Answer:
864 in²
Step-by-step explanation:
Use the pythagorean theorem to find the missing side.
36²+x²=60² (x is the missing length of the side)
1296 + x² = 3600
x² = 2304
x = 48
Then use the area of a triangle formula: base·height/2
Substituting 36 for the height and 48 for the base, we get:
48·36/2, which is <u>864</u>.
Answer:
Part A: x÷3=$499
Part B: $1497
Step-by-step explanation:
A: Because to find a fraction of somthing we have to divide, so in this case we divided the original price by 3 to get $499.
B:To find the original price we have to multiply the one third of it ($499) by 3 to get the original amount.
Answer:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
Let X the random variable of interest for a population. We know from the problem that the distribution for the random variable X is given by:
We take a sample of n=64 . That represent the sample size.
The sample mean is defined as:

And if we find the expected value and variance for the sample mean we got:

Var(\bar X) = \frac{\sigma^2}{n}[/tex]
The distribution for the sample mean is given by:
The only possible answer is
X= 0
Hope this is correct and good luckk!!!! :)
