The linear equation is Y = -55643.61069X + 112841371.95165, and

value for year 2000 is  $15,54,150.6.

When modelling the relationship between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method (also known as dependent and independent variables). Simple linear regression is used when there is only one explanatory variable, and multiple linear regression is used when there are numerous variables. As opposed to multivariate linear regression, which predicts numerous correlated dependent variables as opposed to a single scalar variable, this phrase is more specific.

Given

X(year)          2008           2012         2013         2014            2015           2019

Mean of X is Mx 2013.5

Mean of Y is My 802961.8333

X - Mx      Y - My     (X - Mx)²  (X - Mx)(Y - My)

-5.5   560850.1667  30.25  -3084675.917

-1.5      -693238.8333         2.25  1039858.25

0.5       151050.1667         0.25  75525.0833

1.5      65938.1667         2.25  98907.25

5.5        -302761.8333       30.25  -1665190.083

                                  SS: 65.5     SP: -3644656.5

equation is y = mx + c

m = SP/SS = -3644656.5/65.5 = -55643.61069

c = My - mMx = 802961.83 - (-55643.61 x 2013.5) = 112841371.95165

Y = -55643.61069X + 112841371.95165

and value for year 2000 is

Y = -55643.61069X + 112841371.95165

Y = $15,54,150.6

Hence the equation is  Y = -55643.61069X + 112841371.95165 and amount for year 2000 is  $15,54,150.6.

Step-by-step explanation:

Let's first figure out an expression for the sum of 3 consecutive integers

If [tex]n[/tex]  is the smallest of the 3 consecutive integers, then the next consecutive integer would be [tex]n + 1[/tex] and the next one after that, [tex]n + 2[/tex]

The sum of these would be

[tex]n + (n +1) + (n +3) = 3n + 3[/tex]

The next step is to find out many integers there are between 1 and 2019(since the question says less than 2020) that can be written as the sum of 3 consecutive integers

We get the following inequality:

[tex]3n + 3 < 2020[/tex]

[tex]3n = 2017[/tex]

[tex]n = 2017/3 = 672 \textrm{ (omit fractional part)}[/tex]  

So there are 672 integers that can be expressed the sum of 3 consecutive integers

Since there are a total of 2019 integers between 1 and 2019, subtracting 672 from 2019 will give us the complement i.e. The  number of positive numbers less than 2020, which cannot be written as the sum of three consecutive positive numbers.

Answer:

[tex]2019 - 672 = \boxed{1347}[/tex]

The number of cherries that Sam, Charlie, and Fred have will be 40, 80, and 60, respectively.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A basket containing 180 cherries is split amount 3 different people. Charlie receives twice the amount that Sam receives, and Fred receives 20 more than Sam.

Let the number of cherries that Sam has be 'x'. Then the equation is given as,

x + 2x + x + 20 = 180

Simplify the equation, then we have

x + 2x + x + 20 = 180

4x = 160

x = 40

Then the number of cherries Charlie has is given as,

2x = 2(40)

2x = 80

Then the number of cherries Fred has is given as,

x + 20 = 40 + 20

x + 20 = 60

The number of cherries that Sam, Charlie, and Fred have will be 40, 80, and 60, respectively.

A sample statistic is a numerical measure of a sample size, and it can vary from sample to sample.

In order to calculate a sample statistic, one must first select a sample. This sample is the group of data points that will be used to calculate the statistic. Once the sample is selected, the data values must be measured and recorded. After that, the data must be organized in whatever way is necessary to perform the calculation. Finally, the calculation can be completed with the appropriate formulas or algorithms. This process must be repeated for each sample statistic that needs to be calculated. Sample statistics can vary from sample to sample because different samples have different values, and the calculation of the statistic will be different depending on the values of the sample.

The inequality that represents the case where Donna has equal or more money saved than Jason is:

$600 + $90*m ≤ $300 + $120*m

We know that Jason has $600 on his bank, and he saves $90 per month, then the amount that he has after m months is:

J(m) = $600 + $90*m

Donna has $300 in her bank and she saves $120 each month, so after m months, she has:

D(m) = $300 + $120*m

Now we can write the inequality:

J(m) ≤ D(m)

Replacing the actual equations we will get:

The number .05 is the significance level which indicates the probability of obtaining a result as extreme as the observed one.

The number .05 represents the significance level in the t-test. The significance level is the probability of obtaining a result as extreme as the observed one, given that the null hypothesis is true. In this case, the t-test is measuring the difference between two means and the null hypothesis is that there is no difference between them. The t-value is the test statistic which measures the difference between the groups and the degrees of freedom is the number of observations minus one. The p-value is the probability of obtaining a result as extreme as the observed one, given that the null hypothesis is true. If the p-value is less than .05, this indicates that the result is statistically significant, meaning that the null hypothesis can be rejected and the alternative hypothesis is accepted.

The length of A'C' is 5 units.

A reflection of a function is just the image of the curve with respect to either x-axis or y-axis. This occurs whenever we see the multiplication of a minus sign happening somewhere in the function. Here,

y = - f(x) is the reflection of y = f(x) with respect to the x-axis.

y = f(-x) is the reflection of y = f(x) with resepct to the y-axis.

Here, note that when the function is reflected.

with respect to the x-axis, only the signs of the y-coordinates are changed and there is no change in x-coordinates.

with respect to the y-axis, only the signs of the x-coordinates are changed and there is no change in y-coordinates.

Reflections are considered isometries because they keep the distances constant.

The triangle's form or size will not change if it is reflected. The reflected image would therefore be "congruent" with the actual object.

Assume that the CAT symbol is reflected across the y axis.

The point (x,y-reflection ) across the y-axis is determined by the point (-x,y).

The y-coordinate of a point that is reflected across the y-axis remains constant, but the x-coordinate changes to its opposite (the sign of the x-coordinate will be changed).

We are given that

C(0, 0)   →  C'(0, 0)

A(-2, 1)  →  A'(2, 1)

T(-1, 4)  →  T(1, 4)

length of Side AT = √10 units

length of Side TC = √17 units

length of Side AC = √5 units

Reflections are referred to as isometries because they maintain distances.

Therefore, if CAT reflected crosses the y-axis. The distances are preserved by "C'A'T." Each preimage segment would have a length equal to its corresponding side in the image.

Thus, the length of A'C' is 5 units.
