How many whole months will it take for a motorbike valued at £2550 to depreciate to less than £1200 if depreciation is at a rate of 5% per month?
It will take roughly 15.7 months to drop in value to less than £1200 if the current value of the bike is £2550.
How to find the present value of bike?You can use the following formula to calculate how many months it will take for a motorbike with a value of £2550 value to drop to under £1200:
n = (1200 - 2550) ln / ln (1 - 0.05)
Where 0.05 denotes the 5% monthly depreciation rate, ln is indeed the natural logarithm function, and n refers to the number of months.
When we enter the values, we will get:
n = (1200 - 2550 - 1 - 0.05) / ln(1 - 0.05) = about 15.7 months
The motorcycle will take approximately 15.7 months to drop in value to less than £1200.

Therefore , the solution of the given problem of percentage comes out to be time n = 3 years.
What is percentage?A figure or ratio that is stated as a percentage of 100 is referred to as a percentage in mathematics. However, the percent symbol ("%) is usually used to denote it." The percent amount is flat. When the numerator is 100, percentages are really just fractions. Put the standard form (%) next to a number to show that it is a percentage. For instance, if you correctly respond to 75 out of questions in total on a test, you receive a 75% (75/100).
Here,
Given: 1757600 more people overall
Population as of now: 1562500
According to the issue,
=> 1562500[tex](1 + 4/100 )^{n}[/tex] = 1757600
=> [tex](26/25)^{n}[/tex] = 1757600/ 1562500
=> [tex](26/25)^{n}[/tex]= [tex](26/25)^{3}[/tex]
On comparing,
n=3
Therefore , the solution of the given problem of percentage comes out to be time n = 3 years.

Translate the sentence into an equation.
Five times the sum of a number and 9 equals 3.
Use the variable y for the unknown number.
Answer: To translate the given sentence into an equation, we can start by replacing the words "five times the sum" with the mathematical expression "5(x + 9)". Then, we can replace the word "number" with the variable y, to get:
5(y + 9) = 3
Next, we can distribute the 5 to obtain:
5y + 45 = 3
Finally, we can subtract 45 from both sides to solve for y:
5y = -42
y = -42/5
y = -8.4
Therefore, the equation that represents the given sentence is y = -8.4.

Mr. Hughes gave 5/14
of his savings to his son, 2/3 of the remainder to his daughter, and the rest to his wife.
If his wife got $900, what were his savings?
Answer:
His savings were of $4,200.
Step-by-step explanation:
Mr. Hughes gave 5/14 of his savings to his son, 2/3 of the remainder to his daughter, and the rest to his wife:
This means that the son and daughter amount is:
[tex]\frac{5}{14} + \frac{2}{3}(\frac{9}{14})[/tex]
As [tex]\frac{9}{14}[/tex] is the remained that his son did not get. So
[tex]\frac{5}{14} + \frac{2}{3}(\frac{9}{14}) = \frac{15}{42} + \frac{18}{42} = \frac{33}{42}[/tex]
Fraction his wife got:
[tex]1 - \frac{33}{42} = \frac{42}{42} - \frac{33}{42} = \frac{9}{42}[/tex]
If his wife got $900, what were his savings?
Total savings are x, wife got [tex]\frac{9}{42}[/tex] of x. So
[tex]\frac{9x}{42} = 900[/tex]
[tex]9x = 900*42[/tex]
[tex]x = \frac{900*42}{9}[/tex]
[tex]x = 100*42[/tex]
[tex]x = 4200[/tex]
His savings were of $4,200.

The possibility that Jacinta will choose the green marble is 45.5%
What is probability?Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.
Given that, Jacinta has 2 blue marbles, 4 red marbles and 5 green marbles in a bag, all the marbles are the same size,
We need to find the possibility that Jacinta will choose the green marble,
So, here we will use the concept of probability, probability tell us the chances of happening of an event.
The formula =
Probability = favorable outcomes / total outcomes.
Here, the favorable outcomes = green marble (5)
The total outcomes = total number of marbles = 5+4+2 = 11
So, P(getting the green marble) = 5/11 = 0.454545 = 45.5%
Hence, the possibility that Jacinta will choose the green marble is 45.5%

An average human heart beats 60 times per minute. If an average person lives to the age of 75, how many times does the average heartbeat in a lifetime?
There should be ( ) heartbeats per lifetime.
(Enter your answer as a decimal number. Round to two decimal places.)
Answer:
The average number of beats in a lifetime would be 2,365,200,000
Step-by-step explanation:
To find the amount we need to take basic steps. The first step is multiplying the number of beats to find out how many are in an hour. Since there are 60 in a minute and 60 minutes in an hour, multiply the two.
60 beats * 60 minutes = 3,600 beats per hour.
Now multiply the amount of beats in an hour by the number of hours in a day.
3,600 * 24 hours = 86,400 beats per day
Now multiply the number of days in a year. Technically there is 365 1/4 in a year, but we'll use the flat rate of 365 since that is generally the accepted answer.
86,400 * 365 days = 31,536,000 beats per year
And now we take that number and multiply by the number of years that he lines
31,536,000 * 75 years = 2,365,200,00 beats in a lifetime
The heart beats 236,520, 000 times in a lifetime.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
An average human heart beats 60 times per minute.
Now, the amount of beats in an hour by the number of hours in a day.
= 3,600 x 24 hours
= 86,400 beats per day
Again, the amount of beats per year
= 86,400 x 365 days
= 31,536,000 beats per year
So, the heart beats
= 31,536,000 x 75 years
= 236,520, 000 beats in a lifetime

b) What is the probability that the sample mean score of 64 randomly selected student is 80 or higher?
c) What is the probability the sample mean score of 64 randomly selected students is between 74 and 76?
Answer:
The appropriate solution is:
(a) 0.1056
(b) 0
(c) 0.9544
Step-by-step explanation:
The given values are:
Mean,
[tex]\mu = 75[/tex]
Standard deviation,
[tex]\sigma = 4[/tex]
(a)
⇒ [tex]P(x>80)=1-(x<80)[/tex]
[tex]=1-P[\frac{x-\mu}{\sigma} <\frac{80-75}{4} ][/tex]
[tex]=1-P[\frac{x-\mu}{\sigma} <\frac{5}{4} ][/tex]
[tex]=1-P(z<1.25)[/tex]
By using the table, we get
[tex]=1-0.8944[/tex]
[tex]=0.1056[/tex]
(b)
According to the question, the values are:
[tex]n[/tex] = 64
[tex]\mu_\bar{x}[/tex] = 75
Now,
⇒ [tex]\sigma_\bar{x}[/tex] = [tex]\frac{\sigma}{\sqrt{n} }[/tex]
= [tex]\frac{4}{\sqrt{64} }[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]0.5[/tex]
⇒ [tex]P(\bar {x} >80 ) = 1 - P(\bar x <80 )[/tex]
[tex]=1 - P[\frac{(\bar x-\mu_\bar x)}{\sigma \bar x} < \frac{80-75}{0.5} ][/tex]
[tex]=1-P(z<10)[/tex]
By using the table, we get
[tex]=1-1[/tex]
[tex]=0[/tex]
(c)
As we know,
⇒ [tex]\sigma_\bar x[/tex] = [tex]\frac{\sigma}{\sqrt{n} }[/tex]
= [tex]\frac{4}{\sqrt{64} }[/tex]
= [tex]\frac{4}{8}[/tex]
= [tex]0.5[/tex]
then,
= [tex]P(74< \bar x <76)[/tex]
= [tex]P[\frac{74-75}{0.5} < \frac{\bar x-\mu \bar x}{\sigma \bar x} < \frac{76-75}{0.5} ][/tex]
= [tex]P(-2<z<2)[/tex]
= [tex]P(z<2)-P(z<-2)[/tex]
By using the table, we get
