Answer:
It is not reasonable to use the line of best fit to make predictions from the data.

Explanation:

A correlation coefficient of r = 0.15 means that the goodness of fit for the data from linear regression analysis is
r² = 0.15² = 0.0225.

When r²=1, it means that correlation between the dependent and independent variable is perfect, and the dependent variable can be predicted reliably.

When r²=0, it means that there is absolutely no correlation between the dependent and independent variable.

When r²>0.9, it means that reasonable correlation exists between the dependent and independent variable.

A value of r²=0.0225 is extremely low, therefore it is not reasonable to use the line of best fit to make predictions.

Answer:

no

Step-by-step explanation:

  • It is not reasonable to use the line of best fit to make predictions.
  • The correlation coefficient for the data is close to zero.
  • The correlation coefficient measures how well a line fits a set of data.
  • The correlation coefficient suggests that the relationship between the two variables is weak.

darren has 3/4 of a gallon of soil.he needs to plant 5 small plants.if he splits the soil evenly between the plants.how much soi
nika2105 [10]

Number of plants = 5

Amount of soil present for 5 plants = 3/4 gallons

Now here we have to find how much soil will each plant get.

So we have to apply unitary method here to find how much would each plant get the share of soil.

Soil required by 5 plants = 3/4 gallons

Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons

Answer: Each plant will get 3/20 gallons of soil.

Write the function that shows a translation of f(x) two units to the left.
Galina-37 [17]

Answer:

Step-by-step explanation:

Suppose the base formula is y = x^2

You want to go two units left.

basically that is y = (x + 2)^2 just the opposite of what you might think it should be.

Where does the base function have a minimum? It's minimum is as x = 0 and y = 0

Where does y = (x + 2)^2 have it's minimum?

(-2,0)

conclusion. The base function has moved 2 units to the left.
