Answer:

x = $6\sqrt{3}$ i

Step-by-step explanation:

We can write the following equation according to Euclidian Theorem to find the value of x:

$x^{2}$ = 12*9 multiply 9 and 12

$x^{2}$ = 108 find the root of both sides

x = $6\sqrt{3}$ is the value of x

Answer:

The probability mass function (pmf) of X is:

$P(X=k)={{k+r-1}\choose k}\cdot (1-p)^{k}\cdot p^{r};\ k=1,2,3,...$

Step-by-step explanation:

The random variable X is said to be a Negative Binomial random variable.

The random variable X is defined as the number of failures in a series independent and identical Bernoulli trials, before a specific number of success takes place.

For example, consider rolling a 5 on a six-sided die as the success and any other number as failure. Then the number of rolls before 5 occurs three times in a row can be defined as a negative binomial experiment.

The probability mass function of a negative binomial random variable X is:

$P(X=k)={{k+r-1}\choose k}\cdot (1-p)^{k}\cdot p^{r};\ k=1,2,3,...$

Here,

k = number of successes

r = number of failures

p = probability of success

Rick is buying $115 tennis racket from a sporting good store. If the racket is on sale for 35% off in sales tax is 8% how much w

notka56 [123]

Answer:

$80.73

Step-by-step explanation:

First, find 35% of 115.

35% as a decimal is 0.35 (35/100)

0.35 x 115 = 40.25

Now, subtract 40.25 from 115.

115 - 40.25 = 74.75

Now, to find the sales tax, find 8% of 74.75.

8% as a decimal is 0.08 (8/100)

0.08 x 74.75 = 5.98

Now, subtract add 5.98 to 74.75

5.98 + 74.75 = 80.73

100%-> 2900
1%-> 2900/100
=29
29-> 1%
1595->?

1595/29=55

29->1%
1595->1 x 55
=55%

So, 55% is your answer !!
Hope this helps :)
