Answer:

38,400 bacteria

Step-by-step explanation:

Because there are 24 hours in a day, it will double 4 times

2400times 2 equals 4800 (1st)

4800 times 2 equals 9600 (2nd)

9600 times 2 equals 19200 (3rd)

19200 times 2 equals 38400 (4th)

The radio of boys to girls in Miss ronilo's math class is 3 to 1 what percent of the classes is girls
9966 [12]

Imagine that the class only had 4 students (unrealistic most likely, but small numbers help much better I think)

If we had 4 students and 3 were boys, then 4-3 = 1 girl is in the class. This makes the ratio of boys to girls be 3 to 1. In other words, there are 3 times as many boys compared to girls.

Divide the number of girls (1) over the number of students total (4) to get 1/4 = 0.25 = 25%

<h3>Answer: 25%</h3>

In a city, 60% of the residents live in houses and 40% of the residents live in apartments.Of the people who live in houses, 20%
DIA [1.3K]

Answer:

0.75 or 75%

Step-by-step explanation:

The probability that a resident lives in a house and owns their own business is:

P(H\cap B)=0.6*0.2\\P(H\cap B)=0.12

The probability that a resident lives in an apartment and owns their own business is:

P(A\cap B)=0.4*0.1\\P(A\cap B)=0.04

Therefore, the probability that a person lives in a house, given that they own their own business is:

P(H|B) = \frac{P(H\cap B)}{P(H\cap B)+P(A\cap B)}\\P(H|B) = \frac{0.12}{0.12+0.04} \\P(H|B) = 0.75

The probability is 0.75 or 75%.
