Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy<br> (solve for x)

Fed [463]

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

The average college lecture hall (auditorium) can seat 60 students with a standard deviation of 21. Assume that a total of 60 le

fiasKO [112]

Answer:

The standard deviation of the sample mean is $\sigma _ {\= x } = 2.711$

Step-by-step explanation:

From the question we are told that

The mean is $\= x = 60$

The standard deviation is $\sigma = 21$

The sample size is $n = 60$

Generally the standard deviation of the sample mean is mathematically represented as

$\sigma _ {\= x } = \frac{\sigma }{\sqrt{n} }$

substituting values

$\sigma _ {\= x } = \frac{ 21 }{\sqrt{60} }$

$\sigma _ {\= x } = 2.711$
