If you can choose a prize of either a $25,000 car or one penny on the first day. The number of days you receive more than the value of the car is 15 days.
How to find the number of days?Let x represent the number of days
Convert $25,000 to cents by multiplying it by 100
$25,000 × 100 = 2,500,000 cents
Hence:
3^x-1 > 2,500,000
(x-1) log3/log 3 > log 2500000/log 3
x-1 > 13.409
x = 13.409+1
x =14.409
x = 15 days (Approximately)
Therefore the number of days is 15.

Eduardo decided to invest money in an account that earns 3% compounded semi-annually. If he initially
deposited $750 into the account, how much will it be worth in 8 years? Round answer to the nearest
hundredth.
Answer:
$951.74
Step-by-step explanation:
You want the future value of $750 earning 3% per year for 8 years, compounded semi-annually.
Compound interestThe value of an account earning interest at rate r on principal P compounded n times per year for t years is ...
A = P(1 +r/n)^(nt)
For P=750, r=0.03, n=2, t=8, this is ...
A = 750(1 +0.03/2)^(2·8) = 750(1.015^16) ≈ 951.74
The account will be worth about $951.74 in 8 years.

What is the solution to this system of linear equation 3x 2y 14?.
The solutions to this system of linear equation 3x−2y=14 is ( [tex]\frac{2y + 14}{3}[/tex] , [tex]\frac{3x}{2}[/tex]-7).
Add 2y to both sides.
3x=14+2y
The equation is in standard form.
3x=2y+14
Divide both sides by 3.
[tex]\frac{3x}{3}[/tex] = [tex]\frac{2y + 14}{3}[/tex]
Dividing by 3 undoes the multiplication by 3.
x = [tex]\frac{2y + 14}{3}[/tex]
Now,
3x−2y=14
Subtract 3x from both sides.
−2y=14−3x
Divide both sides by −2.
[tex]\frac{-2y}{-2}[/tex] = [tex]\frac{14 - 3x}{-2}[/tex]
Dividing by −2 undoes the multiplication by −2.
y = [tex]\frac{14 - 3x}{-2}[/tex]
Divide 14−3x by −2.
y = [tex]\frac{3x}{2}[/tex] - 7

a pharmaceutical company receives large shipments of ibuprofen tablets and uses an acceptance sampling plan. this plan randomly selects and tests 21 tablets, then accepts the whole batch if there is at most one that doesn't meet the required specifications. what is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects? (report answer as a decimal value accurate to four decimal places.) p(accept shipment)
0.9660 is the probability that this whole shipment will be accepted if a particular shipment of thousands of ibuprofen tablets actually has a 15% rate of defects
What is probability ?Probability turned into added into arithmetic to are expecting the possibility of an occasion occurring. Probability essentially approach how in all likelihood it's miles that some thing will happen. This is the fundamental principle of possibility and is likewise utilized in possibility distributions to examine feasible consequences of random experiments.
CalculationIf the number of tablets in a shipment is sufficiently large, we can consider the testing procedure you describe (selecting a random sample of 29 ibuprofen tablets and counting the number of defective tablets in the sample) to be a binomial probability experiment.
Let X = (Number of defective ibuprofen tablets in a random sample of 29 tablets.) Then we may reasonably assume that X follows a binomial distribution. For each "trial" (that is, each tablet selected), there are two possible outcomes, "success" (the tablet is defective), or "failure" (the tablet is not defective). Note that the word success as used in the binomial distribution does not carry the connotation of being a "good" outcome. A "success" is simply the outcome you are interested in counting, which in this case is the number of defectives in the sample. The important parameters for a binomial distribution are n (the number of trials) and p (the probability of success on any one trial.) For this situation, we have p = .01 (since we are told 1% of the tablets in the shipment are defective) and n = 29. The general formula for the binomial distribution is
P(x) = nCx·px·(1 - p)n-x
where x is the number of successes in n trials (In this problem, x is the number of defectives in a random sample of 29 tablets.) The symbol nCx is the "number of combinations of n things taken x at a time". This is the number ways of choosing x distinct objects from a set of n objects, without regard to order. It is given by
nCx = n!/[x!·(n-x)!]
where ! is the factorial symbol.
We want to find the probability that the shipment is accepted. We are told that a shipment will be accepted if at most one tablet doesn't meet the required specifications. That is, the number of defectives must be less than or equal to one.
P(Shipment accepted) = P(X ≤ 1). (In this case, X ≤ 1 if and only if X=0 or X=1)= P(0) + P(1).
So we calculate P(0) (the probability of 0 defective tablets in the shipment), and P(1) (the probability of 1 defective.) Using the formula for the binomial distribution, we have
P(0) = 29C0·(.01)0·(1 - .01)29 - 0.
But 29C0 = 1, so
P(0) = 1·(.01)0·(.99)29 ≅ .74717
Also,
P(1) = 29C1·(.01)1·(1 - .01)29 - 1.
Calculating 29C1, we have
29C1 = 29!/[1!·(29-1)!] = 29, so
P(1) = 29·(.01)1·(99)28
P(1) ≅ .21887
Finally, then, we have
P(Shipment accepted) ≅ .74717 + .21887 ≅ .9660 (to 4 decimal places.)

make x the subject of the formular 6x+a=5(x+t)
The value of x is (5t-a) when the formula is 6x+a=5(x+t).
According to the question,
We have the following information:
6x+a=5(x+t)
Now, from this formula, we have to mark the value of x or in other words, we have to find the value of x.
Now, multiplying 5 into the bracket on the right hand side:
6x+a = 5x+5t
Subtracting 5x from both sides of the equation:
6x-5x+a = 5t
x+a = 5t
Subtracting a from both sides of the equation, we will get the final value of x in terms of t and a:
x = 5t-a
Hence, the value of x is (5t-a) when the formula is 6x+a=5(x+t).

katie has £1200. she gives 1/3 of the money to her sister. Then katie give 1/4 of the remaining money to her brother. how much money does katie have left?
Answer:
£600
Step-by-step explanation:
Katie gives 1/3 of the money to her sister.
1/3 of 1200 is 400, because 1200 divided by 3 is 400. So she gives 400 to her sister, which means she has 1200-400= 800 left.
When she gives 1/4 of the remaining to her brother, that means that we need to figure out how much 1/4 of 800 is. 800 divided by 4 is 200. So Katie gives 200 to her brother.
800 that she has remaining minus the 200 she gives to her brother leaves her with 800-200 = 600
