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 :)
Since the variance is the square of the standard deviation, the variance here is 6.3.
A commonly used measure of dispersion is the standard deviation, which is simply the square root of the variance. Therefore, we just raise the standard deviation to the power of 2 to get the answer. We do as follows:
s = √v
(2.5)² = (√v)²
v = 6.25 = 6.3
So, Since the variance is the square of the standard deviation, the variance here is 6.3.

Question
Ms. Johnson uses a statistics program to analyze all the data collected by her students during a lab experiment about the acceleration due to gravity. The program reports a mean of 31.5 and a standard deviation of 2.5. What is the variance of the data?

Answer:
Step-by-step explanation:
f(x) = -2(x − 4^)2+ 2
The vertex is (4,2)
so the axis of symmetry is is x=4
g(x) = 5x^2− 10x + 7
h= -b/2a = 10/2(5) = 10/10 =1
The axis of symmetry is at x=1
h(x) the axis of symmetry is at x=-2

1/5 * 40 = 8
1/4 * 40 = 10
8+10=18
40-18=22

A balanced coin will have 50:50 chance of showing either head or tail. In this question, you are asked the probability to find the first head after two tosses. That means the toss result should be:
1. tail = 1/2 probability
2. head = 1/2 probability
Previously you are tossing the coin 10 times and obtain zero head. But this previous 10 tosses result should not influence your probability in the 11th and 12th toss. The chance will always be 50:50 no matter how much the tosses count. So the probability should be: 1/2 * 1/2= 1/4
