On average, Tanner has noticed that 22 trains pass by his house daily (24 hours) on the nearby train tracks. What is the probabi
blondinia [14]

Answer:

0.11069

Step-by-step explanation:

We will assume that the trains pass by his house following a uniform distribution with values between 0 and 24. The probability of a train passing on a 9-hour time period is 9/24 = 3/8 = 0.375. Lets call Y the amount of trains passing by his house during that 9-hour period. Y follows a Binomail distribution with parameters 22 and 0.375.

P(Y ≤ 5) = P(Y = 0) + P(Y=1) + P(Y=2) + P(Y=3) + P(Y=4) + P(Y=5) =

{22 \choose 0} * 0.375^0*(1-0.375)^{22} + {22 \choose 1}*0.375^1*(1-0.375)^{21} +\\\\{22 \choose 2} * 0.375^2*(1-0.375)^{20} + {22 \choose 3}*0.375^3*(1-0.375)^{19}  + \\{22 \choose 4} * 0.375^4*(1-0.375)^{18} + {22 \choose 5}*0.375^5*(1-0.375)^{17} = 0.11069

I hope that works for you!

2(3x+2)=2x+28<br><br> What is x?
kherson [118]

Answer:

x = 6

Step-by-step explanation:

<u>Step 1:  Distribute </u>

2(3x + 2) = 2x + 28

(2 * 3x) + (2 * 2) = 2x + 28

(6x) + (4) = 2x + 28

<u>Step 2:  Subtract 2x from both sides </u>

6x + 4 - 2x = 2x + 28 - 2x

4x + 4 = 28

<u>Step 3:  Subtract 4 from both sides </u>

4x + 4 - 4 = 28 - 4

4x = 24

<u>Step 4:  Divide both sides by 4 </u>

4x / 4 = 24 / 4

<em>x = 6 </em>

Answer:  x = 6
