Eq. of given line is x = -2 》x + 2 = 0
Answer:

Step-by-step explanation:
Given data :
Sample standard deviation, s = 15
Sample mean, 
n = 23
a). 98% confidence interval




∴ 

So, 98% CI is



Father and daguther together
father=180
father and daughter is 7 times daught
father+x=7x
180+x=7x
D is answer
and daughter=30lb
Without using the trigonometry ratio, we can find the distance between the ship and the buoy by:
the distance between City and Lemont SUBTRACT the vertical distance between City and the point parallel to the Ship
The distance between the City and Lemont can be worked out using the Sin rule


≈98.3
The vertical distance between the City and the point parallel to the ship can be worked out using the Pythagoras theorem

≈36.8
The distance between the ship and the Buoy is given:

miles
