The answer to this is b- 8
Answer:
The probability mass function is
![F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }](https://tex.z-dn.net/?f=F%28x%29%20%3D%20%20%5B%20%5Cleft%20%5C%208%20%7D%20%5Catop%20%7Bx%7D%7D%20%5Cright.%20%5D%20%2A%20p%5Ex%20%20%2A%20%20q%5E%7Bn%20-%20x%20%7D)
Step-by-step explanation:
From the question we are told that
The maximum transmission time is 
Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p
Generally the probability mass function is mathematically represented as
Here x can take values x = 0 , 1 , 2 , 3 , ... , 7
Original shape will contract when scale factor is less than 1 , expand when scale factor is greater than 1 and it doesn't change when scale factor is 1
A scale factor is a number that can be used to change the size of any geometrical figure or shape in relation to its original size. It is the ratio of the sizes of the original and dilated figures.
It is denoted by "k"
The magnitude of the scale factor is taken into account, and it cannot be zero. The scale factor has the ability to either increase or decrease the size of an object.
The basic formula for calculating the scale factor of a dilated figure is as follows:
Scale = dimension of preimage / dimension of image
According to the question,
(a) If scale factor is less than 1 , k < 1 then the original shape will contract means It's size will decrease
(b) If scale factor is greater than 1 , then image will enlarge and it would expand
(c) If scale factor is equal to 1 , then No change in shape nor in size

Answer:
x = - 3
Step-by-step explanation:
Given
7 + x - 3 = x - 5 - 3x ( simplify both sides )
4 + x = - 2x - 5 ( add 2x to both sides )
4 + 3x = - 5 ( subtract 4 from both sides )
3x = - 9 ( divide both sides by 3 )
x = - 3
