Unusual question. 4/5 = 0.8, which is NOT a repeating decimal; it's a rational fraction.

1. f(-6)=12

2. k(-4)=-68

Further explanation:

We have two functions whose values we have to find on certain points.

In order to find the values of function, the value is put in place of variable in the function.

So,

1. f(a) = -2a

We have to find, f(-6)

So putting -6 in function

$f(-6) = -2(-6)\\= 12$

2. k(x) = -3x^2+5x

We have to find, k(-4)

So putting -4 in function

$k(-4)=-3(-4)^2+5(-4)\\=(-3)(16)-20\\=-48-20\\=-68$

A card is drawn from a well-shuffled deck of 52 cards. What is the probability of getting a red 10?

ohaa [14]

Answer:

1/13

Step-by-step explanation:

Knowing that:

In a deck of card half of the deck of card are red: 1/2

Also means 52/2 = 26

There are 2 red 10 in a deck of card.

Solve:

Since there are 2 red 10 in a deck of card and half of the deck of 52 card are red also known as 26.

Thus, the probability of getting a red 10 is 2/26. As you can see that not a answer choice. That because 2/26 is a even number as well as it means that it can be simplify.

GCD (or HCF) of 2 and 26 is 2.

Therefore, divide both by 2.

2/2 = 1

26/2 = 13

Hence, we can see that the simplify form is 1/13.

As a result, the probability of getting a red 10 is 1/13.
