Answer:

z = ( 135 - μ ) / σ = -1

z = ( 165 - μ ) / σ = 1

P (x < 135) = P (z < -1) = 0.1587

P (165 < x) = P (1 < z) = 0.1587

.187 * 1000 = 187 more than 165

.187 * 1000 = 187 less than 135

kondor19780726 [428]

Answer:

Yes, you are correct.

Step-by-step explanation:

$\text{Let the number of puzzle solved by Child B is} x\text{.}$

$\text{Then the average number of puzzle solved is}$

$\frac{5x+x+(x+4)}{3}=13$

$\frac{7x+4}{3}=13$

$7x+4=39$

$7x=35$

$x=5$

$\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25$

$\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}$
