Describe the points with a double inequality. I need the answer quick. Thanks!

Dominik [7]

Answer:

$- 3 \: < \: x \: < \: 13$

Step-by-step explanation:

We want to describe the solution set on the number line as an inequality.

We have open circles at both ends.

This means the inequalities are not the ones containing equal sign.

The number line started from -3 and ended at 13 non inclusive.

This means the solution set for the inequality are all real numbers greater than -3 but less than 13.

We write this as:

$- 3 \: < \: x \: < \: 13$

In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into 4 suits: spades,

liubo4ka [24]

Answer:

It is more likely she draws 2 red cards

Step-by-step explanation:

Given that:

Number of red d cards in deck = 26

Number of face cards = 4 * 3 = 12 face cards

If two cards are drawn with replacement ;

Probability = (required outcome / Total possible outcomes)

P(1st card red) = 26 /52) = 1/2

P(2nd card red) = 26 /52 = 1/2

P(1st card red) * P(2nd card red)

1/2 * 1/2 = 1/4 = 0.25

P(1st card face card) = 12/52 = 3/13

P(2nd card, face card) = 12/52 = 3/13

P(1st card face card) * P(2nd card face card)

3/13 * 3 /13 = 9/169 = 0.053

0.25 > 0.053

It is more likely she draws 2 red cards
