Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06
1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of 
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
If the height and radius of a cylinder are doubled, the volume of the cylinder will also double or will be higher. This is true because the formula for calculating cylinder’s volume is: V=πr2h; where r is the radius while h is the height. However, as you can see on the formula the radius has more effect than height.
Answer:
(x*2)+6=3
Step-by-step explanation:
I think the answer to that is 1 guest because it said charges guest which means only 1 person is charged
