I NEED TO REPLACE MY CONCRETE IN 7 YEARS. THE TOTAL COST IS $15,000, HOW MUCH DO I NEED TO SAVE ANNUALLY AT 5%.
Answers
9514 1404 393
Answer:
$1,754.57
Step-by-step explanation:
If you put the amount in savings at the beginning of the year, then the balance after 7 years is ...
A = P(1 +r)((1 +r)^7 -1)/r . . . . for payment P at annual rate r for 7 years
15000 = P(1.05)(1.05^7 -1)/0.05 = 8.54911P
Then the amount P that needs to be saved is ...
15000/8.54911 = P = 1754.57
You need to deposit $1,754.57 at the beginning of each year for 7 years to have a balance of $15,000 at the end of 7 years.
_____
If you wait until the end of the year to deposit the money, the amount will need to be 5% higher: $1,842.30.

what is the answer to -1.4b+10=-18
Answers
Answer:
Step-by-step explanation:
by answer i'm guessing that you mean, solve for "b" correct? or another way to say this, is that we want to isolate b. get by itself on one side of the equation, either side is fine, it's not important which side, but it just needs to be alone. :)
-1.4b + 10 = -18
since you're asking about algebra , i'll go slow explaining, but just tell me if I sound like i'm "mansplaining" :0
first , recall to do algebra we need to know the order of operations or P.E.M.D.A.S or Parenthesis, Exponents, , Multiplication, Division, Addition, Subtraction. so, keep in mind, that we want to use these list of "Order of operations" in reverse, that is we start at the bottom and work up on the list. I think math teacher always kinda "gloss" over this point. :/ anyway, looking for any Subtracting... hmm
subtract 10 from both sides
-1.4b + 10 - 10 = -18 - 10
-1.4b = -28
now lets move up the order of operations to "Multipication and Division"
divide both sides by -1.4
-1.4b / -1/4 = -28 /-1.4
b = 20
note that the double negative , on both sides cancel out
and , also, I used my calculator to divide 28 by 1.4 to get 20 :P

suppose a continous random variable x can take on values over the set [0,a] and has a probability denisity function cx^n, x = E (0,a), where a= 3, n=2 , find C!
Answers
The value of C is 1/9 for the probability density function using integration.
We know that the probability density function (pdf) integrates to 1 over the interval [0, a]:
∫[0,a] cx^n dx = 1
Substituting the given values for n and a, we get:
∫[0,3] cx^2 dx = 1
Integrating with respect to x:
c ∫[0,3] x^2 dx = 1
c [x^3/3] from 0 to 3 = 1
c (3^3/3 - 0) = 1
c = 1/9

if we want to provide a 99onfidence interval for the mean of a population, what will the confidence coefficient be?
Answers
If we want to provide a 99% confidence interval for the mean of a population, the confidence coefficient will be 0.99. This means that there is a 99% probability that the true population mean falls within the calculated interval.
The confidence coefficient for a confidence interval represents the level of confidence we have in our estimate.
In the case of a 99% confidence interval, the confidence coefficient is 0.99. This means that we are 99% confident that the true population mean falls within the calculated interval. The confidence coefficient is derived from the desired level of confidence, which is typically expressed as a percentage.
A higher confidence level corresponds to a larger confidence coefficient. In practical terms, a 99% confidence interval indicates that if we were to repeat the sampling process multiple times and construct 99% confidence intervals, approximately 99% of those intervals would contain the true population mean.

a) Simplify them and find You bought 3 gel pens at Rs 25 each, 6 pencils at Rs 10 each and 2 boxes at Rs 80 each. If you gave a Rs 500 note to the shopkeeper, what changes did the shopkeeper return you? 1)
Answers
After calculating the total cost, it can be obtained that the shopkeeper returned Rs \(205\) in changes.
How to find the total cost of all the products bought?The total cost will be the sum of the costs of each product.
Here, given that \(3\) gel pens are bought at Rs \(25\) each. So, the cost of these \(3\) gel pens is \(25\times 3=\text{Rs}\hspace{1mm}75\).
Also, \(6\) pencils are bought at Rs \(10\) each. So, the cost of these \(6\) pencils is \(10\times 6=\text{Rs}\hspace{1mm}60\).
Also, given that \(2\) boxes are bought at Rs \(80\) each. So, the cost of these \(2\) boxes is \(80\times 2=\text{Rs}\hspace{1mm}160\).
Thus, the total cost of all the products bought is \(75+60+160=\text{Rs}\hspace{1mm}295\).
So, if Rs \(500\) were given to the shopkeeper, then he should have return \(500-295=\text{Rs}\hspace{1mm}205\) in changes.
Therefore, after calculating the total cost, we have obtained that the shopkeeper returned Rs \(205\) in changes.

In a large introductory statistics lecture hall, the professor reports that 51% of the students enrolled have never taken a calculus course, 30% have taken only one semester of calculus, and the rest have taken two or more semesters of calculus. The professor randomly assigns students to groups of three to work on a project for the course. You are assigned to be part of a group.
a) What is the probability that of your other two groupmates, neither has studied calculus? (type an integer or decimal)
b) What is the probablity that both of your other two groupmateshave studied at least one semester of calculus? (type an integer or decimal)
c) What is the probablity that at least one of your two groupmates has had more than one semester of calculus? (type an integer or decimal)
Answers
The probability that at least one of your two groupmates has had more than one semester of calculus is approximately 0.9639.
1a) The probability of a randomly played song being a rap song can be calculated by dividing the number of rap songs by the total number of songs in the list:
Probability = Number of rap songs / Total number of songs
Probability = 5 / (7 + 5 + 8) = 5 / 20 = 0.25
Therefore, the probability of a randomly played song being a rap song is 0.25.
1b) The probability of a randomly played song not being country can be calculated by subtracting the number of country songs from the total number of songs in the list and dividing it by the total number of songs:
Probability = (Total number of songs - Number of country songs) / Total number of songs
Probability = (7 + 5) / (7 + 5 + 8) = 12 / 20 = 0.6
Therefore, the probability of a randomly played song not being country is 0.6.
2a) To calculate the probability that neither of your two groupmates has studied calculus, we need to find the probability of both groupmates not having studied calculus.
Probability = (Probability of first groupmate not studying calculus) * (Probability of second groupmate not studying calculus)
Since 51% of students have never taken calculus, the probability of one groupmate not having studied calculus is 0.51. Assuming independence, the probability of the second groupmate not having studied calculus is also 0.51.
Probability = 0.51 * 0.51 = 0.2601
Therefore, the probability that neither of your two groupmates has studied calculus is approximately 0.2601.
2b) To calculate the probability that both of your other two groupmates have studied at least one semester of calculus, we need to find the probability of both groupmates having studied calculus.
Probability = (Probability of first groupmate studying calculus) * (Probability of second groupmate studying calculus)
The probability of one groupmate having studied calculus is 1 - 0.51 = 0.49. Assuming independence, the probability of the second groupmate having studied calculus is also 0.49.
Probability = 0.49 * 0.49 = 0.2401
Therefore, the probability that both of your other two groupmates have studied at least one semester of calculus is approximately 0.2401.
2c) To calculate the probability that at least one of your two groupmates has had more than one semester of calculus, we can find the complementary probability of both groupmates not having more than one semester of calculus.
Probability = 1 - (Probability of both groupmates not having more than one semester of calculus)
The probability of one groupmate not having more than one semester of calculus is 1 - (0.51 + 0.30) = 0.19. Assuming independence, the probability of the second groupmate not having more than one semester of calculus is also 0.19.
Probability = 1 - (0.19 * 0.19) = 1 - 0.0361 = 0.9639
Therefore, the probability that at least one of your two groupmates has had more than one semester of calculus is approximately 0.9639.

Answers
Therefore, 6 minutes and 40 seconds are needed to test possibilities.
Describe combination.Combinations are sometimes known as selections. Combinations are the results of selecting elements from a set assortment. Nothing specific is being organized here. We are choosing them. To denote the number of unique r-selections or combinations among a set of n items, we write n C r. Combinations are distinct from arrangements or permutations.
Here,
The first two numbers in this three-term series are 17 and 24, and the third one remains a mystery.
Given that there are 40 options for the third number and that each try takes 10 seconds, we have 40 x 10 seconds, or 400 seconds, to try every possible combination.
Thus,
=> 400 seconds is equals to 6 minutes and 40 seconds
Therefore, 6 minutes and 40 seconds are needed to test every scenario.
