Answer:

8.49 and No

Step-by-step explanation:

C² - b² = a² (pythagorus rule rearranged for a²)

9² - 3² = a²

81 - 9 = a²

a² = 72

a = 8.49 and no they aren't a triple.

X = 6 root 2
Equation: square root of (9 squared - 3 squared)
I believe it is not a triple considering the answer is not a whole number but I could be wrong.

Rewrite the polynomial 6x4 − 24x3 + 72x2 by factoring out the GCF
olya-2409 [2.1K]
The trick here is to recognize one or more factors common to each term.  For example,  6x4 − 24x3 + 72x2 = x^2(6x^2 - 24x + 72), so x^2 is one common factor.  Looking at (6x^2 - 24x + 72), you can easily see that 6 is a common factor, so now we have (6)(x^2)(x^2 - 4x + 12).  These last 3 terms do not have a common factor, so the factoring process stops here:

(6)(x^2)(x^2 - 4x + 12)

The time that a randomly selected individual waits for an elevator in an office building has a uniform distribution over the int
Elanso [62]

Answer:

The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For the population, we have that:

Mean = 0.5

Standard deviaiton = 0.289

Sample of 12

By the Central Limit Theorem

Mean = 0.5

Standard deviation s = \frac{0.289}{\sqrt{12}} = 0.083

The mean of the sampling distribution of x is 0.5 and the standard deviation is 0.083.

Please help me!!! Will get brainliest!!!
Alex73 [517]
Using the formula
A = Pe^kt
Where A is the ending amount of population, P is the population k is a constant and 't' is time.

A = 0.39, t= 12 and p= 0.29
0.39= 0.29e^12k
1.34 = e^12k
ln1.34 = 12k
ln1.34/12 = k
K= 0.02

No the graph does not support his claim as k should be equal to 0.5
