The number 66 is increased to 72. What is the percentage by which the number was increased, to the nearest tenth of a percent?

Lunna [17]

Answer:

The increase is 9.1%

Step-by-step explanation:

Step 1: Make an equation

$66 * x = 72$

$66x = 72$

Step 2: Divide both sides by 66

$66x / 66 = 72 / 66$

$x = 1.09090$

Step 3: Find the increased

$1 - 1.09090$

$0.091 * 100$

9.1%

Answer: The increase is 9.1%

If you draw a card with a value of 4 or less from a standard deck of cards, I will pay you 165$ if not your pay me $45. (Aces ar

jekas [21]

Answer: The required expected value is $3.46.

Step-by-step explanation:

Since we have given that

Number of value of 4 or less are

2,3,4

So, there are 12 in numbers.

So, probability would be

$\dfrac{12}{52}$

Since Aces are considered as the highest card in the deck.

So, remaining probability would be

$\dfrac{40}{12}$

Amount paid or value of 4 or less = $165

Amount not paid for other case = $45

So, the expected value would be

$\dfrac{12}{52}\times 165-\dfrac{40}{52}\times 45\\\\=\dfrac{1980}{52}-\dfrac{1800}{52}\\\\=\dfrac{180}{52}\\\\=3.46$

Hence, the required expected value is $3.46.

The question says 5k+6k+4k=90. What does k equal?

alina1380 [7]

$5k+6k+4k=90 \\ \\ 15k = 90 \ / \ simplify \\ \\ k = \frac{90}{15} \ / \ divide \ each \ side \ by \ 15 \\ \\ k = 6 \ / \ simplify \\ \\$

The final result is, k = 6.
