Answer:
width = 1.8 in
length = 3.6 in
height =
Step-by-step explanation:
A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in
Let l , w and h are the length , width and height

Plug it in the first equation

volume the box is length times width times height

To get maximum volume we take derivatived

set the derivative =0 and solve for w

width = 1.8 in
length = 2w= 3.6 in
height =
Answer:
x²(9x– 11)(9x + 11)
Step-by-step explanation:
81x⁴ – 121x²
The expression can be factorised as follow:
81x⁴ – 121x²
x² is common to both term. Thus:
81x⁴ – 121x² = x²(81x² – 121)
Recall:
81 = 9²
121 = 11²
Therefore,
x²(81x² – 121) = x²(9²x² – 11²)
= x²[(9x)² – 11²]
Difference of two squares
x²(9x– 11)(9x + 11)
Therefore,
81x⁴ – 121x² = x²(9x– 11)(9x + 11)
Answer:
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means
and we don't have enough evidence to conclude that the two population variances and deviations are different.
Step-by-step explanation:
System of hypothesis
We want to test if the variation for a group1 is equal to another one 2, so the system of hypothesis are:
H0:
H1:
Calculate the statistic
The statistic for this system of hypothesis is given by:
If the statistic is equal to 1 then that means
and we don't have enough evidence to conclude that the two population variances and deviations are different.
