Solve for x

ludmilkaskok [199]

Answer:

x = 3/4

Step-by-step explanation:

Step 1: Write equation

5x - 2(x + 1) = 1/4

Step 2: Solve for x

Distribute -2: 5x - 2x - 2 = 1/4
Combine like terms: 3x - 2 = 1/4
Add 2 to both sides: 3x = 9/4
Divide both sides by 3: x = 3/4

Step 3: Check

Plug in x to verify it's a solution.

5(3/4) - 2(3/4 + 1) = 1/4

15/4 - 2(7/4) = 1/4

15/4 - 14/4 = 1/4

1/4 = 1/4

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with an average weight of 5

Lisa [10]

Answer: 0.4987

Step-by-step explanation:

Given : The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with

Mean : $\mu=5\text { lbs}$

Standard deviation : $\sigma= 2\text{ lbs}$

Let X be the random variable that represents the weight of randomly selected student .

Z score : $z=\dfrac{x-\mu}{\sigma}$

For x = 5 lbs

$z=\dfrac{5-5}{2}=0$

For x = 11 lbs

$z=\dfrac{11-5}{2}=3$

By using the standard normal distribution table , the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs :-

$P(5$

Hence, the probability that the weight of the newborn baby boy will be between 5 lbs and 11 lbs =0.4987
