4 0

Answer:

(3x - 5 = -x + 3) x = 2

Step-by-step explanation:

3x - 5 = -x + 3

3x = -x + (3 +5)

3x=-x + 8

(3x + x ) = 8

4x = 8

Melanie began studying a sample of the chemical element einsteinium-253 which naturally loses its mass over time. The relationsh
mario62 [17]

Answer:

The chemical element loses 4% of its weight everyday

Step-by-step explanation:

Here, we are interested in knowing the percentage weight loss of the chemical each day.

The key to answering this is looking at the expression inside the bracket.

We can express M(t) = 169•(0.96)^t as

M(t) = 169•(1-0.04)^t

So what this means is that we need to find the percentage value corresponding to 0.04 since it is a constant term here

Mathematically, 0.04 is same as 4/100, so we can clearly say that the constant percentage loss is 4%

6 Using data from 1988 for houses sold in Andover, Massachusetts, from Kiel and McClain (1995),
Nimfa-mama [501]

The study of explanatory or independent differences based on the dependent variable is a simple statistical method. The correlation between two variables is researched in which only the explanatory variable of them would be present, and the further discussion can be defined as follows:

For point (i):

  • The log(distances) seem to be optimistic, and their valuation is 0.312, which also means that the cost of a house will rise even as the distance increases.
  • In this, the certainly is what everybody expects the better the house from the sewage treatment is from a hygienic viewpoint.

For point (ii):

  • In this regard, we cannot use straightforward regression, even as non-biased price estimation might not even be provided.
  • The price-distance relationship here is not so much linear.

For point (iii):

  • Several factors influence the house's price, the biggest contributor is house length, market nearness or public areas, number of rooms, etc.
  • Thus the only influence is not the mere distance from the incinerator. It's one of the factors affecting housing pricing.
  • The proximity of markets and places can be connected to the distance from the crematorium.
  • However, factors such as house size and the number of stories aren't related to the distance from the incineration plant.

there are 270 at Colfax Middle School, where the ratio of boys to girls is 5:4. there are 180 students at Winthrop Middle School
ruslelena [56]

Colfax:

Add the ratio numbers together:

5 + 4 = 9

Divide total students by that:

270 / 9 = 30

Multiply each ratio by 30:

Boys = 30 *5 = 150

Girls = 30 * 4 = 120


Do the same for Winthrop:

4 +5 = 9

180 /9 = 20

Boys = 20 * 4 = 80

Girls = 20 * 5 = 100


Total students = 270 + 180 = 450

Total Girls = 120 + 100 = 220


Fraction that are girls = 220 / 450 which reduces to 22/45
