An agricultural scientist collected data to study the relationship between the amount of nitrogen added to a cornfield and the n

umber of
bushels of corn produced. This is the regression line of the data, where y is measured in bushels of corn and x is measured in pounds of
nitrogen.
y = 0.43x + 28.5
What is the meaning of the slope of the regression line?
O A. For every 0.43 pounds of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels.
OB. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 0.43 bushels.
-
OC. For every 1 pound of nitrogen added to the field, the amount of corn yielded increases by 28.5 bushels.
OD. For every 28.5 pounds of nitrogen added to the field, the amount of corn yielded increases by 0.43 bushels.

den301095 [7]

Answer:

  • 12x +9y ≥ 510
  • y ≤ 2x
  • y ≥ 25

Step-by-step explanation:

Phoebe earns 12x for her yard weeding, and Richie earns 9y for his dog walking. They want the sum of these earnings to be at least 510, so the first constraint inequality is ...

  12x +9y ≥ 510

__

Richie plans to walk no more than 2x dogs, since y is the number of dogs he walks, the second constraint is ...

  y ≤ 2x

__

Richie will walk at least 25 dogs, so ...

  y ≥ 25

Fittoniya [83]

The travels you have described are:

                                       (Middle floor) + 8 + 5 - 9 + 7 - 32

                                   =  (middle floor)  + 20 - 41

                                   =  (middle floor)  -  21  brought her to floor #1.

So                                   Middle floor  -  21  =  1

Add 21 to each side:    Middle floor  =  22 

The building has (2 x middle floor)  =  44 floors.

Factor to write an equivalent expression.(What is the Greatest Common Factor?).<br><br> −9x+15y
KengaRu [80]

Answer:

GCF is 3

Step-by-step explanation:

Given the expression -9x + 15y

First, we need to find ther individual factors

-9x = -3 *3 * x

15y = 3 * 5 * y

Since 3 is common to both factors

−9x+15y = 3(-3x+5y)

Hence the GCF is 3
