A good advancement would be a portable radio.  They have made life easier for people who are walking/hiking and are looking for something such as the weather for the night or the score for a sports game.

A deck of playing cards has 52 cards, of which 13 are diamonds. If you shuffle the deck well and turn over the top 4 cards, one
vampirchik [111]

Answer:

The correct solution is "0.002". A further solution is given below.

Explanation:

The given values are:

The total number of playing cards,

= 52 cards

Total number of diamonds,

= 13

Now,

The probability of top four cards will be:

= P(First \ diamond)\times P(Second \ diamond)\times P(Third \ diamond)\times P(Fourth \ diamond)On putting the values, we get

= \frac{13}{52}\times \frac{12}{51}\times \frac{11}{50}\times \frac{10}{49}

= 0.25\times 0.23\times 0.22\times 0.20

= 0.002

Please...Im lost with this question (AP Psych)
andriy [413]
For the first one you can use learning that Kaylee has research that some spiders are very venomous and can cause serious harm to other organisms so this contributed to her fear. For the biological/evolutionary approach you can say that through early(or earlier) human’s experiences, spiders have been proven to be dangerous and caused fear that has remained throughout all this time in order to help help us survive. I’m not sure about OCD. Sorry:/

Huge help needed ! im lost and need an explanation to the correct answer.

Answer:

m<MON = 100°

Explanation:

Given:

Area of shaded sector LOM = 2π cm²

NL = 6 cm

Required:

m<MON

Solution:

m<MON = 180° - m<LOM (angles in a straight line)

We don't know m<LOM. Therefore, let's find m<LOM.

Area of a sector = θ/360 × πr²

Area of sector LOM = 2π cm²

r = 3 cm

θ = m<LOM = ?

Plug in the values

2π = m<LOM/360 × π × 3²

2π = m<LOM/360 × 9π

2π = m<LOM × 9π/360

2π = m<LOM × π/40

Multiply both sides by 40

2π × 40 = m<LOM × π

80π = m<LOM × π

Divide both sides by π

80π/π = m<LOM

80 = m<LOM

m<LOM = 80°

✔️m<MON = 180° - m<LOM (angles in a straight line)

Substitute

m<MON = 180° - 80°

m<MON = 100°
