Step-by-step explanation:
Calculate the probability that your job will be ready before 10.01 am
Here, the parameter of an Exponential is E(X)=12
Now, to calculate the third job probability, it follows Poisson Distribution with parameter 1/λ
Therefore, E(Y) =1/12
Here, The third job will be ready for 10:01 AM, then E(Y)=61/12
Therefore, the required probability is
=1- POISSON(3,5,true)
=1-0.1246
=0.8753
Answer:
Step-by-step explanation:
Given:
°
From the triangle, using the theorem that center angle by an arc is twice the angle it subtend at the circumference.
Also, the diameter of the circle is BD. As per the theorem that says that angle subtended by the diameter at the circumference is always 90°,
From the Δ BCD, which is a right angled triangle,
Now, using the theorem that angle between the tangent and a chord is equal to the angle subtended by the same chord at the circumference.
Here, chords CD and BC subtend angles 40 and 50 at the circumference as shown in the diagram by angles and EF is a tangent to the circle at point C.
Therefore,
Again, using the same theorem as above,
Hence, all the angles are as follows:
Answer:
The correct option is four.
Step-by-step explanation:
The associative property implies that the values are added however we want, i.e. the numbers can be grouped in any way and the answer would still be the same.
The associative property of addition is:
The expression provided is:
(13 + 15 + 20) + (20 + 47 + 18)
The answer provided by four students are:
Jeremy : (20 + 13 + 15) + (20 + 47 + 18)
Layla : (20 + 47 + 18) + (13 + 15 + 20)
Keith : (13 + 20) + (20 + 47 + 18) + 15
Melinda : (13 + 15 + 20 + 20) + (47 + 18)
So, all the four students correctly applied only the associative property to rewrite the expression.
The correct option is four.
