<u>Answer:</u>

The correct answer option is D. 0.857

<u>Step-by-step explanation:</u>

We are given the correlation coefficient, of a data set to be 0.926 and we are to find the coefficient of determination to three decimal places.

To find that, we will use the following formula:

Coefficient of determination = r ^ 2

r ^ 2 = ( 0 . 9 2 6 ) ^ 2 = 0.857

Answer:

D. 0.857

Step-by-step explanation:

The coefficient of determination, R-squared, is simply the square of the  correlation coefficient;

R-squared = r^2

R-squared = 0.926^2

R-squared = 0.857

Therefore, the coefficient of determination is 0.857.

The vertex of this parabola is at (2, -4). When the y-value is -3, the x-value is -3. What is the coefficient of the squared ter
lyudmila [28]

Answer:

The squared term is 1/25

Step-by-step explanation:

The parabola equation in the vertex form is

y = a \times (x - h)^2 + k

where point (h,k) is the vertex and a is the squared term. In this case h = 2 and k = -4. On the other hand, we know that y = -3 and x = -3 are in the parabola. Replacing these values in the formula gives

-3 = a \times (-3 - 2)^2 - 4

Solving for a

-3 + 4 = a \times (-5)^2

1 = a \times 25

a = \frac{1}{25}

Help me answer this thanks
Doss [256]

Answer:

c = 15 meters

Step-by-step explanation:

This is solveable using the Pythagorean Theorem,

let's say a = 9 and b = 12,

a^2 + b^2 = c^2, so

9^2 + 12^2 = 225 then,

sqrt(225) = 15, so c = 15 m
