Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa. In statistics, a perfect negative correlation is represented by the value -1, a 0 indicates no correlation; and a +1 indicates a perfect positive correlation.

indica que as duas variáveis movem-se em direções opostas, e que a relação também fica mais forte quanto mais próxima de menos 1 a correlção ficar. Duas variáveis que estão perfeitamente correlacionadas positivamente (r=1) movem-se essencialmente em perfeita proporção na mesma direção, enquanto dois conjuntos que estão perfeitamente correlacionados negativamente movem-se em perfeita proporção em direções opostas.

Two resistors have the values as given, R1 = 110Ω, and R2 = 560Ω. Find the equivalent resistance when the two resistors are in s
Softa [21]

Answer: SERIES = 670  Ω

PARALLEL = 91.94 Ω

Step-by-step explanation:

Hi, resistors in series obey the following equation :

R1+ R2 = RT

RT is the equivalent resistance. We have the value of both resistances, so we apply the ecuation:

R1 = 110Ω, and R2 = 560Ω

110Ω+ 560Ω = 670 Ω

When resistors are in parallel, resistors obey the following equation:

1/R1 + 1/R2= 1/RT

so, in our case:

1/ 110Ω +1/560Ω = 1/rt

0.01087Ω = 1/RT

RT= 1/0.01087 Ω= 91.94 Ω

(2a+b) (a-b) + (2a-b) (a+b)
yanalaym [24]

Answer: 4a^2-2b^2 (I think this is right)

Step-by-step explanation:

Using the order of operations I started by multiplying both of the sides separately. The left side of the equation becomes 2a^2-b^2-ab while the right becomes 2a^2-b^2+ab. Then I put the sides together to add them and after combining like terms it becomes 4a^2-2b^2.

Jug A holds 1800ml Jug B hold 3/10 more. How much does jug B hold?​
olga55 [171]

Answer:

Jug B can hold 2340 ml.

Step-by-step explanation:

Given

The amount in Jug A = 1800ml

To determine

How much does jug B hold?​

Give that the Jug B holds 3/10 more, i.e.

\frac{3}{10}\times \:1800=540

Thus,

The total amount in Jug B = 540+1800

                                           = 2340 ml

Therefore, Jug B can hold 2340 ml.
