Answers:
y intercept = -4
slope = -1
==========================================
Explanation:
The given equation is the same as y = -1x + (-4)
Compare this to y = mx+b form, and we see that
m = -1 is the slope
b = -4 is the y intercept
To graph y = -x-4, you could plot the two points (0,-4) and (1,-5) and draw a straight line through them. Extend the line as far as you can in either direction.
Notice how going from (0,-4) to (1,-5) follows the process "down 1, right 1" which is directly pulled from the slope = -1 = -1/1.
Answer: For part I, the probability is 36.69% that the average weight will be less than 234.
To find the percents for each one, you need to find the z-score and use a normal distribution table. A z-score is the number of standard deviations above or below the mean.
For 234, the z-score would be: (234 - 245.7) / 34.5 = -0.34 which corresponds to a percent of 36.69%.
For that last 2 parts, you follow the same plan. However, you will find two different percents. You will have to subtract them to find the percent between them.
For Part II, you should get 6.85%
For Part III, you should get 10.37%.
Answer:The answer is 48
Step-by-step explanation:
The x-coordinate of the vertex represents the LOWEST horizontal DISTANCE from the left side of the ride.
Answer:
P(Hispanic or Bilingual) = 0.429.
Step-by-step explanation:
This question is solved treating these events as Venn probabilities.
I am going to say that:
Event A: Hispanic
Event B: Bilingual
Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:
This means that:

What is the probability that teacher is Hispanic or bilingual?
This is:

With the values that the exercise gives us:

So
P(Hispanic or Bilingual) = 0.429.
