Step-by-step explanation:

The rate of VAT on the vacuum cleaner is 15%

The given parameters are:

Selling price = Rs 12000

Discount = 12%

Amount Paid = 12144

The amount paid is calculated as:

Amount Paid = Selling Price * (1 - Discount) * (1 + VAT)

So, we have

12144 = 12000 * (1 - 12%) * (1 + VAT)

Evaluate the difference

12144 = 12000 * 0.88 * (1 + VAT)

Evaluate the product

12144 = 10560 * (1 + VAT)

Divide both sides by 10560

1.15 = (1 + VAT)

Subtract 1 from both sides

VAT = 0.15

Express as percentage

VAT = 15%

Hence, the rate of VAT on the vacuum cleaner is 15%

In the given case, the required critical value is 2.485.

To find the critical value t* for a t-distribution with a sample size of 26 and a probability of 1% for values greater than t*, we need to consider the degrees of freedom (df) and the given tail probability.

In this case, the degrees of freedom (df) will be equal to the sample size minus 1, which is 26 - 1 = 25. The tail probability is given as 1%, which is equal to 0.01.

To find the critical value t*, you can use a t-distribution table or calculator. Look for the value at the intersection of the row with 25 degrees of freedom and the column corresponding to a tail probability of 0.01.  Using a t-distribution table or calculator, the critical value t* is approximately 2.485. Therefore, the required critical value is 2.485.

Note: The question is incomplete. The complete question probably is: What is the value of t*, the critical value of the t distribution for a sample of size 26, such that the probability of being greater than t* is 1%? The required critical value is ____________ .

Problem 1.2 in reading graphs and tables is about understanding how to interpret data that is presented in visual form. In order to effectively read graphs and tables, it is important to understand the type of data that is being presented and the purpose of the graph or table.

Graphs are visual representations of data that can show trends, patterns, and relationships. Tables are also useful tools for presenting data, especially when dealing with numerical values.
One of the key skills in reading graphs and tables is to be able to identify the main features of the data. This can include the axes, the labels, and the data points themselves. For example, a line graph might show the relationship between two variables over time. The x-axis would typically represent time, and the y-axis would represent the variable being measured. By examining the data points on the graph, it is possible to see trends and patterns that might not be immediately apparent from looking at the raw data.
Tables can also be useful for presenting data, particularly when dealing with numerical values. Tables typically have rows and columns, with each row representing a different observation and each column representing a different variable. Tables can be useful for comparing different observations or variables, or for displaying summary statistics such as means, medians, or standard deviations.
Overall, reading graphs and tables requires careful attention to detail and an understanding of the underlying data. By being able to interpret the data in these visual forms, it is possible to gain valuable insights into patterns and relationships that might not be immediately apparent from looking at the raw data.

The identity sin θ sec θ = tan θ is true for all values of θ except for the values where cos θ = 0.

To verify the identity sin θ sec θ = tan θ, we need to simplify the left-hand side (LHS) and the right-hand side (RHS) and show that they are equal.

LHS = sin θ sec θ

= sin θ (1/cos θ)

= sin θ/cos θ

= tan θ

RHS = tan θ

Since LHS = RHS, we can conclude that the identity sin θ sec θ = tan θ holds true.

The domain of validity for this identity is all real numbers θ except for the values where cos θ = 0. At those values, the expression sec θ is undefined.

The identity sin θ sec θ = tan θ is verified to be true for all values of θ except for the values where cos θ = 0.

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

The increase in price (8.20%) is less than the interest she would have paid (12 payments of $7125), it seems that postponing her purchase and saving money was a good trade-off for Dorothy.

The APR (Annual Percentage Rate) for Dave's loan can be calculated

using the formula:

APR = ((Total interest + Service charge) / Principal) * 100

In this case, the total interest is $44.90 and the service charge is $6.40.

The principal is $600. Plugging these values into the formula:

APR = (($44.90 + $6.40) / $600) * 100

Simplifying the equation:

APR = ($51.30 / $600) * 100

APR = 8.55%

For Dorothy, if she bought the dishwasher on credit, the total cost would

be $855.00 after making 12 monthly payments of $7125.

However, if she saved $70.00 a month for one year, she would have

$898.80 in deposits plus interest.

When she goes back to the store, the dishwasher now costs $908.88,

which is an increase of 8.20%.

Since the increase in price (8.20%) is less than the interest she would

have paid (12 payments of $7125), it seems that postponing her purchase

We would liken the given scenario to distance speed and time relationship. The formula for determining average speed is

Total Distance/ total time

Since the distance between Earth and Mars is 108 million miles(108 × 10^6) the trip takes 245 days, then on average, the number of miles that the astronauts would travel each day would be

108 × 10^6/245 = 440816 miles per day

Answer:

  13√731 ≈ 351.48 cm²

Step-by-step explanation:

When given three sides of a triangle, there are a number of ways that the area may be calculated. Perhaps the most straightforward is the use of Heron's formula.

Where s is the semi-perimeter, the area is given by ...

  A = √(s(s -a)(s -b)(s -c)) . . . . . . . . s = (a+b+c)/2

Here, the value of s is ...

  s = (30 +30 +26)/2 = 43

  A = √(43(13)(13)(17)) = 13√(43·17)

  A = 13√731 ≈ 351.48 . . . . . square centimeters

_____

Additional comments

This triangle is isosceles, so the altitude can be found from the Pythagorean theorem:

  h² +13² = 30²

  h = √(900 -169) = √731

Then the area is ...

  A = (1/2)bh = (1/2)(26 cm)(√731 cm) = 13√731 cm²

__

You can also find one of the angles using the Law of Cosines, then find the area from ...

  Area = (1/2)a·b·sin(C) . . . . . . for any two sides a, b, and enclosed angle C

__

Ultimately, all of these methods are equivalent to Heron's formula.

The details of the question indicates relationship equations from which the number of erasers Edwin had at first, is 45 erasers

An equation is a statement of equivalence between expressions.

The number of erasers they each finally had = 360/3 = 120

The number of erasers Dennis had before Fred lost sum erasers to him, x is therefore;

1.60·x = 120

x = 120/1.6 = 75

The number of erasers Fred lost to Dennis = 120 - 75 = 45

Let a, represent the number of erasers Dennis initially had, and let b, represent the number of erasers, Edwin initially had, and let c represent the number of erasers Fred had, we get;

a + b + c = 360

The number of erasers Edwin won from Dennis = 2·b

The number of erasers Dennis then had = a - 2·b

The number of derasers Fred won from Dennis = 0.1·c

The number of erasers Fred then had = 1.1·c

a - 2·b = 75

1.1·c - 45 = 120

c = (120 + 45)/1.1 = 150

a - 2·b = 75...(1)

a + b + 150 = 360

a + b = 360 - 150 = 210

a + b = 210...(2)

a - 2·b = 75

Subtract equation (1) from equation (2), we get;

b - (-2·b) = 210 - 75 = 135

3·b = 135

b = 135/3 = 45

a + 45 + 150 = 360

a = 360 - (45 + 150) = 165

a = 165

The probability that the two students are of the Opposite gender is 0.508

It is given that there are a total number of 32 students of which 18 are girls and 14 are boys. Let us assume that the Probability of getting a girl is indicated by P(G) and the probability of getting a boy is indicated by P(B).

Probability of getting a Girl and a boy = P(GB)

Probability of getting a boy and a girl = P(BG)

Sampling will be done without replacement

Now, the probability of getting two students of the opposite gender can be determined by:

=> P(GB) + P(BG)

First, we will find P(GB)

=> P(GB) = P(G) + P(B)

=> P(GB) = (18/32) + (14/31)

=> P(GB) = 0.2540

Similarly, for P(BG)

=> P(BG) = P(B) + P(G)

=> P(BG) = (18/32) + (14/31)

=> P(BG) = 0.2540

we will find out the probability of selecting two students by

=> P(GB) + P(BG)

=> 0.2540 + 0.2540

=> 0.508

Hence, the probability of selecting two students at random of the opposite gender will be 0.508

(a) The inequality equations for the given shop are x + y ≤ 50 denotes the number of wakeboards and surfboards combined (no more than 50) and 150x + 100y ≥ 3000 denotes the earnings of the shop.

An inequality equation is the mathematical representation of two expressions comparatively related to each other. I.e., In the inequality equation, unlike the normal equation, the expressions are not always equal but they are either less or more.

Given,

The price for a surfboard is $150 and the price for a wakeboard is $100.

Consider the number of surfboards = x and the number of wakeboards = y.

The shop owner is only permitted to produce a total of 50 wakeboards and surfboards.

So, we can write this as

x + y ≤ 50....(1)

He wants to make at least $3000 a month. So, we can write this as

150x + 100y ≥ 3000....(2)

Thus, the two inequality equations form a system of inequalities.

When they graphed, we get the possible combinations of the number of surfboards and the number of wakeboards.

The graph for the obtained inequalities is shown in the figure below.

From the graph, we can choose any of the combinations that are in the intersection of both graphs of the system.

Here, take (10, 40) and (30, 20) coordinates that are considered from the intersecting area of both inequalities.

Therefore, the possible combinations of surfboards and wakeboards that he need to sell to make at least $3000 are

10 surfboards + 40 wakeboards

or

30 surfboards + 20 wakeboards

(There are some more combinations we can get from the graph).

(b) The two possible combinations of wakeboard and surfboard are:

10 surfboards and 40 wakeboards i.e., 10 + 40 ≤ 50 and

30 surfboards and 20 wakeboards i.e., 30 + 20 ≤ 50

The statement concerning the binomial distribution that is correct is: "Its CDF shows the probability of each value of X."A binomial distribution is a probability distribution that describes the probability of k successes in n independent Bernoulli trials, where p is the probability of success in any one trial. The probability density function (PDF) of the binomial distribution is given by: P (X = k) = (n k)pk(1−p)n−k, Where X is the random variable representing the number of successes, p is the probability of success, and n is the number of trials. The cumulative distribution function (CDF) of the binomial distribution, on the other hand, gives the probability of obtaining a value less than or equal to x. Therefore, the correct statement concerning the binomial distribution is: "Its CDF shows the probability of each value of X. "Option A, "Its CDF is skewed right when π < 0.50," is incorrect because the skewness of the binomial distribution depends on both n and p, not just p. Option C, "Its PDF covers all integer values of X from 0 to n," is also incorrect because the binomial distribution only covers integer values of X from 0 to n, not necessarily all of them. Finally, option D, "Its PDF is the same as its CDF when π = 0.50," is incorrect because the PDF and CDF of the binomial distribution are different for any value of p, not just when p = 0.50.
