Answer:

Step-by-step explanation:

4.1.1 "I am fifty years old" is an example of a discrete variable, as age is typically measured in whole numbers, not fractions or decimals.

4.1.2 "I can drink 400.5 ml of juice in a minute" is an example of a continuous variable, as the amount of juice consumed can be any value along a continuous range of possible values, including fractional amounts.

4.1.3 "I have 2 brothers and 1 sister" is an example of a discrete variable, as the number of siblings is typically measured in whole numbers.

In summary, 4.1.1 is a discrete variable, 4.1.2 is a continuous variable, and 4.1.3 is a discrete variable.

You have a fraction of 5/4 of the required tickets. You don't need more tickets for the souvenir.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Any number can be expressed as fractions.

Given that,

Percentage of tickets you have = 125%

125% can also be written as 125 / 100

125% = 125 / 100

         = (25 × 5) / (25 × 4)

         = 5/4, which is the required fraction.

Actual number of tickets needed = 100%

You have 25% = 25/100 = 1/4 more tickets for the souvenir.

So you don't need more tickets.

4,5,6;well, considering orange seems most abundant there would be at least a 3/4ths chance of getting orange a 2/4ths chance of getting pink and for the other colors a 1/4th chance of getting yellow or red

Step-by-step explanation:

Answer:

Let x be the number of tickets sold.

Jaelyn's account balance after selling tickets: 150 + 58x

Erik's account balance after selling tickets: 480 + 6x

For both accounts to have the same amount, we set their balance equal to each other and solve for x:

150 + 58x = 480 + 6x

52x = 330

x = 330/52 = 6.25

So 6.25 tickets had to be sold before both accounts had the same amount of money.

The distance of barn B from the north end of pipe 27 is 258 ft to the nearest foot.

Let's call the distance from Barn B to the north end of pipe 2 as "d".

The distance from the barn to the south end of pipe 1 is 111 ft, the distance from there to the south end of pipe 2 is 23 ft, and the distance from the barn to the north end of pipe 1 is 127 ft.

So the total distance from barn B to the south end of pipe 2 is 111 + 23 = 134 ft.

Since the distance from barn B to the north end of pipe 1 is 127 ft, then the distance from the north end of pipe 1 to the north end of pipe 2 is d - 127 ft.

Since the distance from barn B to the south end of pipe 2 is 134 ft, then the distance from the south end of pipe 2 to the south end of pipe 1 is 134 - d ft.

Now, two right triangles with legs (d - 127) ft and (134 - d) ft.

By the Pythagorean Theorem, we have: (d - 127)² + (134 - d)² = 25²

Expanding and simplifying the equation gives us:

d² - 260d + 17296 = 625

d² - 260d + 16671 = 0

Using the quadratic formula:

d = (260 ± √(260² - 4 x 16671)) / 2

d = (260 ± √(677600 - 66768)) / 2

d = (260 ± √(61032)) / 2

d = (260 ± 246.9) / 2

d = 258 ± 123.5

So, the distance from barn B to the north end of pipe 2 is 258 ft or 381 ft.

Since the question asks to round the answer to the nearest foot, we can conclude that the answer is 258 ft.

The real interest rate is the interest rate that has been adjusted for inflation.

By reducing the principal by both the interest rate, by duration of time, and other factors, simple interest is derived. Simple return = principal plus interest plus hours is really the concept used in marketing. The easiest way to compute tax is by using this procedure. The most typical method of calculating income is as a portion of the outstanding sum. For illustration, if he borrows $100 from a buddy and pledges to pay back the loan at 5% interest, he will just pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you should pay interest, and you must collect interest when they lend it. Typically, interest is computed as a percentage of the loan total. The loan's interest is the name given to this percentage.

The interest rate charged on a loan expressed in dollars is called the nominal interest rate. The interest rate after accounting for inflation is known as the real interest rate. The nominal interest rate less the inflation rate equals the real interest rate.

Step-by-step explanation:

Answer: Yes, I can solve this problem using a system of equations. Let n be the number of nickels and q be the number of quarters. Then we can write two equations:

The total number of coins is 25: n + q = 25.

The total value is $3.85: 0.05n + 0.25q = 3.85

We can solve this system of equations using substitution or elimination. Let's use substitution:

From equation (2), we can solve for n: n = (3.85 - 0.25q)/0.05.

Substitute this expression for n into equation (1): (3.85 - 0.25q)/0.05 + q = 25.

Multiply both sides by 0.05 to clear the denominators: 3.85 - 0.25q + 0.05q = 25 * 0.05.

Simplify the left side: 3.85 = 1.25q.

Divide both sides by 1.25 to solve for q: q = 3.08

Substitute this value for q into equation (1) or the expression for n from step (1) to find n: n = 25 - q = 25 - 3.08 = 21.92

Since n and q represent the number of coins, we round them down to the nearest whole number. So, there are 21 nickels and 3 quarters.

The probability that the postman is never bitten by a dog is equal to the product of all qi's from i=1 to infinity, which is equal to (1-α)^∞. This is equal to 0 since α is a positive number.

The probability that the postman is never bitten by a dog is given by P(X > n), where X is the number of days until the postman sustains his first bite. This probability can be expressed as the product of all of the qi's from i=1 to n, which is equal to (1-α)^n, where qn = α for all n, and 0 < α < 1. The probability that the postman is never bitten by a dog is equal to the product of all qi's from i=1 to infinity, which is equal to (1-α)^∞. Since 0 < α < 1, (1-α)^∞ is equal to 0, meaning that the probability that the postman is never bitten by a dog is 0. This is because as n increases, the probability that the postman is not bitten by a dog on Day n decreases, and as n approaches infinity, it approaches 0.

Answer:

Equation: y = 1800 - 120x

Step-by-step explanation:

y = 1800 - mx           Where x = months after purchase of computer

                                            y = balance remaining

1800 = y-intercept because this is your initial balance remaining as it is the actual price of the computer.

The coefficient of ‘m’ will be negative for this equation because the value of y decreases as x increases. (NOTE:  y is NOT indirectly proportional to x as the line of the equation does not pass through the origin)

Next step is to determine 'm’:

m = slope of equation

Two sets of x and y values have been provided:

[tex](x_{2}, y_{2}) = (3, 1440)[/tex]

[tex](x_{3} ,y_{3})= (6, 1080)[/tex]

Use any set and substitute in the slope-intercept equation to determine the value of m:

1080 = 1800 - 6m

All the like terms are brought together and m needs to be isolated:

6m = 1800 - 1080

6m = 720

m = [tex]\frac{720}{6}[/tex]

m = 120

Therefore:
