Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

What is the 95% CI for data set 2?
vesna_86 [32]

Answer: 20 ± 11.32

Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.

For the data set 2, z-value for 95% confidence interval is z = 1.96

Formula to calculate CI is

x ± z\frac{s}{\sqrt{n} }

where

x is mean

z is z-value

s is standard deviation

n is the sample number

Then:

20 ± 1.96\frac{10}{\sqrt{3} }

20 ± 1.96\frac{10}{1.7320}

20 ± \frac{19.6}{1.7320}

20 ± 11.32

The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.

Could producers survive without consumers? explain why or why not
arlik [135]
Producers could not survive without consumers. Produces rely on consumers to purchase their product, if no one buy their product, then the producer has no money to even produce anything. This like a car, the car is the producer, and the gas is the consumer, the car will not work unless there is gas. So a producer will not survive without the consumer.
