Answer: X= 2
Step-by-step explanation:
Based off of the on the longer leg of the triangle we can assume this is a 30, 60, 90 right triangle. In a 30, 60, 90 triangle, the hypotenuse is 2X the shorter leg. So to find x we can set up this equation.
Answer:
The correct option is (A).
Step-by-step explanation:
The multiple linear regression equation is given by, , where <em>α</em> = constant and <em>β</em>
= slope coefficients of regression line.
To test if there is a important relationship amid <em>X</em> and <em>Y</em>, we use the <em>t</em>-statistic test.
The <em>t</em>-statistic for regression coefficient analysis is given by,
The regression equation for test scores dependent upon the two explanatory variables, the student-teacher ratio and the percent of English learners is:
A <em>t</em>-test for the significance of the regression coefficient of variable student-teacher ratio (STR) is conducted.
The test statistic is found to be, <em>t</em> = 2.56.
The regression coefficient of variable STR is, 1.10.
Compute the standard error of the regression coefficient as follows:
The standard error of the regression coefficient is 0.43.
Thus, the correct option is (A).
