Answer:
The probability that she sees exactly 4 shooting stars in the next hour is 0.13
Step-by-step explanation:
An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.
where m is the average per hour = 6
Answer:
Angle OAB = 90°
Reason: tangent theorem of a circle
Step-by-step explanation:
The diagram given shows a tangent line of the given circle with center O. The tangent touches the circle at point A.
The diagram also shows the radius of the circle, OA, drawn from the center to the circle to meet at the point of tangency.
Thus, according to the Tangent Theorem of a circle, the point at which the radius drawn from the center meets the point of tangency = 90°. The tangent is perdendicular to the radius drawn to meet at the point of tangency.
Therefore, angle OAB = 90°
Answer:
The location of the point that is 3/4 the distance from is .
Step-by-step explanation:
Let and the endpoints of the segment, we can determine the location of the point that is 3/4 the distance from by the following vector equation:
(1)
If we know that and , the location of is:
The location of the point that is 3/4 the distance from is .
Answer:
add all the sides together and if thats not it you learned something different from me:)
Are you sure it is correct because for each one your just doubling the number. 2+2=4. 4+4=8. 8+8=16. I think its suppose to be 16+16= 32 and so on, but I may be wrong
