Answer:
subtract 9 on both sides.
Step-by-step explanation:
-5m+9=12 --> -5m=7
The measurement of STR is 24 degrees
Answer:
A. True
Step-by-step explanation:
Stepwise regression is a variable-selection method for independent variables.
Stepwise regression helps us to recognize and choose the most handy descriptive variables from a list of several reasonable independent variables.
It entails a series of steps that is drafted to locate the most handy X-variable to incorporate in a regression model. During each step of the course of action or method, each X - variable is estimated by applying a set criterion to determine if it is meant to exist in the model.
The basis for selection can be choosing a variable which satisfies the stipulated criterion or removing a variable that least satisfies the criterion. A typical illustration of such criterion is the t value.
Answer:
arc AB = 12.40°
Step-by-step explanation:
diameter = 7.9 x 2 = 15.8
circumference = 15.8 x 3.14 = 49.612
since the central angle of arc AB is 90 °
90/360 x 49.612 = 12.40
Answer: b, 12
explanation: combine -3/2 * x and u get -3/2x. then isolate the variable by doing the inverse of subtraction on both sides. (add 9 on both sides). then do the inverse of multiplication on both sides. (divide by -3/2 on both sides)
