Since an equilateral triangle has 3 equal length sides, and in this case the total of these 3 sides is 24cm, the length of one side is 24/3 = 8cm
Since in 1990 there are 28%, we need to figure out when it gets to 31%. In addition, since it increases by 0.6% every year, we can say that 0.6x+28 (since 28 is the base value) is the percentage of babies born in wedlock every year. Therefore, to get 0.6x+28=31, we subtract 28 from both sides to get 0.6x=3
Dividing both sides by 0.6, we get x=5=the amount of years it takes to get 31% of babies born in wedlock. Since 1990 is the base value (we start from there!), we add 5 to that to get 1990+5=1995 as the yar
Answer:
? = -36
Step-by-step explanation:
When you raise an exponent to an exponent, the resulting power is a product of the two exponents.
For this problem, you can solve for the missing value by writing:

Divide both sides by 1/3 to isolate the missing value.

Solve for ?.

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
![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)
Here x can take values x = 0 , 1 , 2 , 3 , ... , 7
