Answer:
P(4.7≤x≤5.3)≈0.6827≈68.27%
Step-by-step explanation:
Notice that 4.7 is 1 standard deviation below the mean (μ) and 5.3 is 1 standard deviation above the mean. Thus, by the Empirical Rule, ±1σ represents about 68.27% of the data in a normal distribution, meaning that P(4.7≤x≤5.3)≈0.6827
Well, input and output are the functions so look up how to do functions with input and output and you will get the answer or look at this picture
Answer:
We have the matrix
To find the eigenvalues of A we need find the zeros of the polynomial characteristic
Then
Now, we fin the zeros of .
Then, the eigenvalues of A are of multiplicity 1 and
of multiplicity 2.
Let's find the eigenspaces of A. For :
.Then, we use row operations to find the echelon form of the matrix
We use backward substitution and we obtain
1.
