Your volume formula is not correct.
anyway volume = 1/3 * h * r^2*pi, this liquid volume is constant regardless of the container.
so plug in h and r, v = 1/3 * 6 * 3^2 *pi= 18pi
cylinder is just area of circle * h, so
pi*r^2*h = 18 pi
r^2*h= 18
3*3*h=18
h = 2
<span>basically set the volume equal to each other, and plug in r, and solve for H in cylinder eqn</span>
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558
(3.442 ; 6.558)
Answer:
3 vegetable trays, 2 sandwich trays
Step-by-step explanation:
I'm not quite sure what we're supposed to find, but if we were to find how many of each we can buy with $120 it would be 3 vegetable trays and 2 sandwich trays.
20 + 20 + 20 = $60
30 + 30 = $60
60 + 60 = $120
Answer:
y= -2x+0
Step-by-step explanation:
To graph this line you would first want to make an equation that is in slope-intercept form. To do this you will need the equation
(y-y1)=m(x-x1)
y1=you y value
m=slope
x1=your x value
(y-2)= -2(x--1) Since it is x minus negative 1 you can change it to x+1
y-2= -2 (x+1) Now distribute the -2 to both terms inside the parenthesis
y-2= -2(x)-2(1)
y-2= -2x-2 Now add the two from the left to both sides.
+2 +2
y=-2x+0 Now you graph it. Your first point would be (0,0) since your y intercept is 0. From there you just go up two to the left one. Or Down two to the right one.
