The probability of not paying any amount for the purchased DVD players as per the condition of 1 or more defective is equal to 0.9029.
As given in the condition,
Number of DVD players purchased by a retailer = 240
Number of defective DVD players = 7
Number of non- defective DVD players = 233
Number of DVD players chosen randomly for test = 5
Condition:
If 1 or more DVD players are defective then all players are free of charges.
Total number success rate for 5 DVD to be defective 'p' = 5 / 240
= 1 / 48
Here value of n = 5
Probability of non defective DVD is equal to:
= 1 - ( 47/ 48 )⁵
= 0.09708
Probability of 1 or more defective DVD's are
= 1 - 0.09708
= 0.9029
Therefore, the probability of not to pay any amount for DVD players is equal to 0.9029.

How can you summarize the ruler placement postulate? you can measure the between points a and b by using as zero.
The summary of the ruler placement postulate is: A direct relationship exists between the set of points on the line and the collection of real numbers, where each point is matched to a single real number and The magnitude of the gap between two points is equal to the absolute value of the subtraction of the two associated values.
The ruler placement postulate states that if two points are given, it is possible to measure the distance between them by taking the point of reference as zero. This means that any point can be chosen as an origin, and the distance between the two points can be calculated by measuring the number of units between them. This postulate also applies to curves, and the distance between two points on a curve can be measured by taking a point of reference as zero and measuring the number of units between them. This postulate is essential in the measurement of distances between points and curves in geometry.

Complete the following questions.
Winona and Takoda are shopping for a present for their mother. The chart shows several possible presents. There is no sales tax in the state where they live.
a. Write two expressions in terms of d to show how much Winona and Takoda would pay in total if they buy their mother the set of power tools.
b. Let the value of d equal $79.00. Calculate the total cost of each of the possible presents for the value you chose. Then write a sentence telling Winona and Takoda which preset to buy for their mother if they want to spend the least amount of money.
a) The expressions are given as follows:
Power tools: 0.85d.Water skis: 0.75(d + 15).Jewelry: 0.9(d - 5).b) The total cost for each present is of:
Power tools: $67.15.Water skis: $69.56.Jewelry: $63.Hence the present that they can buy with the least amount of money is:
Jewelry.
How to obtain the costs?The costs are found applying the proportions in this problem.
As a function of d, the functions are found multiplying the decimal equivalents of each discount by the cost expression.
The decimal equivalents of each discount are given as follows:
Discount of 15% -> 0.85, as 85% of the price is paid.Discount of 25% -> 0.75, as 75% of the price is paid.Discount of 10% -> 0.9, as 90% of the price is paid.Then the actual costs are calculated replacing the instances of d in each item with the numeric value d = 79.

At the end, the distance to the car will be 17 miles, and the distance that they walked is 13 miles.
How many miles are there?We want to find the total distance at which the hikers are at the end.
Notice that each little square represents one mile. And the line ends at two little squares above the marking of 15 miles, then the distance to the car at the end is:
15mi + 2 mi = 17 miles.
We also could want to find the distance they walked on the given graph. To find that, we need to take the difference between the final distance and the initial distance.
The final distance is 17 miles, we already know this, and the initial distance is the y-intercept, which in this case is 4 miles.

Jacob went to the grocery store and bought bottles of soda and bottles of juice. Each bottle of soda has 25 grams of sugar and each bottle of juice has 10 grams of sugar. Jacob purchased a total of 12 bottles of juice and soda which collectively contain 240 grams of sugar. Determine the number of bottles of soda purchased and the number of bottles of juice purchased.
The number of bottles of soda is 4 and the number of bottles of juice purchased is 8.
We know that linear system of equation in two variables is required to solve the problem. Let suppose number of bottles of soda purchased by Jacob is x and number of bottles of juice purchased by Jacob is y
Since, it is given that Jacob bought 25 bottles in total, it means
=>x + y=12-----(eq1)
Also, it is given that total amount of sugar is 240grams.Now,amount of sugar present in soda bottle is 25x and amount of sugar present in juice bottles is 12y
Therefore,25x + 12y=240-----(eq2)
On solving eq1 and eq2,we get
=>x+y=12
and 25x+10y=240
Using elimination technique to solve, make x terms coefficient equal.
Multiplying eq1 by 25,we get
=>25x + 25y=25×12
=>25x +25y=300------(eq3)
Using eq3 and eq4,we get
=>25x+25y=300
and 25x+10y=240
Cancelling x terms, we get
=>15y=60
=>y=(60/15) grams
=>y=4 bottles
Now, putting value of y in eq1 ,we get
=>4+y=12
=>y=12-4
=>y=8bottles.
Hence, required value of number of bottles of soda is 4 and number of bottles of juice is 8.

Gavin deposited $12,000 at 2% interest mounted quarterly what is the value after 16 years round to the nearest cent
Answer:
final amount = $16512.36
Step-by-step explanation:
The question asks us to find the value of Gavin's deposit of $12,000 after 16 years, given that the interest rate of 2% is compounded quarterly.
To do this, we have to use the following formula for compound interest:
[tex]\boxed{A = P(1 + \frac{r}{n})^{nt}}[/tex],
where:
A → amount at the end
P → principal (original) amount
r → interest rate (in decimal)
n → number of times per year that the interest is compounded
t → time (in years).
From the question, we know that the initial amount deposited is $12,000. Therefore, P = 12000. We also know that the interest rate is 2%, but the formula requires the rate to be in decimal, so r = 0.02. The time for which the money is deposited is 16 years, and therefore, t = 16. We are told that the interest is compounded quarterly, that is, every 3 months. This means that the interest is compounded 4 times yearly, so n = 4.
From the above information and formula, we can calculate the final amount:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
⇒ [tex]A = 12000(1 + \frac{0.02}{4})^{4 \times 16}[/tex]
⇒ A = $16512.36
Therefore, the final amount after 16 years is $16512.36.

Number of games did Carly NOT play is 22.
How to calculate percentage?
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given:
Total number of games = 40
It is given that she had played in 45 percent of the 40 games the team played.
Number of games she played = 45% of 40
= [tex]\frac{45}{100}\times 40= 18[/tex]
