Answer:
The lengths of the sides can be 10, 30 and 31. This would be a scalene triangle.
Step-by-step explanation:
In order to determine if it can create a triangle, we simple need to make sure that the value of one side is not greater than the other two added together. In this case, 10+30 > 31, which means it can be a triangle.
A triangle with no matching sides is called a scalene triangle. Therefore, we know it is a scalene triangle.
Answer:Its O.x^2-4x-21
Step-by-step explanation:
(x-7)(x+3)we multiplie one value with anothet in different brackets and we get x^2+3x-7x-21,add same constant with x and u get .O
Answer:
Last option (1/2)^3 = .125
Step-by-step explanation:
1/2 (1.035)^5 =0.579637
(2/3)^2 = 4/9 = .4444
.2^2/.3^2 = 0.04/0.09 = .44444
(1/2)^3 = 1/8 = .125
So we can clearly see the last one as the answer
9514 1404 393
Answer:
c. Their correlations are the same, but the equations are different
Step-by-step explanation:
The formula for the correlation coefficient of two variables is symmetrical: it is unchanged when the variables are interchanged. This means Juan and Belle will both calculate the same correlation coefficient.
The formulas for the linear regression equation depend on the choice of dependent and independent variable. Since Juan and Belle have made opposite choices for those, their equations will be different. (Each function will be the inverse of the other.)
The appropriate description is found in choice C.
