Choose the best answer that represents the property used to rewrite the expression.

Mathematics
1 answer:
balandron [24]4 years ago
7 0

Answer:

The Quotient Property.

Step-by-step explanation:

Since all three logarithms have the same base (base-5), and you are subtracting 6 and 3, to solve this all you need to do is 6 / 3 because of the Quotient Property.

You aren't multiplying anything, so you wouldn't use the Product Property.

You are not messing around with powers, so you wouldn't use the Power Property.

And you aren't using addition or multiplication, so you wouldn't use the Commutative Property.

Hope this helps!

Which one is correct ?
olga55 [171]

Give the two exterior angles of 133 and 142, we can deduce that the interior angles are 47 and 38, respectively. In fact, if i and e are the interior and exterior angles, respectively, we have

i=180-e

Now, the interior angles of a triangle sum up to 180 degrees. Since we already have angles of 47 and 38 degrees, the missing angle is

180-47-38=95

Which implies

n=180-95=85

Aron flips a penny 9 times. Which expression represents the probability of getting exactly 3 heads?
DedPeter [7]

Answer:

9C3*(0.5)^3(0.5)^6

Step-by-step explanation:

The binomial probability formula shown has variables which represents:

n is the total number of trials (here, we flip penny 9 times, hence n = 9)

k is the number we want to find (here, we want the probability of 3 heads, so k = 3)

p is the probability of success (here, success means getting heads. So, in a coin flip the probability of heads is always 1/2, so p = 1/2)

<em>Putting all the info into the equation and using formula for nCk, we get:</em>

P(k successes)=nCk*p^{k}(1-p)^{n-k}\\P(3Heads)=9C3*(0.5)^3(1-0.5)^{9-3}\\P(3Heads)=9C3*(0.5)^3(0.5)^6

The first expression shown in the answer choices is right.
