Answer:
D. Highest increase in the multiple R2.
Step-by-step explanation:
Included variables in a multiple regression model are those variables which have the most effect on the model ; variables which have no effect on the performance of the model ar discarded. Model performance are based on the variables affect the multiple R² value of the model. The R² value is the coefficient of determination which gives the proportion of change in predicted value based on the regression line. Higher R² value means the variable has greater effect in the model performance. Therefore, variables which have the highest increase on the multiple R² value , are included.
Answer:
v= 291 m/s squared
Step-by-step explanation:
v= ?
a=4 m/s squared
u=3 m/s
t=72 secs
v=u+a(t)
v=3 m/s +4 m/s (72 secs)
v=3 m/s + 288 m/s
v= 291 m/s squared
Answer: 9x^2 + 2x - 5
Step-by-step explanation:
6x^2 - 5x + 3 + 3x^2 + 7x -8
Like terms are: (6x^2 and 3x^2), (-5x and 7x), and (3 and -8)
6x^2 + 3x^2 = 9x^2
-5x + 7x = 2x
3 + -8 = -5
9x^2 + 2x - 5 is the simplest answer
Answer:
Approx. 1343 feet
Step-by-step explanation:
Building A is 71 stories at 875 feet tall. Since the two buildings have the same number of feet per floor, we can divide building A's stories to find the height of 1 story, and then multiply by the stories of building B.
Building A
71 ÷ 71 = 1 story
875 ÷ 71 = 12.32 feet
Each story is approximately 12.32 feet tall
Building B
1 story × 109 = 109 stories
12.32 feet × 109 = 1343.31 feet
Rounded to the nearest foot is 1343 feet.
Answer:
G(2) = 2(2) - 8(2) - 10
G(2) = 4-16-10
G(2) = -2
G(5) + 12 = (2(5) - 8(5) - 10) + 12
G(5) + 12 = (10-40-10) + 12
Step-by-step explanation:
G is the function, the number written in brackets in front of it I.e. (5), (2) etc. Is the number you input in the function
