=25x2+y2+z2−10xy−2yz+10xz
It can be simplified to 200 divided by 2.
Answer:
See explaination
Step-by-step explanation:
See attachment for diagram
The r value is 0.373 (low). This implies a weak correlation between the dependent and independent variables for this sample.
The overall p- value for the regression model is 0.0017. This implies that at least one of the two independent variables (x1 or x2) in the model is significant predictor of the dependent variable y.
p- values for the both "Fact" and "Star" are < 0.05. This means both the independent variables are significant predictors of the "Rating" at 95% confidence level. The variable "Fact" is significant at 99% level of confidence also. This means the rating viewers award to a movie depends upon both the storyline (fact or Fiction) and the presence or absence of stars.
Expected rating for a fact based movie with no stars = 1.7991(1) + 1.2586(0) + 12.5685 = 14.37
Expected rating for a fiction based movie with a star = 1.7991(0) + 1.2586(1) + 12.5685 = 13.83
So, one may expect a fact based movie without any stars to get better ratings than a fiction based movie with one star.
X = 17/3 :) :)
add 4 to both sides
then divide both sides by 3
Answer:
B . 
Step-by-step explanation:
<u>Arithmetic sequence</u>:-
Step1:
Given sequence is 
Above sequence taking numerator terms
3,6,9,12,15 are in arithmetic progression
First term a= 3 and difference d = 3
now n t h term of given sequence is

now substitute a =3 and d=3

Step2:-
Above sequence taking denominator
4,5,6,7,8...
here a=4 and d=1



Final answer is the general term of given sequence is
