Let's factor the following polynomial to find the roots:
 x2-13x + q = 0
 Factoring we have:
 (x-12.5) * (x + a)
 Where,
 -12.5 + a = -13
 a = -13 + 12.5
 a = -0.5
 We now look for the coefficient q:
 q = -12.5 * a
 q = -12.5 * (- 0.5)
 q = 6.25
 The polynomial will then be:
 x2-13x + 6.25 = 0
 Its roots are:
 x1 = 12.5
 x2 = 0.5
 Answer:
 The other root and the value of the coefficient are:
 0.5 and 6.25 (Respectively)

​Recently, a random sample of 13-18 year olds was​ asked, "How much do you currently have in​ savings?" The data in the table re
Sonbull [250]

Answer:

μ = 235.38

σ = 234.54

Step-by-step explanation:

Assuming the table is as follows:

\left[\begin{array}{cc}Savings&Frequency\\\$0-\$199&339\\\$200-\$399&86\\\$400-\$599&55\\\$600-\$799&18\\\$800-\$999&11\\\$1000-\$1199&8\\\$1200-\$1399&3\end{array}\right]

This is an example of grouped data, where a range of values is given rather than a single data point.  First, find the total frequency.

n = 339 + 86 + 55 + 18 + 11 + 8 + 3

n = 520

The mean is the expected value using the midpoints of each range.

μ = (339×100 + 86×300 + 55×500 + 18×700 + 11×900 + 8×1100 + 3×1300) / 520

μ = 122400 / 520

μ = 235.38

The variance is:

σ² = [(339×100² + 86×300² + 55×500² + 18×700² + 11×900² + 8×1100² + 3×1300²) − (520×235.38²)] / (520 − 1)

σ² = 55009.7

The standard deviation is:

σ = 234.54
