Answer:

parallel lines

Step-by-step explanation:

If two lines are parallel it means that they never intersect

the only way for this to happen is when the slopes are identical (and the y intercepts are different)

This is the case

find the slope and y intercept for the following equation by writing it in the form y=mx+b -8x+y=5 someone help please

vichka [17]

Answer:

slope = 8, y- intercept = 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Given

- 8x + y = 5 ( add 8x to both sides )

y = 8x + 5 ← in slope- intercept form

with slope m = 8 and y- intercept c = 5

Legalize Marijuana, Part II. As discussed in Exercise 6.12, the 2010 General Social Survey reported a sample where about 48% of

kvv77 [185]

Answer:

Around 2397 Americans must be surveyed to get a margin of error of 2%.

Step-by-step explanation:

We are given the following in the question:

Proportion of US residents who thinks marijuana should be made legal = 48%

$\hat{p} = 0.48$

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.48(1-0.48)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.48(1-0.48)}}{0.02}\\\\\sqrt{n}=48.96\\n = 2397.0816\approx 2397$

Thus, around 2397 Americans must be surveyed to get a margin of error of 2%.

60 + 6 equals 13 + 5 p

Lilit [14]

60+6=13+5p

66=13+5P

66-13=5p

57=5p

p=57/5

...p= 10.14
