2x+4y=-3 (put 2x on other side)
4y=-3-2x (/ all sides by 4)
y= -3/4 -2/4x (and simplify)
y= -1/2x -3/4

I hope this helped!

alisha [4.7K]

Answer:

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

Step-by-step explanation:

  • Math session = 45 min = 3/4 hr
  • French session = 30 min = 1/2 hr
  • Number of math sessions = m, total math hours = 3/4m
  • Number of French sessions = f, total French hours = 1/2f

<u>Total hours constraint:</u>

  • 3/4m + 1/2f ≤ 30

<u>Number of session constraint:</u>

  • f ≤ 30

<u>So the system is:</u>

  • 3/4m + 1/2f ≤ 30
  • f ≤ 30

In an article about the cost of health care, USA Today reported that a visit to a hospital emergency room has a mean cost of $14
Misha Larkins [42]

Answer: 0.8461

Step-by-step explanation:

Given : \mu=144\ \ ; \sigma=392

Let x be the random variable that represents the cost for the hospital emergency room visit.

We assume that cost for the hospital emergency room visit is normally distributed .

z-score for x=1000 ,

z=\dfrac{1000-1400}{392}\approx-1.02\ \ \ [\because z=\dfrac{x-\mu}{\sigma}]

Using z-value table , we have

P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642

=0.8461358≈0.8461  [Rounded nearest 4 decimal places]

Hence, the probability that the cost will be more than $1000 = 0.8461
