Complete question :

A study was done to investigate the population of bald eagle breeding pairs over time. The correlating regression model is shown

below, wiere x represents the number of years after 1986, and y represents the number of bald eagle breeding pairs. Interpret the y-

intercept

y = 1.772 +334x

Answer:

B. There were approximately 1.772 eagle breeding pairs in 1986

Step-by-step explanation:

Given the regression equation : y = 1.772 +334x

Recall the general form of a linear regression equation :

y = mx + c

y = predicted variable ; x = predictor Variable ; c = intercept ; m = slope

x = number of years after 1986 ; y = number of bald eagle pairs.

The intercept is a constant value at time t = 0

For x to be 0, on a graph, this this the value on the y axis where the regression line crosses the y - axis. That is in 1986; the number of y when in 1986 when x = 0 is 1.772

Carlita has 2 1/2 pounds of turkey, the cherries are 1/4 equal to the turkey, and the chocolate drips are .35 equal to the cherr
denis23 [38]

Answer: There are 3.5 ounces of chocolate drips that Carlita need.

Step-by-step explanation:

Since we have given that

Number of pounds of turkey = 2\dfrac{1}{2}=\dfrac{5}{2}

Since the cherries are \dfrac{1}{4} equal to the turkey.

So, it becomes,

Number of pounds of cherries is given by

\dfrac{1}{4}\times \dfrac{5}{2}\\\\=\dfrac{5}{8}\\\\=0.625

Since the chocolate drips are 0.35 equal to the cherries.

So, the number of pounds of chocolate drips is given by

0.625\times 0.35\\\\=0.21875\ lb

Since 1 pound = 16 ounces.

So, Number of ounces of chocolate drips would be

0.21875\times 16\\\\=3.5\ ounces

Hence, there are 3.5 ounces of chocolate drips that Carlita need.

Please help<br><br> I need help creating a table of value for this equation
Fed [463]

Answer:

Create the table and choose a set of x values. Substitute each x value (left side column) into the equation. Evaluate the equation (middle column) to arrive at the y value. An Optional step, if you want, you can omit the middle column from your table, since the table of values is really just the x and y pairs.

Step-by-step explanation:

Specify a name for the function.

Specify a name and data type for each input parameter.

Specify the routine attributes.

Specify the RETURNS TABLE keyword.

Specify the BEGIN ATOMIC keyword to introduce the function-body.

Specify the function body.
