A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check a

Vinvika [58]

We have to find slopes one by one.

$\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}$

(0,1)
(12,3)

$\\ \sf\longmapsto \dfrac{3-1}{12-0}$

$\\ \sf\longmapsto \dfrac{2}{12}$

$\\ \sf\longmapsto \dfrac{1}{6}>0$

Line passes through this.

(-2,-5)

$\\ \sf\longmapsto \dfrac{-5-1}{-2-0}$

$\\ \sf\longmapsto \dfrac{-6}{-2}$

$\\ \sf\longmapsto 3>0$

Line passes through this

(-3,1)

$\\ \sf\longmapsto \dfrac{1-1}{-3-0}$

$\\ \sf\longmapsto \dfrac{0}{-3}=0$

Not possible (Line passes through y axis as one co-ordinate is (0,1))

( 1,15)

$\\ \sf\longmapsto \dfrac{15-1}{1-0}$

$\\ \sf\longmapsto \dfrac{14}{1}$

$\\ \sf\longmapsto 14>0$

Line passes through this

(5,-2)

$\\ \sf\longmapsto \dfrac{-2-1}{5-0}$

$\\ \sf\longmapsto \dfrac{-3}{5}$

Line doesnot pass through this.

Given a feedlot of about 2500 cows, if an individual cow produces about 40 liters of manure per day, how many kiloliters of manu

Grace [21]

Answer:

3000 kL

Step-by-step explanation:

(2500 cows)(40 L/day/cow)(30 day/mo)(1 kL/(1000 L)) = 2.5×40×30 kL/mo

= 3000 kL/mo

About 3000 kL of manure would be produced in one month.

___

That's about 3 cubic meters.

Grace [21]

Answer:

No, there is not a significant difference

Step-by-step explanation:

The sample mean (1.3) is less than the sample standard deviation (1.9). The sample mean would have to be greater than 1.9 for there to be a significant difference
