Answer:

See below

Step-by-step explanation:

\sqrt[3]{49}  = 3.65930571002 \approx3.66 \\  \\ so \:  \sqrt[3]{49} should \: lie \: at \: 3.6 \: which \:  \\ fall \: between \: 3 \: and \: 4.

Actually Lin did a mistake, she obtained square root and not cube root.

Answer with Explanation:

  • 3\sqrt{49} should be placed<u> in-between 3 and 4</u> on the number line (a little bit approaching number 4). The cube root of 49 is 6.66. Therefore, <em>it shouldn't be placed on number 7.</em>

  • Lin thought that she was asked to get the<em> square root of 49</em>, which looks like this: \sqrt{49}. Probably, she missed the number 3. It was actually asking for the<em> cube root of 49</em>. This is also the reason why she placed the dot on the number 7 because the<em> square root of 49 is 7</em>.

Let p=x^2+6
stepan [7]
That's a bit of a nasty. Where ever you see (x^2 + 6) you put in p.
p^2  - 21 = 4(x^2 + 6)
p^2 - 21 = 4p
p^2 - 4p - 21 = 0

The median of the set (n, n+5, n+6, n+9, n+15) is 9. What is the mean?
Simora [160]

Answer:

   =9.4

Step-by-step explanation:

The median  is the middle of the numbers when lined up from smallest to largest

(n, n+5, n+6, n+9, n+15)

The median is n+6

n+6 = 9

Subtract 6 from each side

n +6-6 = 9-6

n = 3

The numbers are

(n, n+5, n+6, n+9, n+15)

3, 8 ,9 ,12, 15

The mean is where you add up all the numbers and divide by the number of numbers

mean = (3+8+9+12+15) /5

         = (47)/5

         = 9 2/5

        =9.4
