Simplifying

2a + 4b = 0

Solving

2a + 4b = 0

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4b' to each side of the equation.

2a + 4b + -4b = 0 + -4b

Combine like terms: 4b + -4b = 0

2a + 0 = 0 + -4b

2a = 0 + -4b

Remove the zero:

2a = -4b

Divide each side by '2'.

a = -2b

Simplifying

a = -2b

Hope this helps!!!!

Pediatricians work an average of 48 h per week. The standard deviation is 12 hours. What percentage of pediatricians work more t

cricket20 [7]

Answer: 2.28 %

Step-by-step explanation:

Given : Mean : $\mu=\ 48$

Standard deviation : $\sigma= 12$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 72

$z=\dfrac{72-48}{12}=2$

The p-value = $P(2$

$1-0.9772498=0.0227502\approx0.0228$

In percent, $0.0228\times100=2.28\%$

Hence, the percentage of pediatricians work more than 72 h per week = 2.28 %
