Here zά/2= z0.05/2= 1.96
Substitute the values we have
654.16 ± 1.96 x 164.43/âš41

Answer: (-2, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the <em>x</em> and <em>y</em> that is the solution to this system of equations.
The two lines intersect in quadrant III
where <em>x</em> and <em>y</em> are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 2 and down 1 so that's (-2, -1).
So the solution to this system is (-2, -1).
Answer:
0.0176 (round the 5 up to 6 because of the 8)
Answer:
A. 2nd avenue
Step-by-step explanation:
There is a 90 degree angle between Maple Street and 2nd Ave., so therefore it is perpendicular
Answer:
13,200 feet
Step-by-step explanation:
Each mile is 5280 feet, times that by 2.5, you get 13,200
