A certain gecko measured 3.5 inches as a hatchling, and then grows at a steady rate of 1.2 inches per month for the first 12 mon

gregori [183]

Answer:

21.1 inches

Step-by-step explanation:

The gecko is 3.5 inches to start with.

If it grows at a rate of 1.2 inches per month for the first 12 months, after 12 months the gecko will be 14.4 inches larger. (Because 12 times 1.2 is 14.4)

So, after 12 months the gecko will be 17.9 inches.

Since the gecko grows at 0.4 inches per month for the next 16 months, and the gecko has grown for 20 months, all we need to do is subtract 12 from 20 (since we already calculated how long it will be after 12 months) and multiply that by 0.4.

Since 20 - 12 is 8, we just multiply 8 by 0.4 to get 3.2. We now add 3.2 to 17.9 to get 21.1 inches.

Hope this helps!

Use the value of the linear correlation coefficient to calculate the coefficient of determination. What does this tell you about

LenKa [72]

Answer:

Coefficient of determination = 0.149769

Step-by-step explanation:

We are given the following in the question:

Coefficient of correlation, r = -0.387

We have to find the coefficient of determination.

Coefficient of determination =

$r^2 = (-0.387)^2 = 0.149769 = 14.98\%$

Coefficient of determination:

It tells us about the variation explained in the model.
This correlation of determination tells that 14.98% of the variation is explained in the model that is we can say that the independent variable explains 14.98% changes or prediction in the dependent variable.
It ranges from 0 to 1 and a correlation of determination of 1 means that the dependent variable is 100% predicted by the independent variable.
Correlation of determination of 0 means that the dependent variable cannot be predicted by the independent variable.
