Answer:

See explanation

Step-by-step explanation:

Among 806 people asked which is there favorite seat on a plane, 492 chose the window seat, 8 chose the middle seat, and 306 chose the aisle seat, then

$P(\text{Window seat})=\dfrac{492}{806}=\dfrac{246}{403}\\ \\P(\text{Middle seat})=\dfrac{8}{806}=\dfrac{4}{403}\\ \\P(\text{Aisle seat})=\dfrac{306}{806}=\dfrac{153}{403}$

a) One randomly selected person preferes aisle seat with probability

$\dfrac{153}{403}$

b) Two randomly selected people both prefer aisle seat (with replacement) is

$\dfrac{306}{806}\cdot \dfrac{306}{806}=\dfrac{153}{403}\cdot \dfrac{153}{403}=\dfrac{23,409}{162,409}$

c) Two randomly selected people both prefer aisle seat (without replacement) is

$\dfrac{306}{806}\cdot \dfrac{305}{805}=\dfrac{153}{403}\cdot \dfrac{61}{161}=\dfrac{9,333}{64,883}$

A triangle has a base of 4 units and a height of 3 units. Mark draws the triangle again but doubles the height. How does the are

dexar [7]

Answer:

The area increases by 6 square units.

Step-by-step explanation:

The formula for the area of a triangle is base times height divided by two.

So, first solve 3 times 4 divided by 2.

Simplify 4 and 2 and you get 3 times 2 which = 6

Then Mark doubles it right?

So do 6 times 2 and you get 12

The first answer is 6, so it increased by 6.

I hope this answer helped. Sorry if I was wrong.
