Answer:

n=-5

Step-by-step explanation:

You must multiply x^{-8}*x^{3}. The laws of exponents state that when multiplying exponents of the same base, you can just add the exponents and raise the base to the sum of the exponents. So, x^{-8}*x^{3}=x^{(-8+3)}=x^{-5}.  Since our end product is x^{-5}, n is equal to -5.

After simplifying, how many terms does the expression 4y-6+y2-9 contain?​
Alex73 [517]

Answer:

There are three terms in the simplified expression.

Step-by-step explanation:

We have to simplify the expression and have to count the number of terms that the expression has.

The expression is 4y - 6 + y² - 9

= 4y + y² - 6 - 9

= y² + 4y - 15

Therefore, there are three terms in the simplified expression, one for y² term, another is y term and the constant term. (Answer)

You flip 3 coins. Is the probability of obtaining 2 heads and 1 tail in any order the same as the probability of obtaining a hea
konstantin123 [22]

Answer:

the probability of obtaining 2 heads and 1 tail in any order is higher than the probability of obtaining a head, than a head then a tail

Step-by-step explanation:

since the probability (p) of obtaining 2 head and 1 tail in any order is

P1 = p of obtaining ( H , H ,T) + p of obtaining ( H , T ,H ) + p of obtaining ( T , H ,H ) = 3*p of obtaining ( H , T ,H)

assuming a fair coin then p heads = p tails = 0.5

thus since each flip is independent from the others

p( H , H ,T)=p( H , T ,H )= p( T , H ,H )= P=0.5*0.5*0.5= 1/8

thus P1 =3*1/8=3/8

while the probability of obtaining a head, than a head then a tail is

P2= p of obtaining ( H , T ,H)= 1/8

then P1=3/8 >P2=1(8

therefore the probability of obtaining 2 heads and 1 tail in any order is higher than the probability of obtaining a head, than a head then a tail

Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?​
Cerrena [4.2K]

2 occurred 3times

\\ \sf\longmapsto S=6\times 3=18

\\ \sf\longmapsto |S|=18

Now

\\ \sf\longmapsto E=No\:of\:times\: 2\:occured

\\ \sf\longmapsto |E|=3

we know

\boxed{\sf P(E)=\dfrac{|E|}{|S|}}

\\ \sf\longmapsto P(E)=\dfrac{3}{18}

\\ \sf\longmapsto P(E)=\dfrac{1}{6}
