Answer: The answer is 81
Step-by-step explanation:
because 9x9=81 so u don't multiply the whole square like this
9x9x9x9=36 thats wrong and that was my mistake but yeah it would be 81.
If the three slashes are 190, 195, and 200, we can see it as
<span>-l----------l--------|--l- with the slightly longer line being around 198.78. Since it is clearly closer to the end of the line than the start of the line, we round it to 200</span>
Answer:
no
Step-by-step explanation: because a statistical question means tthat you can find proof for example how many slices of pizza did i eat out 12? that you can answer
First you add seven to both sides to 2/3x - 7 = 11 will be 2/3x = 18 then you divide by 2/3 on both sides to get x by itself so 2/3x = 18 and x will be 1/27 in fraction form
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".
The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".
Solution to the problem
Let X the random variable who represents the variable of interest. We know from the problem that the distribution for the random variable X is given by:
We select a sample of size n=64. That represent the sample size.
From the central limit theorem we know that the distribution for the sample mean
is given by:
The mean for the sample distirbution would be given by:

And the deviation given by:

And then the distribution for the sample mean is:
