52+4y=12

We move all terms to the left:

52+4y-(12)=0

We add all the numbers together, and all the variables

4y+40=0

We move all terms containing y to the left, all other terms to the right

4y=-40

y=-40/4

y=-10

3.1-3y=18

We move all terms to the left:

3.1-3y-(18)=0

We add all the numbers together, and all the variables

-3y-14.9=0

We move all terms containing y to the left, all other terms to the right

-3y=14.9

y=14.9/-3

y=-4+2.9/3

Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,

Sedaia [141]

Answer:

The confidence interval is $0.304 < p < 0.324$

Step-by-step explanation:

From the question we are told

The sample proportion $\r p = 0.314$

The margin of error is $E = 0.01$

The confidence interval for p is mathematically represented as

$\r p - E < p < \r p + E$

=> $0.314 - 0.01 < p < 0.314 + 0.01$

=> $0.304 < p < 0.324$

Suppose M is the midpoint

AysviL [449]

x = 9

Since M is the midpoint of XY:

XM = MY

XM = 2x + 11

MY = 5x - 16

2x + 11 = 5x - 16

5x - 2x = 11 + 16

3x = 27

x = 27/3

x = 8
