ASAP Which diagram shows the correct setup for an electromagnet?

castortr0y [4]

What do you notice about each solution? :
Picture 1 - They never intersect/touch.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other.

What do you notice about the graphs for each set of equations? :
Picture 1 - The lines are parallel.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other. (otherwise known as coincident lines).

What do you notice about each set of equations? :
Picture 1 - They have the same slope but different y-intercepts.
Picture 2 - Both the slopes and y-intercepts are different for each equation.
Picture 3 - They have the same slope and same y-intercept.

What generalization can you make? :
Picture 1 - When equations have the same slope but different y-intercepts they will be parallel when graphed.
Picture 2 - When the equations have different slopes and different y-intercepts they will be intersecting.
Picture 3 - When the equations are the same they will be coincident lines when graphed.

A statistics professor gives a survey to each of the 20 students in an introductory statistics course. The survey asks the stude

tekilochka [14]

Answer:

$B2 = 0.465$ --- Population standard deviation

$C2 = 0.216$ --- Population Variance

Step-by-step explanation:

Given: Wake-up time data

Required: Determine the population standard deviation and the population variance using Excel

First, enter the given data in Excel

For this question, I entered the data in cell A2 through cell A21

Cell B2 and Cell C2 were used to hold the results of the population standard deviation and the population variance, respectively.

In cell B2, the formula to use is:

=ROUNDUP(STDEV.P(A2:A21),3)

The round function rounds the result to 3 decimal places while STDEV.P calculates the population standard deviation.

So, the result is:

$B2 = 0.465$

In cell C2, the formula to use is:

=ROUND(VAR.P(A2:A21),3)

The round function rounds the result to 3 decimal places while VAR.P calculates the population variance.

So, the result is:

$C2 = 0.216$

Please show work for number 3 and 4!

svetoff [14.1K]

Answer:

Three: x = 400

Four : 9

Step-by-step explanation:

Three

a = 10*√2

2a = √(2x) Square both sides.

4a^2 = 2x Divide both sides by 2

2a^2 = x Put a = 10√2 into a^2

2(10√2)^2 = x Square a

2(100*2) = x Multiply the result by 2.

2(200) = x

x = 400

Four

x^(a^2) / x ^(b^2) = x^36

Substitute a + b = 4 in for b.

x^(a^2) / x^(4 - a)^2 = x^36

Subtract powers

x^(a^2 - (4 - a)^2 = x^36

x^(a^2 - (16 - 8a + a^2) = x^36

Gather like terms

x^(8a - 16) = x^36

The powers are now equal

8a - 16 = 36

Add 16 to both sides

8a = 36 + 16

8a = 52

Divide by 8

a = 6.5

Solve for b

a + b = 4

6.5 + b = 4

b = 4 - 6.5

b = - 2.5

a - b = 6.5 - (- 2.5) = 9
