Step-by-step explanation:
(a) A histogram is like a bar graph, but with ranges instead of values.
(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.
(c) The ages do not appear to come from a normal distribution. Normal distributions are bell-shaped, tall in the middle and short on the sides.
Answer:
If you solve by substitution then the answer for the first one would be (−7,−7) or x=−7,y=−7 and the second has no solution
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Please tell me if this is right
Circles!!!
The general formula is:
x^2 + y^2 = r^2
where x and y form the circle while r is the radius.
You already have the problem set up in its general form and you don't want the radius squared... so square root everything.
If you do that then you'll get:
x + y = 5
where 5 is the radius and NOT the radius squared. If you have questions then leave a comment. Good luck!
2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
