help pls I don't have enough points to give yall pls

Step-by-step explanation:

you simply have to mark the points in which the x and y coordinates are given take for example "1,4" it took him 4 minutes to read 1 page right? the one is marked as X and the 4 is marked as Y so put a point in which the 1 at X and the 4 at Y meet in the coordinates system. Do so with every coordinates and then draw a line in the direction of all the points

just mark down the coordinates on the plane, like this.

It falls between: The population mean is 13. 8. The population variance is 192. The population's standard deviation is 13.856.

A key measure of dispersion in statistics is population standard deviation. additional reading Statisticians compute variance to determine how various values inside a data collection interact to one another. While calculating the population variance, one may also compute the dispersion in relation to the population means.

The range: 15 - 2 = 13

The population mean is:

Mean = ( 2 + 10 + 15 + 2 + 12 + 13 + 7 + 3 + 8  ) / 9 = 8

The population variance ( S² or Sigma² ):

S ² = 1/9 · ( ( 2 - 8 )² + ( 10- 8 )² + ( 15 - 8 )² + ( 2 - 8 )² + ( 12 - 8 )² + ( 13 - 8 )² + ( 7 - 8 )² + ( 3 - 8 )² + ( 8 - 8 )²  )

S ² = 192

The population standard deviation:

S = √(S²) = √192 = 13.856

I need to deposit $1558.41 to have $2000 in the account in 5 years.

What is compound interest?

The interest charged on a debt or deposit is known as compound interest. It is the idea that we use the most regularly. Compound interest is calculated for a sum based on both the principal and cumulative interest.

    ∴ Compound interest = P(1 + \(\frac{r}{100*12}\))ⁿ  (∵ for monthly interest)

        P = Principal

        r = rate of interest per month

        n = number of months

Given:

r = 5% per month

n = 5 years = 5*12 = 60 months

  CI = P (1+5/(12 * 100))⁶⁰

2000 = P(1.0041)⁶⁰

2000 = P(1.2834)

      P = 1558.41

Therefore, the amount required to deposit is 1558.41 dollars to get 2000 dollars after 5 years with 5 percent interest per month.

Multiply the length by with by height and you will get the volume of the tank which is approximately 105 cubic feet. Once you do that you can multiply be the weight of the milk per cubic foot and you will get the waight of the milk inside the tank which is 6982.5LB.

Answer:

x = 50

Step-by-step explanation:

\( log_{10}(2x) = 2\)

Use the following property.

\( log_{a}(m) = n \\ {a}^{n} = m\)

\( {10}^{2} = 2x \\ 100 = 2x \\ \frac{100}{2} = x \\ 50 = x\)

Therefore, the value of x is 50.

Answer Check

Substitute x = 50 in the equation.

\( log_{10}(2x) = 2 \\ log_{10}(2(50)) = 2 \\ log_{10}(100) = 2 \\ {10}^{2} = 100 \\ 100 = 100\)

The equation is true. Therefore x = 50.

Answer:

apart from using the hoc to predict the college students gpa, some other variables can be used

1. the students intelligent quotient

2. ability to remember

3. study time

4. gym practice

Step-by-step explanation:

1. the students intelligent quotient

gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.

2. ability to remember

the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction

3. study time

gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.

4. gym practice

gpa and gym practice are not related so the slope would be in a downward direction.

when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.

Given:

Data set = \(\{x, 2x, 3x, 4x\}\)

To find:

The absolute mean deviation for the given set.

Solution:

We have,

Data set = \(\{x, 2x, 3x, 4x\}\)

Mean of the data set is

\(Mean=\dfrac{\sum x_i}{n}\)

\(Mean=\dfrac{x+2x+3x+4x}{4}\)

\(Mean=\dfrac{10x}{4}\)

\(Mean=2.5x\)

Now,

The formula for mean absolute deviation (MAD) is

\(MAD=\dfrac{\sum |x_i-\overline x|}{n}\)

\(MAD=\dfrac{|x-2.5x|+|2x-2.5x|+|3x-2.5x|+|4x-2.5x|}{4}\)

\(MAD=\dfrac{|-1.5x|+|-0.5x|+|0.5x|+|1.5x|}{4}\)

\(MAD=\dfrac{1.5x+0.5x+0.5x+1.5x}{4}\)

\(MAD=\dfrac{4x}{4}\)

\(MAD=x\)

Therefore, the mean absolute deviation for the given set of data is x.

Answer: Changing the radius of an object by a given amount has a greater effect on the volume than changing the height by the same amount. The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. If we change the radius by a given amount, say x, the new radius would be r+x. Hence, the new volume would be V' = π(r+x)²h = π(r²+2rx+x²)h = V + 2πrxh + πx²h. We can see that the volume change equals 2πrxh + πx²h. The first term is proportional to both the radius and the height, whereas the second term is proportional to the square of the radius and the height. Assuming that the height change is also x, the new volume would be V'' = πr²(h+x) = V + πr²x. We can see that the volume change is proportional to the radius squared and the change in height. Therefore, changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount.

Using proportions, we can say that 42 models of 100 are needed to model 4200.

Ratio and fractions are the main bases on which proportion is explained. A fraction is written as a/b, while a ratio is represented as a:b, and a proportion states that two ratios are equal. In this case, a and b can be any two integers. The ratio and proportion are important building blocks for understanding the numerous ideas in science and mathematics.

In the question, we are asked for the number of models of 100 we need to model 4200.

The given problem can be shown as a proportion with the ratio of the number of models of 100, to the model.

We know that 1 model of 100 makes a model 100.

We assume that n models of 100 makes a model 4200.

By proportion, we can show that:

n/4200 = 1/100,

or, n = 4200/100,

or, n = 42.

Thus, using proportions, we can say that 42 models of 100 are needed to model 4200.

Answer:

$\(45\)

Step-by-step explanation:

\(30\)% \(\mathrm{of}\) $\(150\)

\(=\frac{30}{100}\times 150\\\)

\(=\) $\(45\)

Answer: 1.To find the mean, we sum up all the scores and divide by the number of scores:

Mean = (5 + 12 + 8 + 14 + 11) / 5 = 50 / 5 = 10

To find the variance, we first find the deviation of each score from the mean:

5 - 10 = -5

12 - 10 = 2

8 - 10 = -2

14 - 10 = 4

11 - 10 = 1

We square each deviation and sum them up:

(-5)^2 + 2^2 + (-2)^2 + 4^2 + 1^2 = 26

Then, we divide by the number of scores to find the variance:

Variance = 26 / 5 = 5.2

Finally, we find the standard deviation by taking the square root of the variance:

Standard deviation = √5.2 = 2.28

2. To construct a simple random sample of size 2, we can choose any two scores from the population. The number of ways to do this is given by the combination formula:

C(5,2) = 5! / (2! * (5 - 2)!) = 10

Therefore, there are 10 simple random samples of size 2 that can be constructed.

3.The mean of the sampling distribution of the sample means is equal to the population mean, which we found to be 10. The variance of the sampling distribution is equal to the population variance divided by the sample size:

Variance of sampling distribution = Variance / Sample size = 5.2 / 2 = 2.6

The standard error of the sampling distribution is the square root of the variance:

Standard error = √2.6 = 1.61

4.The variance of the sampling distribution is 2.6, as we found in part

5. Since this is considered to be data from a simple random sample, we can use the sample mean as a point estimate of the population mean. Therefore, the point estimate of the population mean is 10.

Similarly, we can use the sample variance as a point estimate of the population variance. However, we need to correct for the bias in the sample variance by dividing by (n-1) instead of n:

Point estimate of population variance = Variance * (n / (n-1)) = 5.2 * (5 / 4) = 6.5
