The required coordinates of the preimage are (-7, 11) when the point is rotated 270° about the origin.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
We have been given that a point is rotated 270° about the origin. The image of the point is (-11,7).
The coordinates of the preimage would be :
x = x cos θ + y sin θ
y = x sin θ + y cos θ
Here x = -11 ,y = 7 and θ = 270°
Substitute the values in the above equations,
x = (-11) cos 270° + 7 sin 270° = -7
y = (-11) sin 270° + 7 cos 270° = 11
Therefore, the required coordinates of the preimage are (-7, 11).

Five different awards are to be given to three students. Each student will receive at least one award. In how many different ways can the awards be distributed?
Answer:
Two ways
Step-by-step explanation:
Blue is students and Yellow is the trophies.
Total number of different ways that the awards can be distributed is; 150 ways.
It is clear from the question that the awards and the students are different. Now, each student will receive at least one award.This means that the five different awards could be separated into;
3 + 1 + 1 awards or 2 + 2 + 1 awards.
Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;⁵C₃ × 3! = 60 ways
Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;((⁵C₂ × ³C₂)/2) × 3! = 90 ways
Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.Read more at; https://brainly.com/question/20373683

What are the negative and positive coterminal angles of 240 degrees?
The negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.
What are coterminal angles?Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.
We have to find the coterminal angles of 240 degrees
Coterminal angles are those whose initial and terminal sides coincide. Depending on whether the given angle is in degrees or radians, adding or subtracting 360° or 2 from each angle yields the coterminal angles. There are countless coterminal angles that can be discovered.
Thus, the negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

A population of values has a normal distribution with μ = 245.3 and σ = 96 . You intend to draw a random sample of size n = 50 . Find the probability that a single randomly selected value is greater than 246.7. P(X > 246.7) = 0.0146 Incorrect Find the probability that a sample of size n = 50 is randomly selected with a mean greater than 246.7. P(M > 246.7) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
Answer:
0.4589
Step-by-step explanation:
We solve using z score formula
The z score formula for a random number of samples is:
z = (x-μ)/σ/√n, where x is the raw score, μ is the population mean, and σ is the population standard deviation
Hence:
z = 246.7 - 245.3/96/√50
z = 0.10312
Probability value from Z-Table:
P(x<246.7) = 0.54107
P(x>246.7) = 1 - P(x<246.7) = 0.45893
Approximately to 4 decimal places = 0.4589
The probability that a single randomly selected value is greater than 246.7 is 0.4589

A local specialty store sells two brands of yogurt. Brand A is a fruit yogurt that comes in a 12-ounce container for $2.88. Brand B is a fruit yogurt that comes in a 16-ounce container for $4.48. Which one is a better buy: Brand A or Brand B?
Answer:
0.04
Step-by-step explanation:
Brand A:
so x is equal to 0.24
Brand B:
so x is equal to 0.28
Now the difference of cost would be Brand B - Brand A which would give you 0.04.
Create a 5th degree trinomial that has a constant term of 3.
Answer:
[tex]2x^5+3x^2+3[/tex] is a trinomial having with:
three terms degree 5 and The constant term '3'Step-by-step explanation:
Considering the trinomial
[tex]2x^5+3x^2+3[/tex]
Any polynomial with 3 terms is a trinomial, so it is a trinomial.It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.
'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.
Therefore, [tex]2x^5+3x^2+3[/tex] is a trinomial having with:
three terms degree 5 and The constant term '3'Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How many smaller bottles did Deion fill?
Answer:
4 bottles
Step-by-step explanation:
Given
[tex]Fertilizer = \frac{1}{2}L[/tex]
[tex]Bottles = \frac{1}{8}L[/tex]
Required
Determine the number of bottles
Represent the number of bottles with N
This implies that N bottles of [tex]\frac{1}{8}L[/tex] fit into [tex]\frac{1}{2}L[/tex] of fertilizer. The relationship between them is:
[tex]Fertilizer = Bottles * N[/tex]
[tex]\frac{1}{2}L = \frac{1}{8}L* N[/tex]
[tex]\frac{1}{2} = \frac{1}{8}* N[/tex]
Multiply through by 8
[tex]8 * \frac{1}{2} = 8 * \frac{1}{8}* N[/tex]
[tex]4 = 1* N[/tex]
[tex]4 = N[/tex]
[tex]N = 4[/tex]
Hence, there are N = 4
A car can travel 480 miles on a full tank of petrol. The tank holds 60 litres. The fuel gauge shows there and 15 litres left in the tank. How many more miles can the car travel before it runs out of petrol?
Answer:
Miles= 120
Step-by-step explanation:
Giving the following information:
A car can travel 480 miles on a full tank of petrol. The tank holds 60 liters.
First, we need to calculate the miles per liter:
Miles per litre= 480 / 60
Miles per litre= 8 miles
Now, the miles that can be driven with 15 liters:
Miles= 15*8
Miles= 120

Answer:
64r -48r -144
Step-by-step explanation:
The January cost expression is ...
62p -48p -144 -432 = profit
The cost is identified as having 3 components, so the profit will have 4 components:
(selling price)×p - ((cost per unit)×p +(fixed monthly cost)) -(first month startup cost) = profit
Comparing this to the given equation, we identify the components as ...
selling price = 62
cost per unit = 48
fixed monthly cost = 144
first month startup cost = 432
We note that 432 = 3×144, so is consistent with the description of startup costs.
Increasing the selling price by $2 will raise it from 62 to 64. In February, the initial month startup cost disappears, so the profit equation becomes ...
(selling price)×r - ((cost per unit)×r +(fixed monthly cost)) = profit
64r -48r -144 = profit
When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120. Find the hourly rate of pay for Ben and Judy.
Answer:
They each earn 15 an hour
Step-by-step explanation:
Answer:
They both make $15
Step-by-step explanation:
In the first scenario Judy worked for 4 hours, (4)*(15)=60 plus Ben, (1)*(15)=15 which equals 75. In the second scenario, Judy works 2 hours so (2)*(15)=30 and Ben works 6, (6)*(15)= 90 which is 120.
