Answer:



Step-by-step explanation:
In this case we can calculate the probability using the binomial probability formula

Where p is the probability of obtaining a "favorable outcome " x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.
(a) exactly five
This is:

So:


(b) at least six
This is: 


(c) less than four
This is: 


This is an arithmetic the common difference is 11.
so 19-11 is 8
8-11 is 3 etc...
Answer:
18 is 72% of 25 which is also known as 28% less of 25
Step-by-step explanation:
18/25=.72
1-.72=.28
.28=28%
Answer:
The value of b is -42
Step-by-step explanation:
Parallel equations have identical or equal slopes. Given the form of the equation; y=5x+b and the point it passes through (8,-2) we determine the unknown value b by substituting x with 8 and y with -2. We solve the equation; -2 =5(8)+b to obtain b = -42
Answer:
5
Step-by-step explanation:
Slope equation is (y2-y1)/(x2-x1)
(-1-4)/(2-3)
-5/-1
