Answer:
0.0000024
Step-by-step explanation:
Given :
2.4 x 10-6
10^-6 = 0.000001
2.4 * 10^-6 = 2.4 * 0.000001
2.4 * 10^-6 = 0.0000024
Hence, in standard form : 0.0000024
A marketing research manager analyzes the data collected through loyalty cards at a popular local coffee shop. She investigates the relationship between repeated visits and the age of the customer. Interpret the analysis results, if her findings show that the correlation coefficient between these two variables is 0.64. What does it mean from a marketing perspective
Answer: See explanation
Step-by-step explanation:
Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.
In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .
find the perimeter of each polygon. Assume that lines which appeared to be tangent are tangent.
9514 1404 393
Answer:
A) 54.4
Step-by-step explanation:
The perimeter of a circumscribing quadrilateral is twice the sum of the lengths of opposite sides.
P = 2(17.6 +(2.9 +6.7)) = 2(27.2)
P = 54.4
Answer:
perimeter of each polygon
A property that offers a 7.5 percent return on the listing price has a monthly net of $810.
The property is listed at
Answer:
$129,600
Step-by-step explanation:
Given that
The return percentage is 7.5%
And, the monthly net is $810
We need to find the property listed price
Since we assume that the return percentage is on annual basis
So, for monthly, it is
= 7.5% ÷ 12
= 0.625%
Now the property listed price is
= $810 ÷ 0.625%
= $129,600

The half-life of caffeine in a person's bloodstream is about 6 hours. If a person's bloodstream contains 70 milligrams of caffeine,how much of that caffeine will remain after 15 hours ?
Answer:
12.4 mg
Step-by-step explanation:
a = p(1/2)^(t/h)
p is the initial quantity = 70
t is the time = 15
h is the half life = 6
plug in the givens
a = 70(1/2)^(15/6)
a = 12.3743686708
12.4 mg
Two lines intersect, and you know the measure of one angle. How can you determine the measures of the other three angles
Answer:
Opposite angles are the same measure.
Angles around a point = 360°
When you add all the angles, you get 360.
Angle a and b would measure the same and so would angle d and c. So you double the measure for one of those angles and subtract it from 360.
Then, you half that value( divide by 2) and this is to find the measure of the other angle

Mr. Litterski creates a ball from rubber bands.
The circumference of the ball is 9.4 inches. What is the approximate surface area and volume of the ball? Round your answers to the nearest unit. HELP PLEASE!!
Answer:
The surface area of the ball is of 29 square inches.
The volume of the ball is of 15 cubic inches.
Step-by-step explanation:
The ball has an spherical format:
Circumference of a sphere:
The circumference of a sphere is 6.2832 times the radius.
Surface area
[tex]A = 4\pi r[/tex]
In which r is the radius.
Volume:
[tex]V = \frac{4\pi r^3}{3}[/tex]
The circumference of the ball is 9.4 inches.
So the radius is:
[tex]6.2832r = 9.4[/tex]
[tex]r = \frac{9.4}{6.2832} = 1.53[/tex]
Surface area
[tex]A = 4\pi(1.53)^2 = 29.3[/tex]
Rounding to the nearest unit, the surface area of the ball is of 29 square inches.
Volume:
[tex]V = \frac{4\pi (1.53)^3}{3} = 14.9[/tex]
Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

Answer:
8.66 cm
Step-by-step explanation:
From the diagram :
The vase of the triangle = 9.9cm - 4.9 cm = 5cm
Hence, using Pythagoras rule :
Opposite = √hypotenus² - Adjacent²
Opposite = √10²-5²
Opposite = √100 -25
Opposite= √75
= 8.66 cm

During the month of june, jessica volunteers at a library every 6 days and at a veterinarians office every 10 days. jessica’s first visit to the library was on June 6 and her first visit to the veterinarian office was on June 1th.
What day in June will jessica volunteer at both locations?
Anwser Options
june 6
june 10
june 18
june 20
june 24
june 30
The day in June, Jessica volunteered at both locations if she volunteers at the library every 6 days and at a veterinarian's office every 10 days is June 30, so option F is correct.
What is LCM?The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.
For instance: The LCM of 2 and 3 is 6.
Given:
Jessica volunteers library every 6 days,
Jessica's veterinarian's office, every 10 days,
So for her visit to both, the place takes the LCM of 6 and 10,
LCM of 6 and 10 = 30,
Hence, on the 30th day, she visits both places so if she starts volunteering from the 1st of June then she will visit both places on the 30th of June.
Therefore, The day in June, Jessica volunteered at both the location if she volunteers at a library every 6 days and at a veterinarian's office every 10 days. Jessica’s first visit to the library was on June 6 and her first visit to the veterinarian's office was on June, 1st is June 30.
