Answer:

C. y = -x + 3

Step-by-step explanation:

y = x + 2

Find perpendicular slope (opposite reciprocal):

x/1 --> -1/x or -x

Convert to point-slope form:

y - (-1) = -1 (x - 4)

y + 1 = -1x + 4

y = -x + 3

The graph shows equivalent Leah plots a point to show a fourth equivalent ratio. If the y-value of Leah’s point is 36, what is t

denis23 [38]

All you have to do is find the slope of the graph.

1) Pick 2 points: (8,9) and (16,18) for example
2) Use the slope formula (y2-y1)/(x2-x1)
3) Once you know the slope, you know how much the graph will rise for each x-unit. Find the x distance between 24 and the new point (36), and use can calculate how high the y value should be

Does that help?

The following estimated regression equation was developed for a model involving two independent variables.

Alik [6]

Answer:

(a): y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second

(b): Yes

Step-by-step explanation:

Given

$\wedge y = 40.7 + 8.63x_1 +2.71x_1$

$\wedge y = 42.0 + 9.01x_1$

Solving (a): An interpretation of x1 coefficient

We have the coefficients of x1 to be 8.63 and 9.01

Literally, the coefficient represents the average change of y-variable per unit increase of the dependent variable

Since the coefficients of x1 in both equations are positive, then that represents an increment on the y variable.

So, the interpretation is:

y increases on average by 8.63/unit of x1 in the first equation and increases on average by 9.01/unit of x1 in the second

Solving (b): Multicollinearity

This could be the cause because x1 and x2 are related and as a result, x2 could take a part of the coefficient of x2

What is the surface area of the right cone below?

Snowcat [4.5K]

Answer:

B. 54π units ²

Step-by-step explanation:

solution:

given,

Radius (r) = 3

(l) = 15

we know that,

T.S.A. of cone = πr( r + l )

= π × 3(3 + 15)

= π × 3 × 18

= π × 54

= 54π units ²
