Answer:
0.6127 = 61.27% probability of selling no more than 6 properties in one week.
Step-by-step explanation:
For each property, there are only two possible outcomes. Either it is sold, or it is not. The probability of a property being sold is independent of any other property. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
12 properties
This means that 
She feels that there is a 50% chance of selling any one property during a week.
This means that 
Compute the probability of selling no more than 6 properties in one week.
This is:
In which
0.6127 = 61.27% probability of selling no more than 6 properties in one week.
Answers:
x = 51
y = 39
===========================================================
Explanation:
The angles 39 and x form a right angle, aka 90 degree angle. This is shown by the small square angle marker.
One equation to solve is x+39 = 90. Doing so leads to x = 51 after subtracting 39 from both sides.
Similarly, another equation to solve is x+y = 90. Plug in x = 51 and isolate y
x+y = 90
51+y = 90
y = 90-51
y = 39
Answer:
$73
Step-by-step explanation:
Multiply 7 and 7 to get 49. Next, multiply 6 and 4 to get 24. The museum is free for the 3 children so you do not have to do anything. Add 49 and 24 to get 73, which is the price for the Baker Family.
Answer:
Step-by-step explanation:
hello :
Y=x+8
Y=-4x-12
-4x-12 = x+8
-5x = 20
x = -4
but : y=x+8
so : y=-4+8 = 4
Answer:
Step-by-step explanation:
-4 < x ≤ 1
