Answer:

z = 1.00

Explanation:

Given:

Probability of z value = 0.6826

By using standard normal table for z value.

P(-z < Z < z) = 0.6826

P(Z < z) - P(Z < -z) = 0.6826

We know that

P(Z < z) + P(Z < -z) = 1

So,

2P(Z < z) - 1 = 0.6826

2P(Z < z) = 1 + 0.6826

2P(Z < z) = 1.6826

P(Z < z) = 1.6826 / 2

P(Z < z) = 0.8413

So,

P(Z < 1.00) = 0.8413

z = 1.00

Jack invested $500 in the shares of a company x and $750

-BARSIC- [3]

Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

First step is to calculate x return on investment

x return on investment = $600 - $500

x return on investment= $100

Second step is to calculate y return on investment

y return on investment= $900 - $750

y return on investment= $150

Now let determine the ratio of return on investment from company x to that from company y

Using this formula

Ratio of return on investment=x return on investment/y return on investment

Let plug in the formula

Ratio of return on investment=100/150

Ratio of return on investment=2/3

Ratio of return on investment=2:3

Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

The substage of sensorimotor development which this behavior reflect is an active experimentation.

<h3>What is an active experimentation?</h3>

An active experimentation can be defined as a substage of sensorimotor development which is typically characterized by the use of theories in order to proffer solutions to problems or make decisions.

In this context, we can infer and logically deduce that the substage of sensorimotor development which Dennis' behavior reflect is known as an active experimentation.
