The z-score of a person who scored 292 on the exam is 2.30

<h3>How to determine the z-score?</h3>

The given parameters are:

  • Scores are normally distributed
  • Mean of 200
  • Standard deviation of 40

The z-score of a person who scored 292 on the exam is calculated as:

z = Score - mean/Standard deviation

So, we have

z = 292 - 200/40

Evaluate the difference

z = 92/40

Divide

z = 2.30

Hence, the z-score of a person who scored 292 on the exam is 2.30

What Is The Rate Of Change In This Function?
Marrrta [24]

Answer:The answer would be 35 miles per day.

Step-by-step explanation:

We know the x axis is in days and the y axis is the distance in miles. There are only three answers left. We can also cross out 50 miles per day since the  rate of change is less then 50. The answer is 35 miles per day because if the rate of change were to be 25 in 4 days the distance would be 100 miles, while is you look at where the point is at it is closer to 150.

A liquid has a oh of 7.4, find the hydrogen ion concentration [H+]?
Radda [10]
<span>pHProblem 4- Determine the hydrogen concentration of bloodTutorial to help you with this calculation.<span>4.What is the approximate hydrogen ion concentration of blood with pH 7.4?</span><span> <span><span>TutorialIn this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,− pH = log [H+] ,[H+] = 10−pH,by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M. </span></span></span></span>

A) What equation is used to find the vertex form of a parabola with the vertex (h, k)?
VikaD [51]
Y=ax2+bx+c . In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .
