Answer:
z-score for value 560 = 0.6
z-score for value 650 = 1.5
z-score for value 500 = 0
z-score for value 450 = -0.5
z-score for value 300 = -2
Step-by-step explanation:
We are given a sample with a mean of 500 and a standard deviation of 100.
i.e., = 500 and
= 100
The z score distribution is given by;
Z = ~ N(0,1)
where X represents the data values;
- So, z score for value 560 is;
z score = = 0.6
- So, z score for value 650 is;
z score = = 1.5
- So, z score for value 500 is;
z score = = 0
- So, z score for value 450 is;
z score = = -0.5
- So, z score for value 300 is;
z score = = -2
Answer:
Please see the attachment for double number line.
Explanation:
We are given cost of 4 water bottles is $10
We can write ,
Cost of 4 bottles = $10
Cost of 1 bottle = $2.5
Cost of 2 bottles =$5
Cost of 3 bottles = = $7.5
Cost of n bottles = $2.5n
Now we draw the double number line.
Bottom line(Line 1) will take as number of bottles:
1 2 3 4 5 6
Above line (Line 2) will show the cost of corresponding number of bottles:
2.5 5 7.5 10 12.5 15
