Answer:

0.5160

Step-by-step explanation:

Xi:"i-th Signal"

Xi=1, False alarm

Xi=0, True error

$Y=\sum ^{10}_{i=1}Xi$

X=Ber(p=0.07)

Y=Bin(n=10, p=0.07)

$P(\displaystyle\sum_{i=1}^{10} X_i\geq 1)=1-P(\displaystyle\sum_{i=1}^{10} X_i=0)=1-P(Y=0)=1-(1-0.07)^{10}=0.5160$

Which pair shows equivalent expressions? 3 (x + 2) = 3 x + 6 3 x + 2 x = x squared (3 + 2) 3 x + 2 = 3 (x + 2) Negative 3 (2 + x

kogti [31]

Answer:

The first pair shows equivalent expressions.

Step-by-step explanation:

3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6

The first equation is 3(x+2)=3x+6

Therefore, the first pair shows equivalent expressions.
