Answer:
y= -2x + 9
Step-by-step explanation:
I got 2x because you use rise over run. As you can see in the image, the slope goes up two and to the left one ( 2x). It's plus 9 because that where it intersects the 9 on the y-intercept. The slope is negative because the line is going down from left to right ( always read it from left to right).
I hope this helps. I'm not that great at explaining so....:)
Answer:
2x+y-9=0
Step-by-step explanation:
let's take two co ordinates
(X1,y1)=(4,1)
(X2,y2)=(3,3)
Equation using two point :
(y-y1)/(y2-y1)=(x-x1)/(x2-x1)
plug in the values,(y-1)/(3-1)=(x-4)/(3-4)
(y-1)/2=(x-4)/-1
-1*(y-1)=(x-4)*2
-y+1=2x-8
0=2x+y-9
2x+y-9=0
A circle has a diameter of 18 feet. Which following is closest to the l circumference of the circle?
A-28.3ft
B-56.5ft
C-113.1ft
D-245.5ft
circumference =2×pi×r
18/2=9(r)
so...2×pi×9
=54..5
Answer:
56.5 ft
Step-by-step explanation:
We define the number π as the ratio between the circumference and diameter of a circle: π = c/d. Rearranging this equation gives us one for the circumference: c = πd. Using an approximation of π ≈ 3.14 and our value of d = 18 feet, we can find that c = 3.14(18) = 56.52 ft, or 56.5 ft, rounded to the nearest tenth.

Answer:
27 minutes.
Step-by-step explanation:
R = k/t
Substituting given info
600 = k/45
k = 45 * 600 = 27000
So the relation is S = 27000/t
So if R = 1000
1000 = 27000/t
t = 27000/ 1000

The employment status (employed or unemployed) of each individual in the U.S. workforce is a set of data that is of interest to economists, businesspeople, and sociologists. To obtain information about the employment status of the workforce, the U.S. Bureau of the Census conducts what is known as the Current Population Survey. Each month interviewers visit about 59,000 of the 98 million households in the United States and question the occupants over 14 years of age about their employment status. Their responses enable the Bureau of the Census to estimate the percentage of people in the labor force who are unemployed (the unemployment rate).
Question Completion:
(a) Identify the experimental unit.
(b) Define the population of interest to the Census Bureau.
(c) Identify the sample.
(d) What variable is being measured? Is it quantitative or qualitative?
(e) Describe the statistical inference that the economists intend to make.
Answer:
a. The experimental unit is the households visited.
b. The population of interest to the Census Bureau is all US-based individuals aged 14 and above.
c. The sample is 59,000 households.
d. The variable under measure is quantitative (percentage estimate of people in the labor force who are unemployed).
e. The economists want to make a statistical inference of the unemployed population based on the sample data analysis that they conduct.
Step-by-step explanation:
a) Data and Calculation:
Population of interest = 98 million households
Sample from population = 59,000 households
b) The unemployment rate is the percentage of the total workforce of a country that is unemployed and who may be actively seeking employment at a particular period. This implies that the unemployment rate may include persons who are active members of the workforce but may be underemployed.
jesse bought a car for 2,200,000 he sold for a 20% profit from the money raised from the sale he bought another more expensive car which unfortunately he had to sell for a 10% loss that was his overall profit or loss
Answer:1,76,000 Profit
Step-by-step explanation:
Given
Jesse initially bought the car for 2,200,000 and sold it for 20 %
S.P.=C.P.(1+Profit%)
so, the Selling price of the car is S.P.=[tex]2,200,000\times 1.2=2,640,000[/tex]
profit=2,640,000-2,200,000=4,40,000
After this, he bought another car and sells it for a 10 % loss
So, the selling price of the car is [tex]2,640,000\times 0.9=2,376,000[/tex]
loss=2,640,000-2,376,000=2,64,000
Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

Because of the distance from the sun to the earth being 2 meters and 25 inches, we can infer that the 1st president of Canada was Ben Franklin. Ben Franklin is on the 7 dollar bill, which means the Illuminati is real. This means the radius of the earth traveling to the sun from mars to jupiter would be a total of 6.96969696969669 milimeters. So in conclusion, yes she was old enough.

Perry has already taken 8 pages of notes on his own, and he will take 1 page during each
hour of class. After attending 33 hours of class, how many total pages of notes will Perry
have in his notebook?
Answer:
41 pages of notes
Step-by-step explanation:
Since he took 1 page of notes for each hour, and attended 33 hours of class, this will add 33 pages of notes to his notebook.
To find the total, add 8 to this, because he already had 8 pages on his own.
33 + 8
= 41
So, he will have 41 pages of notes in his notebook
Answer:
He will have 41 pages of notes in his notebook.

Devi rides the bus to her grandmother's house every day. She tracked how many minutes the bus rides took for one week: 24 32 25 24 30 30 24 calculate the mean, median, range, and mid range of the bus ride times for a week
Answer:
Mean: 27
Median: 25
Range: 8
Mid Range: 28
Step-by-step explanation:
The value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.
It is given that the time in minutes for which Devi rides the bus in a week is 24, 32, 25, 24, 30, 30, 24.
We have to find out the value of mean, median, range and mid range.
What is mean of numbers ?
The mean of numbers is the ratio of sum of all numbers to the total no. of numbers.
As per the question ;
The time in minutes for which Devi rides the bus in a week is ;
24, 32, 25, 24, 30, 30, 24.
So ;
The mean will be ;
= [tex]\frac{24 + 32 + 25 + 24 + 30 + 30 +24}{7}[/tex]
= [tex]\frac{189}{7}[/tex]
= 27
and
We know that when n is odd number then ; Median is ;
= [tex]\frac{n+1}{2}th[/tex] term
= [tex]\frac{8}{2}th[/tex] term
= 4th term
= 24
and
Range will be ;
= largest number - smallest number
= 32 - 24
= 8
and
Mid range will be ;
= (largest number + smallest number) / 2
= [tex]\frac{32 + 24}{2}[/tex]
= 56 / 2
= 28
Thus , the value of mean, median, range and mid range will be 27 , 24 , 8 and 28 respectively.

The PTA plans a spring carnival on a Saturday in April. If it's a sunny day, they estimate
that they will make $3,000, but if it rains, they will lose $600 because nobody will come.
There's a 30% chance of rain on Saturday. Create a probability model.
Answer:
The probability model is
= P(A or B)
Step-by-step explanation:
a) Data and Calculations:
Estimated revenue if the day is sunny = $3,000
Estimated loss if the day is rainy = $600
The probability of rain = 30%
Therefore, the probability of sunshine = 70% (100 - 30)
The probability model is based on the probability of rain or sunshine
= P(A or B)
= A*70% - B*30%
The outcome from either rain or sunshine
= ($3,000 * 70%) -($600 * 30%)
= $2,100 - $180
= $1,920

Answer:
$27.14
Step-by-step explanation:
Price of 1 DVD: $9.10
Price of 4 DVDs: 4 * $9.10 = $36.40
Discount: 25%
Now we find 25% of $36.40.
25% of $36.40 =
= 0.25 * $36.40
= $9.10
The 25% discount amounts to $9.10. We now subtract $9.10 from $36.40 to find the discounted price.
$36.40 - $9.10 = $27.30
Now we need to apply the 6.75% tax to $27.30.
6.75% of $27.30 =
= 0.0675 * $27.30
= $1.84
The sales tax is $1.84.
Now we add the sales tax amount to the total discounted price.
$27.30 + $1.84 = $29.14
Answer: $27.14

|. Use the quotient rule to differentiate
II. Use the chain rule to differentiate sin(arcsin x) = 2.
III. Use implicit differentiation to differentiate the function y in the relation sin y = x with respect to z.
A) I only
B) Ill only
C) II and III only
D) I, II, and III
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain
d(siny)/dz = dx/dz
(cosy)dy/dz = dx/dz
