The price of Stock A at 9 A.M. was $12.41. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $13.16. It begins to decrease at the rate of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
1.50 Hours
Step-by-step explanation:
Given:
→ The price of Stock A at 9 A.M. was $12.41. → Since then, the price has been increasing at the rate of $0.12 each hour. → At noon the price of Stock B was $13.16. → It begins to decrease at the rate of $0.14 each hour.To Find:
If the two rates continue, in how many hours will the prices of the two stocks be the same?
Solve:
Price of stock A at 9 a.m.= $12.41
The price has been increasing at the rate of $0.12 each hour.
Increase in price after 3 hours = 0.12 × 3 = 0.36
Price of Stock A at noon= 12.41+0.36 =12.77
Let n be the no. of hours after which the prices of both the stocks will be same .
So, Increase in price after n hours = 0.12 n
Price of Stock A after n hours = 12.77+0.12 n
Price of stock B = 13.16
The price has been decreasing at the rate of $0.14 each hour.
Let n be the no. of hours
So, Increase in price after n hours = 0.14 n
Price of Stock B after n hours =13.16-0.14 n
ATQ
12.77 + 0.12n = 13.16 - 0.14n
-12.77 + 13.16 = 0.12n + 0.14n
0.39 = 0.26n
0.39/0.26 = n
n = 1.50
Hence the prices of the two stocks be the same after 1.50 hours after 12 pm .

In this activity, you will analyze a statistical study for a given situation and apply randomization to collect data from which valid conclusions may be drawn.
To meet the company’s sales goals, the sales director for the pet food company decided to provide training for some of the sales representatives in the Midwest and Northeast regions. After conducting a one-month training program, the sales director analyzed the effectiveness of the program by conducting a statistical study.
Question 1
The purpose of the sales director’s study is to determine whether attending the training program caused an increase in sales for representatives from the two regions. So the sales director collected sales data from both groups (those receiving training and those receiving no training) for three months after the one-month program and compared the number of orders secured by those who attended the training program with the number of orders secured by those who didn’t attend.
Part A
Question
Select the correct answer from each drop-down menu.
The sales director conducted because a treatment applied to the sales representatives.
This is the best statistical study for this situation because the sales director is trying to establish .
Part B
Suppose there are 1,000 total sales representatives in the Midwest and Northeast regions, with 500 sales reps in each region. Describe the best way for the sales director to include 200 sales representatives, with an equal number from each region and an equal number in each group, while yielding valid conclusions in the study.
Type your response in the box.

Question 2
For three months after the training program, the sales director collected the sales data for the 200 sales representatives from the Midwest and Northeast regions. The director then broke down the number of sales orders for the representatives according to whether they received training or not. This data is shown in the table.
Three Months’ Sales Orders
Training No Training
Midwest 234 196
Northeast 252 178
Question
Use the data shown in the table to complete each statement.
Select the correct answer from each drop-down menu.
For the Midwest region, the average number of sales orders per representative for the group that had training is more than the average number of sales per representative for the group that had no training.
For the Northeast region, the average number of sales orders per representative for the group that had training is more than the average number of sales per representative for the group that had no training.
The data from the sales director’s study indicates that the one-month training program sales.
Question 1 - The sales director was inclined to conduct an experiment because a treatment was applied to the sales representative.
A causality statistical study would be best.
Question 2 - In the Midwest region, the difference between those with training and without led to a 0.38 difference.
In the Northeast, the difference between those with training and without led to a 0.74 difference.
This means that a one-month training program increases sales.
What does the data show?The data shows that because a treatment was applied to sales representatives in that some of them were trained, the best way to find out the effect of this treatment would be an experiment.
This experiment would show if there is a causality relationship between training and sales numbers.
What is the difference in amount sold?Midwest:
= (234 - 196) / 100
= 0.38
Northeast:
= (252 - 178) / 100
= 0.74
Those with training in the Midwest sold 0.38 more than those without training. And those with training in the Northeast sold 0.74 more.
This means that the training does indeed increase sales.

The slope of a line is given by the formula:
horizontal change
m
vertical change
True
False
Answer:
False
Step-by-step explanation:
The defining characteristic of a line is that is has a constant average rate of change.
That is, for a given line, for whatever two points are selected, the average rate of change between then will be the same. This constant average rate of change is called the slope of the line.[tex]slope=\frac{rise}{run}=\frac{verticalchange}{horizontal change} =\frac{y}{x} =\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
The first two versions are more geometric in nature (applied problems)The second two version are more algebraic (points on the x-y plane) Slope is Positive when the line rises from left to right.Negative when the line falls from left to rightZero when the line is horizontal ( no change in y)Undefined when the line is vertical (no change in x)Henry's mom bought a candle with a circumference of approximately 45.1846 cm.

Here, we will use the concept of integration and algebric identities
Integration is the process of finding function that is a derivate of given function Three important trigonometric identities :-[tex]\sf{ sin^{2}{\theta}+ cos^{2}{\theta} = 1 }[/tex][tex]\sf{ 1 + tan^{2}{\theta} = sec^{2}{\theta} }[/tex][tex]\sf{ 1 + cot^{2}{\theta} = cosec^{2}{\theta} }[/tex]Let's Begin :-We have,
[tex]\bold{\displaystyle\int}{\bold{\dfrac{ cos^{2}x}{1 + sinx}}}{\bold{dx}}[/tex]
By using trigonometric identity,
[tex]\sf{ sin^{2}{\theta}+ cos^{2}{\theta} = 1 }[/tex][tex]\sf{\displaystyle\int}{\sf{\dfrac{ 1 -sin^{2}x }{1 + sinx}}}{\sf{dx}}[/tex]
By using algebraic identity :-
[tex]\sf{ a^{2} - b^{2} = ( a + b) (a - b) }[/tex][tex]\sf{\displaystyle\int}{\sf{\dfrac{ (1 + sinx) (1 - sinx) }{1 + sinx}}}{\sf{dx}}[/tex]
[tex]\sf{\displaystyle\int}{\sf{( 1 - Sinx)dx}}[/tex]
[tex]\sf{ {\displaystyle\int} dx - {\displaystyle\int}sinxdx}[/tex]
We know that,
[tex]\sf{{\int\displaystyle}sin{\theta} d{\theta} = - cos {\theta} + C }[/tex][tex]\sf{ x - (-cosx) + c}[/tex]
[tex]\bold{ x + cosx + c}[/tex]
Hence, The answer is x + Cosx + c.
We are given with an integral and need to solve the integral , so let's start ;
[tex]{:\implies \quad \displaystyle \int \sf \dfrac{\cos^{2}(x)}{1+\sin (x)}dx}[/tex]
As we know that sin²(x) + cos²(x) = 1 , using this
[tex]{:\implies \quad \displaystyle \int \sf \dfrac{1-\sin^{2}(x)}{1+\sin (x)}dx}[/tex]
Can be further written as
[tex]{:\implies \quad \displaystyle \int \sf \dfrac{1^{2}-\sin^{2}(x)}{1+\sin (x)}dx}[/tex]
[tex]{:\implies \quad \displaystyle \int \sf \dfrac{\cancel{\{1+\sin (x)\}}\{1-\sin (x)\}}{\cancel{\{1+\sin (x)\}}}dx\quad \qquad \{\because a^{2}-b^{2}=(a+b)(a-b)\}}[/tex]
[tex]{:\implies \quad \displaystyle \int \sf \{1-\sin (x)\}dx}[/tex]
Now , as integrals follow distributive property , so ;
[tex]{:\implies \quad \displaystyle \int \sf 1\: dx-\int \sin (x)dx}[/tex]
Now , as antiderivative (Integration) of sin(x) is -cos(x) + C and that of dx is x + C So ;
[tex]{:\implies \quad \displaystyle \bf \therefore \underline{\underline{\int \bf \dfrac{\cos^{2}(x)}{1+\sin (x)}=x+\cos (x)+C}}}[/tex]
