The Cartesian coordinate system is also known as a rectangular coordinate system and it is done on two coordinate axes that are perpendicular to each other.

<h3>What is a distance-time curve?</h3>

The distance-time curve can be plotted on the rectangular coordinate axis with distance on the y-axis while the time will be on the x-axis. The slope of the s-t curve gives velocity while v-t curve will give acceleration.

In the rectangular coordinate system, the points are of the form (x,y) but in the case of polar coordinates, the point on the circle will be denoted by (rcosθ,rsinθ) where 'r' is the radius of the circle.

soldi70 [24.7K]

Answer:

The teacher select a sample of n =15 students.  And he wanted to know if teaching a smaller class was more effective and students performed better, that means if \mu >78 and he obtaind a sample mean of \bar X>83.

Based on this the correct system of hypothesis are:

Null hypothesis: \mu =78

Alternative hypothesis: \mu >78

And the best option for this case is:

a. H0:\mu=78 vs. H1:\mu>78 .

Step-by-step explanation:

For this case we have the following previous info given:

\mu = 78 represent the true mean

\sigma =10 represent the true deviation

The teacher select a sample of n =15 students.  And he wanted to know if teaching a smaller class was more effective and students performed better, that means if \mu >78 and he obtaind a sample mean of \bar X>83.

Based on this the correct system of hypothesis are:

Null hypothesis: \mu =78

Alternative hypothesis: \mu >78

And the best option for this case is:

a. H0:\mu=78 vs. H1:\mu>78 .

????????????????????????????
viktelen [127]

Answer:

The inverse is 5x+3

Step-by-step explanation:

y = (x-3) /5

Exchange x and y

x = (y-3)/5

Solve for y

Multiply each side by 5

5x =(y-3)/5 *5

5x = y-3

Add 3 to each side

5x+3 =y-3+3

5x+3 =y

The inverse is 5x+3
