<h3>How to define chemical compounds?</h3>

1) The chemical compounds that are present before a reaction occurs is called; reactants

2) The compounds produced from the reaction are called; products

3) Unit of measure, containing Avogadro's number is called; Mole

4) The quantitative proportion of reactants to products is called; Stoichiometry.

5) Two solutions are mixed and an insoluble substance forms; A precipitation reaction

6) An illustration of the reaction that occurs between two or more chemical compounds is called; chemical equation

7) A solid compound that contains water molecules is called hydrates.

A(t)=(t−k)(t−3)(t−6)(t+3) Given that a(2)=0 , what is the absolute value of the product of the zeros of a?

Ugo [173]

So using a(2)=0 we can first solve for k by substituting t for 2
0 = (2-k)(2-3)(2-6)(2+3)
0 = (2-k)(-1)(-4)(5)
0 = (2-k)20
0 = 40 - 20k
-40 = -20k
k = 2

The next step would be to find all the 0s of a.
0 = (t-2)(t-3)(t-6)(t+3)
T = 2,3,6,-3

Then we find the product
2x3x6x-3 = -108

Since the problem asks for the absolute value, the answer is positive 108

The math department at a small school has 5 teachers. The ages of these teachers are 23, 34, 37, 42, and 58. Suppose you select

denis23 [38]

The graph that shows the sampling distribution of the sample minimum age is; Option C Graph

<h3>Sampling distribution</h3>

We are given the ages of the 5 teachers as;

23, 34, 37, 42 and 58.

The options that show the sampling distribution of the sample minimum age has been attached.

Since 4 teachers will be selected out of the 5, it means that the minimum age of the 4 selected teachers will be 23 years of age 4 time while the minimum age will be 34 if the 23 year old teacher is not selected.

In conclusion, the sampling distribution for this scenario of minimum age should show 4 teachers at the 23 year mark and 1 teacher at the 34 year mark.
