Answer:
#4: Blank 1: 4x, Blank 2: 3; #5: A) or D)
Step-by-step explanation:
Question 4: 4x, 3
- Divide using the rules of synthetic divison (see Khan Academy)
- Blank 1: 4x
- Blank 2: 3
Question 5: A) or D)
- B) and C) are automatically out- they have the wrong notation
- It's either A) or D) - don't know for sure
The answer is 41 , this is because the angles have to add up to 180 in total therefore 180-139 = 41
Answer:
a) P(X<50)=0.9827
b) P(X>47)=0.4321
c) P(-1.5<z<1.5)=0.8664
Step-by-step explanation:
We will calculate the probability based on a random sample of one moped out of the population, normally distributed with mean 46.7 and standard deviation 1.75.
a) This means we have to calculate P(x<50).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:

b) We have to calculatee P(x>47).
We will calculate the z-score and then calculate the probability accordign to the standard normal distribution:

c) If the value differs 1.5 standard deviations from the mean value, we have a z-score of z=1.5

So the probability that maximum speed differs from the mean value by at most 1.5 standard deviations is P(-1.5<z<1.5):

Your answer is d Its on the fourth quadrant! that Is really easy!
