Answer:
Using calculator: 0.0415
Using Z-score Table: 0.0418
Step-by-step explanation:
There are two ways you can solve this problem.
1. Use the normal distribution function on a calculator.
Entered values:
Lower Limit: 126
Upper Limit: 999999999999999... (To encompass all the data)
Standard Deviation: 15
Mean: 100
2. Find the Z score and look up probabilities on table.
Formula for Z score:

Z = 1.7333
This means that the value 126 is 1.733 standard deviations away from the mean. We can look this value up on the Z table to find its corresponding probability.
This will show us the probability of the random sampling being equal to or lower than 126.
P = 0.9582
So to find the probability of it being above, we simply just calculate the inverse as all probabilities on the curve = 1.
1-0.9582 = 0.0418
NOTE: Values found from the table will usually be a bit different from if you find it from a calculator, the one you need will depend on the method you use in class.
Hope this helped!
Answer:
The slope is m=0
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.If y-coordinates are equal and x-coordinates are not equal (as in our case), then the slope equals 00 (the line is horizontal).
<h3>Total cost of their lunch, including the tip is $ 27.6</h3>
<em><u>Solution:</u></em>
The cost for Dana and Courtney's lunch is $24
They want to leave a 15% tip
To find: total cost of their lunch, including the tip
<em><u>Find the tip amount</u></em>
Tip amount = 15 % of 24

<em><u>what is the total cost of their lunch, including the tip?</u></em>
Total cost = cost of lunch + tip amount
Total cost = 24 + 3.6
Total cost = 27.6
Thus total cost of their lunch, including the tip is $ 27.6
