Answer: (5, -2)
Step-by-step explanation:
[tex]y= x-7\\2x+y=8[/tex]
Substitute x-7 for y in 2nd equation
[tex]2x+ x-7 =8\\3x-7=8\\3x = 15\\x=5[/tex]
Solve for y

Question:
1. Find the constant of proportionality for Company A and Company B. (to the nearest tenth)
2. Write an equation that represents the relationship between the number of hours h and the total cost for Company A and Company B.
3. Compare the unit rates of Company A and Company B.
Answer:
Proportional relationship formula:
y = kx, where k is the constant of proportionalityUse one of the ordered pairs to calculate the value of k
Company APoint (2, 20)
20 = k*2h = 20/2k = 10The equation: y = 10h
Company BPoint (3, 20)
20 = k*3k = 20/3The equation: y = 20/3hCompany A has greater unit rate as 10 > 20/3

Find the value of y. Be sure to keep the exact value (use square root and don’t round your answer).
Answer:
y = 8·√3
Step-by-step explanation:
From the drawing of the right triangle, we have;
The length of the opposite leg to the given 60° (reference) angle = 12
The length of the adjacent leg to given 60° (reference) angle = x
The length of the hypotenuse side = y
By trigonometric ratios, we have;
[tex]sin(Reference \, Angle) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
Therefore, we have;
[tex]sin(60^\circ) = \dfrac{12}{y}[/tex]
From the value of sin(60°), we have;
[tex]sin(60^\circ) = \dfrac{\sqrt{3} }{2}[/tex]
[tex]\therefore y= \dfrac{12}{sin(60^\circ) } = \dfrac{12}{\dfrac{\sqrt{3} }{2} } = \dfrac{2 \times 12 \times \sqrt{3} }{{{3} } } = \dfrac{24 \times \sqrt{3} }{{{3} } } = 8 \cdot \sqrt{3}[/tex]
y = 8·√3
[tex]\left(x= \dfrac{12}{tan(60^\circ) } = \dfrac{12}{{\sqrt{3} } } = 4\cdot \sqrt{3} \right)[/tex]

The governor of Florida would like to estimate the mean age of all Florida residents. To do so, he randomly selects 500 Florida residents and determines their mean age to be 58.2 years. However, according the most recent census data, the mean age of all Florida residents is 55.6 years. Which of the following properly describes the number 58.2?
sample
statistic
population
parameter
Answer:
Sample
Step-by-step explanation:
Just took on Edge.
Sample describes the number 58.2 in the given problem.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A sample is a subset of individuals or items selected from a population, and statistics are values calculated from a sample.
As given, the governor of Florida randomly selected 500 Florida residents and determined their mean age to be 58.2 years.
This value is a sample statistic because it is calculated from a sample of individuals and is used to estimate a population parameter.
The number 58.2 represents a sample statistic.
Hence, sample describes the number 58.2 in the given problem.

Find the slope. (4, 10) and (-2,-5)
Answer:
Slope in fraction form = 5/2
Slope in decimal form = 2.5
========================================================
Work Shown:
m = (y2-y1)/(x2-x1)
m = (-5-10)/(-2-4)
m = (-15)/(-6)
m = (-3*5)/(-3*2)
m = 5/2 slope in fraction form
m = 2.5 slope in decimal form
-----------------
Explanation:
The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.
I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)
The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".
Or you can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x

a point is chosen at random on AK. what is the probability that the point will be on CD. don't forget to reduce
Answer:
your answer is 1/10. hope this helps!
The probability that the point will be on CD will be 1/10 or 0.10.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A point is chosen at random on AK.
The distance between A and K will be 20.
Then the probability that the point will be on CD will be
The distance between C and D will be 2.
Then the total event will be
Total event = 20
The favorable event will be
Favorable event = 2
Then the probability is defined as the ratio of favorable event and total event.
P = Favorable event / Total event
P = 2 / 20
P = 1 / 10
P = 0.10
Then the probability that the point will be on CD will be 1/10 or 0.10.

THE NUMBER 1-10 ARE IN A BAG, YOU TAKE 2 OUT WITHOUT REPLACEMENT. WHAT IS THE PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER.
Answer:
1 / 18
Step-by-step explanation:
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = Number of favorable outcome / Total number of outcomes
Favorable outcome = 1
Total number of outcome (1,2,3,4,5,6,7,8,9,10) = 10
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = 1 / 10
PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = Number of favorable outcome / Total number of outcomes
Favorable outcome (2,4,6,8,10) = 5
Total number of outcomes (1,2,3,4,5,6,8,9,10) = 9
PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = 5/9
PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER = 1 / 10 * 5 / 9 = 1 / 18

The width of a rectangle measures (3v-3w) centimeters, and its length measures (5v-9w) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer: The Perimeter of the rectangle, P= 16v −24w
Step-by-step explanation:
Perimeter of a rectangle = 2( L +W) = 2L + 2W
The width of a rectangle is given as (3v-3w) centimeters,
its length is given as (5v-9w) centimetres
The Perimeter,P will now be = 2L + 2W
P=2( 3v-3w) + 2( 5v-9w)
P=6v −6w + 10v - 18 w
adding like terms
P=6v + 10v −6w −18 w
P= 16v −24w

It is a GP because the ratio between two consecutive terms are same..
Here,
First term: [tex]a = 2[/tex]
Common ratio: [tex]r=\dfrac{a_2}{a_}[/tex]
[tex]r=\dfrac{4}{2}[/tex]
[tex]r=2[/tex]
The explicit formula of GP is:
[tex]a_n=ar^{n-1}[/tex]
Putting [tex]a=2,r=2[/tex], we get
[tex]a_n=2(2)^{n-1}[/tex]
Put n=11 to find the 11th term of the given sequence.
[tex]a_{11}=2(2)^{11-1}[/tex]
[tex]a_{11}=2(2)^{10}[/tex]
[tex]a_{11}=2(1024)[/tex]
