Answer: F : $79.99
Step-by-step explanation:
42 x 8 = 339
415.99 - 339 = 79.99
Option (C.) is the correct answer!
Construction of the perpendicular bisector..!!!
<span>There is a 95% chance that the population mean lies between 52.2 liters and 73 liters. This result is obtained by either subtracting the standard deviation from the mean of 62.6 litres or adding it to get the 52.2 or 73 liters.</span>
See the attached figure.
Water model ⇒⇒⇒ y = -0.3 x² + 3x ( blue graph )
Light model ⇒⇒⇒ -2x + 5.5 y = 19.5 ( red graph )
The intersection between the two models A and B
A = ( 1.657 , 4.148 )
B = ( 7.13 , 6.138 )
<span>B is at a higher level than point A
</span>
<span>The distance from the ground level to point A = y-coordinate of point A
= 4.148
</span>
