1 answer:
Luden [163]3 years ago

Answer:

\mu_{x} = 64, \sigma_{x} = 12.83

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu_{x} = \mu and standard deviation \sigma_{x} = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\mu = 64, \sigma = 77, n = 36

So

\mu_{x} = 64, \sigma_{x} = \frac{77}{\sqrt{36}} = 12.83

One leg of a triangle has a measure of 24 units if the hypotenuse measures 25 units what is the lengh of the other leg
marusya05 [52]
If we assume this is a right triangle

 for a right triangle
if it has legs length a and b and hyptonouse c then
a²+b²=c²

given
a leg is 24
hyptonuse =25
the other leg is b

24²+b²=25²
576+b²=625
minus 576 from both sides
b²=49
sqrt both sides
b=7

the other leg is 7 units
