Name the property the equation illustrates (ab)3=a(b3)
Anvisha [2.4K]
The answer to this rests on knowing that there are four properties of multiplication (which your teacher will likely expect you to know...):

These are:
1. commutative
2. associative
3. multiplicative identity
4. distributive

I won't define each of these -- they should be in your notes or textbook. Look them up.

In this case, we are multiplying three terms together -- on the left hand side the parentheses mean to multiply a and b first, then multiply that by 3. On the right hand side, we multiply b times 3 first, and then multiply the product by a.

This would be an example of the associative property of multiplication: when three or more factors are multiplied together, the product is the same regardless of how the factors are grouped.

Hope this helps!

Good luck

forsale [732]

Answer:

700 lbs and 3.742

Step-by-step explanation:

Given that raw materials are studied for contamination. Suppose that the number of particles of contamination per pound of material is a Poisson random variable with a mean of 0.02 particle per pound.

a) To get 14 particles of contamination we must have

expected number of pounds = \frac{14}{0.02} \\=700

b) Since for 700 pounds particles expected are 14 we can say in  a Poisson distribution mean and variance are equal

i.e. Var (700 lbs to obtain 14 particles of contamination ) = 14

Std deviation =\sqrt{14} =3.742
