1. There are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. The first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. The line plot shows the differences after 10 rerandomizations. Determine whether the difference in the means of the two groups is significant based on the line plot. Explain your answer.

Answers

the answer is attached below

Answer:

the difference  in the means is not significant

Step-by-step explanation:

Let’s begin first by finding the difference between the means of the 2 groups.

Difference in means = 95% - 92% = 3%  Now  let’s look at  the line plot of the 10 rerandomizations.   On that plot, 4 of the randomizations have a difference of 3.  

Probability of having a difference of 3 = 4 / 10 *100%  = 40%  

So just by mixing up the scores from both classes and finding the difference between the mean of 2 randomly defined groups, there was a difference of 3 between the 2 means in 40%  of the trials.

Since this probability is so large, the difference in the means is not significant.  The line plot shows that it would be very likely that the difference in the means is just due to random chance

Find the real-number root.001O no real rootsO 0.1O 0.1 and 0.1O 0.1 I need help

Answers

for cube roots of a positive number, it could have a real number of a negative number but has to contain 2 negatives if it does and one positive. Eg. (-)*(-)* (+) = +

0.001 can be made by multiplying 3 0.1's (0.1^3)
However, we are finding the root here so my explanation above tells us that a cuberoot of a positive number is never a negative.

So the answer is 0.1
0.1

0.1^3 = 0.1*0.1*0.1 = 0.01*0.1 = 0.001

Help me solve this problem. quick !!!
thank you!!!!!

The equation for calculating

P = 2L + 2W

instead of letters L and enter the values ​​given numbers

L = 2 (1)/(2) 

W = 3 (2)/(5) 

1 way

P = 2 * 2 (1)/(2) + 2 * 3 (2)/(5) \n \n P = (2)/(1) * (5)/(2) + (2)/(1) * (17)/(5) \n \n P = 1 * 5 + (34)/(5) \n \n P = 5 + 6 (4)/(5) = 11 (4)/(5) 

2 way

P = 2L + 2W = 2 * (L + W) = 2 * (2 (1)/(2) + 3 (2)/(5) ) = 2 * ( 2 (5)/(10) + 3 (4)/(10) ) = 2 * 5 (9)/(10) = (2)/(1) * (59)/(10) = 1 * (59)/(5) = 11 (4)/(5)

What is the solution to the equation?2 - z/3 =12


A.
z = –42

B.
z = –34

C.
z = –30

D.
z = 42

Answers

2 - z/3 = 12

Subtract 2 to both sides:

-z/3 = 10

Multiply 3 to both sides:

-z = 30

Multiply -1 to both sides:

z = -30
First, add 2 to both sides, and you get z/3 = 14. Then multiply 3 to both sides. 3 x 14 = 42, so we have z = 42. :)
