Someone please help me with this, it’s due tomorroww I need someone experttt

59 minutes

Step-by-step explanation:

We would apply the formula,

y = ab^t

Where

a represents the initial amount of bacteria.

t represents the doubling time.

From the information given

a = 10000000

t = 20 minutes

Since after 20 minutes, the population doubles, then

y = 2 × 10000000 = 20000000

Therefore

20000000 = 10000000 × b^20

2 = b^20

Raising both sides of the equation by 1/20, it becomes

2^(1/20) = b

The equation becomes

y = 10000000 × 2^(1/20)×t

y = 10000000 × 2^(t/20)

Therefore, the time it will take to get to 67 million microbes would be

67000000 = 10000000 × 2^(t/20)

67000000/10000000 = 2^(t/20)

6.7 = 2^(t/20)

6.7 = 2^(0.05t)

Taking log to base 10 of both sides, it becomes

Log 6.7 = 0.05t log 2

0.826 = 0.05t × 0.301

0.01505t = 0.826

t = 0.826/0.01505

t = 54.88

t = 59 minutes

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
