What is the total amount of fabric needed to make the tent with the following dimensions?
lesantik [10]
I’m just guessing that it’s asking for surface area, since fabric doesn’t fully fill an object.

I kind of forgot about surface area so this isn’t going to be 100% accurate, but I believe that you multiply the base by the other numbers.
For example, you get the base of the side, 6 ft. , and you multiply it by the height, which gives 24. Then, you multiply it by 2, since there’s two sides.

Then you do 6x5 (30), and so on and so forth.

(I’m so sorry if I’m wrong, I haven’t really done area or surface area in a while lol)

Eggs that are contaminated with salmonella can cause food poisoning among consumers. A large egg producer takes an SRS of 200 eg
Paladinen [302]

Answer:

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Step-by-step explanation:

The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.

In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.

Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.

The answer is Option A: "0.2% is a parameter and 11 is a statistic".

svetlana [45]

Answer:

10.8kg

Step-by-step explanation:

Before he was on the diet he already weighed 80 kilograms, so it is not important to determining how much weight we gains in two months.  Instead we need to focus on the 5.4t part of the equation.  t represents the number of months so we need to substitute 2 for t and you get

5.4t

5.4(2)

10.8kg
