To find the area of a square, <em>we multiply the length by its width </em>

In this case, the length and width of the square area are both 9!

We know this becasue it says "<u>each side of a square piece of cardboard is 9 inches long" </u>

Now let's solve the problem

Area = L × W

Area = 9inches × 9inches

Area = 81 inches²

*I put the "²" above inches because any area of a square is just multiplying the same number by itself or ... in other words... "squaring it"

[ex: 9² = 9 × 9]

HELLLPPPPPPP .... The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no

Dominik [7]

Answer:

P(I⋂D)

Step-by-step explanation:

The symbolic way to represent the probability of a true positive is P(I⋂D).

We know that I stands for Infected, U stands for Uninfected, D for Infection detected, N for infection no detected.

Then, a true positive will be given by the intersection of Infected and Infection Detected.
