your bakery is in a large shopping center. The entrie shopping center is 4,500 square feet. Your bakery takes up only 1/10 of that space.How many square feet is your bakery
The bakery takes up 1/10 of the total shopping center space. Since the shopping center is 4,500 square feet, the bakery is 450 square feet.
To determine the size of the bakery in square feet, we need to calculate 1/10th of the total shopping center's area. The shopping center is 4,500 square feet in total. So, the calculation would be:
Divide the total area by 10 to find 1/10 of the area.Multiply that number by 1 to get the exact area for the bakery.Here's the step-by-step calculation:
4,500 square feet / 10 = 450 square feetTherefore, the bakery takes up 450 square feet of space within the shopping center.

Which graph represents the solution set of the system of inequalities?
In calculating one variable statistics you find the standard deviation to be equal to zero
A standard deviation of zero in a data set signifies that all data points are identical, with no variation among them.
When calculating one variable statistics, if you find that the standard deviation is equal to zero, it means that all of the data points in the set have the same value. There is no spread or variability within the data, as standard deviation measures how much each number in a set differs from the mean of the data set. Since all numbers are the same, they all equal the mean, resulting in zero deviation.

The base of a pyramid has n sides.
Write an EXPRESSION for the number of faces of the pyramid.
Answer: The expression for number of faces of a pyramid =1+n
Step-by-step explanation:
A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .
Its base describe the number of other faces of it.
For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....
So the total number of faces in a pyramid = base + lateral faces
If a pyramid has n sides therefore it give rise to n lateral faces such that
The total number of faces in a pyramid= 1+n .
The total number of faces of the pyramid is [tex]n+1[/tex].
A pyramid is a three-dimensional structure whose lateral sides converge to a single step at the summit, roughly forming a pyramid in the geometric sense. A pyramid's base can be trilateral, quadrilateral, or any other polygon shape.
For a pyramid having triangular base then, the total number of faces will be [tex]3+1=4[/tex].
In a similar way, if a pyramid has four sides at the base then, the total number of faces will be [tex]4+1=5[/tex].
Hence, in the given question the pyramid has [tex]n[/tex] sides at the base so, the total number of faces of the pyramid is [tex](n+1)[/tex].

The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard deviation of 2.2 minutes. how long do the longest 10% of calls last?
To solve this problem, we use the formula:
z = (x – u) / s
where z is the z score value which can be obtained from the tables, x is the sample value, u is the mean = 6.3 min, and s is the std dev = 2.2 min
at P value = 0.90, the z = 1.28, finding for x:
x = z s + u
x = 1.28 * 2.2 + 6.3
x = 9.116
at P value = 1.0, the z = 3.49, finding for x:
x = z s + u
x = 3.49 * 2.2 + 6.3
x = 13.978 ~ 14
Therefore the longest 10% calls last about 9.1 minutes to 14 minutes

A veterinarian estimated the weight of a puppy to be 9kg. The actual weight of the puppy was 9.5kg Find the absolute error and the percent error of the veterinarian's estimate. If necessary, round your answers to the nearest tenth.
Answer:
That huy is wrong... the answer is negetive! People
Step-by-step explanation:
The absolute error of the veterinarian's estimate is 0.5 kg, and the percent error is approximately 5.3% when rounded to the nearest tenth.
The question given asks us to find the absolute error and the percent error of a veterinarian's estimate of a puppy's weight. To calculate the absolute error, we take the actual weight of the puppy (9.5 kg) and subtract the veterinarian's estimate (9 kg), which gives us an absolute error of 0.5 kg. To find the percent error, we divide the absolute error by the actual weight and multiply by 100, resulting in a percent error of about 5.3% when rounded to the nearest tenth.
Here is the step-by-step breakdown:
Calculate absolute error: Actual weight - Estimated weight = 9.5kg - 9kg = 0.5kgCalculate percent error: (Absolute error / Actual weight) * 100 = (0.5kg / 9.5kg) * 100 ≈ 5.263%. Round this to the nearest tenth: 5.3%which regular polygon has a minimum rotation of 45 to carry the polygon onto itself
Which functions represent the arithmetic sequence 8, 1.5, –5, –11.5 . . . ? Check all that apply.
f(n) = –6.5n + 14.5f(n) = –1.5n + 9.5f(n) = 6.5n + 1.5f(1) = 8, f(n + 1) = f(n) – 6.5f(1) = 8, f(n + 1) = f(n) – 1.5f(1) = 8, f(n + 1) = f(n) + 6.5
Answer:
f(n)= -6.5n +14.5
f(1)= 8, f(n+1) = f(n) - 6.5
Step-by-step explanation:
the arithmetic sequence 8, 1.5, –5, –11.5 . . .
First term is 8
Now we find difference between the terms
1.5 - 8= -6.5
-5-1.5= -6.5
difference is -6.5
The formula is f(n)= a1 + (n-1)d
where a1 is the first term and d is the difference
f(n)= 8 + (n-1)(-6.5)
f(n)= 8 -6.5n+6.5
f(n)= -6.5n +14.5
To get recursive formula we use
f(n+1) = f(n)+ difference
f(1)= 8, f(n+1) = f(n) - 6.5
The functions that represent the arithmetic sequence is given by:
f(n) = –6.5n + 14.5
f(n+1) f(n) – 6.5, f(1) = 8
------------------
In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d, and the nth term is given by:
[tex]f(n) = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.The sequence can also be represented by a recursive sequence, given by:
[tex]f(1) = a_1[/tex]
[tex]f(n+1) = f(n) - d[/tex]
In this sequence:
The first term is [tex]a_1 = -[/tex]The common difference is [tex]d = 1.5 - 8 = -6.5[/tex].Thus, the possible representations are:
[tex]f(n) = a_1 + (n-1)d[/tex]
[tex]f(n) = 8 - 6.5(n-1)[/tex]
[tex]f(n) = 8 - 6.5n + 6.5[/tex]
[tex]f(n) = -6.5n + 14.5[/tex]
And
[tex]f(1) = a_1[/tex]
[tex]f(n+1) = f(n) - d[/tex]
[tex]f(1) = 8[/tex]
[tex]f(n+1) = f(n) - 6.5[/tex]

Vail Ski Shop received a $1,201 invoice dated July 8 with 2/10, 1/15, n/60 terms. On July 22, Vail sent a $485 partial payment. (If more than one discount, assume date of last discount)
a. What credit should Vail receive?
b. What is Vail’s outstanding balance?
Vail Ski Shop won't receive any credit because the payment did exceed the discount period. Vail's outstanding balance is $716, calculated by subtracting the partial payment from the original invoice.
Explanation:The $1,201 invoice dated July 8 with 2/10, 1/15, n/60 terms means that Vail Ski Shop receives a discount if paid within certain time periods, specifically a 2% discount if paid within 10 days, a 1% discount if paid within 15 days, and full payment is required within 60 days. However, since Vail made a partial payment of $485 on July 22, the days had already exceeded both the 10 and 15-day discount periods. This implies that Vail should not receive any credit.
To calculate Vail's outstanding balance, we would subtract the amount Vail has paid partially from the original invoice. So, the calculation would be $1,201 - $485 which equals $716. Therefore, Vail's outstanding balance would be $716.
