What is Geometry?</h3>
Geometry deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area can be found by the sum of all the parts of the figure.
Therefore,
Surface area = 8 + 8 + 12 + 12 + 24 + 24
Surface area = 88
The surface area of the figure will be 88 square feet.

Using the t-distribution, it is found that the 95% confidence interval for the mean number of people the houses were shown is (20.1, 27.9).
We have the <u>standard deviation for the sample</u>, hence the t-distribution is used to build the confidence interval. Important information are given by:
- Sample mean of
. - Sample standard deviation of
. - Sample size of
The confidence interval is:
In which t is the critical value for a <u>95% confidence interval with 23 - 1 = 22 df</u>, thus, looking at a calculator or at the t-table, it is found that t = 2.0739.
Then:
The 95% confidence interval for the mean number of people the houses were shown is (20.1, 27.9).

Answer:
283 or 382
Step-by-step explanation:
The number of children in 1st grade has 3 digits.The digit in the number are 2,3,and 8 .
Since the digit 8 means 80 in the number. The other two numbers could interchange the Hundred and Unit position respectively.
The possible numbers are:
I. 200+80+3=283
II. 300+80+2=382
The possible number of children in 1st Grade is either 283 or 382.

Answer:
$ 22.6
Step-by-step explanation:
Given that
Price charged for each box of seeds = x
Profit gained from from selling boxes of seeds = p
The equation of profit is modeled as
P(x) = 0.5x² + 36x - 179
As per given information if the fundraisers make a profit of $379 then find the minimum price charged for each box of seed.
Now our above equation becomes
379 = -0.5x² + 36x - 179
Simplifying
379+179 = -0.5x² + 36x
558 = -0.5x² + 36x
0.5x² - 36x + 558 =0
multipying both sides of equation by 2
2(0.5x² - 36x + 558) = 2x0
x² - 72x +1116 = 0
Using quadratic formula we get the following factors
x= 49.4 or x= 22.60
As we can the smalles value is 22.6
So, they can charge 22.6 dollar for each bag of seeds in order to get profit of 379 dollars.
