Answer:
0.01024
Step-by-step explanation:
Assume marking was done at random : Hence, each of the 5 time slots have equal Chamves of being marked ;
Number of time slots, n = 5
Required to mark, number of preferred timeslot x = 2
P(x) = 2 /5 = 0.4
Probability of 0.4 that an interviewee gets one of his preferred timeslot.
Probability that each of the 5 interviewees gets one of their preferred time slots :
Using the multiplication rule of independence :
0.4 * 0.4 * 0.4 * 0.4 * 0.4 = 0.4^5 = 0.01024
0.01024 * 100% = 1.024%
Answer:
option D
Step-by-step explanation:
diameter of two small circle i.e 14cm
radius of two small circle =7cm
area of the small circle =πr²
area of the small circle=22/7 x7²
area of the small circle=154cm²
- Radius of bigger circle =14cm
- Area of bigger circle=πr²
Area of bigger circle=22/7×14²
Area of bigger circle=616cm²
Area of shaded region =area of bigger circle -area of small circle +area of small circle
area of shaded region =616-154+154
area of shaded region=308cm²
i.e approximately 282.74cm²
<h3>
Answer: 4/9</h3>
========================================================
Explanation:
The outcomes of the die are {1,2,3,4,5,6} which is the sample space.
The values less than 5 are {1,2,3,4}
There are 4 values we want out of 6 total, so 4/6 = 2/3 is the probability of rolling something less than 5 on a single die.
The probability of getting two such values in a row is (2/3)*(2/3) = 4/9
Each die roll is independent of any other.
The height of the flag pole which is described as in the task content is; 8.2m.
<h3>What is the height of the flagpole as described from the top of the 6m house?</h3>
The horizontal distance between the 6m house and the flagpole in discuss can be evaluated by means of the angle of depression and trigonometric identity, tan as follows;
tan 22° = 6/x
x = 6/tan 22 = 14.9m.
Consequently, the horizontal distance from the top of the house to the top of the flagpole is therefore;
tan 9° = y/14.9
y = 14.9 tan 9° = 2.2m
Ultimately, the height of the flagpole is; 6+2.2 = 8.2m.
