Answer:I don't know if you're asking for equation or not cause you didn't mention the question so I'm just gonna write down the equation.
y=4.2x+3.4
Use this formula➡️y=mx+b
m is slope, b is y-intercept , x and y are the points like (0, 3.4)
You said it's the y-intercept but it's not. it's just a point on the graph
Step-by-step explanation:
Well the remainder more possible dividing by six would be 9.3 I hope i helped.
Answer:
a) The variable of the study is: milligrams of nitrogen per liter of water.
This is the amount that needs to be measured and analyzed to reach conclusions in the study.
b) The variable is quantitative. The quantitative variables are those that represent quantities. This variables can be measured on a continuous or discrete scale. Then, all the variables that you can measure or count are quantitative variables(height of trees, number of passengers per car, wind speed, milligrams of nitrogen per liter, etc). On the other hand, qualitative variables are those that can’ t be measured, and they represent attributes, like apple colors (red, green), size of trousers (small, medium, large) and so on.
c) The population under study is the milligrams of nitrogen per liter of water that are in the entire lake. You can estimate the parameters of the population by taking samples (In the example, 28 samples are taken).
Well if you have 48 pics of flowers and 36 pictures of scenery and you want an equal amount of pictures of the scenery, you want to start out by just seeing what number divides evenly into both, in this case, it is four.
Speed= distance /time
distnace=170 miles
t=2 hours + 45 minutes *(1 hora / 60 minutes=2 hours + 0.75 hours=2.75 hours.
Speed=170 mile / 2.75 hours=61.818...miles/hour≈61.8 miles/hour.
Solution: 61.8 miles/hour.
