(1)
we are given
we can find for y
multiply both sides by 6
we can see that y is directly proportional to x
so, option-D........Answer
(2)
y varies inversely with x
so, we can write it as
now, we are given
y=5 when x=2.5
so, we can plug it here
and then we can solve for k
now, we can plug back
we can plug x=20
.............Answer
(3)
we are given
The current, I, in a circuit varies inversely with the resistance, R
so, we can write it as
we have R=12 when I=3
so, we can plug it
now, we can solve for k
now, we can plug back
we can plug R=6

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
Step-by-step explanation:
A. 4(a + 1) = 2
= 4a + 4 = 2
= 4a = 2-4 = - 2
= a = - 2/ 4 = - 1/2
B. 3 - 9x = - 6-8x
3 + 6 = - 8x +9x
9 = x
C. 12x - 3 = 14x - 35
- 3 + 35 = 14x - 12x
32 = 2x
32 / 2 = x
16 = x
Answer:
gcf, hcf, lcd (308; 420) = 28 = 2^2 × 7: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.
