The lengths of salamanders have a normal distribution with mean 15cm, and standard deviation 2cm. What length of salamander woul

Law Incorporation [45]

Answer:

16.68 cm

Step-by-step explanation:

Given that :

Mean , m = 15

Standard deviation, s = 2

Length of salamander that would Place it at 80% of salamander length :

P(Z ≤ x) = 0.8

Zscore equivalent to 0.8 = 0.842

Using the relation :

Zscore = (x - m) /s

0.842 = (x - 15) / 2

1.684 = x - 15

Add 15 to both sides

1.684 + 15 = x - 15 + 15

16.684 = x

Hence, x = 16.68 cm

Step-by-step explanation

- 7(6x-1)+x=36

=> 42x - 7 + x = 36
=> 43x - 7 = 36
=> 43x = 36 + 6 = 43
=> x = 43 / 43 = 1

- 11-2(8+3p)=7²

=> 11 - 16 - 6p = 7^2
=> 11 - 16 - 6p = 49
=> -5 - 6p = 49
=> -6p = 49 + 5 = 54
=> p = (54) / (-6) = - 9

- 1/4(5b+11)=19

=> (5/4)b + (11/4) = 19
=> (5/4)b = 19 - (11/4) = 65 /4
=> b = (65/4) / (5/4) => (65/4) * (4/5) = 13

- 2/7(4m-18)=12

=> (8/7)m - (36/7) = 12
=> (8/7)m = 12 + (36/7) = 120/7
=> m = (120/7) / (8/7) = 120 /8 = 15
