Write the slope intercept equation of a line that passes through points (-3,4) and (2, -6)

Setler [38]

Find slope by calculating rise over run.
-6-4 / 2-(-3)
-10/5
-2

Then plug one set of coordinates and the slope in to find the b value
-6= -2(2)+b
-6=-4+b
-2=b

Final answer: y=-2x-2

Airida [17]

Answer:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

For this case the confidence interval is given by (6.55,8.15). And we can estimate the margin of error with this formula since the confidence interval is symmetrical:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$

Step-by-step explanation: CZ 75B has a firing pin block which makes for a longer SA trigger pull. CZ 75 has the superior trigger. Aren't the magazines different (and not interchangeable) as well? IIRC, the older 75 mags are not easy to find, and can be expensive.Apr 22, 2011
