Solve: 3n - 6 = -8(6 +5n)<br> and explain how to solve it

hjlf

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

43n = -42

n = -42 /43

Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence i

mash [69]

Complete Question

A biologist reports a confidence interval of (3.5,4.9) when estimating the mean height (in centimeters) of a sample of seedlings. What is the estimated margin of error and the sample mean?

Answer:

The margin of error is $E = 0.7$

The sample mean is $\= x = 4.2$

Step-by-step explanation:

from the question we are told that

The upper limit is $k = 4.9$

The lower limit is $r = 3.5$

Generally the margin of error is mathematically represented as

$E = \frac{k - r}{ 2}$

$E = \frac{ 4.9 - 3.5 }{2}$

$E = 0.7$

Generally the sample mean is mathematically evaluated as

$\= x = k - E$

=> $\= x = 4.9 - 0.7$

=> $\= x = 4.2$
