Hello!

The mean is 86 and the standard deviation is 3

You see how many deviations are between 86 and 89

86 + 3 = 89

From the median to the first deviation is where 34.1% of the results fall

Convert the percent to a decimal

34.1% = 0.341

Multiply this by the amount of test taken

200*0.341 = 68.2

The answer is B)68

Hope this helps!

Pavel [41]

Answer:

  46 cm

Step-by-step explanation:

Let p represent the length in cm of 1 bap'ai; let k represent the length in cm of 1 bok'ai. Then we have ...

  12p +2k = 100

  10p +10k = 100

Subtracting the second equation from 5 times the first, we get ...

  5(12p +2k) -(10p +10k) = 5(100) -(100)

  50p = 400

  p = 8 . . . . cm

Then the second equation tells us ...

  10(8) +10k = 100

  10k = 20

  k = 2 . . . . cm

Then 5p+3k = 5(8) +3(2) = 46 cm.

The distance 5 bap'ai and 3 bok'ai is 46 cm.
