A gardener wants to try different combinations of fertilizer (none, 1 cup, 2 cups) and mulch (none, wood chips, pine needles, pl
sattari [20]

Answer:

5

Step-by-step explanation:

First lets identify the number of treatments possible.

1st possibility: no fertilizer, no mulch

2nd possibility: no fertilizer, wood chips

3rd possibility: no fertilizer, pine needles

4th possibility: no fertilizer, plastic

5th possibility: 1 cup fertilizer, no mulch

6th possibility: 1 cup fertilizer, wood chips

7th possibility: 1 cup fertilizer, pine chips

8th possibility: 1 cup fertilizer, plastic

9th possibility: 2 cup fertilizer, no mulch

10th possibility: 2 cup fertilizer, wood chips

11th possibility: 2 cup fertilizer, pine chips

12th possibility: 2 cup fertilizer, plastic

Or we can simply calculate no. of possibilities by elements in set a x elements in set b

Total no. of possibilities = 3 x 4 = 12

To find no. of plants for each treatment divide total number of plants by the total treatments possible.

No. of plants for each treatment = total number of plants/ total number of treatments possible

No. Of plants for each treatment = 60/12

No. of plants for each treatment = 5

Which graph shows that Cindy reads about 3/4 of the time while riding in the car?
wolverine [178]

The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.

<h3>What is Unit Rate?</h3>

Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.

Unite rate (k) = x/y.

In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.

Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.

The volume of a cone is V=1/3*pi*r^2*h

Since the value of r is 6 and the value of h is 8, we get:

V=1/3*pi*6^2*8

V=1/3*pi*36*8

V=12*pi*8

V=96pi

V=301.5928947

So the exact volume of the cone is 301.5928947 m^3

The approximate value of the volume rounded to the nearest tenth is 301.6 m^3
