Pharmex is a chain of drugstores that operate around the country. To see how effective its advertising and other promotional activities are, the company has collected data from 50 randomly selected metropolitan regions. In each region, it has compared its own promotional expenditures and sales to those of the leading competitor in the region over the past year. There are two variables: "Promote" reflects Pharmex’s promotional expenditures as a percentage of those of the leading competitor, and "Sales" reflects Pharmex’s sales as a percentage of those of the leading competitor. A portion of the data appears below. Show all work.

A.) From the resulting plot, tbe slope of the graph is positive, hence, we can conclude that there exist a positive relationship between the variables 'promote' and 'sale'.
The linear trend line gives the best fit for the data with a correlation Coefficient, R value of 0.5935
The R² value is 0.3522. R² is the Coefficient of determination which gives the percentage of explained variation. For this data, about 35% of variation in sales is given by the best fit line.

Answer:
53.13⁰
Step-by-step explanation:
Use sine:
sinθ=opposite/hypotenuse
sin∠A=4/5
∠A=sin⁻¹(0.8)=53.13010235415≈53.13⁰
The measure of angle A is 53.13 degrees in right triangle ABC.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
The given triangle ABC is a right angled triangle
AB=3cm, BC=4cm and AC is 5cm
We have to find the ∠A
By using sine rule we find this
sin∠A = opposite side/hypotenuse
=4/5
sin∠A =0.8
Take sin⁻¹ on both sides
∠A =sin⁻¹(0.8)
= 53.13 degrees.
Hence, the measure of angle A is 53.13 degrees.

Answer:
b, d, c, a, e
Step-by-step explanation:
A formula should always come with a definition of the variables it uses. Here, you're supposed to somehow magically figure out what the variables are.
A = P(1 +r/n)^(nt)
A is the amount of the investment of principal P after t years, compounding annual rate r n times per year.
__
Then your blanks get filled like this:
1. A -- b the value
2. P -- d the principal
3. r -- c the annual interest rate
4. n -- a number of times compounded per year
5. t -- e number of years
Which system models the height of the tennis ball and the height of the dog's mouth over time? h = 4.5t + 18 and h = -16t2 + 1.5t + 21 h = 18t + 4.5 and h =-16t2 + 21t + 1.5 h = -16t2 + 4.5t + 18 and h = -16t2 + 1.5t + 14 h = -16t2 + 18t + 4.5 and h = -16t2 + 21t + 1.5
Answer:
the first answer is d and the second one is c
Step-by-step explanation:
edge
The height of the tennis ball and the height of the dog's mouth over time are h = 4.5t + 18 and h = -16t2 + 1.5t + 21 respectively. Therefore, the correct option is option A.
What is height?Height is a measurement of vertical distance, or how high or something someone is (how tall they are). For instance, "The altitude of that structure is 50 m" and "The height of such an aircraft in-flight is roughly 10,000 m". Christopher Columbus, for instance, has a height of 5 feet 2 inches.
Height is more frequently referred to as altitude when describing the vertical position from sea level. Additionally, elevation (height over sea level) is known as altitude if the point is connected to the Earth. The height of the tennis ball and the height of the dog's mouth over time are h = 4.5t + 18 and h = -16t2 + 1.5t + 21 respectively.
Therefore, the correct option is option A.
