A certain high school class consists of juniors and seniors. There are
Genrish500 [490]

Answer:

10 SENIORS

Step-by-step explanation:

x=# of seniors

y=# of juniors

x+y=23, x=2y-7

  1. plug the value of x in the second equation into the first
  2. (2y-7)+y=23
  3. Remove parentheses
  4. 2y-7+y=23
  5. Combine like terms
  6. 3y-7=23
  7. Add 7 to BOTH sides
  8. 3y=30
  9. divide BOTH sides by 3
  10. 3y/3=30/3
  11. y=10
  12. There are 10 juniors in the class
  1. FINAL STEPS
  2. Plug y (which is 10) into the first equation
  3. x+y=23
  4. x+10=23
  5. subtract 10 from BOTH sides
  6. x=13
  7. Since X equals the number of seniors, there are 10 seniors in the class

find the standard deviation for this data set 9, 15, 13, 9, 15 round your answer to the nearest tenth
KatRina [158]

Answer:

  • 3.0

Step-by-step explanation:

Sample standard deviation is found by steps below.

<u>Find the mean:</u>

  • μ = (9 + 15 + 13 + 9 + 15)/5 = 12.2

<u>Find deviations from the mean and their squares:</u>

  • 9 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.24
  • 15 - 12.2 = 2.8 ⇒ 2.8² = 7.84
  • 13 - 12.2 = 0.8 ⇒ 0.8² = 0.64
  • 9 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.24
  • 15 - 12.2 = 2.8 ⇒ 2.8² = 7.84

<u>Sum the squares:</u>

  • 10.24*2 + 7.84*2 + 0.64 = 36.8

<u>Divide by N - 1 (N - number of samples):</u>

  • 36.8/(5 - 1) = 9.2

<u>Square root is the sample standard deviation:</u>

  • σ = √9.2 = 3.0 (rounded)
