The number of possibilities for the first one is 50 choose 5, and the number of possibilities for the second one is 60 choose 6. Since 50 choose 5 is 2118760 and 60 choose 6 is 50063860. There are less possible outcomes for state "A" and therefore you have a higher chance of winning.
Answer:
x=20
Step-by-step explanation:
sin¢=cos90-¢
therefore; 3x-15+x+25=90
4x+10=90
4x=90-10=80
x=20
Answer:
A 20
Step-by-step explanation:
Given
Phone Battery Life (hours)
A 20
B 25
C 10
D 18
8.45% of the battery life of each mobile phone is used in a day by a typical user
Calculating Hours of battery life in a day for each mobile
A 20
Battery life for A = 
hours
B 25
Battery life for B = 
hours
C 10
Battery life for C = 
hours
D 18
Battery life for D = 
hours
Therefor Mobile phone A 20 uses a total of 1.69 hours of battery life in a day
To solve this problem, we have to figure out a rule for the function. We are told that it is a two-step rule, so it is most likely the input multiplied by a coefficient plus a constant. Let’s let the input be represented by the variable x and the output be represented by the variable y. Using our knowledge, we can see that the outputs are close to triple the input, so we set up the preliminary equation:
y = 3x + b,
where b is a constant. If we want to solve for b, we must plug in one of our input/output pairs. If we plug in (5,16), we get the following:
16 = 3(5) + b
16 = 15 + b
1 = b
Then, we should substitute in this value into our equation and check our work.
y = 3x + 1
If we plug in the other points, this equation yields a true statement, so we know it is correct.
Hope this helps!
