Answer:
z = 36 rolls , probability for getting 7 = 1/6
Step-by-step explanation:
A die has 6 possible outcomes, which sums to 36 for two dice for every value on both dice.
The outcomes for rolling both dice for 36 times gives 6 possible outcomes summing to 7, that is, (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).
There the probability of getting a sum dice of 7 is:
= 6 / 36 = 1/6
Answer:

Step-by-step explanation:

multiply both sides by 36

Answer:
The following display from a TI-84 Plus calculator presents a 99% confidence interval for a proportion.Fill in the blanks:
We are ____99%____ confident that the population mean is between ___0.385631____ and ___0.780609____.
c) 99%, 0.385631, 0.780609
Step-by-step explanation:
This is the only correct option, given the relevant population mean range. Option B is not correct as the population mean cannot range between 0 and 0.583120 as given by the option. Options 'a' and 'd' are not relevant to the question because they have 1% confidence level, instead of the stated 99% confidence level.
Answer:
Food web
Step-by-step explanation:
Food chain describes how each living organism feed.
Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.
Fungi is also a consumer because it absorbs the nutrients available from other living organisms.
Consumers are classified into three types:
1. Carnivores are organisms that feed mainly on animals
2. Herbivores who feed on plants
3. Omnivores who feed on both plants and animals.
A food web describes the relationship between various food chains and how they interact with each other in the eco system.
