Answer:
Yeah same here
Step-by-step explanation:
1- the answer is b and d 2- the answer is a and b 3- the answer is b
For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
The area of a square is expressed as:
Area = s^2
We are given the area of both windows. We will use this value for the calculations. We set s as the side of the larger window and a for the smaller window.
Total area = Area larger + area smaller
1025 = s^2 + a^2
Since it was said that the side of the larger window, s is 5 in longer than the side of the smaller window, a (s = 5+a) then:
<span>1025 = s^2 + a^2
</span>1025 = (5+a)^2 + a^2
simplifying we obtain,
a = 20 inches
Answer:
0.451751 is the proportion of variability of Gini Coefficient explained by our least squares lines
Step-by-step explanation:
Given
To predict: Gini by year
Required
Interpret the R squared
In statistics, r squared measures the extent to which the variance of one variable explains the variance of the other variable.
In this question, the variable to predict is Gini:
From the list of options, (c) is correct
