premier bank is planning to have a new building constructed
Answers
Let L, W, N represent the length in feet, width in feet, and number of floors (count). Then it seems we can write
.. L = W +40 . . . . . length is 40 ft more than width
.. 10LW +35000N = 1180000 . . . . . cost is based on foundation area and number of floors. (Here, we assume the 1st floor is sandwiched between the foundation at ground level and whatever it is that is 12 ft high and costs 35,000.)
.. 2(L +W) = 3*(12N) . . . . the height is 12 ft times the number of floors, and the perimeter is 3 times that.
These give rise to a quadratic equation.
.. 10L(L -40) +35000(L +(L -40))/18 = 1180000
Eliminating fractions and dividing by 10, we get
.. 9L^2 +3140L -1132000 = 0
The positive solution is

Answers
The student's question involves understanding and completing a two-factor ANOVA table in statistics, which is used to determine if there are significant differences between group means.
Explanation:The question involves an Analysis of Variance (ANOVA) table used in statistics to test if there are significant differences between the means of three or more independent groups. Given the degrees of freedom (df), sum of squares (SS), and mean squares (MS), one would typically calculate the F-statistic for each source of variance (Factor A, Factor B, and the interaction) by dividing the MS of that source by the error MS. If the calculated F-statistic is greater than the critical F-value from the F-distribution table, one can reject the null hypothesis that the group means are equal. ANOVA is used in various research fields where data needs to be compared across multiple groups or factors.

Answers
Answer: The net price to the nearest cent is $23.80.
Step-by-step explanation:
Since we have given that
List price of a bicycle = $28
Rate of trade discount = 15%
So, Amount of trade discount would be
[tex]\dfrac{15}{100}\times 28\\\\=\$4.20[/tex]

Does the following equation represent growth or decay y=76(1.013)x
Answers
Answer:
[tex]y=76(1.013)^x[/tex]
Growth
Step-by-step explanation:
We are given an equation [tex]y=76(1.013)^x[/tex]
We need to say about growth or decay of above equation.
It is an exponential function.
[tex]y=ab^x[/tex]
Growth or decay depends on the value of b
If b>1 then function is growth
If 0<b<a then function is decay
Now, we compare the the function
[tex]76(1.013)^x\rightarrow ab^x[/tex]
[tex]b=1.013[/tex]
b>1
The value of b is greater than 1.
Hence, [tex]y=76(1.013)^x[/tex] is growth function.
A website randomly creates an initial password for people when they first sign up for an account. The password consists of five letters, and cannot include numbers or special characters. The letters of the password cannot repeat. What is the approximate probability that a password will have no vowels? What is the approximate probability that the first letter of the password will be m?
Answers
No vowels
The question actually starts right here. The preamble tells us that we can only use letters, no numbers, and no symbols. We are not asked to do anything. The first question makes no mention of there being anything special about m. It can be there or it most likely is not. This part of the problem is the first part.
First Part
I'm not going to deal with y. I will declare it to be a consonant.
There are 5 vowels. None of them can be chosen.
21 letters remain (including the m since it has not been limited in any way yet).
21 * 20 * 19 * 18 * 17
================
26 * 25 * 24 * 23 * 22
2441880 / 7893600
0.30934
Note: If your calculator has nPr on it, you can enter 21 nPr 5 to eliminate all the typing.
Second Part
No vowels and the first letter MUST be m
1 * 20 * 19 * 18 * 17/( 26 * 25 * 24 * 23 * 22)
116200/7893600 = 0.01473
Vowels and the first letter m.
1 * 25 * 24 * 23 * 22/ 7893600 = 0.03846
Wyatt is hiking a trail that is 11/12 mile long. After hiking 1/4 Mile he stops for water. How much farther must he hike to finish the trail?
Answers
stop = 1/4 mile
d_remaining = ?????
d_remaining =d - stop
d_remaining = 11/12 - 1/4
1/4 = 1*3 / 4*3 = 3/12 You are doing this so that 1/4 has the same denominator as 11/12
d_remaining = 11/12 - 3/12 = 8/12
Wyatt has 8/12 of a mile to go 8/12 = 2/3 of a mile to go
2/3 mile <<<<<==== Answer.
You could also do this as a decimal
11/12 = 11 divide by 12 = 0.91666666667
1/4 = 0.25
Remainder = 0.9166666667 - 0.25
Remainder = 0.6666666 which is 2/3
I have not been particularly careful about how many 6s you get. Just copy what your calculator says..
Final answer:
Wyatt has 2/3 mile left to hike to finish the 11/12 mile long trail after stopping for water having hiked 1/4 mile.
Explanation:
Wyatt is hiking a trail that is 11/12 mile long, and after hiking 1/4 mile, he stops for water. To calculate how much farther he must hike to finish the trail, we subtract the distance he has already hiked from the total length of the trail.
The calculation would be:
Total trail length - Distance already hiked = Distance remaining
(11/12) - (1/4) = (11/12) - (3/12) = (8/12) miles
After simplifying the fraction, we find that Wyatt has 2/3 mile left to hike to reach the end of the trail.
“You are collecting email addresses from 74 customers per day, which is about 90% of the daily goal of emails per day.”
Answers
74 = 0.90x , where x is the daily goal of emails per day.
Dividing both sides by 0.90 gives x = 82.222. We can round down to 82 emails.
Final answer:
To find the daily email goal when 74 is 90%, we divide 74 by 0.9, leading to approximately 82.22 emails. The importance of email is underscored by the billions of users and emails sent daily, highlighting its role in business communication.
Explanation:
The student's question pertains to the calculation of a daily email collection goal based on the collection of email addresses from 74 customers, which they've stated is 90% of that goal.
To find the total daily goal, we can set up a proportion where 90% (or 0.9) of the goal equals 74 customers. We use a simple algebraic equation to solve for the total goal (G): 0.9 * G = 74. Dividing both sides by 0.9 gives us G = 74 / 0.9, which gives us the total goal as approximately 82.22 customers per day.
It's important to understand the context and relevance of emails in our daily lives. As of 2023, there are over 4.2 billion email users globally with up to 60 billion emails sent daily.
This vast number shows the significance of email communication, especially in business communication, making it a fundamental skill to manage effectively. With an average office worker receiving 120 emails daily, it becomes clear why being effective with email correspondence is crucial.
Your family vacation involves a cross-country air flight, a rental car, and a hotel stay in boston. if you can choose from three major air carriers, two car rental agencies, and five major hotel chains, how many options are available for your vacation accommodations?
Answers
Final answer:
To find the total number of vacation accommodation options, multiply the choices of air carriers (3), car rental agencies (2), and hotel chains (5) together, resulting in 30 different combinations.
Explanation:
The question involves calculating the total number of vacation accommodation options available given a set of choices for air carriers, car rental agencies, and hotels. This type of problem is a basic combinatorial problem that requires multiplying the number of possibilities for each choice to get the total number of combinations.
To solve this, we can use the fundamental counting principle which states that if there are n ways to do one thing, and m ways to do another, then there are n x m ways to do both.
Applying this principle:
Number of air carriers: 3Number of car rental agencies: 2Number of hotel chains: 5We multiply these together: 3 x 2 x 5 = 30 total options for the vacation accommodations.

The ratio of the perimeters of two similar triangles is 3:7. Find the ration of the areas! Please help, I am really not sure. And please explain well in terms that I can understand and draw a visual as well.
Answers
Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.
Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.

y < 3x + 2
y > 3x + 2
y < x + 2
y > x + 2
Answers
Answer:
y > 3x+2
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/(x2-x1)
= (2--7)/(0--3)
= (2+7)/(0+3)
= 9/3
= 3
The y intercept is 2, so we can write the equation of the line using the slope intercept form (y=mx+b)
y = 3x+2
The line is dotted so we use either < or > (If it were solid we would use ≤ or ≥)
Since it is shaded above , y is greater than.
y > 3x+2

find the volume of the cylinder 13mm and 16mm
Answers
The volume of the cylinder is approximately 8491 mm³.
To find the volume of a cylinder, we use the formula:
[tex]\[ \text{Volume} = \pi \times \text{radius}^2 \times \text{height} \][/tex]
Given:
Radius [tex](\( r \))[/tex] = 13 mm
Height [tex](\( h \))[/tex] = 16 mm
Substitute the values into the formula:
[tex]\[ \text{Volume} = \pi \times (13)^2 \times 16 \][/tex]
[tex]\[ \text{Volume} = \pi \times 169 \times 16 \][/tex]
[tex]\[ \text{Volume} = \pi \times 2704 \][/tex]
Using an approximate value of [tex]\( \pi \)[/tex] as 3.14:
[tex]\[ \text{Volume} \approx 3.14 \times 2704 \][/tex]
[tex]\[ \text{Volume} \approx 8491.36 \, \text{mm}^3 \][/tex]
Rounded to the nearest whole number, the volume is approximately 8491 mm³, which matches option B. Therefore, the correct answer is B.
