I did it on paper just now. Sorry for the sloppy handwriting, but you should be able to answer the two questions with the info I got. If you don't know what five number summary is, just google it.
Basically, arrange the list of numbers in order, and then find the minimum, 1st quartile, median, 3rd quartile, and maximum.
Begin solving like you normally would. Add 2.25 to both sides and subtract 9x from both sides to try getting all x values on one side. However, you will find that after subtracting 9x from both sides, all x values go away, and you end with -2.25=1.6. This is not true (-2.25 is not 1.6), so the answer is no solution. There is no value of x which satisfies that equation.
Answer:
Step-by-step explanation:
First find the slope(m) between (0,-5) and (-5,-6)
m = 
= 
= 
= 
y = x -5
I attached the graph. I used desmos.
Hope that helps!
Answer:
37.75⁰
Step-by-step explanation:
Height of the building = 18 feet (vertical height)
Height of the ladder = 25 feet (Hypotenuse)
We solve this using tan θ = 
therefore θ = tan⁻¹ (
)
θ (Angle of elevation) = 37.75⁰
3. the greatest amount is 3
4. the least amount is 1 4/6
5. 3 + 1 4/6= 4 2/3
6. 3 - 1 4/6= 1 1/3
