1/2 X base X height= triangle
length X width X height= square
I cant see the triangle so its kinda hard to know
I think the answer is 1/3 because you can simplify 4/12 into 2/6 and that can also be simplify into 1/3. Sorry if I am wrong let me know if i'm right
Answer:
1. A matched-pairs t-test is valid, despite the sample being a small representation of the population, because the sample is a simple random sample and has a distribution with a single peak.
Step-by-step explanation:
The matched-pairs test is valid, for the reasons given in choice 1. Here's why:
- We do have matched pairs, not a 2-sample t-test, because each two are paired by the house they live in. Husband and wife live together: it's safe to pair them. (This rules out option 5.)
- Check conditions: The sample is large enough (fulfilling the <u>sample size condition)</u>. The sample data is fairly normal, although we don't know the population data, and the sample size is over 40, so we consider it a fairly large sample (fulfilling the <u>nearly normal condition)</u>. We don't know about outliers, but we'll have to assume Ted doesn't have any, because they aren't mentioned.
Answer:
C=0.46 s⁻¹
Step-by-step explanation:
The general equation for the damped harmonic system given as
Where
A= Amplitude
C=Damping constant
Lets take at time t= t₁, A= K
And at time t= t₁+3 s ,A= K/4
-----------1
-------------2
From equation 1 and 2
C=0.46 s⁻¹
