Answer:
<h2>The answer is 0.008789.</h2>
Step-by-step explanation:
The probability of getting a head or tail in a toss is 
.
It is given that in the 6th toss, the outcome should be head.
Rather than the 6th toss, there are 9 tosses. From these 9 tosses 1 toss can be selected in 9 ways.
Hence, the probability is 
= 0.008789.
Answer:
Step-by-step explanation:
This is an geometric series.
Common ratio = second number÷ first number
To get the next number, 256 should be divide by (-4)
The three numbers are : -64 , 16 , -4
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
(f○g)(x)=f(g(x))
(f○g)(x)=6(4x+1)
(f○g)(x)=24x+6
Answer:
x= -3+√2 or x= -3-√2 ( answer : A and B )
Step-by-step explanation:
hello :
x²+6x+9 = (x+3)².....identity
x²+6x+9 =2 means : (x+3)²=2
so : (x+3 = √2) or (x+3 = - √2)
so two solutions :
x= -3+√2 or x= -3-√2
