Something is missing in right hand side
The plot for January places the median age at 40, so half of the surveyed group was over 40. That would be half of 100 people, or 50 people.
The plot for July places the upper quartile at age 40, so 1/4 of the surveyed group was over 40. That would be 1/4 of 100 people, or 25 people.
There were 50 - 25 = 25 more visitors over the age of 40 at the beach in January.
So then whats the question? What do you need to find out?
Answer:
y = -2x - 1
Step-by-step explanation:
Parallel lines have the same slope, so the slope will also be -2.
Plug this slope and the given point into the equation y = mx + b and solve for b:
y = mx + b
5 = -2(-3) + b
5 = 6 + b
-1 = b
Then, plug this and the slope into the equation:
y = -2x -1 will be the equation
Answer:
Option D.
Step-by-step explanation:
The angle of elevation of an object is the angle between the horizontal line and the line from the object to the eye of the observer.
The angle of depression is the downwards angle between the horizontal line and the line from the eye of the observer to the object.
We know that sine angle is given by side opposite to the angle divided by the hypotenuse.
