Logariths, please help​

Mathematics
1 answer:
Valentin [98]2 years ago
3 0

Answer:

<em>{ - 2 , 8 } </em>

Step-by-step explanation:

log_{4} ( x² - 6x ) = 2

4² = ( x² - 6x )

x² - 6x - 16 = 0

- 6 = - 8 + 2

- 16 = - 8 * 2

( x - 8 )( x + 2 ) = 0 ⇒ x_{1} = - 2 , x_{2} = 8

<em>{ - 2 , 8 }</em>

I need help with question three
miss Akunina [59]

Hey there!

<u>-3 and 1 will both be farther to the right on the number line.</u>

On a number line, the farther right you go, the higher the values get.

Positive numbers are to the right of zero, with negative numbers to the left.

Since both -3 and 1 are larger than -7, they will be farther to the right.

Hope this helps!

A fair coin is continually flipped until heads appears for the 10th time. Let X denote the number of tails that occur. Compute t
Ierofanga [76]

Answer:

The probability mass function is expressed as:

P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]

Step-by-step explanation:

This is not a binomial distribution. It is actually a negative binomial distribution. The probability mass function is expressed below:

P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]

where:

x = number of failures

r-1 = number of successes (10 in this scenario)

p = probability of a success

nCr = n!/[r!(n-r)!]

The main formula difference in the positive binomial versus negative binomial is this: With respect to the negative binomial, it is obviously  known that the last event will be: when we reach our 10th "head", we stop .

Thus, the last flip will ALWAYS be a "head".
