(Look at the pic) what is FC?

Hitman42 [59]

The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.

Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):

$-2\cdot 12+0\cdot 1 = -24+0=-24$

The only matrix that has a value of -24 in the position (1,1) is matrix B.

Therefore, the answer is matrix B.

Zara has forgotten her 4-digit PIN code. She knows the first digit is a prime number and the 4 digits make a number divisible by

vredina [299]

Answer:

2,500 different sets

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Let 4-digit PIN code be WXYZ

As first digit is a prime number

So, W = 1, 2, 3, 5, 7

n(W) = 5

X and Y are number from 0 - 9

So, n(X) = 10 & n(Y) = 10

Z makes the whole number divisible by 2.

So, Z must even number

So, Z = 0,2,4,6,8 or n(Z) = 5

We can calculate the number of different sets by using following formula,

n(W) × n(X) × n(Y) × n(Z)

By putting the value, we get

5 × 10 × 10 × 5 = 2,500
