The Surface area of the triangular prism is 26.88 cm².

The Volume of the triangular prism is 7.68 cm³.

The formulas we would used are:

Surface area of triangular prism = (S1 + S2 + S3)(L) + bh

Volume of triangular prism = 1/2 * base * height * length of prism

Perimeter of the triangular face = (S1 + S2 + S3) = 4.0 + 3.2 + 2.4 = 9.6 cm

Length of prism = 2.0 cm

base of triangular face (b) = 3.2 cm

height of triangular face (h) = 2.4 cm

Plug in the values:

Surface area of triangular prism = (9.6)(2.0) + (3.2)(2.4) = 26.88 cm²

Volume of triangular prism = 1/2 * 3.2 * 2.4 * 2.0 = 7.68 cm³

Answer: To find the decimal expansion of 5/7, we can perform long division as follows:

0.7│5.0

    4 2

 ────

  8 │ 30

    28

  ───

20 │ 200

    196

  ────

      4

Hence, 5/7 = 0.714285... where the digits 714285 repeat indefinitely. To find the maximum number of digits in the repeating block of digits, we can observe that the repeating block will be at most 6 digits long because 7 has a factor of 2 and 5, and therefore 7 divides 10^6 - 1 = 999999.

In fact, we can see that the repeating block in this case has 6 digits, since the digits 714285 repeat indefinitely, and there are 6 digits in this repeating block. Therefore, the maximum number of digits in the repeating block of digits in the decimal expansion of 5/7 is 6.

Step-by-step explanation:

The total amount paid to the finance company if the loan is repaid in 40 years is $317,376.00 (option c).

First, we need to find out how much money the couple borrowed. Since they got financing for 80% of the $150,000 purchase price, they borrowed $120,000 ($150,000 x 0.8 = $120,000).

Next, we need to find the monthly interest rate. Since the interest rate is 6% per year, the monthly interest rate is 0.06/12 = 0.005.

Now we can use the table to find the monthly payment per $1000 of mortgage for a 40-year loan with a 6% interest rate. Looking at the fifth column of the table, we find the entry that corresponds to a 6% interest rate and a 40-year loan, which is 5.86. This means that for each $1000 borrowed, the monthly payment is $5.86.

To find the monthly payment for the couple's $120,000 loan, we multiply the monthly payment per $1000 by 120 (since they borrowed $120,000). So the monthly payment is 5.86 x 120 = $703.20.

Finally, we need to calculate the total amount paid to the finance company over the 40-year period. Since the couple will make 12 payments per year for 40 years, the total number of payments will be 12 x 40 = 480. So the total amount paid will be the monthly payment ($703.20) multiplied by the total number of payments (480). This gives us a total of $317,376.

Therefore, the correct option is (c).

A z-score is a statistical measurement that indicates how many standard deviations an individual value is from the mean - True.

The mean from the value of interest and dividing the result by the standard deviation.

This standardized score provides a way to compare values from different data sets or populations.

For example, if a student's score on a test is 80 and the mean score for the class is 70 with a standard deviation of 5, the student's z-score would be 2.

This means that the student's score is two standard deviations above the class mean. This information can be useful in understanding the student's performance relative to their peers.

Z-scores can also be used to identify outliers or extreme values in a data set. Values with a z-score greater than 3 or less than -3 are considered to be outliers and may warrant further investigation.

In summary, a z-score is a valuable tool in statistical analysis that measures how many standard deviations a value is from the mean. It provides a standardized way to compare values across different data sets and can help identify outliers or extreme values.

lines a and b are perlendicularr and the equation of line a is y=x+3.Therefore, after calculation, the equation of line b is y = -x + 3.

Perpendicular refers to a line, ray, or segment that intersects another line or segment at a right angle, or 90-degree angle. The point of intersection is called the point of perpendicularity and is equidistant from the endpoints of the segment.

An equation of a line is a mathematical representation of a straight line. It can be written in various forms, including slope-intercept form, point-slope form, and standard form, and relates the variables x and y.

According to the given information:

If line a has the equation y = x + 3 and line a is perpendicular to line b, then the slope of line b is the negative reciprocal of the slope of line a.

The slope of line a is 1, so the slope of line b is -1/1, which simplifies to -1.

To find the equation of line b, we need to find the y-intercept (b) using the point-slope form of a linear equation. We can choose any point on line b, but since we don't have any specific point given, we can use the y-intercept of line a, which is 3.

To calculate the experimental probability of rolling a number three on the next roll, we need to use the data given in the problem. Out of the 20 rolls that were performed, the number three was rolled 14 times.

The experimental probability is calculated by dividing the number of times the event occurred (in this case, rolling a number three) by the total number of trials.

So, the experimental probability of rolling a number three on the next roll is:

Mark Twain's quote about breaking down overwhelming tasks into manageable pieces is a valuable lesson for high school students, particularly when it comes to writing. (option d)

In the context of writing, this quote can be particularly helpful. Writing a story or essay can seem like a daunting task, but if you break it down into smaller pieces, it becomes much more manageable. This is where the process of outlining comes in. An outline is essentially a roadmap of your writing, breaking it down into smaller components that you can tackle one at a time.

In mathematical terms, you can think of this process as a series of equations. Each equation represents a small, manageable piece of the overall problem.

By breaking down the problem into smaller equations, you can solve each one individually, which ultimately leads to solving the larger problem. This is similar to how breaking down a writing project into smaller pieces can help you write a well-structured and coherent piece.

The solution to the system by elimination is (-2, 4).

To solve the system using elimination, we need to eliminate one of the variables by multiplying one or both of the equations by a constant.

-6X = 18 - Y

9 = -3X - 8Y

Rewrite as

-6X = 18 - Y

3X = 9 - 8Y

So, we have

-6X = 18 - Y

6X = 18 - 8Y

Now we can add this equations to the second equation to eliminate x:

0 = 36 - 9Y

This gives

9Y = 36

So, we have

Y = 4

Recall that

-6X = 18 - Y

So, we have

-6X = 18 - 4

So, we have

-6X = 12

Divide by 2

X = -2

The Hardy-Weinberg equation is a mathematical formula used to calculate the frequency of alleles (alternative forms of genes) in a population.

It states that the frequency of alleles and genotypes in a population will remain constant from generation to generation in the absence of other evolutionary influences.

The equation is expressed as: p² + 2pq + q² = 1

In this equation, p represents the frequency of the dominant allele in the population, and q represents the frequency of the recessive allele.

The superscripts 2 represent the proportion of individuals in the population that are homozygous for that allele (meaning they have two copies of the same allele), while the 2pq term represents the proportion of individuals that are heterozygous (meaning they have one copy of each allele).

The sum of these terms is always equal to 1, as it represents the entire population.

This equation assumes several conditions: that the population is large, randomly mating, with no mutations, migration, natural selection, or genetic drift.

In reality, these conditions are rarely met, and the Hardy-Weinberg equation serves as a useful model for understanding how allele frequencies can change over time due to various evolutionary influences.
