The answer is [tex]L = 624 cm^2; S = 944 cm^2[/tex]  where L is the lateral area and S is the surface area of a right rectangular prism.

The lateral area of a right rectangular prism is given by the formula:

[tex]L = 2(lw + bh)[/tex]

where l and b are the length and width of the base, and h is the height of the prism.

The surface area is given by the formula:

[tex]S = 2(lb + bh + lh)[/tex]

For the given prism with a base of 12 cm by 10 cm and a height of 16 cm, the lateral area is:

[tex]L = 2((12 cm)(10 cm) + (12 cm)(16 cm)) \\= 2(120 cm^2 + 192 cm^2)\\= 2(312 cm^2)\\= 624 cm^2.[/tex]

The surface area is:

[tex]S = 2((12 cm)(10 cm) + (10 cm)(16 cm) + (12 cm)(16 cm))\\ = 2(120 cm^2 + 160 cm^2 + 192 cm^2) \\ = 2(472 cm^2) \\ = 944 cm^2.[/tex]

So the answer is [tex]L = 624 cm^2[/tex] ; [tex]S = 944 cm^2[/tex] .

Answer:

x=16/squared

Step-by-step explanation:

divide each term in 3xsquared = 48 by 3squared and simplify.

Answer:

If squaring a number means multiplying it by itself, according to this rule, you multiply 3 by "x" and then multiply "x" by itself to get 48. In this scenario, you divide 3 by blank squared to get blank. In this case, you set up this problem with division, so we are dividing 3 times blank squared by 3. Whatever the blank value is, we know this equation equals 48, so you must create a mirrored equation of 48 divided by 3. Now that you've divided 48 by 3, that is 16, right? So 16 will be the equivalent of blank squared, or "x" squared. For blank squared, since we are dealing with algebra, the next step is to use square roots using what we know. We know that 16 is composed of 4 squared, right? So turn 4 squared into a radical of √4². This radical is equal to 4, because "radical" = "number" as long as that number is more than or equal to 0. So, in conclusion, x is 4.

The area of the enclosed region in the diagram is 20 square units.

The area of the enclosed region in the diagram can be calculated using the formula A = lw, where A is the area, l is the length, and w is the width. The length is 5 units and the width is 4 units, so A = lw = 5 X 4 = 20 square units.

To calculate the area, we first need to find the length and width of the enclosed region. The length can be found by measuring the longest side, which is the bottom side. This side has a length of 5 units. The width can be found by measuring the shorter side, which is the left side. This side has a width of 4 units.

Once we have the length and width, we can use the formula A = lw to calculate the area. In this case, A = 5 X 4 = 20 square units. Therefore, the area of the enclosed region in the diagram is 20 square units.

Answer:

Option B)

Step-by-step explanation:

The inequalities are y ≥ (2/3)x + 1 and y < (-1/4)x + 2 and (−6, −3) satisfied the inequality.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given phrase,

y is greater than or equal to two-thirds times x plus 1 ⇒ y ≥ (2/3)x + 1

y is less than negative one-fourth times x plus 2 ⇒ y < (-1/4)x + 2

Substitute, point (−6, −3)

-3 ≥ (2/3)(-6) + 1

-3 ≥ -3  

Substitute in second inequality,

-3 < (-1/4)(-6) + 2

-3 < 7/2

Hence "The inequalities are y ≥ (2/3)x + 1 and y < (-1/4)x + 2 and (−6, −3) satisfied the inequality".

There is a 95% chance that the true mean number of hours of sleep per day for all students in the school falls within this range

To calculate the 95% confidence interval for the mean number of hours of sleep per day of a random sample of 50 students from a large high school, you would need to follow these steps:

Calculate the mean of the sample by adding up all the hours of sleep reported and dividing by the sample size (n).

Calculate the standard deviation (σ) of the sample by taking the square root of the sum of squares of the differences between the sample values and the mean divided by n1.

Calculate the standard error (SE) by dividing the standard deviation by the square root of n.

Calculate the margin of error (ME) by multiplying the standard error by the critical value of 1. 96.

Calculate the confidence interval by adding and subtracting the margin of error from the mean. This will give you the lower and upper bounds of the confidence interval.

Therefore, the 95% confidence interval for the mean number of hours of sleep per day of a random sample of 50 students from a large high school is (6. 73, 7. 67). This means that there is a 95% chance that the true mean number of hours of sleep per day for all students in the school falls within this range

Binomial theorem is the method of expanding an expression consisting of two terms raised to any power.

Using the expansion of Binomial theorem, we can write,

(2 + 3x)ⁿ = ⁿC₀ (2)ⁿ (3x)⁰ + ⁿC₁ (2)ⁿ⁻¹ (3x)¹ + ⁿC₂ (2)ⁿ⁻² (3x)² + ⁿC₃ (2)ⁿ⁻³ (3x)³ + ⁿC₄ (2)ⁿ⁻⁴ (3x)⁴ + .............

Coefficient of x³ is  ⁿC₃ (2)ⁿ⁻³ (3)³ and the coefficient of x⁴ is ⁿC₄ (2)ⁿ⁻⁴ (3)⁴.

Ratio of these coefficients is 8 : 15.

[ⁿC₃ (2)ⁿ⁻³ (3)³] / [ⁿC₄ (2)ⁿ⁻⁴ (3)⁴] = 8 / 15

Simplifying,

(4 × 2) / [(n - 3) 3] = 8/15

8 / 3n - 9 = 8 /15

the price at each level of demand can be calculated by p = D(q) = 28 - 2.25q.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, Given a function that defines the price for a certain model of a youth wristwatch is related by p = D(q) = 28 - 2.25q.

Thus,

A) The demand function is p = 28 - 2.25q.

When demand q is 0,

price is p = 28 - 2.25*0 = $28

B) When demand q is 400,

price is p = 28 - 2.25*4 = $19.

C) When the price is 10,

we have 10 = 28 - 2.25q or 2.25q = 18.

This gives q = 800 or 8 in hundreds

D) Graph of the demand function will have a vertical intercept of 28 (When q = 0, the value of p is 28) and a horizontal intercept of 12.44.

Here the first graph in part A is correct because it fits the intercepts

E) Supply function is p = 1.25q.

When the price is 0,

the quantity supplied is 0.

F) When the price is 17,

quantity supplied is 17 = 1.25q or q* = 13.6 of 1360 in hundreds

G) The vertical intercept is 0.

The graph will be similar to the one in option A because it matches both demand and supply equations.

H) Equilibrium occurs when demand and supply are equal

28 - 2.25q = 1.25q

28 = 3.5q

q* = 28/3.5 = 8 or 800 watches

price is p = 1.25*8 = $10.

To construct frequency and relative frequency distributions, count number of students for each major and divide by total number of students (30) to find the relative frequency.

Use the frequency and relative frequency data to create a bar chart and a pie chart to visualize the data. To construct a frequency distribution and bar chart for the thirty students in the School of Business, we need to count the number of occurrences of each major and create a table. For example, if 9 students chose Management as their major, 9 would be the frequency for Management. We can then plot the frequencies on a bar chart, with each major on the x-axis and its frequency on the y-axis. The bar chart visually represents the distribution of the data.

A relative frequency distribution is a frequency distribution expressed as a proportion or percentage of the total number of observations. To create a relative frequency distribution, we divide each frequency by the total number of students (30 in this case) and multiply by 100%. The relative frequencies can then be used to construct a pie chart, where each major is represented as a wedge or slice of the pie, proportional to its relative frequency. The pie chart visually represents the distribution of the data as a whole.

it is true in practice, we frequently use a continuous distribution to approximate a discrete one when the number of values the variable can assume is countable but large.

The continuous category of random variables refers to those whose spaces are unions of intervals or intervals rather than a countable number of points. When the sample size is too big to treat each individual event discretely or when a variable does not occur in discrete intervals, continuous distributions are employed as probability models (please see Discrete Distributions for more details on discrete distributions). The main distinction between continuous and discrete distributions is that, while discrete distributions deal with smaller sample populations and cannot be treated as if their random variable values are on a continuum (from negative infinity to positive infinity), continuous distributions deal with a sample size so large that its random variable values are treated on a continuum (from negative infinity to positive infinity).

a) The error first appears between Steps 2 and 4.

b) The value of the expression is given by: 5^(-4) = 1/625.

The power of a power rule is used when a single base is elevated to multiple exponents.

Then the simplified expression is obtained keeping the base, while the exponents are multiplied.

The numerator is simplified as follows:

25^(-4) = 5²^(-4) = 5^(2 x -4) = 5^(-8).

The denominator is given as follows:

5²^(-2) = 5^(-4).

When two terms have the same base and different exponents and are divided, we keep the base and subtract the exponents, hence:

5^(-8)/[5^(-4)] = 5^(-8 - (-4)) = 5^(-4) = 1/(5^4) = 1/625.

The merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons.

The merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons. This is because we must compare each element in both lists in order to sort them. So a total of m+n comparisons are required in the worst case scenario.

This can be visualized by using a formula: n + m = m+n. This formula can be used to calculate the total number of comparisons required.

For example, if m = 10 and n = 15, then 10 + 15 = 25. This means that 25 comparisons would be required in order to sort the two lists.

Thus, the merging of two sorted lists of sizes m and n into a sorted list of size m+n requires O(m+n) comparisons. This is because we must compare each element in both lists in order to sort them.

If x must be a number. The same outcome is obtained by increasing x by 20% as well as by decreasing that product of four with x by 5. x has the value of 25/14.

Let's look up an expression for raising x by 20%. This might be shown as x + 20%. x = x + 0.2x = 1.2x = 6x/5.

The two expressions must now be set to be equal to each other.

6x/5 = 4x - 5

Add 6x/5 to both sides and subtract. To make 4x and 6x/5 have a similar denominator, we can rephrase 4x as 20x/5.

0 = 20x/5 - 6x/5 - 5 = 14x/5 - 5

0 = 14x/5 - 5

We can now increase both sides by five.

5 = 14x/5

Now that we have the reciprocal of 14/5, 5/14, we may multiply either sides by this number.

5(5/14) = (14x/5)(5/14) = x

25/14 = x
