Answer:

Thickness of rectangle prism is 20 inches.

Step-by-step explanation:

Given:

Surface area of rectangular prism, A =  992 sq inches.

Height, h = 12 inches

Width, w = 8 inches

To find:

Thickness / length of prism, \(l\) = ?

Solution:

First of all, let us learn the formula for surface area of a rectangular prism.

Formula for surface area of a prism is given as:

\(A=2(wl+hl+hw)\)

As there are 6 faces, each face is a rectangle and area of all the faces is considered in the formula. It is just like a cuboid like structure.

Putting all the given values in the formula to find the value of \(l\):

\(992=2(8l+12l+8 \times 12)\\\Rightarrow 496 = 20l + 96\\\Rightarrow 20 l =496-96\\\Rightarrow 20 l =400\\\Rightarrow l = \dfrac{400}{20}\\\Rightarrow l = 20\ inches\)

So, the answer is Thickness of rectangle prism is 20 inches.

Answer:

1200

Step-by-step explanation:

1680/1050 = 1920/x

1680x = 2,016,000

x=1200

There are 1200 vertical pixels.

This is a ratio problem, which uses ratios to relate different items in the question. In a ratio problem, it's important to remember to

1) Write the items in the ratio as a fraction.

2) Make sure that you have the same items in the numerator and denominator.

The first step is to assign variables. Let x = vertical resolution of the 23" monitor.

Write the items in the ratio as a fraction.

\(\frac{horizontal}{vertical} = \frac{1680}{1050} = \frac{1920}{x}\)

Solve the equation.

      Cross multiply:

\(1680*x = 1920 * 1050\)

\(1680x=2016000\)

       Isolate variable x:

\(x=\frac{2016000}{1680}\)

\(x=1200\)

Answer:

Step-by-step explanation:

We reduce 10% to decimal form (0.1) and add to 1 to form its reflective percentile increase. We multiply 18 by 1.1 to get 19.8

Therefore, the probability that the sample mean will be larger than 1,221 is 0.2005.

To find the probabilities for the sample mean of SAT scores, we need to use the normal distribution probability formula, which can be written as:

P (a < X < b) = Φ (b) - Φ (a)

where X is a normal random variable with mean μ and standard deviation σ, a and b are any two values, and Φ is the cumulative distribution function of the standard normal distribution.

The sample mean of SAT scores is also a normal random variable, with a mean equal to the population mean (1,200) and a standard deviation equal to the population standard deviation (200) divided by the square root of the sample size (64). Therefore, the standard deviation of the sample mean is 200 / √64 = 25.

To find the probabilities for each part of the question, we need to standardize the sample mean by subtracting the mean and dividing by the standard deviation, and then use a table or a calculator to find the values of Φ. Here are the steps for each part:

(a) the probability that the sample mean will be larger than 1,221

P (X > 1,221) = P (Z > (1,221 - 1,200) / 25)

P (X > 1,221) = P (Z > 0.84)

P (X > 1,221) = 1 - P (Z < 0.84)

P (X > 1,221) = 1 - Φ (0.84)

P (X > 1,221) = 1 - 0.7995

P (X > 1,221) = 0.2005

(b) the probability that the sample mean will be less than 1,231

P (X < 1,231) = P (Z < (1,231 - 1,200) / 25)

P (X < 1,231) = P (Z < 1.24)

P (X < 1,231) = Φ (1.24)

P (X < 1,231) = 0.8925

Therefore, the probability that the sample mean will be less than 1,231 is 0.8925.

(c) the probability that the sample mean will be between 1,200 and 1,215

P (1,200 < X < 1,215) = P ((1,200 - 1,200) / 25 < Z < (1,215 - 1,200) / 25)

P (1,200 < X < 1,215) = P (0 < Z < 0.6)

P (1,200 < X < 1,215) = P (Z < 0.6) - P (Z < 0)

P (1,200 < X < 1,215) = Φ (0.6) - Φ (0)

P (1,200 < X < 1,215) = 0.7257 - 0.5

P (1,200 < X < 1,215) = 0.2257

Therefore, the probability that the sample mean will be between 1,200 and 1,215 is 0.2257.

(d) the probability that the sample mean will be greater than 1,200

P (X > 1,200) = P (Z > (1,200 - 1,200) / 25)

P (X > 1,200) = P (Z > 0)

P (X > 1

The representation that would be best for determining the two values that 50 % of the data will lie is C. Interquartile Range

The interquartile range (IQR) is a measure of the dispersion of a dataset. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. The interquartile range provides a measure of the spread of the middle 50% of the data, as opposed to the range which measures the spread of the entire dataset.

The interquartile range is useful because it is not affected by outliers or extreme values, unlike the range. It is therefore a more robust measure of dispersion and is often used in statistics and data analysis.

The cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.

To find the cheapest price Sam would pay for 10kg of cake for the party, we need to compare the prices of the available cakes and determine the most cost-effective option.

At Mega Mart, a 5kg cake costs $2500.

Therefore, the price per kilogram for this cake is:

Price per kilogram at Mega Mart = $2500 / 5kg = $500/kg.

At the same time, a 2kg chocolate cake costs $1200.

So, the price per kilogram for this cake is:

Price per kilogram for the chocolate cake = $1200 / 2kg = $600/kg.

Now, let's calculate the total price for 10kg of cake from each option:

Total price at Mega Mart for 10kg = $500/kg \(\times\) 10kg = $5000.

Total price for 10kg of chocolate cake = $600/kg \(\times\) 10kg = $6000.

Comparing the two options, we see that the Mega Mart cake is the more cost-effective choice.

Sam would pay a total of $5000 for 10kg of cake from Mega Mart, whereas the chocolate cake would cost $6000 for the same quantity.

Therefore, the cheapest price Sam would pay for 10kg of cake for the party is $5000 from Mega Mart.

In summary, Sam would pay the cheapest price of $5000 to purchase 10kg of cake for the party from Mega Mart.

The biconditional statement for the given conditional statement would be:

2x = 18 if and only if x = 9.

The given conditional statement "If 2x = 18, then x = 9" can be represented symbolically as p → q, where p represents the statement "2x = 18" and q represents the statement "x = 9".

To form the biconditional statement, we need to determine if the converse of the conditional statement is also true. The converse of the original statement is "If x = 9, then 2x = 18". Let's evaluate the converse statement.

If x = 9, then substituting this value into the equation 2x = 18 gives us 2(9) = 18, which is indeed true. Therefore, the converse of the original statement is true.

Based on this, we can write the biconditional statement:

2x = 18 if and only if x = 9.

The biconditional statement implies that if 2x is equal to 18, then x must be equal to 9, and conversely, if x is equal to 9, then 2x is equal to 18. The biconditional statement asserts the equivalence between the two statements, indicating that they always hold true together.

In summary, the biconditional statement is a concise way of expressing that 2x = 18 if and only if x = 9, capturing the mutual implication between the two statements.

The electrical resistance varies directly as the square of the voltage and inversely as the electric power, and the equation that relates them isR ∝ V²/PR = kV²/PR = V²/P. This relationship can be used to calculate the electrical resistance of the wire or component for any given voltage and power.

The electrical resistance is the measure of the difficulty in passing electric current through a wire or an electrical component. It depends on various factors, such as the material, dimensions, and temperature of the wire.The given statement says that the electrical resistance varies directly as the square of the voltage and inversely as the electric power.

In mathematical terms, this relationship can be expressed as R ∝ V²/PR = kV²/P where R is the electrical resistance, V is the voltage, P is the electric power, and k is the constant of proportionality. The constant k depends on the material, dimensions, and temperature of the wire or component.

The given statement implies that the constant k is the same for the given wire or component, and it is not affected by the voltage or the power.To find the value of k, we can use the given values of V, P, and R.

According to the statement, if the voltage is 20 volts and the electric power is 5 watts, then the electrical resistance is 80 ohms. Therefore,R = kV²/PR = k(20²)/5R = 400k/5R = 80 ohms

Substituting the value of R in the equation, we get80 = 400k/5k = (80 x 5)/400k = 1. Therefore, the equation that relates the electrical resistance, voltage, and power isR = V²/PThe constant of proportionality k is 1 for the given wire or component.

Therefore, the electrical resistance varies directly as the square of the voltage and inversely as the electric power, and the equation that relates them isR ∝ V²/PR = kV²/PR = V²/P. This relationship can be used to calculate the electrical resistance of the wire or component for any given voltage and power.

The mean and standard deviation of the random variable with the given discrete probability distribution are:

Mean = 151.5
SD = 17.224

Here is how we calculated the above

Using the formula for the mean of a discrete probability distribution

μ = Σ (x * P (x) )

Here,

Σ = Sum of all possible values of x

μ =  mean

So

μ = (120 x 0.30) + (150 x 0.30) + (170 x  0.15) + ( 180   x 0.25)

μ = 36 + 45 + 25.5 + 45
μ = 151.5


To compute the standard deviation,  we used the formula

σ = √[Σ ( (x - μ)² * P(x )) ]

σ = √[( (120 - 151.5)² x 0.30) + (( 150 - 151.5)² x  0.30) + ((1 70 - 151.5)² * 0.15) + ((180 - 151.5)² * 0.25 )]

Simplified, this results in

The overall percentage increase in the account balance from the initial deposit at the end of 10 years is $786.25 which is 87.36%.

What is compound interest?

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate is raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

When the amount compounds quarterly, it means that the amount compounds 4 times in a year. i.e., n = 4. We use this fact to derive the quarterly compound interest formula. Thus, the quarterly compound interest formula is:

A = P (1 + r/4)4t

Nicolas deposited $900 into an account that pays 6.48% annual interest compounded annually.

The balance in the account after 10 years was $1686.25.

INCREMENT in 10 years is 1686.25-900 = $786.25

So the percentage increment will be 900-786.25/ 900 = 87.36%

Hence, the overall percentage increase in the account balance from the initial deposit at the end of 10 years is $786.25 which is 87.36%.
