<h2><u>Answer:</u></h2>

8.4 / 10 = 0.84

<h2><u>Why?</u></h2>

When you multiply by powers, you move the decimal point to the left.

When you divide powers you move the decimal point to the right.

For example, when you are dividing 8.4 by 10 to the power of 1, or just ten 10,

you need to move the decimal point one place to the right.

Hope this helps!

skelet666 [1.2K]

Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52

  • The domain is the deck of 52 cards
  • codomain is 4 players
  • function, f(k) maps a card to each player
  • It is surjective

This is further explained below.

<h3>What is a surjective Function?</h3>

A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.

To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.

Generally, function, f(k) maps a card to each player

And since each player is dealt 13 cards st 13 of the cards are mapped to each player.

It is a function as one card is mapped to one and only one player.

The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.

In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

Westkost [7]

Answer:

1 1/4 pounds

Step-by-step explanation:

You can write the equation ...

  (1/2) lb = (2/5) × container

Multiplying by the inverse of 2/5 gives ...

  (1/2)·(5/2) lb = container

  5/4 lb = container

  container = 1 1/4 lb

Gnom [1K]

Solution :

The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.

a). $R^2$ does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.

b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.

The regression model provides the prediction and not the actual values.
