Answer:
(1,1)
Step-by-step explanation:
5x-2y=1
2x+y=4
Im gonna use substitution but you could also use elimination
2x+y=4
-2x -2x
y=-2x+4
replace y in the first equation with the second equation
5x-2(-2x+4)=1
distribute -2
5x+4x-8=1
add
9x-8=1
+8 +8
9x=9
divide both sides by 9
x=1
then put x in for the equation fo your choice im gonna use the second one
2(1)+y=4
2+y=4
-2 -2
y=1
Hope this helps :))
Diameter is twice the radius. A=πr^2.
First, solve for r:
32.15=πr^2
<em>*Divide both sides by </em>π*
10.2337=r^2
<em>*Take the square root of both sides*</em>
3.199=r
Multiply the radius by 2:
3.199*2=6.398
D. 6.4 feet
Hope this helps!!
You might want to find the IQR, but 23 will most likely be an outlier. Find the mean of all the points except 23 by summing all of the data and then dividing by the number of data points.
Basically add everything except 23 and then divide by seven, then compare that to the mean of all 8 points (which you get by adding everything including 23 and dividing by eight).
