counterclockwise about the origin
( [ ? ] , [ ? ] )
Answers
Answer:(1,2)
Step-by-step explanation:
The image of point P = (2, -1) is (1, 2)
What is rotation?"It is a transformation in which the object is rotated about a fixed point.""An object can be turned clockwise or counterclockwise on the coordinate plane"For given question,
We have been given a point P = (2, -1)
We know that if point (x, y) is rotated 90 degrees counterclockwise about the origin then the coordinates of image is (-y, x)
So, when point P is rotated 90 degrees counterclockwise about the origin then the coordinates of the image would be (-(-1), 2) = (1, 2)
Therefore, the image of point P is (1, 2)

Students from the local high school are selling tickets to the town's annual carnival. Adult
admission is $5.00 and child admission is $2.50. Two hours after the carnival opened its first
day, 440 tickets had been sold totaling $1900. How many adults and how many children
entered the carnival during the first two hours it was open?
Answers
Answer:
320 adults and 120 children
Step-by-step explanation:
First set up two sets of equations. One will equal the total amount of money sold and the other will equal the total amount of tickets sold.
5a + 2.5c = 1900 where a is the # of adult tickets sold and c is the # of children tickets sold
a + c = 440
Now solve for either a or c in the second equation. I chose to solve for a. a=440-c
Use that to substitue into the other equation.
5 (440-c) +2.5c = 1900
2200-5c +2.5c = 1900
-5c+2.5c = -300
-2.5c=-300
c=120
Now plug 120 into the equation a+c=440 and solve for a

The value of the subtraction will be equal to -3u-4v.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two expressions are (5u + 6v) and (8u + 10v). The subtraction will be calculated as,
5u+6v-(8u+10v)
S =5u+6v+-1(8u+10v)
S =5u+6v+-1(8u)+-1(10v)
S =5u+6v+-8u+-10v
(combine like terms)
S =5u+6v+-8u+-10v
S =(5u+-8u)+(6v+-10v)
S =-3u-4v
Therefore, the value of the subtraction will be equal to -3u-4v.

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval
Answers
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.

What conclusion can you draw about angles of elevation for parasailing boats traveling at the same speed?
Answers
Question:
A boat is travelling at 30 mph has a 400 ft. tow line results in the height of the rider in the parasail above the water level of 300 ft.
a) Draw a labelled diagram of the situation
b) Determine the angle of elevation of the parasail rider
c) Parasailing boats traveling at the same speed will have the same angle of elevation
Answer:
a) Please find the attached drawing of the parasail boat created with MS Visio
b) The angle of elevation of the parasail rider from the boat is approximately 48.6°
Step-by-step explanation:
a) Please find the labelled diagram of the parasailing boat created with MS Visio
b) sing trigonometric ratios, we have;
[tex]sin(\theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
The opposite leg = The height of the parasail rider above water = 300 ft.
The hypotenuse = the length of the tow line = 400 ft.
θ = The angle of elevation of the parasail rider
[tex]\therefore sin(\theta) = \dfrac{300 \, ft.}{400 \, ft.} = 0.75[/tex]
θ = Arctan(0.75) ≈ 48.6°
The angle of elevation above the horizontal of the parasail rider from the boat, θ ≈ 48.6°
c) From the construction of the drawing and the derivation of the angle of elevation given only the length of the tow line and the height given to the parasail rider by the speed of the both,
Parasailing boats traveling at the same speed, having the same length of tow line, will have the same angle of elevation, provided other factors that have an effect on the angle of elevation are the same
A drawer contains a blue shirt, a black shirt, and a white shirt. Another drawer contains a blue pair of pants and a black pair of pants. One shirt and one pair of pants are chosen at random.
How many different possible outcomes are there?
I will mark brainiest on whoever gets it right.
Answers
Answer: 6 possible outcomes
Step-by-step explanation:
blue shirt - blue pants
blue shirt - black pants
black shirt - blue pants
black shirt - black pants
white shirt - blue pants
white shirt - black pants
6 outcomes
The total number of outcomes is given by the equation A = 6 outcomes
What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the number of outcomes be represented as set A
Now , the shirts be represented as set 1
The value of set 1 = { blue shirt , black shirt , white shirt }
The number of elements in set 1 = 3
The pair of pants be represented as set 2
The value of set 2 = { blue pair , black pair }
The number of elements in set 2 = 2
Now , the total number of possible outcomes A = number of elements in set 1 x number of elements in set 2
Substituting the values in the equation , we get
The total number of possible outcomes A = 3 x 2
The total number of possible outcomes A = 6 outcomes
Therefore , the value of A is 6 outcomes
Hence , the number of outcomes is 6
