When the reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller, the

yawa3891 [41]

Answer: No solution

<u>Step-by-step explanation:</u>

1st number: x

2nd number: x + 2

reciprocal of the larger is $\frac{1}{x+2}$

4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$

reciprocal of the larger of two consecutive even integers is subtracted from 4 times the reciprocal of the smaller is 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$

the result is 56: 4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

Solve the equation:

4 $(\frac{1}{x})$ - $\frac{1}{x+2}$ = 56

$\frac{4(x(x + 2))}{x}$ - $\frac{1(x(x + 2))}{x+2}$ = 56(x(x + 2))

4x + 8 - x = 56x² + 112x

3x + 8 = 56x² + 112x

0 = 56x² + 109x - 8

Use the quadratic formula to solve:

x = $\frac{-109+/-11\sqrt{113}}{112}$

The result is NOT AN INTEGER so there is NO SOLUTION

You are in charge of monitoring the pressure of a compressed air tank in a processing plant. After repeating the pressure measur

Anastasy [175]

Answer:

11.5

Step-by-step explanation:

Given that :

I am in charge of the pressure reading in a compressed air tank of a processing plant.

The Gaussian distribution having a mean value = 69 psi

Standard deviation = 10 psi

Here we have to find the probability that the pressure will exceed 84 psi.

So,

$P(X \geq 84) = P \left(\frac{X - 69}{10} > \frac{84-69}{10} \right)$

$=P(Z > 1.5)$

$=1-P(Z < 1.5)$

= 0.115

= 11.5
