A physical fitness association is including the mile run in its secondary-school fitness test. The time for this event for boys

jek_recluse [69]

Answer:

The boys need to complete the run in 385.9 seconds or less in order to earn a certificate of recognition from the fitness association.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 450

Standard Deviation, σ = 50

We are given that the distribution of time for fitness test is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.10

P(X<x) = 0.10

$P( X < x) = P( z < \displaystyle\frac{x - 450}{50})= 0.10$

Calculation the value from standard normal z table, we have,

$P(z\leq -1.282) = 0.10$

$\displaystyle\frac{x - 450}{50} = -1.282\\\\x = 385.9$

Hence, boys need to complete the run in 385.9 seconds or less in order to earn a certificate of recognition from the fitness association.

Please help meeeeee I will mark you!. I need an answer and explanation

kari74 [83]

Answer:

12^2 + x^2 = 13^2

Step-by-step explanation:

The student's error was that he didn't use the Pythagorean Theorem correctly

According to the Pythagorean Theorem, a^2 + b^2 = c^2, where c represents the hypotenuse

However, the student replaced c with x, which isn't the hypotenuse

The hypotenuse is 13, so c should be 13, not x
