5 years?
A. 0.139%
B. 0.231%
C. 13.863%
D. 23.105%
Answers
Answer:
14.9%
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
A is the amount = $2000
P is the principal = $1000
r is the rate
T is the time = 5 years
Substitute the given values into the formula;
2000 = 1000(1+r)^5
2000/1000 = (1+r)^5
2 = (1+r)^5
[tex]\sqrt[5]{2} \\[/tex] = 1 + r
r = 1.149 - 1
r = 0.149%
Hence the required rate is 14.9%

Mr.Travelswell is about to visit Germany and Sweden. He has £5000 to spend. He wants to exchange 60% of this into Euros in Germany, and the rest into Krona in Sweden. When he changes his £5000, 1 Euro = £0.75 and £1=12.63 Krona. Calculate how many Euros and how many Krona he will receive.
Answers
answer:
4000 Euros and 25260 kronas.
detailed answer:
If £5000 is 100percent of his money, then 60percent is £X
x=(60×5000)/100= 3000(£)
rest of it is £2000
lets calculate Euros first:
3000/0.75=4000 (Euro €)
now kronas:
2000×12.63=25260 krona.

Answer:
f(15,055) is the number of pages in a book with 15,055 words.
Step-by-step explanation:
f(w) = length of book (in pages).
w = number of words
Thus, from the options given, the only true statement about the function is that:
f(15,055) = number of pages of a book that has 15,055 words.
"f(15,055)" is the length of a book consisting of 15,055 words. It does not imply that there are 15,055 pages.

to enter the upper limit for the interval where 68% of the values would fall
b. If the distribution of time spent on the job is approximately bell shaped, between what two times would 95% of the figures be?
enter the lower limit for the interval where 95% of the values would fall

Ah statistics
68-95-99.7
a. 68% is between -1 and 1 standard deviation, which is between 389 and 449 minutes
b. 95% is between -2 and 2 standard deviations, which is between 359 and 479 minutes
c. 99.7% is between -3 and 3 standard deviations, which is between 329 and 509 minutes
d. Use table A with a z-score of (360-419)/30 = -1.96666667
and with a z-score of (478-419)/30 = 1.96666667
NOTE THESE ARE NOT THE ANSWERS, but use the z-scores to find the percentage on table A
e. (400-419)/30 = -0.633333333 as his z-score
now find that value on table A
We are given the mean and the standard deviation. If the distribution is normal(bell-shaped), the Empirical Rule is used, otherwise, if the distribution is unknown, Chebyshev's Theorem is used.
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].
In this question:
Mean of 419, standard deviation of 30.
Question a:
Within 1 standard deviation of the mean, so:
419 - 30 = 389.
419 + 30 = 449.
Between 389 and 449 minutes.
Question b:
Within 2 standard deviations of the mean, so:
419 - 60 = 359
419 + 60 = 479
Between 359 and 479 minutes.
Question c:
Within 3 standard deviations of the mean, so:
419 - 90 = 329
419 + 90 = 509
Between 329 and 509 minutes.
Question d:
Have to find how many standard deviations it is from the mean:
(478 - 419)/30 = 1.97
(360 - 419)/30 = -1.97
Considering [tex]k = 1.97[/tex]
[tex]100(1 - \frac{1}{1.97^{2}}) = 74.2[/tex]
At least 74.2% of the times would be between 360 and 478 minutes.
Question e:
The z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
In which X is the measure, [tex]\mu[/tex] is the mean and [tex]\sigma[/tex] is the standard deviation.
For this question, X = 400, [tex]\mu = 419, \sigma = 30[/tex]
So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{400 - 419}{30}[/tex]
[tex]Z = -0.633[/tex]
This worker is in the lower half of workers but within 0.633 standard deviations of the mean.

[tex] \large{ \text{Hii,Hope \: you \: are \: fine!}}[/tex]
This is a question from coordinate geometry. This is a very simple question. You can solve it by using distance formula.
First we have to assume the coordinates as following:-
Let the coordinates of A be (8,4) and coordinates of B be (5,1).
Further we have to assume:-
[tex] \mapsto\sf{X_1=8}[/tex]
[tex]\mapsto \sf{Y_1=4}[/tex]
[tex]\mapsto \sf{X_2=5}[/tex]
[tex]\mapsto \sf{Y_2=1}[/tex]
Here we have distance formula:-
[tex] \sf{Distance \: of \: AB= \sqrt{({X_2-X_1) }^{2} + {( Y_2-Y_1) }^{2} } }[/tex]
[tex] \sf{Distance \: of \: AB= \sqrt{({5 - 8) }^{2} + {( 4 - 1) }^{2} } }[/tex]
[tex] \sf{Distance \: of \: AB= \sqrt{({ - 3) }^{2} + {( 3) }^{2} } }[/tex]
[tex] \sf{Distance \: of \: AB= \sqrt{9+ 9 } }[/tex]
[tex] \sf{Distance \: of \: AB= \sqrt{18} }[/tex]
[tex] \sf{Distance \: of \: AB= 3 \sqrt{2} cm }[/tex]

Answers
Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are: 7, 14, 21, 28, 35. You can get these by multiplying 7 to any integer.
7x1 = 77x2 = 147x3 = 217x4 = 287x5 = 35In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21

On a quiet day without many witnesses, a 4.5 ft victim was shot by a sniper that was in a tower 780 ft away. If the angle of elevation is 5 degrees from the victim, at what vertical distance did the sniper shoot from
Answers
Answer:
68.17m
Step-by-step explanation:
Please see attached a rough sketch of the scenario
Step one:
Given data
Height of victim= 4.5ft
The horizontal distance of the snipper from the building = 780ft
The angle of elevation= 5 degrees
Required
The vertical distance
The opposite= the vertical distance
789 ft = the adjacent
Step two:
Applying SOH CAH TOA
tan ∅= opp/adj
tan 5= opp/780
cross multiply we have
0.0874= opp/780
cross multiply we have
0.0874*780= opp
opp= 68.17m
The sniper shoots from a vertical distance of 68.17m
