Answer:884 a week, 45,968 a year
Step-by-step explanation:
6800*0.13=884
Answer:
Step-by-step explanation:
<u>Given</u>
<u>8 total balls</u>
- p(r and r) = 5/8*4/7 = 5/14
- p(b and b) = 3/8*2/7= 3/28
<u>Added up</u>
- 5/14 + 3/28 = 10/28 + 3/28 = 13/28
Probability of 2 same colored balls is 13/28
Steps by explanation:
for second one
centroid ={(1+3+5)/3,(2+4+0)/3}=(9/3,6/3)
=(3,2)
Answer:
Option F. 
Step-by-step explanation:
we know that
The solution of the inequality of the graph is the shaded area above the solid line
step 1
Find the equation of the solid line
The intercepts are
The y-intercept is the point (0,b)
The x-intercept is the point (-b,0)
Find the slope
The equation of the solid line is
step 2
The solution of the inequality is the shaded area above the solid line
therefore
the inequality is equal to
If a box has a square base its volume will be:
V=hb^2 where h is the height...
h=V/b^2 we are told that V=125 so
h=125/b^2 now for the surface area, which consists of the two bases for a total of 2b^2. It will also have four sides with a total area of 4(bh)=4bh so
A=2b^2+4bh, using h found above in this gives us:
A=2b^2+4b(V/b^2)
A=2b^2+4V/b
A=(2b^3+4V)/b, then taking the derivatives we can find the velocity of the area function.
dA/db=(6b^3-2b^3-4V)/b^2
dA/db=(4b^3-4V)/b^2
dA/db=0 when 4b^3-4V=0
b^3=V
b=V^(1/3), since V=125
b=5in, and since h=V/b^2
h=125/25=5in
So the dimensions that will minimize the amount of material used to enclose a volume of 125in^2 is a 5in cube.
h=b=5in
