Graph the line of the equation 8x/5 - 2y = -8 using its slope and y-intercept
satela [25.4K]

Answer:

y=\frac{4}{5}x+4

Step-by-step explanation:

You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.

\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4

Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.

When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey t
Vlada [557]

Answer: 601

Step-by-step explanation:

The formula to find the minimum sample size(n) , if the prior population proportion is unknown:

n=0.25(\dfrac{z^c}{E})^2, where E = margin of error , z^c = critical z-value for confidence level c.

Given : E  = 0.04

Z-value for 95% confidence = 1.96

So, the minimum sample size required = 0.25(\dfrac{1.96}{0.04})^2=0.25(49)^2

= 0.25\times 2401=600.25\approx601

Hence, the minimum sample size required = 601
