Tenzing sold two watches at rs1200 andrs1350 respectively if he gained 20 percent on the first and 2percent on the whole what percent did he loss in second watch
Answers
9514 1404 393
Answer:
10% loss
Step-by-step explanation:
If Tenzing sold the first watch at 20% profit, his cost c can be found from ...
1200 = 1.20c
1000 = c
If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...
2550 = 1.02t
t = 2550/1.02 = 2500
Then his cost for the second watch was ...
2500 -1000 = 1500
The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...
1500m = 1350
m = 1350/1500 = 0.90 = 1 - 0.10
Tenzing lost 10% of its cost on the second watch.

Based on a $400 loan amount, rank the following companies from the lowest to highest annual percentage rate (APR)
Answers
Answer:
Step-by-step explanation:
A = 40* (365/5)= 29.2%
B = 50*(365/12) = 15.2%
C= 80*(365/15)=19.46%
D = 100*(365/20)=18.25%
so best is B, then D , then C then A .
B,D,C,A in lowest to highest APR
As per the given data, with a base of $400 for loan amount, the ranking of all the given companies from the lowest to highest annual percentage rate is B,D,C, and A.
What is the annual percentage rate?Annual borrowing costs, including fees, are stated as a percentage and are known as the annual percentage rate, or APR. The APR is a more comprehensive indicator of how much borrowing money will cost because it includes both interest rates and application fees.
Instead of just a monthly fee or rate, the term annual percentage rate of charge refers to the interest rate for the entire year as applied to a loan, home loan, credit card, and many more. It can also be referred to as a nominal APR or an effective APR. It is a financial fee that is calculated at an annual rate.
Required calculations are as follow:
A = 40 × (365/5)= 29.2%
B = 50 × (365/12) = 15.2%
C= 80 × (365/15)=19.46%
D = 100 × (365/20)=18.25%
Therefore, the ranking of all the companies with the lowest to highest annual percentage rate are B,D,C, and A.

what are the outliers for 0,5,6,7,8,13
Answers
Given:
The date set is:
0,5,6,7,8,13
To find:
The outliers for the given data set.
Solution:
We have,
0,5,6,7,8,13
Divide the data in two equal parts.
(0,5,6),(7,8,13)
Divide each parenthesis in two equal parts.
(0),5,(6),(7),8,(13)
Here, first quartile is [tex]Q_1=5[/tex] and the third quartile is [tex]Q_3=8[/tex].
The interquartile range (IQR) is:
[tex]IQR=Q_3-Q_1[/tex]
[tex]IQR=8-5[/tex]
[tex]IQR=3[/tex]
The data lie outside the range [tex][Q_1-1.5IQR,Q_3+1.5IQR][/tex] is called outliers.
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-1.5(3),8+1.5(3)][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[5-4.5,8+4.5][/tex]
[tex][Q_1-1.5IQR,Q_3+1.5IQR]=[0.5,12.5][/tex]
The data values 0 and 13 lie outside the range [0.5,12.5].
Therefore, 0 and 13 are outliers of the given data set.
There are seven quarters in the bottom of a tote bag. Three of those quarters were minted in 2019, two were minted in 2001, and two were minted in 2008. What is the probability of selecting two quarters that were both minted in years other than 2019 if the first was not replaced before the second was selected?
Answers
Answer:
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]
Step-by-step explanation:
Given
[tex]n(2019)= 3[/tex]
[tex]n(2001)= 2\\[/tex]
[tex]n(2008)= 2[/tex]
[tex]n = 7[/tex] --- total
Required
[tex]P(Not\ 2019)[/tex]
When two quarters not minted in 2019 are selected, the sample space is:
[tex]S = \{(2001,2001),(2001,2008),(2008,2001),(2008,2008)\}[/tex]
So, the probability is:
[tex]P(Not\ 2019) = P(2001,2001)\ or\ P(2001,2008)\ or\ P(2008,2001)\ or\ P(2008,2008)[/tex]
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(2001,2001) = P(2001) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2001) = \frac{n(2001)}{n} * \frac{n(2001)-1}{n - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2001,2001) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2001,2001) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2001) = \frac{1}{21}[/tex]
[tex]P(2001,2008) = P(2001) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2001,2008) = \frac{n(2001)}{n} * \frac{n(2008)}{n - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2001,2008) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2001,2008) = \frac{2}{21}[/tex]
[tex]P(2008,2001) = P(2008) * P(2001)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2001) = \frac{n(2008)}{n} * \frac{n(2001)}{n - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{7 - 1}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{2}{6}[/tex]
[tex]P(2008,2001) = \frac{2}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2001) = \frac{2}{21}[/tex]
[tex]P(2008,2008) = P(2008) * P(2008)[/tex]
Since it is a selection without replacement, we have:
[tex]P(2008,2008) = \frac{n(2008)}{n} * \frac{n(2008)-1}{n - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{2-1}{7 - 1}[/tex]
[tex]P(2008,2008) = \frac{2}{7} * \frac{1}{6}[/tex]
[tex]P(2008,2008) = \frac{1}{7} * \frac{1}{3}[/tex]
[tex]P(2008,2008) = \frac{1}{21}[/tex]
So:
[tex]P(Not\ 2019) = P(2001,2001) + P(2001,2008) + P(2008,2001) + P(2008,2008)[/tex]
[tex]P(Not\ 2019) = \frac{1}{21} + \frac{2}{21} +\frac{2}{21} +\frac{1}{21}[/tex]
Take LCM
[tex]P(Not\ 2019) = \frac{1+2+2+1}{21}[/tex]
[tex]P(Not\ 2019) = \frac{6}{21}[/tex]
Simplify
[tex]P(Not\ 2019) = \frac{2}{7}[/tex]
The price of a cake of radius r сm and height h cm is given by the formula

of the cake.
pls provide step-by-step explanation, final ans is 20 cm. tysm <33
Answers
Answer:
20 cm
Step-by-step explanation:
Given that :
P = 1/25 r²h
P = price = 240 ; h = height = 15cm
Inputting values into the equation :
240 = 1/25 * r² * 15
25 * 240 = 15r²
6000 = 15r²
6000 / 15 = r²
400 = r²
Square root of both sides
20 = r
Radius = 20cm

The mean of six numbers is 10. When
mother number is added the new mean is
9. Find the number added.
Answers
Answer:
3
Step-by-step explanation:
If 6 numbers have a mean value of 10, it means that the sum of the numbers divided 6 is equal to 10. This can be expressed as:
x÷6=10
x=60
The new number added will be the 7th number and now the mean is 9. You have to ask what number divided by 7 is equal to 9? This can be expressed as:
y÷7=9
y=63
63-60=3
So the new number added is 3
Answer:
3
Step-by-step explanation:
Mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Given the mean of 6 numbers is 10, then
[tex]\frac{sum}{6}[/tex] = 10 ( multiply both sides by 6 )
sum = 60
When another number x is added then count is 7
[tex]\frac{60+x}{7}[/tex] = 9 ( multiply both sides by 7 )
60 + x = 63 ( subtract 60 from both sides )
x = 3 ← the number added

Explanation: you are trying to find the surface area. The formula for surface area is: Surface Area=2(width x length)+2(length x height)+2(height x width)
Since the question gives us the values of height, length and width. Just fill the information into the formula.
Surface Area=2(7x10)+2(10x3)+2(3x7)
Solve the parentheses:
Surface Area= 2(70)x2(30)+2(21)
Distribute the 2 into the parentheses:
Surface Area=140+60+42
