Answer:

Length of old board = 68.2cm

Step-by-step explanation:

Let old board length be x

Given new board is 120 % longer than old board = x + 120% of x

Length of new board = 150cm

Therefore,

x + 120% of x = 150

$x + \frac{120}{100} x = 150\\\\x + 1.20x = 150\\\\2.2x = 150 \\\\x = 68.18 = 68.2cm$

The Ransin Sports Company has noted that the size of individual customer orders is normally distributed with a mean of $112 and

Mashutka [201]

Answer: 2.71

Step-by-step explanation:

We know that the formula to calculate the standard error is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ is the standard deviation and 'n' is the sample size.

Given : Standard deviation : $\sigma=\$9$

Sample size : $n=11$

Then , the standard error of the mean is given by :-

$S.E.=\dfrac{9}{\sqrt{11}}=2.7136021012\approx2.71$

Hence, the standard error of the mean = 2.71
