First we need to calculate 25% of 120. If 120=100% and X=25% then 120•25=100•X
3000=100X
X=30. Now we know that 25% of 120 is 30.
Now we need to calculate 40% of 120. If 120=100% and y=40%, then 120•40=100y
4800=100y
y=48. Now we know that 40% of 120 is 48.
To find out how many more questions had Riley finished then Annabel, we need to subtract 48 with 30
48-30=18
FINAL ANSWER—18

Hope this helped❤️

Orthogonally diagonalize the matrix, giving an orthogonal matrix P and a diagonal matrix D. To save time, the eigenvalues are

alexgriva [62]

Answer:

$P=\left(\begin{array}{ccc}-\frac{2}{3}&-\frac{2}{3}&\frac{1}{3}\\\frac{1}{\sqrt{5}}&0&\frac{2}{\sqrt{5}}\\-\frac{4}{3\sqrt{5}}&\frac{\sqrt{5}}{3}&\frac{2}{3\sqrt{5}}\end{array}\right)$

Step-by-step explanation:

It is a result that a matrix $A$ is orthogonally diagonalizable if and only if $A$ is a symmetric matrix. According with the data you provided the matrix should be
