.150000 into pound sterling.
After one week Nepalese rupees devalued by 5% then find
the he has profit or loss. ( 1 pound sterling = Rs.77.02)
Answer:
The man has made a profit, for with the same money he bought more British Pounds than he could have bought a week later.
Step-by-step explanation:
Given that a man converted Rs. 150000 into pound sterling, and after one week Nepalese rupees devalued by 5%, to find if you have obtained a profit or a loss, the following calculation must be performed:
150,000 / 77.02 = X
1,947.55 = X
150,000 / (77.02 x 1.05) = X
150,000 / 80.87 = X
1,854.82 = X
Therefore, the man has made a profit, for with the same money he bought more British Pounds than he could have bought a week later.

There are 20 bears in a zoo. What will be their population after 3 years, if the population doubles each year?
Answer:
160
Step-by-step explanation:
20 x 2 = 40
40 x 2 = 80
80 x 2 = 160
It stops at 3 years.
Answer:
120
Step-by-step explanation:
20+40+60 = 120
If we double it, we have to keep adding 20 each year and stop at 3 so the answer is 120

Find the area of a circle with a radius of 21 inches.
Answer:
A≈1385.44in²
Step-by-step explanation:
A=πr2=π·212≈1385.44236in²
Answer:
1384.74 inches.
Step-by-step explanation:
The formula for area of a circle is:
[tex]a=\pi *r^2(3.14*radius*radius)[/tex]
[tex]\pi =3.14, r=radius.[/tex]
According to the word problem, the radius of the circle is 21 inches.
Now, we can just plug the numbers into the formula.
[tex]\pi *21^2(3.14*21*21)=1384.74[/tex]
Therefore, the area of the circle is 1384.74 inches.

Answer:
Because there are 9 sour straws in total and 3 blue sour straws, the probability of pulling out a blue sour straw would be 3/9 or 1/3. Because we aren't replacing it, that means that there's one less straw in the box so there should only be 8 straws left. Because there's 4 pink sour straws, the probability of pulling out a pink sour straw is 4/8 or 1/2.

Seventeen percent of U.S. residents are in their thirties. Consider a group of nine U.S. residents selected at random. Find the probability that three or four of the people in the group are in their thirties.
Answer:
0.1764
Step-by-step explanation:
This problem meets requirement that enables us to use the binomial probability relation :
Probability of success, p = 17% = 0.17
number of trials = 9
(1 - p) = 1 - 0.17 = 0.83
The binomial probability relation :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 3) = 9C3 * 0.17^3 * 0.83^6
P(x = 3) = 84 * 0.001606258054361897
P(x = 3) = 0.134925676566399348
P(x = 3) = 0.13492
P(x = 4) = 9C4 * 0.17^4 * 0.83^5
P(x = 4) = 126 * 0.000328992613544003
P(x = 4) = 0.041453069306544378
P(x = 4) = 0.04145
P(x = 3 or x = 4) = P(x = 3) + p(x = 4)
= 0.13492 + 0.04145
= 0.17637
= 0.1764
g The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 customers to check out was 3.0 minutes. It is known that the standard deviation of the checkout time is 1 minute. Refer to Exhibit 8-2. The 95% confidence interval for the average checkout time for all customers is _____. a. 2.804 to 3.196 b. 1.04 to 4.96 c. 1.36 to 4.64 d. 3 to 5
Answer:
The right solution is "0.196".
Step-by-step explanation:
The given values are:
Standard deviation,
[tex]\sigma=1 \ minute[/tex]
Sample size,
[tex]n=100[/tex]
Confidence level,
[tex]c=95[/tex]%
[tex]=0.95[/tex]
Now,
For [tex]\alpha=1-c[/tex]
[tex]= 1-0.95[/tex]
[tex]=0.05[/tex]
then,
[tex]Z_{\frac{\alpha}{2} } = Z_{\frac{0.05}{2} }[/tex]
[tex]=Z_{0.025}[/tex]
[tex]=1.96[/tex]
The margin or error will be:
⇒ [tex]E=Z_{\frac{\alpha}{2} } (\frac{\sigma}{\sqrt{n} })[/tex]
On substituting the values, we get
= [tex]1.96(\frac{1}{\sqrt{100} })[/tex]
= [tex]1.96\times \frac{1}{10}[/tex]
= [tex]0.196[/tex]

Is it possible to find two data sets A and B such that A has a greater median and mode, while B has a greater average and range? If you think the answer is yes, provide an example. If you think the answer is no, explain why not.
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The median is the middle value (or the average of the two middle values)
The average or mean is:
[tex]m = \frac{x_1 + ... + x_n}{N}[/tex]
The mode is the value that is more repeated.
The range is the difference between the largest value and the smallest value.
Now, let's try to construct two sets A and B that meet the required conditions:
Let's suppose two sets of 5 values each:
A = {2, 2, 3, 4, 5}
The median of A is 3.
The range of A is = 5 - 2 = 3
The average of A is: (2 + 2 +3 +4 +5)/5 = 16/5
And the value "2" appears two times, so the mode is 2.
Now, let's try to find a data set B such that:
The mode is smaller than 2 (so for example, we can have a "1" that repeats two times)
The median is smaller than 3 (let's have a median equal to 2)
The average is larger than 16/5
The range is larger than 3
This is ratter simple:
B = {1, 1, 2, 6, 9}
The median of B is 2.
The mode of B is 1
The range of B is: 9 - 1 = 8
The average of B is: (1 + 1 + 2 + 6 + 9)/5 = 19/5
So, we just found an example for two data sets A and B such that A has a greater median and mode, while B has a greater average and range.
So the answer is yes, it is possible.

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hours:
A graph titled Motion of a Dragonfly shows Time in hours on the x axis and Distance in miles on the y axis. The scale on the x axis shows number from 0 to 10 at increments of 2, and on the y axis, the numbers are shown from 0 to 220 at increments of 44. A straight line joins the ordered pairs 0, 0 and 2, 44 and 4, 88, and 6, 132
Based on the graph, what is the dependent variable, the equation relating the two variables, and how far will the dragonfly travel in 24 hours if it continues to fly at the same speed?
The dependent variable is time, the equation is y = 22x, and the dragonfly will travel 528 miles.
The dependent variable is time, the equation is x = 22y, and the dragonfly will travel 1,056 miles.
The dependent variable is distance, the equation is y = 22x, and the dragonfly will travel 528 miles.
The dependent variable is distance, the equation is x = 22y, and the dragonfly will travel 1,056 miles.
