3n-5=-48-40n. Please help . I need the steps to solve and the answer

liraira [26]

3n-5=-48-40n

Move -40n to the other side. Sign changes from -40n to +40n.

3n+40n-5=-48= -48-40n+40n

3n+40n-5=-48

Move -5 to the other side.

3n+40n-5+5=-48+5

3n+40n=-43

43n=-43

Divide by 43 for both sides

43n/43=-43/43

n=-1

Answer: n=-1

Answer:

$\mu_{p}=p=0.81$

Step-by-step explanation:

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".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

So under the null hypothesis the mean for the population proportion is p

$\mu_{p}=p=0.81$

And the standard deviationis given by:

$\sigma_{p}=\sqrt{\frac{p_0(1-p_o)}{n}}=\sqrt{\frac{0.81(1-0.81)}{1000}}=0.0124$

How to find slope on a graph?

GalinKa [24]

Well you basically use rise/run so basically you choose two points on the line and you count how many squares it goes up until its on the same line as the other point and then you count how many squares to the side to get to the other point so rise/run ill explain it a lil better
