This is the range of sample statistics obtained when many samples are selected?

Answers

Answer 1

The range of sample statistics obtained when many samples are selected is a sampling distribution. A sampling distribution is also a probability distribution of the statistics obtained in the large number of samples drawn from a specific population. It also shows every possible result that the statistic can take in every possible sample from the population and how often will each results happens.

What is the point slope form of the line with slope 2/5 that passes through the point (−4, −7) ?

Answers

The given slope is 2/5 and the line passes through the point (-4,-7)

The equation for the line in the point-slope form is
[tex] \frac{y-(-7)}{x-(-4)} = \frac{2}{5} \\\\ \frac{y+7}{x+4} = \frac{2}{5} [/tex]
That is,
[tex]y+7= \frac{2}{5} (x+4)[/tex]

Answer:
[tex]y+7= \frac{2}{5} (x+4)[/tex]

Determine the linear factors for x4-2x^2+1

Answers

Use a substitution: let b = x^2
Then b^2 = x^4.

Now you need to factor

b^2 - 2b + 1 =

(b - 1)^2

Since b = x^2, now we replace b with x^2 and factor again.

(x^2 - 1)^2 is the square of a difference of squares.

= (x^2 - 1)(x^2 - 1)

=(x + 1)(x - 1)(x + 1)(x - 1)

= (x + 1)^2(x - 1)^2

Didn't you mean x^4-2x^2+1 ?

Choose "p" to represent x^2. Then p^2 - 2p + 1 = (p-1)(p-1)

These results are equivalent to (x^2-1)(x^2+1).

x^2-1 can be factored: (x-1)(x+1)

x^2-1 (again) can be factored: (x-1)(x+1)

Then the factored expression is (x-1)^2 * (x+1)^2.

Check this by multiplication. Do you obtain x^4 - 2x^2 + 1?

"1. how many ancestors does a node at level n in a binary tree have? provide justification."

Answers

In binary tree there are n ancestor at level n.

Proof :

Take P(0): At node level 0, it has no ancestors since this is a roo tnode.

Take P(1): At node level 1, it has one ancestor. The ancestor is the root, its parents which is at level 0.

Take P(K): A node level K it has K ancestors. Its parent is at level K – 1.

Take P(K+1): At node K + 1 level have more than one ancestor than that of node at k level.

Thus there are n ancestor at level n in binary tree.

A node at level n in a binary tree has n ancestors. This is because there are n nodes on the path from the root to the node itself.

In a binary tree, the ancestors of a node are all the nodes that appear on the path from the root of the tree to that node. The level of a node is defined as its distance from the root node, with the root node being at level 0.

To determine the number of ancestors of a node at level n, consider the following:

The node at the root (level 0) has 0 ancestors.A node at level 1 has the root node as its ancestor (1 ancestor).In general, a node at level n has n - 1 nodes on the path from the root to the node.Therefore, a node at level n in a binary tree has n ancestors because it includes all nodes from the root (level 0) to the node itself (excluding the node itself).

Hence, the number of ancestors for a node at level n is simply n.

Your computer monitor has a width of 14.80 inches and a height of 11.10 inches. what is the area of the monitor display in square meters?

Answers

Note that
1 inch = 0.0254 m

Given:
Width = 14.80 inches = 14.80*0.0254 m = 0.3759 m
Height = 11.10 inches = 11.10*0.0254 m = 0.2819 m

By definition,
Area = Width * Height
= 0.3759*0.2819 m²
= 0.106 m²

Answer: 0.106 m²
