8. what is the graph of the inequality in the coordinate plane? <br><br> y<-2

LekaFEV [45]

1) Draw the coordinate plane

2) Draw the line y = - 2

It is a line parallel to the y axis, two units below the origin

3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.

What is the inverse of the function f(x) = x + 2?

wolverine [178]

Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.

A newspaper article states that 90% of drivers in Iowa wear their seatbelt. Suppose we are interested in estimating the proporti

Answer:

The sample size is $n = 3457$

Step-by-step explanation:

From the we are told that

The population proportion is p = 0.90

The margin of error is E = 0.01

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally the sample size is mathematically represented as

$n =[ \frac{ Z_{\frac{\alpha }{2} } }{E} ]^2 * p(1-p)$

=> $n =[ \frac{ 1.96 }{0.01} ]^2 * 0.90(1-0.90)$

=> $n = 3457$

Expanding and Adding Expressions Use the expansion shown to simplify the expression. One-half (3 x minus two-thirds y) + 3 (Star

Lisa [10]

Answer:

$3x+\frac{7}{6}y$

Step-by-step explanation:

To simplify the expression, we first open the parenthesis, then we collect all the like terms. Lastly we simplify the like terms to its simplest form. Given that:

$\frac{1}{2}(3x-\frac{2}{3} y)+3(\frac{x}{2}+\frac{1}{2}y )\\\\Firstly, we\ expand\ the\ parenthesis:\\\\=\frac{1}{2}(3x)-\frac{1}{2}(\frac{2}{3} y)+3\frac{x}{2}+3(\frac{1}{2} y)\\$

$=\frac{3}{2}x-\frac{1}{3}y +\frac{3}{2}x+\frac{3}{2} y\\\\ Collecting\ like\ terms:\\\\=\frac{3}{2}x+\frac{3}{2}x-\frac{1}{3}y+\frac{3}{2}y\\\\Adding \ terms:\\\\=3x +\frac{7}{6}y$
