Answer:
99.7%
Step-by-step explanation:
Given that mean (μ) = 394.3 ms and standard deviation (σ) = 84.6 ms.
The empirical rule states that for a normal distribution:
- 68% falls within one standard deviation (μ ± σ)
- 95% falls within two standard deviation (μ ± 2σ)
- 99.7% falls within three standard deviation (μ ± 3σ)
one standard deviation = 394.3 ± 84.6 = (309.7, 478.9). 68% falls within 309.7 and 478.9 ms
two standard deviation = 394.3 ± 2 × 84.6 = (225.1, 563.5). 95% falls within 225.1 and 563.5 ms
three standard deviation = 394.3 ± 3 × 84.6 = (140.5, 648.1). 99.7% falls within 140.5 and 648.1 ms
Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
Answer:
Your answer will be the third function
Step-by-step explanation:
The base function you need to know is h(t)= 1/2at^2
Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12
I assume you mean
, and not
, since this doesn't satisfy the ODE.
Assume a second solution of the form
, where
is a function of
. Then


Substituting into the ODE gives







where we omit the second term because it's already accounted for by
.

I'm in sixth grade, and don't know how to answer 2 and 5. So I'm only going to answer questions 1, 3 and 4. </h2>
really sorry about that
1. Answer = 90m²
3. Answer = 50in²
4. Answer = 108cm²
yup, this is how weird i am
I took the screen shot of answer 3 before 1 lol!

so sorry I couldn't help on all problems
Always have more than 2 smiles so that you can share them to someone who doesn't have one! Me Happy! You Happy! EVERYONE HAPPY!
Thanks!
Have a great day!
