if someone wants to buy something that costs $750.000 and it’s 35% off, how much does it costs after the discount?

Answer:

First side = 12 units

Second side = 24 units

Third side = 16 units

Step-by-step explanation:

First, we can assign variables for each side of the triangle to make it easier:

A = side 1

B = side 2

C = side 3

The length of the second side of the triangle is twice the length of the first side, so we know that B is twice the length of A. We can represent this in an equation like this:

B = A * 2

The length of the third side is 4 units more than the first side. This tells us that C is going to be 4 more than A:

C = A + 4

And finally, the perimeter of the triangle is 52 units. Since the perimeter is just all the sides added together, we can create this equation:

A + B + C = 52

To start solving for lengths, I'm going to plug in the first two equations we got into the third equation:

A + B + C = 52

A + (A * 2) + (A + 4) = 52

1A + 2A + 1A + 4 = 52

4A + 4 = 52

4A = 48

A = 12

Now that we know what A is, we can solve for the other two variables:

B = A * 2

B = 12 * 2

B = 24

C = A + 4

C = 12 + 4

C = 16

Now we have all three variables, just don't forget what the variables represent (first side, second side, third side).

The term "average" plays a fundamental role in statistics. It refers to a measure of central tendency that summarizes a set of data by representing a typical or representative value.

Calculation for the average of a set of numbers, follow these steps:

Add up all the values in the data set.

Division of the sum by the total number of values.

For example, consider the following data set: 10, 15, 20, 25, 30.

Sum all the values: 10 + 15 + 20 + 25 + 30 = 100.

Divide the sum by the total number of values: 100 / 5 = 20.

In this case, the average of the data set is 20.

The term average provides a concise summary of a data set by representing a typical value. It is calculated by adding up all the values and dividing the sum by the total number of values. The average is a fundamental statistical measure that helps in understanding and analyzing data in various fields such as economics, education, research, and many others.

A 90% confidence interval is 20% to 24.6%.

To calculate the 90% confidence interval for the percentage of people in the town who read newspapers, we can use the formula:

Confidence Interval = Sample Proportion ± (Critical Value * Standard Error)

First, let's calculate the sample proportion:

Sample Proportion = Number of newspaper readers / Sample size

                 = 223 / 1000

                 = 0.223

Next, we need to find the critical value associated with a 90% confidence level.

For a large sample size like this, we can use the Z-score table or a calculator to find the critical value. For a 90% confidence level, the critical value is approximately 1.645.

Now, we can calculate the standard error:

Standard Error = \(\sqrt((Sample Proportion * (1 - Sample Proportion)) / Sample Size)\)

             = sqrt((0.223 * (1 - 0.223)) / 1000)

             ≈ 0.014

Finally, we can calculate the confidence interval:

Confidence Interval = 0.223 ± (1.645 * 0.014)

                   = 0.223 ± 0.023

                   ≈ (0.200, 0.246)

Therefore, the 90% confidence interval for the percentage of people in the town who read newspapers is approximately 20% to 24.6%.

The closest answer from the options provided would be 20% to 23%.

Step-by-step explanation:

The amount she withdrew is 45*4 =180

405 - 4*45=

405 -180 =225

There is 225 in the account

Answer: a) $225

Step-by-step explanation:

405 - 45 (4) = x

405 - 180 = x

225 = x

Answer:

c = 106°

Step-by-step explanation:

The unknown angle and c° form a straight line which is 180°

So, c° + unknown angle = 180°

Remember, the sum of interior angles of a trapezoid is 360°

So, 126° + 108° + 52° + unknown angle = 360°

unknown angle = 360° - 126° + 108° + 52°

unknown angle = 74°

Now, c° + 74° = 180°

c = 180° - 74°

c = 106°

Problem 1

A = 984 ft = height of the tower in real life

B = 328 ft = width of the tower in real life

C = 12 in = height of the scale model

D = unknown = width of the scale model

A/B = C/D

(984 ft)/(328 ft) = (12 inches)/(D inches)

984/328 = 12/D

984D = 328*12

D = 328*12/984

D = 4

=========================================================

Problem 2

A = 4 cm = some distance on the map corresponding to B

B = 20 km = the corresponding real life distance to A

C = unknown = some distance on the map corresponding to D

D = 82 km = real life distance corresponding to C

A/B = C/D

(4 cm)/(20 km) = (C cm)/(82 km)

4/20 = C/82

4*82 = 20C

C = 4*82/20

C = 16.4

If there are 30 skaters competing at the olympic games, then the required number of ways = 24360

The term permutation refers to a mathematical calculation of the number of ways a particular set can be arranged. Put simply, a permutation is a word that describes the number of ways things can be ordered or arranged. With permutations, the order of the arrangement matters.

Given that,

There are 30 skaters competing in the competition.

To find,

The number of ways in which they can win gold, silver, and bronze medal.

So,

We can write,

In distribution of medals(gold, silver, and bronze) we require 3 winners in a particular order, so for this we use Permutations.

According to permutation , number of ways of selecting r things out of ,

n = \(\frac{n!}{(n-r)!}\)

Then, The number of ways in which 18 skaters can win 3 medals,

= \(\frac{30!}{(30-3)!}\)

= \(\frac{30!}{27!}\)

= \(\frac{30*29*28*27!}{27!}\)

= \(30*29*28\)

= 24360

Therefore,

If there are 30 skaters competing at the olympic games, then the required number of ways = 24360

The asset's variance is approximately 0.0358, and its standard deviation is approximately 0.1891.

To calculate the variance and standard deviation of the asset's returns, we'll follow the steps mentioned earlier using the given probability distribution:

⇒ Calculate the expected return (μ):

μ = (0.27 * 0.25) + (0.18 * 0.25+) + (0.10 * 0.30) + (0.04 * 0.20+)

  = 0.0675 + 0.045 + 0.03 + 0.008

  = 0.1505

⇒ Calculate the variance (σ^2):

σ^2 = [(0.27 - μ)^2 * 0.25] + [(0.18 - μ)^2 * 0.25+] + [(0.10 - μ)^2 * 0.30] + [(0.04 - μ)^2 * 0.20+]

Substituting the values and simplifying:

σ^2 = [(0.27 - 0.1505)^2 * 0.25] + [(0.18 - 0.1505)^2 * 0.25+] + [(0.10 - 0.1505)^2 * 0.30] + [(0.04 - 0.1505)^2 * 0.20+]

    = [(0.1195)^2 * 0.25] + [(0.0295)^2 * 0.25+] + [(-0.0505)^2 * 0.30] + [(-0.1105)^2 * 0.20+]

    = 0.017972 + 0.00021617 + 0.0030309025 + 0.01459516

    = 0.0358141325

⇒ Calculate the standard deviation (σ):

σ = √(σ^2)

  = √(0.0358141325)

  ≈ 0.1891

Therefore, the asset's variance is approximately 0.0358 and the standard deviation is approximately 0.1891.

Step-by-step explanation:

No, the presence of an effect does not necessarily imply that error variance will go away.

The presence of an effect does not necessarily imply that error variance will go away. In fact, error variance is an inherent part of any statistical model and represents the amount of variation in the response variable that is not explained by the predictor variables.

Even if a predictor variable has a significant effect on the response variable, there may still be some unexplained variation in the response that is attributable to error variance.

It is important to take into account and control for error variance in any statistical analysis, as it can affect the precision and accuracy of the estimates of the model parameters and can also influence the interpretation of the results.

One way to control for error variance is to use appropriate statistical methods, such as analysis of variance (ANOVA), regression analysis, or other modeling techniques that take into account the variability in the data.

Using the binomial distribution, it is found that the expected score of the game is of 21.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q successes is:

\(E_s(X) = \frac{q}{p}\)

In this problem, a die has a p = 1/6 probability of resulting in a 1, hence the expected number of trials is:

\(E_s(X) = \frac{1}{\frac{1}{6}} = 6\)

In each trial, each outcome from 1 to 6 is equally as likely, hence the expected score of a single trial is given by:

\(E = \frac{1 + 6}{2} = 3.5\)

Then, the expected score of the six trials is:

New Value = 27

Using the formula, we have:

Percentage Change = ((27 - 6) / 6) * 100

Calculating this expression, we find:

Percentage Change ≈ 350.00

Rounding the percentage change to two decimal places, we have:
