Slope = -1/2
y-intercept = 6
<3
Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall
6.5 + 4.5 = 11
6.5 - 4.5 = 2
So 2 to 11 ounces would be the interval
Answer:
Each would pay $20.94
Step-by-step explanation:
Step 1: Find the total for the bill including the tip.
The bill is $52.35. To calculate 20% of this, multiply by 0.2 (or 20/100)
The tip is ($52.35)(0.2) = $10.47
Step 2: Add the tip to the total bill.
$52.35 + $10.47 = $62.82
Step 3: Divide the total bill by the number of people splitting the bill, in this case, 3
$62.82/3 = $20.94 per person
15+26s-6=25s-9
26s+9=25s-9
s+9=-9
s=-18
