A+b+c=6, a=2c, b=a+c using a and b in the first equation gives you:
2c+a+c+c=6 now use a=2c again
2c+2c+c+c=6
6c=6
c=1, since a=2c
a=2, since b=a+c
b=3
So the number is 231.
Answer:
The value of the correlation coefficient would not change.
Step-by-step explanation:
If the relationship between distance of trips and fares in dollars gives a correlation coefficient value of 0.950. This can be interpreted to mean that the relationship between both variables is strong and positive such that an increase in distance leads to corresponding increase in fares of the trip and vice versa. Thus, interchanging the axis upon which the variables are plotted would still tied the same correlation Coefficient value as the correlation coefficient does not depend on the axis upon which the variables are plotted.
Answer:
20/54
Step-by-step explanation:
The answer should be eight
Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
