Answer:
The desired z-score is 2.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
n(12,2.5)
This means that 
z score when x =17
This is Z when X = 17. So
The desired z-score is 2.
Answer:
The correct answer is C
Step-by-step explanation:
Just because we have correlation in a relationship does not mean that we have causation. Therefore, we can not safely say that A or B are true.
Also, it is clearly not D as we have a strong correlation between the two and cannot safely assume that they have nothing to do with one another.
Answer:
C : 4.29
Step-by-step explanation:
First find the distance she walks on the weekdays.
0.55*5=2.75
Now you find out how much she walks on one weekend and multiply that by two.(Saturday and Sunday)
0.55*1.4=0.77
0.77*2=1.54
Now add the two numbers
1.54+2.75=4.29
Hope I helped!!!
Have a great day!
Answer:
so the distance between two points is (2√13)
Step-by-step explanation:
we have to find the distance between two points
d=√(x2-x1)²+(y2-y1)²
putting the values of coordinates
d=√(4--2)²+(-1-3)²
d=√(6)²+(-4)²
d=√36+16
d=√52
d=2√13
i hope this will help you :)
Divide 45 by 3 ( the quantity of consecutive numbers) This will give you the middle number, then use the number higher and lower.
45/3 = 15
14 + 15 + 16 = 45
The 3 numbers are 14, 15 and 16
