Answer:
x=-6,11
Step-by-step explanation:
Break down the problem into these 2 equations.
2x-5=17
-(2x-5)=17
2 Solve the 1st equation: 2x-5=17
x=11
3 Solve the 2nd equation: -(2x-5)=17
x=-6x
4 Collect all solutions.
x=-6,11
Answer:
coefficient of determination
Step-by-step explanation:
The Coefficient of determination, R² which is the squared value of the correlation Coefficient is used to give Tha proportion of variation in the predicted / dependent variable that can be explained by the regression line. The coefficient of determination ranges from 0 to 1. Once the proportion of explained variation is obtained, the proportion of unexplained variation is ( 1 - proportion of explained variation).
Answer:
36
Step-by-step explanation:
By the Fundamental Counting Principle, if there are x ways to choose one thing, y ways to choose another thing, and z ways to choose another thing, then there are x*y*z possible combinations of all of those things.
Here, there are 3 ways to choose a shift, 4 ways to choose a pair of pants, and 3 ways to choose a tie. Therefore, there are 3*4*3 = 36 different outfits that Gerald can make that include one shirt, pair of pants, and tie.
First, since Kim has already read 2 pages you subtract 44-2. Now you only have to divide 42 by 20 which is 2.1 hours. 2.1 hours is the equivalent of 2 hours and 6 minutes.
