So see if u can factor out the trinomial.
it's factorable.
(x+3)(×-2)

so divide that factors by (×-2)

(×-2)(×+3)
---------
(×-2)

the (×-2) cancel out, leaving x+3

Find the diameter of a sphere with the volume 7776pi in^3

svet-max [94.6K]

Answer:

The diameter is 36 inches

Step-by-step explanation:

The volume of a sphere is

$\frac{4}{3} \pi {r}^{3}$

The given sphere has volume

$7776\pi {in}^{3}$

We can now equate the formula to the given volume and solve for r.

$\frac{4}{3} \pi {r}^{3} = 7776\pi$

${r}^{3}= 7776\pi \times \frac{3}{4\pi}$

${r}^{3} = 5832$

$r = \sqrt[3]{5832}$

$r = 18$

The diameter of the sphere is twice the radius.

Hence

$diameter = 2 \times 18 = 36in$

37 packages are randomly selected from packages received by a parcel service. The sample has a

max2010maxim [7]

True mean = mean+/- Z*(SD/sqrt (n))

Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages

Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
