Please help me asp I really need help
Neporo4naja [7]

Answer:

Following the rules the coordinate pairs are: (1,0), (5,1), (17,3), (53,7), (161,15)

Step-by-step explanation:

Nicole's Pattern: Multiply by 3 then add 2, starting from 1

Ion's Pattern: Add 1/2 then multiply by 2 starting from 0

So, Nicole's pattern is generated starting from 1, we multiply by 3 and then add 2 to get the next number

While Ion's pattern is generated starting from 0, we add 1/2 to it and then multiply by 2 to get the next number

Nicole's Pattern               Ion's Pattern          Coordinate pairs

1                                          0                               (1,0)

5                                          1                                (5,1)

17                                         3                              (17,3)

53                                        7                               (53,7)

161                                        15                              (161,15)

PLEASE HELP ME I NEED THIS DONE TODAY PLEASE HELP I KNOW NO ONE WILL BUT IT'S 7TH GRADE MATH PLEASE HELP
Andrei [34K]

Answer:

Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)

Step-by-step explanation:

First you have to do all the Distributive property which the answer would be:

2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18

Then you have to find the common demoninator which would be 18

After that you have to put them in the correct order since there is two different terms which would be:

2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x

After that you solve the problem which in the end after solving both terms it ends up as..:

10 2/18 - 1 5/18x

and I think that is as simplified as you can go term wise.

I hope this helps and I hope I didn't make a mistake :D

Ira Lisetskai [31]

Answer: 95% confidence interval would be (0.344,0.456).

Step-by-step explanation:

Since we have given that

n = 295

x = 118

so, \hat{p}=\dfrac{x}{n}=\dfrac{118}{295}=0.4

At 95% confidence, z = 1.96

So, margin of error would be

z\times \sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.4\times 0.6}{295}}\\\\=0.056

so, 95% confidence interval would be

\hat{p}\pm \text{margin of error}\\\\=0.4\pm 0.056\\\\=(0.4-0.056,0.4+0.056)\\\\ =(0.344,0.456)

Hence, 95% confidence interval would be (0.344,0.456).
