today at basketball practice the team worked on three skills. they ran for 22 minutes, they did passing drills for 35 minutes. they practiced shooting free throws for 27 minutes. tomorrow the coach wants the team to spend an equal amount of time on each drill. if the team spends the same total number of minutes on these 3 drills as today, how many minutes will the team spend on each drill
Answer:
28
Step-by-step explanation:
So first you need to add up the time they played yesterday which means add up the times for each drill(22+35+27) which equals 84. Now you need to divide 84 by 3 because there are 3 drills(84÷3) which equals 28 and you will get your answer
22 + 35 + 27 = 84 ÷ 3 = 28
Hope this helps

What is the equation of the line that passes through the point (-7,8) and has a slope of -1?
What matches with the number line?
The larger the negative number gets, the farther from zero it becomes. -9.8 is closer to zero- therefore "larger" than -11.3.

Please help me! A dealership recently sold a 4-door sedan, which it purchased for $18,000, at 15% markup. It accepted a trade-in for it, and it paid $5000 for the trade. Next, it marked the trade-in up 25% and sold it in a week. What was the dealership's profit on these two vehicles?
Step-by-step explanation:
The answer is 3950 $
First we will calculate the two profits the dealership earned.
1. Profit on purchase.
18000 x 15% = 18000 x 0.15
=2700 $
2. Profit on Sale:
5000 x 25% = 5000 x 0.25
= 1250$
3. Adding both profits:
Total profit = 2700 + 1250 = 3950 $

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]

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.

Write the equation of the line through the given points :
I need help please
Answer:
[tex]y=-3x+5[/tex]
Step-by-step explanation:
The equation for slope is:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can substitute the given coordinates into the equation:
[tex]Slope=\frac{3-0}{\frac{2}{3}-\frac{5}{3}}=\frac{3}{\frac{2-5}{3}}=\frac{3}{\frac{-3}{3}}=\frac{3}{-1}=-3[/tex]
The slope is -3
The equation for a line is:
[tex]y=mx+b[/tex]
m: slope
b: y-intercept
x, y: (x, y) coordinate pair
Now, plug in the slope and one of the (x, y) coordinate pairs to solve for the y-intercept.
[tex]y=mx+b\\y=-3x+b\\0=-3(\frac{5}{3})+b\\0=\frac{-15}{3}+b\\0=-5+b\\$Add 5 to both sides\\b=5[/tex]
Therefore the equation is:
[tex]y=-3x+5[/tex]

The overhead reach distances of adult females are normally distributed with a mean of 205.5 cm and a standard deviation of 7.8 cm. a. Find the probability that an individual distance is greater than 218.00 cm. b. Find the probability that the mean for 25 randomly selected distances is greater than 204.20 cm. c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? a.
Using the normal distribution, we have that:
a) There is a 0.0548 = 5.48% probability that an individual distance is greater than 218.00 cm.
b) There is a 0.7967 = 79.67% probability that the mean for 25 randomly selected distances is greater than 204.20 cm.
c) Since the underlying distribution is normal, the central limit theorem can be applied.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], as long as the underlying distribution is normal or the sample size is greater than 30.For this problem, the parameters are:
[tex]\mu = 205.5, \sigma = 7.8, n = 25, s = \frac{7.8}{\sqrt{25}} = 1.56[/tex]
Item a:
The probability is one subtracted by the p-value of Z when X = 218, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{218 - 205.5}{7.8}[/tex]
Z = 1.6
Z = 1.6 has a p-value of 0.9452.
1 - 0.9452 = 0.0548.
There is a 0.0548 = 5.48% probability that an individual distance is greater than 218.00 cm.
Items b and c:
Since the underlying distribution is normal, the central limit theorem can be applied, hence the probability is one subtracted by the p-value of Z when X = 204.2.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{204.2 - 205.5}{1.56}[/tex]
Z = -0.83
Z = -0.83 has a p-value of 0.2033.
1 - 0.2033 = 0.7967.
There is a 0.7967 = 79.67% probability that the mean for 25 randomly selected distances is greater than 204.20 cm.
