In order to estimate the mean amount of time computer users spend on the internet each​ month, how many computer users must be s
levacccp [35]

Answer:

1877 computer users

Step-by-step explanation:

We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.

We apply the following formula:

n = [z * sd / E] ^ 2

replacing:

n = [1.96 * 221/10] ^ 2

n = 1876.27

that is, the minimum sample size is 1877

PLSSS HELP!! For the given ordered pairs, write a function rule relating x and y. (1,4), (2,9), (3,16), (4,25)​
LenKa [72]

Answer:

y=(x+1)^2

Step-by-step explanation:

we have the following

x=1;y=4\\\\x=2;y=9\\\\x=3;y=16\\\\x=4;y=25

the values of y are squares so we can write

x=1;y=2^{2} \\\\x=2;y=3^2\\\\x=3;y=4^2\\\\x=4;y=5^2

so as you can see when

x=n;y=(n+1)^2

so our relation is

y=(x+1)^2
