A student has an average score of $80$ from her first four Mathematics tests, and $88$ from her first five Physics tests. How much must she score in her upcoming tests to raise her average score in Mathematics and Physics to $82$ and $89,$ respectively?

  1. $92$ in Mathematics and $100$ in Physics.
  2. $86$ in Mathematics and $90$ in Physics.
  3. $88$ in Mathematics and $92$ in Physics.
  4. $90$ in Mathematics and $94$ in Physics.

There are two longest subsequences, not necessarily contiguous, common to the strings $\text{ ARTIFICIAL"}$ and $\text{ INTELLIGENCE."}$ They are $\text{ IIC"}$ and $\text{ TIC"}$ which are of length three. Consider two strings $\text{S1 = CORONAVIRUS"}$ ... $x$ between $\text{S} 1$ and $\text{S} 2$. What is $x+5y?$ $13$ $15$ $14$ $16$

Consider the following code, in which $\text{A}$ is an array indexed from $0.$ function foo (A , n) { m = A [0] ; x = 0 ; for i = 0 to n – 1 { x = x + A [i] ; if (m < x) { m = x ; } if (x < 0) { x = 0 ; } } return (m) ; } If $\text{A}=[-12, -3, 5, 10, 8, -16, -23, 12, -5, 7]$, what will $\textsf{foo(A, 10)}$ return? $23$ $17$ $-17$ $35$
