Easy 6th grade question

Ivan

Answer:

1/4

Step-by-step explanation:

There are 54 cards in a deck including jokers, so if you count how many face cards there are and jokers and subtract them from 54 you get 40, then you divide 40 by 2 to get 20/40 since it is even numbered and half of the time you would get an even number. then you divide the die by 2 to get 1/2 and multiply them to get your answer 1/4.

Oops some miscalculations.

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type your answers in the box. ƒ -

Bad White [126]

ƒ(x) = 1/2x + 4

inverse

x = 1/2 y + 4
2x = y + 8
y = 2x - 8
so inverse f-1(x) = 2x - 8

ƒ -1(4) = 2(4) - 8 = 0

answer

ƒ -1(x) = 2x - 8
ƒ -1(4) = 0

What is the probability of drawing the compliment of a king or a

inna [77]

Answer:

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

Step-by-step explanation:

Step(i):-

Let 'S' be the sample space associated with the drawing of a card

n (S) = 52C₁ = 52

Let E₁ be the event of the card drawn being a king

$n( E_{1} ) = 4 _{C_{1} } = 4$

Let E₂ be the event of the card drawn being a queen

$n( E_{2} ) = 4 _{C_{1} } = 4$

But E₁ and E₂ are mutually exclusive events

since E₁ U E₂ is the event of drawing a king or a queen

step(ii):-

The probability of drawing of a king or a queen from a standard deck of playing cards

P( E₁ U E₂ ) = P(E₁) +P(E₂)

$= \frac{4}{52} + \frac{4}{52}$

P( E₁ U E₂ ) = $\frac{8}{52}$

step(iii):-

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards

$P(E_{1}UE_{2}) ^{-} = 1- P(E_{1} U E_{2} )$

$P(E_{1}UE_{2}) ^{-} = 1- \frac{8}{52}$

$P(E_{1}UE_{2}) ^{-} = \frac{52-8}{52} = \frac{44}{52} = 0.846$

Conclusion:-

The probability of drawing the compliment of a king or a queen from a standard deck of playing cards = 0.846

Find the 12th term of the arithmetic sequence 2x + 8,6x + 5, 10x + 2, ...

lawyer [7]

Answer: The 12th term is 46x -25

Step-by-step explanation:

It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.
