9 0

Answer:

280

Step-by-step explanation:

We know that there are at least 8 regular subscribers and there are at least 9 premium subscribers. And we know it's in that ratio. So the best way to start this is to divide 595 by 8+9 to get the single unit amount of both subscribers:

595/17 = 35

So one unit of anything is at least 35. Now, since we're looking for regular subscribers, we'll multiply this value by 8:

35*8 = 280

So 280 is our answer!

<h3>Answer:</h3>

$\frac{1}{6}$

<h3>Step-by-step explanation:</h3>

There are 6 possible options: $\text{1, 2, 3, 4, 5, 6}$

There is 1 option out of those 6 that we are finding: $\text{3}$

Therefore, the probability is $\frac{1}{6}$ .

Simora [160]

Step-by-step explanation:

f(n) = - 29 - f( n - 1 )

f(1) = - 16

Now

f(2) = - 29 - f ( 2 - 1 )

= - 29 - f ( 1)

= -29 - ( - 16)

= - 29 + 16

= - 13

You order seventeen burritos to go from a Mexican restaurant, seven with hot peppers and ten without. However, the restaurant fo

Kisachek [45]

Answer:

$P=0.369$

Step-by-step explanation:

In this binomial probability case, the success is to pick a burrito with hot peppers, there are 7 out of 17, the probability is p=7/17=0.4118. The formula is

$P=_nC_kp^k(1-p)^{n-k}$

Where n is the number of burritos taken at random, k is the number of success (burrito with hot peppers), p is the probability of success. $_nC_k$ denotes the number of combinations and its formula is:

$_nC_k=\frac{n!}{k!(n-k)!}$

At least two burritos have hot peppers means having two or three burritos, these two cases are calculated and sum to get the probability of at least two burritos that have hot peppers.

$P=_nC_kp^k(1-p)^{n-k}=\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}$
