What is square root of the product of the number z and itself​

Mathematics

Answer:

\large\boxed{z}

Step-by-step explanation:

What is square root of the product of the number z and itself?

Break down into smaller parts

What is the product of the number z and itself?

Product = multiply

Write an equation multiplying z by itself

z * z

Bring back the full question: What is the square root of the product of the number z and itself?

Now we can just add a \sqrt{} to the front of our equation to solve the problem.

\sqrt{z * z}

Simplify

z * z = z^{2}

\sqrt{z^{2} }

In this case, the square root cancels out the exponent (z^{2}), so \sqrt{z^{2} } can simplify to z.

Hope this helps :)

Find the missing probability.<br> P(A) = 0.4; P(B) = 0.7; P(A or B)<br> ; P(A and B) = 0.3
solong [7]

Given:

P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3

To find:

The value of P(A\text{ or }B).

Solution:

We know that,

P(A\text{ and }B)=P(A\cap B)

P(A\text{ or }B)=P(A\cup B)

It means, we have P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3 and we need to find the value of  P(A\cup B).

P(A\cup B)=P(A)+P(B)-P(A\cap B)

P(A\cup B)=0.4+0.7-0.3

P(A\cup B)=1.1-0.3

P(A\cup B)=0.8

Therefore, the value of P(A\text{ or }B) is 0.8.
