- <em>There are 30 experimental units in the experiment, which are the 30: the thirty sheets of metal.</em>
Explanation:
This table shows you how the <em>experimental</em> units, <em>sheets of metal</em>, were treated:
Metal 1 Metal 2 Metal 3 Total
Paint A 5 5 5 15
Paint B 5 5 5 15
Total 10 10 10 30
Fifteen sheets (units) were treated with <em>paint A</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
Fifteen sheets (units) were treated with <em>paint B</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
White-headed woodpeckers are adapted to have strong beaks that can break into tree trunks to find bugs and can also open pine cones to get at the seeds. White-headed woodpeckers are best adapted to living in the biome of the<u> temperate rain forest</u>
Explanation:
- The white-headed woodpecker is a non-migratory woodpecker that resides in pine forests of the mountains of western North America. It has a black body and white head. It has white primary feathers that form a crescent in flight.
- White-headed Woodpeckers feed heavily on large pine seeds, and are most associated with old-growth ponderosa pine and sugar pine forests. They also often use recently burned areas.
- The white-headed woodpecker is a non-migratory woodpecker that resides in pine forests of the mountains of western North America.
- Temperate rainforests are coniferous or broadleaf forests that occur in the temperate zone and receive heavy rainfall.
- White-headed woodpeckers are adapted to have strong beaks that can break into tree trunks to find bugs and can also open pine cones to get at the seeds.

- The white-headed woodpecker is a non-migratory woodpecker that also resides in pine forests of the mountains of western North America.
Answer:
You should not because this can cause a grease fire. Grease fires, unlike traditional fires, cannot be put out with water, which can increase the risk of the fire rapidly spreading.
Answer:
A and B are not independent
Explanation:
Given


Required
Determine if A and B are independent
If A and B are independent, then:

Substitute values for P(A) and P(B)


The calculated value of P(A n B) and the given value of P(A n B) are not equal.
i.e.

<em>Hence, A and B are not independent</em>
Answer:
Not 100% sure but I imagine it would have to be Choice A. Reasoning below
Explanation:
- It is between choice A or C since they contradict each other.
- Dams are used to create sources of electricity by backing water up and creating a pool of potential energy.
- This backing up water creates a reservoir upstream, thus increasing the available freshwater in the reservoir.
