n equals 277
9 multiplied by 27 plus 2 multiplied by 31 minus 28 gives n
243 plus 62 minus 28 results in n
305 minus 28 equals n
which means 277 is n
Let
s--------> denote the cube's side length
We know that
the volume of a cube is calculated as

if the side length s measures 
then

and thus, the volume is defined as


This leads us to conclude
the correct option is
D. A cube with side lengths of 2 feet has a volume of 8 cubic feet.
Answer:
The sales figure for the third year is
.
Step-by-step explanation:
Since sales data for the second year is unavailable, we denote it as x million.
Year 3's total sales amount to 32 million.
Calculate the sales account for year 3 as follows:

Response:
a) 
b) From t increasing from 3 to 6, v changes from 18 gallons to 12 gallons.
Detailed explanation:
The relationship between the tank’s volume and time is given by:

Where V(0) indicates the starting volume and a denotes the hourly decrease.
a. Create a formula for v in terms of t.
The tank starts with 24 gallons of water, hence 
It drains steadily at 2 gallons each hour, therefore 
Then


b. When t progresses from 3 to 6, v changes from _________ to _________



So as t progresses from 3 to 6, v shifts from 18 gallons to 12 gallons.
A minimum sample size of 75 is necessary. Step-by-step explanation: We need to determine our level, which is calculated by subtracting 1 from the confidence interval divided by 2. Now, we need to find the z value in the Z table that corresponds to a p-value of [Z value]. Therefore, it is the z value with a p-value of [specific value]. Next, we calculate the margin of error M, where [insert equation], with [standard deviation] representing the population standard deviation and n as the sample size. The standard deviation equals the square root of the variance. With a 0.95 probability level, if the margin of error desired is 5 or below, a sample size of at least 75 is required.
