Mario and Bowser begin with a hat that has 5 balls in it: 3 are red, 2 are green. Bowser secretly picks a ball and tells Mario i

t is red, although he might be lying about the color. If there is an 80% chance Bowser is lying, what is the probability that Mario draws 2 red balls in a row after Bowser's initial draw?

1) probabillity of getting two red balls in a row is 1/2 (if 80% Bowser is lying)
2) <span>probability of getting 2 red balls in a row is 1/6 (20% Bowser's truth)
3)  overall probability </span>( \frac{4}{5} * \frac{1}{2}) + (\frac{1}{5} * \frac{1}{6}) = \frac{13}{30}

Answer: y = (xm)/3 + b

Step-by-step explanation:

1. Multiply m on both sides

x × m = 3(y - b)

2. Divide by 3 on both sides

(xm)/3 = y - b

3. Add b on both sides

y = (xm)/3 + b

a scientist notes that the number of bacteria in a colony is 50.3, hours later she notes that the number of bacteria has increas
Yuri [45]

The time it would take for the bacteria to reach 1119 is 5.83 hours

<h3>Calculations and Parameters:</h3>

Given the function:

Pt= P_0e^k^t

  • Initial amount= 50
  • amount after 3 hours= 80

To find the exponential growth;

80 = 50e^k^*^3

k= 1.6/3\\k= 0.533

If there is a constant growth, then to get to 1119:

1119= 50e^0^.^5^3^3^*t

3.8 = 0.533*t

t= 5.83 hours

Therefore, it would take 5.83 hours for the bacteria to increase to 1119.
