A radio station gives away $15 to every 15th caller, $25 to every 25th caller, and free concert tickets to every 100th caller. When will the station first give away all three prizes to one caller? PLEASE HELP. Show your work !!
We want to find the lowest common multiple of 3 numbers.
We will see that the 300th caller will get the 3 prizes.
Ok, we know that:
each 15th caller gets $15.each 25th caller gets $25.each 100th caller gets free concert tickets.We want to see the first time that the 3 prizes will be given at the same time (at the same caller).
This will happen for the lowest common multiple of 15, 25 and 100
Now, to find the lowest common multiple we can use brute force, this is, writing all the multiples of the 3 numbers and watching which one is the first to appear in the 3 lists, but here we can do another thing.
One of the numbers is 100, so its multiples are:
100, 200, 300.
And we know that with 25 we can make all of these numbers:
25*4 = 100
25*8 = 200
25*12 = 300
So all the multiples of 100 are also multiples of 25.
Then we just need to find the first common multiple between 100 and 15.
To get this, we can decompose both numbers as a product of primes:
15 = 3*5
100 = 10*10 = 2*5*2*5
Now we multiply these, but if there is some factor that appears in both numbers we remove it (only from one).
For example, here we can see that the factor 5 appears in both numbers, so we need to remove one of the fives in the product.
We will get:
(3*5)*(2*5*2) = 300
So the lowest common multiple is 300.
This means that the 300th caller will get the 3 prizes.

The graph shows the number of each kind of book in Hero's personal library. A book is chosen randomly. What is the probability that the book chosen is a biography?
A)2/15
B)4/15
C)1/30
D)1/4
Answer: A is the right answer .Probability of the book chosen is a biography is [tex]\frac{2}{15}[/tex].
Step-by-step explanation:
According to the given graph or pie chart
The number of biography books=4
Total books= Romance books+ Science fiction books+ Biography books+Adventure books =2+14+4+10=30
Let B be the event of choosing a biography book then
Probability of the book chosen is a biography P(B)=[tex]=\frac{biography\ books}{total\ books}=\frac{4}{30}=\frac{2}{15}[/tex]
Therefore, Probability of the book chosen is a biography is [tex]\frac{2}{15}[/tex].
From the graph, it is found that there is a [tex]\mathbf{\frac{2}{15}}[/tex] probability that the book chosen is a biography, and the correct option is given by option A.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There are 4 + 2 + 10 + 14 = 30 books in the hero's library.Of those, 4 are biographies.[tex]p = \frac{4}{30} = \frac{2}{15}[/tex]

Problem: Find the value of $x$ that maximizes $$f(x) = \log (-20x + 12\sqrt{x}).$$ If there is no maximum value, write "NONE".
Answer:
The value of x is 0.09
Step-by-step explanation:
Here, the given function is,
[tex]f(x)=\log(-20x+12\sqrt{x})[/tex]
Differentiating with respect to x,
[tex]f'(x)=\frac{1}{-20x+12\sqrt{x}}(-20+\frac{12}{2\sqrt{x}})[/tex]
[tex]=\frac{-20+\frac{6}{\sqrt{x}}}{-20x+12\sqrt{x}}[/tex]
[tex]=\frac{-10+\frac{3}{\sqrt{x}}}{-10x+6\sqrt{x}}[/tex]
[tex]=\frac{-10\sqrt{x}+3}{2\sqrt{x}(-5x+3\sqrt{x})}[/tex]
Again differentiating with respect to x,
[tex]f''(x)=-\frac{(-10\sqrt{3}+3)(-15x+3\sqrt{3})}{4x\sqrt{x}(-5x+3\sqrt{x})}[/tex]
For maxima or minima,
[tex]f'(x) = 0[/tex]
[tex]\implies \frac{-10\sqrt{3}+3}{2\sqrt{x}(-5x+3\sqrt{3})}=0[/tex]
[tex]\implies x \approx 0.09[/tex]
At x = 0.09,
f''(x) = negative,
Hence, for x = 0.09, f(x) is maximum.

A sofa is on sale for 357 which is 32 percent less than the original price how much is the original price
The sofa's original price is calculated by using the formula: original price = sale price/percentage in decimal format. In this case, the percentage is 68%, and hence the original price would be 357 / 0.68 which is equal to $525.
Explanation:This is a percentage problem. If the sale price of $357 represents 68% of the original price (because 100% - 32% is 68%), we can find the original price of the sofa using the formula: original price = sale price/percentage in decimal format.
Therefore, the original price would be 357 / 0.68 = $525

Felicia installed a new pool for $17,190 using a 12-month deferred payment plan with an interest rate of 18.67%. What is the balance after the deferment period if payments of $589 are made each month?
a. $10,122.00
b. $20,688.76
c. $13,620.76
d. $17,190.00
Answer:
a. $10,122.00
Step-by-step explanation:
By definition the deferment period is a time during which a borrower does not have to pay interest or repay the principal on a loan.
In this case the balance should be the initial value $17,190, but Felicia made 12 payments of $589 each one.
So, $589 x 12 = $ 7,068.
$17,190- $ 7,068 = $10,122

A researcher wants to know if the average time in jail for robbery has increased from what it was when the average sentence was 7 years. he obtains data on 400 more-recent robberies and finds an average time served of 7.5 years. find a 95% confidence interval for the average time served (assume jail time follows a normal distribution with standard deviation 3 years).
At 95% confidence interval, the z score is 1.96. Using the formula:
Confidence Interval = x ± z s / sqrt (n)
where x is the average time served, s is standard deviation and n is number of samples
Confidence interval = 7.5 ± (1.96 * 3) / sqrt (400)
Confidence interval = 7.5 ± 0.294
Confidence interval = 7.206 to 7.794

henry is following the recipe card to make a cake. he had 95 cups of flour. how many cakes can henry make?
flour needed for each cake
2 2/9 cups of batter
1/2 cup for topping
Answer:
the number of cakes that can be produced is only 34.
Step-by-step explanation:
total flour needed = flour need for batter + flour needed for topping
,
total flour needed = 2 2/9 cups + 1/2 cup = 49/18 cups
after, we divide the total amount of flour by the answer obtained above to determine the number of cakes that can be made.
number of cakes is the total amount of flour needed per cake
number of cakes is 95 cups / (49/18) = 34.89 cakes
the number of cakes that can be produced is only 34.
