Ok so i think you could do the leg wax, salt scrub, and the aroma bliss for $149.00 in total. Then the time would be 155 mins which would be almost 3 hours. for the time.

Please help, due in an hour. Two sides of a triangle are 12cm and 8cm. Complete the inequality to show the possible lengths for

lara [203]

Answer:

$4 < x < 20$

Step-by-step explanation:

By the triangle inequality theorem, the sum of the length of the two smaller sides must be greater than the length of the largest side. If 12 cm was the length of the largest side, notice that $8+x > 12 \Rightarrow x > 4$ . Similarly, if x was the length of the largest side, we'd get the inequality $12+8 > x \Rightarrow 20 > x$ . Combining these inequalities, we get $\boxed{4 < x < 20}$ .

You wonder what is the average number of credits Le Moyne students take per semester. You speak with the Le Moyne registrar, and

Ivan

Answer:

The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.

Step-by-step explanation:

Central Limit Theorem

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.

Assume that the population mean is 17 credits and the populations standard deviation is 2.5 credits.

This means that $\mu = 17, \sigma = 2.5$

What does the CLT say about the distribution of the sample mean of 49 students?

It is approximately normal.

The mean is 17.

Due to the sample of 49, n = 49, and the standard deviation is $s = \frac{2.5}{\sqrt{49}} = 0.3571$

The CLT says that the distribution is approximately normal, with mean of 17 credits and standard deviation of 0.3571 credits.
