There are 12 people ( 4  8 = 12)

There are 4 male.

The probability of picking a male would be the number of males over the total number of people.

Probability = 4/12 which reduces to 1/3

Answer:

Your answer is 5 weeks!!

Step-by-step explanation:

How I got my answer; First I checked if 2 weeks would work by doing 2( the umber of weeks) *3( the number of inches it grows per week) which is 6, I then added 6 to 3 inches (which is the original height of the plant) and I got 9.

I did the same process with the 2nd plant;

2(the number of weeks) *2( the number of inches the plant grows per week) which is 4. I then added 4 and 8( the original height) and I got 12.

(THE EXPLANATION FOR HOW I GOT 5 WEEKS STARTS HERE)

So I continued to do this process with 2,3,4 and 5, and finally I got my answer at 5weeks.

5(the number of weeks) * 3(the rate the plant grows per week) which is 15inches. I then added 15 to the original height which is 3inches, 15 +3 is 18 inches so that is my answer for how tall the 1st plant would get in 5 weeks .

Now the 2nd plant;

5(the number of weeks) * 2(the rate the plant grows per week) which is 10inches. Now I'm going to add the original height (8) with the rate the 2nd plant would grow after 5 weeks (10), 10+8 is 18 so the plant would grow 18inches after 5 weeks which is the same height as the first plant.

Hope this makes sense :)

The temperature in St. Louis, Missouri, is 31°F. The temperature in Duluth, Minnesota, is -29°F. Is the temperature in St. Louis
Sati [7]

-29 is 29 degrees away from 0 degrees.

31 is 31 degrees away from 0 degrees.

-29 (the temperature in Duluth) is closer to 0, because 29 is less than 31.
