A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin

ed that the employee is equally likely to arrive at any time between 8:00 a.m. and 8:30 a.m. Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m. Round your answer to four decimal places, if necessary.

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

P(c \leq X \leq d) = \frac{d - c}{b - a}

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am  = 30, so a = 0, b = 30

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Answer:

5b+1c=3b+5c

Step-by-step explanation:

Let's use the variable c for the circles and b for the boxes.

The weights are the same on both sides, so count the boxes and circles on each side.

There are 5 boxes and 1 circle on the left side. The left side of the equation says 5b+1c.

There are 3 boxes and 5 circles on the right side. The right side of the equation says 3b+5c.

And since the 2 sides are equal, you split the 2 sides of the equation with =.

5b+1c=3b+5c

Differentiate. F(x) = (x3 - 3)2/3 2x f'(x) - 3 8 O f'(x) = 3 8 2x2 f'(x) 3 VX3 -8 f(x) 3 V3-8​
oee [108]

Answer:

f'(x) =   \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3}  - 8) } }

Step-by-step explanation:

f(x) = ( {x}^{3}  - 8)^{ \frac{2}{3} }  \\  \\ f'(x) =  \frac{2}{3} ( {x}^{3}  - 8)^{ \frac{2}{3} - 1 } (3 {x}^{2}  - 0) \\  \\ f'(x) =  \frac{2}{3} ( {x}^{3}  - 8)^{ \frac{2 - 3}{3}  }  \times 3 {x}^{2} \\  \\ f'(x) =  2{x}^{2}( {x}^{3}  - 8)^{ \frac{ - 1}{3}  } \\  \\ f'(x) =   \frac{2{x}^{2}}{( {x}^{3}  - 8)^{ \frac{ 1}{3}  } } \\  \\ \huge \red{ \boxed{ f'(x) =   \frac{2{x}^{2}}{ \sqrt[3]{( {x}^{3}  - 8) } } }}
