The additional time it will take for the temperature of the liquid to decrease to 35°F after 4 minutes is 21.54 minutes (rounded to two decimal places).

Given that: Initial temperature of the liquid, T₁ = 170°F.Final temperature of the liquid, T₂ = 35°F.Constant temperature of the freezer, T = 25°F.

Time taken to decrease the temperature of the liquid from 170°F to 70°F, t₁ = 4 minutes.

The rate of change of temperature, R = (T₁ - T) / t₁ = (170°F - 25°F) / 4 minutes = 111.25°F/minute.

In the freezer, the rate of change of temperature is constant. Hence, the rate of change of temperature after 4 minutes can be used to calculate the additional time it will take for the liquid's temperature to decrease from 70°F to 35°F:R = (T₂ - T) / t₂ = (35°F - 25°F) / t₂t₂ = (10°F / R) = (10°F / 111.25°F/minute) = 0.089728 minutes ≈ 5.38 seconds.

Adding this time to the initial 4 minutes, we have the additional time it will take for the temperature of the liquid to decrease to 35°F after 4 minutes: t = t₁ + t₂ = 4 minutes + 0.089728 minutes ≈ 4.089728 minutes or 4 minutes 5.38 seconds.

The additional time it will take for the temperature of the liquid to decrease to 35°F after 4 minutes is 21.54 minutes (rounded to two decimal places).

Chance is 1/10

Given that the die has 20 different numbers, ranging from 1-20, we are to determine the chance that the top side will be either a 9 or a 10.When throwing a die with a different number of faces or sides, each face has an equal chance of showing up as the top side. Thus, to determine the chance that the top side will be either a 9 or a 10, we need to find the probability of rolling a 9 or 10.To calculate the probability of a single event occurring, we divide the number of favorable outcomes by the total number of possible outcomes. Thus, in this case, the probability of rolling a 9 or a 10 would be:Probability of rolling a 9 or a 10= number of favorable outcomes/ total number of possible outcomesNumber of favorable outcomes: 2 (since there are only 2 sides of the die that have a 9 or a 10)Total number of possible outcomes: 20 (since there are 20 different numbers on the die)Probability of rolling a 9 or a 10 = 2/20 = 1/10Therefore, the chance that the top side will be either a 9 or a 10 is 1/10.

In order to have a potential value of $12,000 at a simple rate of interest of 8.0% after 6 years, the current value you must invest is therefore approximately $8,108.11.

A formula called Simple Interest (S.I.) is used to determine how much interest will be charged on a certain principal sum of money at a specific interest rate. For instance, if a person borrows Rs. 5000 for two years at a rate of 10 p.a., they will be compelled to pay S.I. on the whole amount borrowed during those two years.

For simple interest, use the formula:

A = P(1 + rt)

where r is the interest rate, t is the amount of time in years, A represents the future value, P is indeed the present value, and so on.

This formula can be changed to account for P:

P = A / (1 + rt)

By entering the specified values, we obtain:

P = 12,000 / (1 + 0.08 x 6)

P = 12,000 / 1.48

Hope has 6 nickels (x) and 10 quarters (x + 4).

How many of each coin Hope has if she has 4 more quarters than nickels and they have a combined value of 280 cents. To solve this problem, we can use algebraic equations.

Let's assume the number of nickels Hope has is x. Then, the number of quarters she has would be x + 4.

Now, we need to find the total value of the coins. Each nickel is worth 5 cents, so the total value of nickels is 5x cents. Similarly, each quarter is worth 25 cents, so the total value of quarters is 25(x + 4) cents. The combined value of the coins is 280 cents, so we can set up an equation:

5x + 25(x + 4) = 280

Simplify and solve for x:

The equation of the line parallel to y = (1/3)x + 4 and passing through (-6, 1) is y = (1/3)x + 3.

To find the equation of a line parallel to y = (1/3)x + 4 and pass through the point (-6, 1), we can use the fact that parallel lines have the same slope. The slope of the given line is 1/3, so the slope of the parallel line must also be 1/3.

Now we have the slope (m = 1/3) and a point on the line (-6, 1), so we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Plugging in the values, we get:

y - 1 = (1/3)(x - (-6))

A random variable is a variable whose possible values are determined by chance, while a discrete random variable can only take on certain values, and a continuous random variable can take on any value within a given range

There are two types of random variables: discrete random variables and continuous random variables.

The difference between these two types of random variables is as follows:

Discrete random variables: A discrete random variable is one that can only take on a finite or countably infinite number of distinct values. These values are usually represented by integers.

Examples of discrete random variables include the number of students in a class, the number of cars in a parking lot, or the number of heads that come up when a coin is flipped. In other words, a discrete random variable is one that can be counted.

Continuous random variables: A continuous random variable is one that can take on an infinite number of values, and these values can be represented by any real number within a given interval.

Examples of continuous random variables include height, weight, temperature, and time. In other words, a continuous random variable is one that can be measured.

Continuous random variables are usually represented by a function called the probability density function, which describes the likelihood of any given value occurring within the given interval.

Let X be the number of buyers who prefer green among the 16 selected. We need to find P(X ≥ 4).

Using a binomial probability table or calculator, we can find:

P(X ≥ 4) = 1 - P(X < 4)

= 1 - P(X ≤ 3)

= 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3)]

= 1 - [0.1233 + 0.2854 + 0.3028 + 0.1854]

= 0.1031 (rounded to 4 decimal places)

Therefore, the probability that at least 4 buyers would prefer green among the 16 selected is approximately 0.1031.

Answer:

The balanced equation that represents an endothermic reaction is:

2 CH4 (g) + 2 O2 (g) → 2 CO2 (g) + 2 H2O (g)

This is because the reactants (CH4 and O2) have a higher bond energy than the products (CO2 and H2O), meaning that energy must be absorbed in order to break the bonds and form the products. As a result, the reaction is endothermic.
