Answer:
Bloomberg Business week NorthAmerica Subscribers
; Quantitative ; Qualitative ; No ; Yes ; No
Step-by-step explanation:
Sample size = 2861
Percentage respondent with annual income ≥ 75000 = 59%
Percentage having an American Express credit card
1.What is the population of interest in this study?
Bloomberg business week NorthAmerica Subscribers
2. Quantitative
Annual income is quantitative because it is numeric, that is repress red by numbers which can be used to perform sensible numerical computation such as additions, mean, multiplication and so on.
3.Qualitative
No ; ownership of an American express card is a Qualitative variable as it will take responses as (yes or no), even when represented or coded as numbers, it will make no numerical sense to peform mathematical calculations with it.
4.
No ; time series data has to do with data collected with respect to a particular month, year or seasonal data.
5. Determine whether the following two statistical inferences may be made based on the sample data collected.
An estimated 59% of the population of subscribers has an annual income of $75,000 or more.
Yes ;
An estimated 60% of the population of subscribers has an American Express credit card.
No ; the research says 50% and not 60%

The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below: A graph titled Motion of a Car is shown with Time in hours labeled on x-axis and Distance from Starting Point in miles labeled on y-axis. The scale on the x-axis shows the numbers 1, 2, 3, 4, 5, 6, and the scale on the y-axis shows the numbers 0, 13, 26, 39, 52, 65, 78. There are three straight lines in the graph. The first line joins ordered pair 0, 0 with 2, 26. The second straight line joins 2, 26 and 3,26 and the third straight line joins ordered pair 3,26 with the ordered pair 5,52. Which of the following best describes the motion of the car shown? (1 point) It travels for 2 hours, then stops for 3 hours, and finally travels again for 2 hours. It travels for 2 hours, then stops for 3 hours, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Answer:
The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Step-by-step explanation:
In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.
In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.
In the last segment, it moved up again for 2 hours.
It travels for 2 hours, then stops for 1 hour, and finally travels again for 5 hours. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
What is a simple definition of distance?Distance is the total movement of an object without any regard for direction. We can define distance as how much ground an object has covered despite its starting or ending point.
What is the scientific term for distance?Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Which of the following proves ABC=ADEF?
Answer:
C) ASA
Step-by-step explanation:
Use what's given to limit your options:
We have two pairs of congruent angles, <B and <E, <C and <F, which means we can eliminate choices B and D because both don't account for both angle pairs.
Since we read proofs from left to right, only C works because the side is in between.
Amarosa Logistics purchased a new pick-up for the office employees to use for $28,000.00. The vehicle is expected to last for
10 years with a residual value of 56,250,00. For tax purposes, it is assumed that the depreciation is linear and the pickup's
value can be determined by the equation
p(t) = -21755 + 28,000,
where x is the number of years since the pick-up was purchased. What is the depreciated value of the pick-up after 3 years?
A $25,825.00
B. $21,475,00
C. $15,225.00
D 519,300.00
Answer:
I think B but I am not sure.
The depreciated value of the pick-up after 3 years is $15,225
Given that Amarosa Logistics purchased a new pick-up for the office employees to use for $28,000.00.
The vehicle is expected to last for 10 years with a residual value of 56,250,00.
The depreciation is linear and the pickup's value can be determined by the equation
p(t) = -21755t + 28,000
To find the depreciated value of the pick-up after 3 years
Plug in t as 3
p(t) = -21755(3)+ 28,000
=$15,225
Hence, $15,225 is the depreciated value of the pick-up after 3 years

a. ∫ 3xdx
b. ∫ √15-y^2dy
c. ∫ √81- x^2 dx
d. ∫ (5- y/7)dy
Answer:
a. [tex]\frac{3}{2}[/tex]
b. [tex]\frac{15\pi }{4}[/tex]
c. [tex]\frac{81\pi }{2}[/tex]
d. [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
P.S - The exact question is -
a. [tex]\int\limits^1_0 {3x} \, dx[/tex]
y = 3x
Shape of the given integral = A Triangle
Area of Triangle = [tex]\int\limits^1_0 {3x} \, dx[/tex] = [tex]\frac{1}{2}[/tex]×1×3 = [tex]\frac{3}{2}[/tex]
The graph of integral is as follows :
b.[tex]\int\limits^\15 _0 {\sqrt{15 - y^{2} } } \, dy[/tex]
x = [tex]\sqrt{15 - y^{2} }[/tex]
⇒x² = 15 - y²
⇒x² + y² = 15
⇒x² + y² = (√15)²
Shape of the integral = Quarter circle of radius √15
Area of Quarter circle = [tex]\int\limits^\15 _0 {\sqrt{15 - y^{2} } } \, dy[/tex] = [tex]\frac{1}{4}[/tex]×[tex]\pi[/tex]×r² = [tex]\frac{1}{4}[/tex]×[tex]\pi[/tex]×(√15)² = [tex]\frac{15\pi }{4}[/tex]
The graph of the following integral is as follows :
c.[tex]\int\limits^9_-9 {\sqrt{81 - x^{2} } } \, dx[/tex]
y = [tex]\sqrt{81 - x^{2} }[/tex]
⇒y² = 81 - x²
⇒y² + x² = 81
⇒y² + x² = 9²
Shape of the integral = Semi circle of radius 9
Area of semi circle = [tex]\int\limits^9_-9 {\sqrt{81 - x^{2} } } \, dx[/tex] = [tex]\frac{1}{2}[/tex]×[tex]\pi[/tex]×r² = [tex]\frac{1}{2}[/tex]×[tex]\pi[/tex]×9² = [tex]\frac{81\pi }{2}[/tex]
The graph of the following integral is as follows :
d. [tex]\int\limits^7_0 {5 - \frac{y}{7} } \, dy[/tex]
x = 5 - [tex]\frac{y}{7}[/tex]
⇒[tex]\frac{y}{7}[/tex] = 5 - x
⇒y = 35 - 7x
At y = 0 , x = 5
At y = 7 , x = 4
Shape of the integral = A triangle
Area of Triangle = [tex]\frac{1}{2}[/tex]×(5-4)×7 = [tex]\frac{1}{2}[/tex]×(1)×7 = [tex]\frac{7}{2}[/tex]

Convert from vertex form to standard form. (3 pts). f(x) =(x-3)squared + 6
Answer:
Standard form of [tex]f(x) =(x-3)^2 + 6[/tex] is [tex]\mathbf{x^2-6x+15}[/tex]
Step-by-step explanation:
Convert from vertex form to standard form [tex]f(x) =(x-3)^2 + 6[/tex]
If the vertex form is: [tex]a(x-h)^2+k[/tex]
The Standard form is: [tex]ax^2+bx+c[/tex]
Now, converting [tex]f(x) =(x-3)^2 + 6[/tex] into standard form
We know that: [tex](a-b)^2=a^2-2ab+b^2[/tex]
Using the formula:
[tex]f(x) =(x-3)^2 + 6\\f(x)=x^2-2(x)(3)+9+6\\f(x)=x^2-6x+15[/tex]
So, Standard form of [tex]f(x) =(x-3)^2 + 6[/tex] is [tex]\mathbf{x^2-6x+15}[/tex]

I work five days a week for eight hours a day last month I work 20 days my truck it’s 21 miles per gallon I drive an average speed of 45 mph I drive about 350 miles per day gas cost $3.499 per gallon how much money did I spend on gas last month
Answer:
$1166.32
Step-by-step explanation:
We are given that
Total number of working days=20
Average speed of truck=45mph
Distance drive per day=350 miles
Distance traveled in 1 gallon=21 miles
Cost per gallon=$3.499
We have to find the money spend on gas
Total distance traveled in 20 days=[tex]350(20)=7000miles[/tex]
Total gas used in 20 days=[tex]\frac{7000}{21}[/tex]
Total gas used in 20 days=333.33 gallon
Cost of 333.33 gallon=[tex]3.499\times 333.33[/tex]
Cost of 333.33 gallon=$1166.32
Hence, money spend on gas last month=$1166.32

What are the basic principles of probability?
The probability of an event can only be between 0 and 1 and can also be written as a percentage.The probability of the event is often written as If, the then event has a higher chance of occurring than an event.If, then events are equally likely to occur.Let's suppose the number of heads is r which represents the head times and in this case r = 4
Assuming that the coin is unbiased, you have the probability of success ‘p’(where p is considered as success) [tex]\frac{1}{2}[/tex] and the probability of failure ‘q’ (where q is considered as failure).
The number of trials is represented by the ’n’ and here n = 12.
Now use the function for a binomial distribution:
P(R = r) = nCrprqn-r
P(R = 4) = (12C4)(1/2)4(1/2)12-4
= 495/4096
= [tex]\frac{495}{4096\\}[/tex]
= 12.0849609%

Step-by-step explanation:
Carmen's water bottle = 1.8 litres ≈ 2 litres
Jorge's water bottle = 2[tex]\frac{2}{5}[/tex] = 2.4 litres ≈ 2 litres
Therefore, from estimate, Jorge's water bottle does not hold half litre more of water than Carmen's.
