Unsalted butter in packs are known to be normally distributed. A sample of those packs of butter had masses, measured to the nearest gram, as follows. 219, 226, 217, 224, 223, 216, 229, 225, 229, 221, 228, 215 Find a 956 confidence interval for the mean mass of unsalted packs of butter

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

∞ this is your sign

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the answer is c just got it on ed
