Which exponent is missing from this equation<br> 5.6=56,000

Neko [114]

Answer:

The missing exponent is 4

Step-by-step explanation:

Let

$5.6 \times {10}^{n} = 56000$

Then we rewrite the LHS in scientific notation to get;

$5.6 \times {10}^{n} = 5.6 \times {10}^{4}$

This implies that,

${10}^{n} = {10}^{4}$

By comparison, we find n=4.

Therefore the missing exponent is 4

The triplets, nick, Brian, and dan, exit their preschool classroom every day in a random order. Create an organized list to show

AfilCa [17]

The set of all possibilities is called sample space and is denoted by S.

So, S = {NBD, NDB, BDN, BND, DBN, DNB} and n(S) = 8

and we need to find the probability of NBD

E = {NBD} and n(E) = 1

The probability of an even is defined by p(E) = $\frac{n(E)}{n(S)}$

Hence, p(E) = $\frac{1}{8}$

Are randomly choosing a person who is left-handed and randomly choosing a person who is right-handed mutually exclusive events?

Masteriza [31]

Answer: No .

Step-by-step explanation:

There are special cases where a person can use right and left hand equally well . I.e ambidextrous .

In statistical terms and probability theory, two events (or propositions) are mutually exclusive or disjoint if they cannot both occur at the same time .however in this case it may occur that the person is right and left handed at the same time .
