QUICK!!! TAKING A TEST RN!!! 30 POINTS!!!A water tank has 22 gallons of water. It begins to receive 26 gallons per hour for a nu
Citrus2011 [14]

Hey there!!

Let's take 'h' as the number of hours.

The volume already present is "22" gallons.

Hence, this would become the y-intercept.

... ( 0 , 22 )

... The slope would be 26

Hence, y would be 516 and m would be 26 and x would be h.

Slope-intercept form :-

y = mx + b

( m is the slope and b is the y-intercept )

... 516 = 26h + 22

... 516 - 22 = 26h

... 494 = 26h

... h = 494 / 26

... h = 19

<em>Hence, the number of hours would be 19. </em>

Hope my answer helps!

Use the formula for the probability of the complement of an event. A coin is flipped 4 times. What is the probability of getting
raketka [301]

Answer: 15/16

Step-by-step explanation:

There will be 16 outcomes for 4 coins=2^4

Probability of only head is : P(C)=1/16

P(C) + P(C') = 1

P(C') = 1 - P(C)

P(C') = 1 - 1/16

Take the l.c.m

P(C') = (16-1) / 16

P(C') = 15/16

So the probability of getting at least 1 tail is 15/16
