Bas_tet [7]3 years ago
4 0

Step-by-step explanation:

a.) the given term can be written as

=

\sqrt{3}  \times  \sqrt{3 \times 2}

=

\sqrt{3 \times 3 \times 2}

=

3 \sqrt{2}

hence the given term is

3 \sqrt{2}

where b = 3

b.)

=

\sqrt{8}  \times  \sqrt{18}

=

\sqrt{2 \times 2 \times 2}  \times  \sqrt{2 \times 3 \times 3}

=

\sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3}

=

12

hence the given term is 12

Find the perimeter of the following shape, rounded to the nearest tenth:
OLga [1]

Answer: the perimeter of the shape is 19.1

Step-by-step explanation:

To determine the length of each side of the quadrilateral, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side

For line AD,

AD² = 2² + 4² = 4 + 16 = 20

AD = √20 = 4.47

For line AB,

AB² = 1² + 5² = 1 + 25 = 26

AB = √26 = 5.1

For line BC,

BC² = 2² + 4² = 4 + 16 = 20

BC = √20 = 4.47

For line CD,

CD² = 1² + 5² = 1 + 25 = 26

CD = √26 = 5.1

The perimeter of a plane figure is the distance around the figure. Therefore

Perimeter = AB + AB + BC + CD

Perimeter = 4.47 + 5.1 + 4.47 + 5.1 =

19.1

Which of the following is used to determine the significance of predictions made by a best fitting linear equation?A. correlatio
timurjin [86]

Answer:

D. method of least squares

Step-by-step explanation:

The Least Squares Method (LSM) is a mathematical method used to solve various problems, based on minimizing the sum of the squared deviations of some functions from the desired variables. It can be used to “solve”                  over-determined systems of equations (when the number of equations exceeds the number of unknowns), to find a solution in the case of ordinary (not redefined) linear or nonlinear systems of equations, to approximate the point values ​​of a function. OLS is one of the basic regression analysis methods for estimating the unknown parameters of regression models from sample data.

Correlation analysis is a statistical method used to assess the strength of the relationship between two quantitative variables. A high correlation means that two or more variables have a strong relationship with each other, while a weak correlation means that the variables are hardly related. In other words, it is a process of studying the strength of this relationship with available statistics.

Analysis of Variance (or ANOVA) is a collection of statistical models used to analyze group averages and related processes (such as intra- and inter-group variation) in statistical science. When using Variance Analysis, the observed variance of a specified variable is divided into the variance component that can be based on different sources of change. In its simplest form, "Analysis of Variance" is a inferential statistical test to test whether the averages of several groups are equal or not, and this test generalizes the t-test test for two-groups to multiple-groups. If multiple two-sample-t-tests are desired for multivariate analysis, it is clear that this results in increased probability of type I error. Therefore, the variance analysis would be more useful to compare the statistical significance of three or more means (for groups or for variables) with the test.

Regression analysis is an analysis method used to measure the relationship between two or more variables. If analysis is performed using a single variable, it is called univariate regression, and if more than one variable is used, it is called multivariate regression analysis. With the regression analysis, the existence of the relationship between the variables, if there is a relationship between the strength of the information can be obtained. The logic here is that the variable to the left of the equation is affected by the variables to the right. The variables on the right are not affected by other variables. Not being influenced here means that when we put these variables into a linear equation in mathematical sense, it has an effect. Multiple linearity, sequential dependency problems are not meant.

PLEASE HELP GIVING 20 PTS!!!!!! For circle H, JN = 3, NK = x, LN = 2, and NM = 6. Solve for x. PLEASE HEEELLLLPPPPPPP!!!!!!!
Marina CMI [18]

Answer:

x=9

Step-by-step explanation:

when two chords intersects each other, then the product of their segments is equal.

JNxNK = LN x NM

3 *x = 2 * 6

x = (3*6)/2 = 18/2 = 9
