A car painting company has determined that the painting time of cars is uniformly distributed between 25 and 105 minutes. What i

Masteriza [31]

Answer:

$P=\frac{5}{16}$

Step-by-step explanation:

For a uniform distribution we have to:

$P (X\leq x) =\frac{x-a}{b-a}$ for x∈ (a, b)

$P (X\leq x) =0}$ for $x\leq a$

$P (X\leq x) =1}$ for $x\geq b$

In this case we have to:

a = 25 min and b = 105 min

We want to find:

$P (40 \leq X \leq 65)$

Then

$P (x_1 \leq X \leq x_2) = P(X \leq x_2) - P(X \leq x_1)$

$P (x_1 \leq X \leq x_2)= \frac{x_2 -x_1}{b-a}$

In this case:

$x_2 = 65\\\\x_1=40$

Therefore:

$P (40 \leq X \leq 65)=\frac{65 -40}{105-25}$

$P (40 \leq X \leq 65)=\frac{25}{80}$

$P (40 \leq X \leq 65)=\frac{5}{16}$

The mean age of 3 women in an office is 35 years old. The mean age of 12 men in an office is 23 years old. What is the mean age

baherus [9]

Answer:

25 years

Step-by-step explanation:

To find the mean you need to find the sum of all numbers and divide by the number of terms there are.

In this case you would need to multiply the mean ages by the number of people used to find the mean:

35 * 3 = 105

23 * 12 = 276

Then add the total ages together:

105 + 276 = 381

Then divide by the number of total people in the office:

12 + 3 = 15

381/15 = 25.4

rounded to 25
