Weights of American adults are normally distributed with a mean of 180 pounds and a standard deviation of 8 pounds. What is the

Leto [7]

Answer:

There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds

Step-by-step explanation:

Z score

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where μ is the mean, x = raw score and σ is the standard deviation.

Given μ = 180, σ = 8.

For x = 185:

z = (185 - 180)/8 = 0.625

For x = 190:

z = (190 - 180)/8 = 1.25

P(185 < x < 190) = P(0.625 < z < 1.25) = P(z < 1.25) - P(z < 0.625) = 0.8944 - 0.7324 = 16.2%

There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds

At a construction job for a house there are 16 painters. Of these painters, 4 of them are painting the

Nikolay [14]

For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:

16 ---------------> 100%

4 -----------------> x

Where "x" represents the% of painters who paint the interior of the house.

$x = \frac {4 * 100} {16}\\x = 25$

Thus, 25% of painters are painting the interior of the house.

25%

victus00 [196]

Answer:

a) $k \approx \frac{\sqrt{3}}{3}$ , b) $\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$

Step-by-step explanation:

a) The constant of proportionality is:

$k = \frac{y}{x}$

$k = \tan \theta$

$k = \tan \frac{\pi}{6}$

$k \approx \frac{\sqrt{3}}{3}$

b) The ordered pair is:

$\left(\frac{\sqrt{3}}{3},\frac{\sqrt{3}}{3}\cdot \frac{\sqrt{3}}{3} \right)$

$\left(\frac{\sqrt{3}}{3}, \frac{1}{3} \right)$
