2.3 as a simplified fraction is 23/10, 2 and 3/10, or even as a percentage, 230%.

Hope this helps, if not, comment below please!!!

5x-y=12 ............................

5x−y=12 Subtract 5x from both sides of the equation.

− y = 12 − 5 x Divide each term in

− y = 12 − 5 x by - 1 and simplify

y = - 12 + 5 x

i don't know if thats what your answer was but there you go

In a volleyball game, a player on one team spikes the ball over the net when the ball is 10 feet above the court. The spike driv

Fynjy0 [20]

Answer:

4.75 seconds

Step-by-step explanation:

Initial height of the ball from the ground = 10 feet

Upward initial velocity given = 55 feet per second

Value of g ( acceleration due to gravity) = 32.2 feet per s²

Motion of the ball:

The ball first goes vertically upwards, gravity decelerates the body and it momentarily comes to rest at a point in its upward trajectory, which is the point of maximum height. From this point, to the ground, the ball behaves as a freely dropped body.

Till the ball reaches its maximum height:

u = + 55

v = 0 ( final velocity is zero)

a = - 32.2 (since it is deceleration)

we know that v = u + at

⇒ 0 = 55 - 32.2t

⇒ t = 1.7 s

Also , we have s = ut + (1/2)at²

Here, s is the maximum height from the point where ball is thrown

So, s = 55(1.7) - (0.5)(32.2)(1.7)(1.7)

⇒ s = 140 feet

So at a height of 140 feet + 10 feet (initial height) = 150 feet, the ball acts as a freely dropped body.

Here, u = 0

a = +32.2

s= 150

s = ut + (1/2)at²

⇒ 150 = 0.5 ( 32.2) (t²)

⇒ t² = 300/32.2 = 9.31

⇒ t = 3.05 sec

So total time = 1.7 + 3.05 = 4.75 seconds

Scenario 1: You and a friend take turns choosing cards at random from a deck containing 13 red cards and 13 black ones. Once you

Kisachek [45]

Note that both scenarios are similar, the only difference is that in scenario 1, the selected card is not returned to the deck and in scenario 2 the card is returned to the original deck.
Therefore, scenario 1 is dependent, since it "depends" on the selected cards before. If on the first attempt you have 13 blacks and 13 reds and you select a red one, then for the second attempt you will have 13 blacks and 12 reds, so this time you will have more chances of getting a black card. Scenario 2 is independent, because when you return the selected card to the deck you will always have 13 red and 13 black cards in each attempt, so each event will be independent of the previous one. Finally, as it was explained above the probability of selecting two red faces are different in each scenario
