Answer:

There are no real number solutions to this.

Step-by-step explanation:

x + y = 27

xy = 365

y = 365/x

x + 365/x = 27

x^2 + 365 = 27x

x^2 - 27x + 365 = 0

x = [27 +/- sqrt(27^2 - 4 * 1 * 365)] / 2

x = (27 +/- sqrt (-731)/2

- No real roots.

Write the equation of a line perpendicular to 5x - 7y =-6 that passes through the point (-5,6)
Likurg_2 [28]

9514 1404 393

Answer:

  7x +5y = -5

Step-by-step explanation:

You can find the perpendicular line by swapping the x- and y-coefficients, and negating one of them. The new constant can be found by using the given point.

  7x +5y = 7(-5) +5(6) = -5

The perpendicular line through (-5, 6) is ...

  7x +5y = -5

Hitman42 [59]

Answer:

The probability that a radio selected at random will last from 600 to 700 hours is 0.3413

Step-by-step explanation:

The playing life of a Sunshine radio is normally distributed

Mean =\mu = 600 hours

Standard deviation =\sigma = 100 hours

We are supposed to find the probability that a radio selected at random will last from 600 to 700 hours i.e.P(600<x<700)

Formula:Z= \frac{x-\mu}{\sigma}

At x = 600

Z= \frac{600-600}{100}

Z=0

P(X

At x = 700

Z= \frac{700-600}{100}

Z=1

P(X

P(600

Hence the probability that a radio selected at random will last from 600 to 700 hours is 0.3413
