Which number line shows the solution set for |y-9| <12

RUDIKE [14]

Answer:

Option c

$y\geq-3$ or $y \leq 21$

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function $f(x) = |x|$ x> 0 for all real numbers.

Then the inequation:

$|y-9| \leq 12$ has two cases

$(y-9)$ if $y \geq 9$ (i)

$-(y-9)$ if $y < 9$ (ii)

We solve the case (i)

$y \leq 9 + 12\\y\leq21$

We solve the case (ii)

$-y +9 \leq 12\\-y \leq 12-9\\y \geq -3$

Then the solution is:

$y\geq-3$ or $y \leq 21$

In a certain communications system, there is an average of 1 transmission error per 10 seconds. Assume that the distribution of

Nitella [24]

Answer:

The probability of 1 error in a period of 0ne - half minute is 0.1494

Step-by-step explanation:

Formula for poisson distribution:

$P (X = k) = \frac{\exp^{- \lambda} \lambda^{x} }{x!}$

If there is an average of 1 error in 10 seconds

In one-half minutes (i.e. 30 seconds), there will be an average of 30/10 errors = 3 errors

$\lambda = 3 errors\\x = 1$

$P (X = 1) = \frac{\exp^{-3} 3^{1} }{1!}$

1! = 1

$P (X = 1) = 3 \exp^{-3}$

P(X = 1) = 3 * 0.0498

P(X = 1) = 0.01494
