3+2k= -4(k+4) i need help

Rom4ik [11]

Answer:

k = -19/6

This picture should help you out.

First you distribute -4 among everything in the parenthesis. You will get -4k - 16.

Next you subtract 3 from -16, to get -19.

After that you add 4k to 2k, to get rid of -4k, and you get 6k.

So 6k = -19, and finally you divide 6 on both sides of the equal sign to get k = -19/6.

Hope this helped :)

Answer:

Standard error for the proportion of social media users who are concerned about privacy

S.E = 0.0219

Step-by-step explanation:

Explanation:-

Given data recent survey of 500 social media users, 300 stated that they were concerned about privacy

Size of random sample 'n' = 500

x = 300

sample proportion $p = \frac{x}{n} = \frac{300}{500} = 0.6$

Standard error for the proportion of social media users who are concerned about privacy is determined by

$S.E = \sqrt{\frac{p(1-p)}{n} }$

$S.E = \sqrt{\frac{0.6(1-0.6)}{500} }= 0.0219$

So divide 1.89 by 6 to see how much would one pound of grape be
1.89/6=0.315
Then multiply 0.315 (price for one pound of grape ) by 15
0.315*15 =4.725 $for 15 pounds of grape
