minutes can be rented for $26
(Round to the nearest minute as needed)
A linear model
reasonable for this situation
Answer:
(A) The independent variable is time (t) in minutes, and the dependent variable is rental cost (), in dollars. The linear function that models this situation is
R(t) = 30t +8
The time that can be rented for $26 = 1min
Step-by-step explanation:
Based on the information given:
Setup charge on Rent at local copy center = $9
an additional $150 for every 5 minutes. To determine the time that can be rented for $26, let's find the relationship between the rental cost and the time.
For every 5min = $150
For 1 min = $150/5
For t min = 150t/5
Where t = number of minutes of rental time
Rental cost = set up charge + additional cost
Let Rental cost = R(t)
R(t) = 9 + 150t/5
Writing it in form of a linear equation: y = mx + c
R(t) = 150t/5 +9
R(t) = (150/5) ×t + 9
R(t) = 30t + 9
The independent variable is time (t) in minutes, and the dependent variable is rental cost (), in dollars. The linear function that models this situation is
R(t) = 30t + 9
The time that can be rented for $26:
Rental cost = $26
R(t) = 30t +9
26 = 30t +9
26-9 = 30t
17 = 30t
t = 17/30 = 0.57
t is approximately = 1min (nearest minute)
The time that can be rented for $26 = 1min

are the vectors 1 1 3 , −1 2 eπ , 2√5 0 , 727 6 99 , −π 5 −7√3 linearly dependent? why?
The value of a = b = c = 0. So v₁, v₂ and v₃ are linearly independent.
The vectors are v₁ = (2, 5, 3), v₂ = (1, 1, 1), and v₃ = (4, −2, 0).
av₁ + bv₂ + cv₃ = 0
a(2, 5, 3) + b(1, 1, 1) + c(4, −2, 0) = (0, 0, 0)
(2a, 5a, 3a) + (b, b, b) + (4c, −2c, 0) = (0, 0, 0)
(2a + b + 4c, 5a + b - 2c, 3a + b + 0) = (0, 0, 0)
(2a + b + 4c, 5a + b - 2c, 3a + b) = (0, 0, 0)
2a + b + 4c = 0....................(1)
5a + b - 2c = 0....................(2)
3a + b = 0....................(3)
From the equation 3; b = -3a
Now put the value of b in equation 1 and 2
2a - 3a + 4c = 0
-a + 4c = 0....................(4)
2a - 2c = 0
a - c = 0....................(5)
Adding equation 4 and 5
3c = 0
c = 0
Now put the value of c in equation 5;
a = 0
Now put the value of a in value of b;
b = 0
Since, a = b = c = 0. So v₁, v₂ and v₃ are linearly independent.

Answer:

Step-by-step explanation:
write an expression that will select all the words of at least five letters from a list. for example, if the words in the list are being, for, the, benefit, of, mister, and kite, then your block should choose the words being, benefit, and mister.
To write an expression that selects all words with at least five letters from a list, you can use a list comprehension in Python and that are word, list, filtered, for, kite.
List comprehensions provide a concise way to create new lists by filtering or modifying elements from an existing list.
Here's an example using the words you provided:
```python
words_list = ['being', 'for', 'the', 'benefit', 'of', 'mister', 'and', 'kite']
filtered_words = [word for word in words_list if len(word) >= 5]
```
In this example, the list comprehension iterates through each word in `words_list` and checks if its length (`len(word)`) is greater than or equal to 5. If the condition is met, the word is added to the new `filtered_words` list. The result will be `['being', 'benefit', 'mister']`, which are the words with at least five letters in the original list.

Answer:
x-coordinates are the same
Step-by-step explanation:
the mean number of runs scored before the 4th innings was 10 less than the mean number scored for the 4th innings. how many runs were scored in the 4th innings if he scored 80,70 and 60 runs in his first three innings
A total of 110 runs were scored in the fourth innings such that the mean is lower by 10 runs.
The runs scored in the first three innings are 60,70 and 80
Total runs scored in the first three innings = 60+70 + 80 = 210
Mean of the runs scored = 210 / 3 = 70 runs
Now the fourth innings let the batsman scored x runs.
Total runs scored in all 4 innings = 210 + x
Mean of all 4 innings = (210 +x) / 4
Now the new mean is 10 more than the old mean.
Hence, (210 + x) / 4 = 70+10
or, 210 + x = 320
or, x= 110
Hence he scored 110 runs in the fourth innings .
The mean is one of the most important and widely used measures of central tendency. There are numerous different types of means in mathematics.
The mean in statistics is calculated by multiplying all the values in a set of data by the total number of values in the data, usually for a specific set of observations.

a circular field has area 14400 square feet what is the radius? a 12ft b 120ft c 720ft d 7200ft
The radius of the circular field with area 14400 square feet is 67.7ft
What is a circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
The radius of a circular field with an area of 14400 square feet can be calculated by the formula:
Area of a circle(A) = \(\pi r^{2}\)
where A = 14400\(ft^{2}\)
\(\pi\) = constant which is 3.142
A = \(\pi\)\(r^{2}\), where A = area of circle , r = radius
divide both sides by c
A/\(\pi\) = \(r^{2}\)
\(r^{2}\) = A/\(\pi\)
r = \(\sqrt{\frac{A}{\pi } }\)
Substitute the values of A and \(\pi\)
r = \(\sqrt{\frac{14400}{3.142} }\)
r = 67.7ft
In conclusion the radius of the field is 67.7ft

1. consider a lottery with three possible outcomes: $125 will be received with probability 0.25, $100 will be received with probability 0.3 and $50 will be received with probability 0.45. a. what is the expected value of the lottery? b. what is the variance of the outcome? c. what would a risk-neutral person pay (at most) to play the lottery?
The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975

Emily is considering upgrading to a larger hot tub. The current hot tub has a cylindrical shape. If the new tub has the same cylindrical shape, with a radius that is twice as large and a height that is 20 % taller, how much greater is the volume of the bigger tub?
If the new tub has the same cylindrical shape, with a radius that is twice as large and a height that is 20 % taller, then the volume of bigger tub is 3.8 times greater.
The volume of a cylinder is given by the formula:
V = πr^2h
where V is the volume, r is the radius, and h is the height of the cylinder.
Let the current hot tub have radius r and height h, so its volume is:
V1 = πr^2h
The new hot tub has a radius that is twice as large, which means the new radius is 2r. The height is 20% taller than the current height, which means the new height is (1 + 0.2)h = 1.2h. So, the volume of the new hot tub is:
V2 = π(2r)^2(1.2h) = 4πr^2(1.2h) = 4.8πr^2h
The difference in volume between the new and current hot tubs is:
V2 - V1 = 4.8πr^2h - πr^2h = 3.8πr^2h
So the volume of the new hot tub is 3.8 times greater than the volume of the current hot tub. Therefore, the volume of the bigger tub is 3.8 times greater than the volume of the smaller tub.

Number of classes the student took is 28.
Given that Mr. Brust school of fine ballet charges $24 per dass and a one time registration fee $150.
A student paid a total of $822 dollars.
How to calculate number of classes?
For finding the number of classes firstly we have to find leaves payment and then we can divide the given charges for each dash.
Now,
Paid $822 - registration fee $150
⇒ $672 leaves
Hence number of classes = \(\frac{672}{24}\) per class
= \(28\) classes
