Answer:

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5\}$

$n(S) = 5$

Required

$P(x > 1\ and\ x < 2)$

$P(x > 1\ and\ x < 2)$ is calculated as:

$P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)$

Since it is a probability with replacement, we have:

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

For x > 1, we have:

$x > 1 = \{2,3,4,5\}\\$

$n(x > 1) = 4$

For x < 2, we have:

$x < 2 = \{1\}$

$n(x < 2) = 1$

$P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}$

becomes

$P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}$

$P(x > 1\ and\ x < 2) = \frac{4}{25}$

X+8(x+2) =52 can someone help me pls with these question

ki77a [65]

Answer:

The answer is X=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+8(x+2)=52

x+(8)(x)+(8)(2)=52(Distribute)

x+8x+16=52

(x+8x)+(16)=52(Combine Like Terms)

9x+16=52

Step 2: Subtract 16 from both sides.

9x+16−16=52−16

9x=36

Step 3: Divide both sides by 9.

9x 9 = 36 /9

x=4
