For this case, the first thing we must take into account is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values we have:
Trip 1:
50 = v * t1
We cleared t1:
t2 = (50) * (1 / v)
Trip 2:
300 = (3 * v) * t2
We cleared t2:
t2 = (300/3) * (1 / v)
t2 = (100) * (1 / v)
Rewriting:
t2 = 2 (50) * (1 / v)
t2 = 2 * t1
Answer:
His new time compared with the old time was:
Twice the old time.
t2 = 2 * t1.
704 ( I'm assuming this is rectangular prism )
Follow this formula:
width x length x height = volume
Base is height x length so half of the problem is solved. Next just multiply that by the width and you found your answer.
Answer:
<h3>Option c)
![H_a:\mu](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3C18)
is correct</h3><h3>
The alternate hypothesis for the significance test is ![H_a:\mu](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3C18)
</h3>
Step-by-step explanation:
The alternate hypothesis use the sumbol for the population value
Let p be the proportion , Mean be
and stadard deviation be ![\sigma](https://tex.z-dn.net/?f=%5Csigma)
The null hypothesis states that population value is equal to the value mentioned in the given claim.
(by given).
The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )
∴ ![H_a:\mu](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3C18)
The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.
<h3>∴ option c)
![H_a:\mu](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3C18)
is correct.</h3>
2 1/4 * 1 3/8 = 3 3/32 or 99/32
