Order the numbers in each list from least to greatest. 0, |-14|, 13 , -12, |-16|, 17

jeka57 [31]

Here is your answer:

In order to find the answer you must first find the absolute value of each number, then order them from least to greatest.

$0 = 0$
$I-14I = 14$
$13 = 13$
$-12 = 12$
$I-16I=16$
$17 = 17$
Now least to greatest:
$-12,0,13,14,16,17$

Therefore the answer is "-12,0,13,14,16,17."

Hope this helps!

A GROUP OF STATISTICS STUDENTS DECIDED TO CONDUCT A SURVEY AT THEIR UNIVERSITY TO FIND THE AVERAGE (MEAN) AMOUNT OF TIME STUDENT

Kay [80]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

n = 240

mean = 22.3 hours

standard deviation = 6 hours

At 99% level of confidence, z = 2.58

So, interval would be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=22.3\pm 2.58\times \dfrac{6}{\sqrt{240}}\\\\=22.3\pm 0.99\\\\=(22.3-0.99,22.3+0.99)\\\\=(21.31,23.29)$

Hence, Option 'c' is correct.
