Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

P(A|B)=\frac{P(Aand B)}{P(B)}

now, we can plug values

P(A|B)=\frac{0.15}{0.9}

P(A|B)=0.16666

but we have

P(A)=0.5

we can see that both are not equal

P(A|B)\neq P(A)

so, A and B are not independent

so, option-C........Answer

Find the percent of the area under the density curve where x is more than 3. <br>​
Gekata [30.6K]

Answer:

The percent of the area under the density curve where x is more that 3 is 25 %.

Step-by-step explanation:

Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:

A = \frac{1}{2}\cdot (x_{f} - x_{o})\cdot  (y_{f}-y_{o}) (1)

Where:

A - Area, in square units.

x_{f} - x_{o} - Base of the triangle, in units.

y_{f} - y_{o} - Height of the triangle, in units.

The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:

x = \frac{\frac{1}{2}\cdot (5-3)\cdot (0.25) }{\frac{1}{2}\cdot (5-1)\cdot (0.5) }\times 100\,\%

x = 25\,\%

The percent of the area under the density curve where x is more that 3 is 25 %.

Your new job is 25 miles away from your house. If you drive to work at a rate of 50 miles per hour, how long does it take you to
sergeinik [125]

the time taken to get to your work place is 0.5 hour.

The given parameters;

  • distance between  your new job and your house  = 25 miles
  • speed to work, v = 50 mph

The time taken to get to work is obtained by dividing  the distance between your new job and your house, by speed of your motion to work.

Distance = speed x time

Time = \frac{Distance }{speed} \\\\T ime = \frac{25}{50} \\\\Time = 0.5 \ hour

Thus, the time taken to get to your work place is 0.5 hour.
