Answer:

\cot \theta =  \frac{8}{15} \\\\\sec \theta =  \frac{17}{8} \\\\\csc \theta =  \frac{17}{15}

Step-by-step explanation:

\huge \tan \theta =  \frac{15}{8} ...(given) \\  \\  \huge \because \:  \cot \theta =  \frac{1}{ \tan \theta} \\  \\  \huge \therefore \: \cot \theta =  \frac{1}{ \frac{18}{8} } \\  \\  \huge \therefore \:  \cot \theta =  \frac{8}{15}  \\  \\ also \\ \huge  \sec \theta =  \frac{17}{8}  \\

Find the odds for and the odds against the event rolling a fair die and getting a 4 comma a 5 comma or a 2.
skelet666 [1.2K]

The odds in favor are 3:3 which reduces to 1:1

There are 3 ways to get what we want, which is 4, 5 or 2. There are 3 ways to get what we don't want (1,3,or 6). So we list those two values as a ratio like so 3:3, which reduces to 1:1 after you divide both parts by 3.

Here's another example. If we wanted to know the odds in favor of rolling a 5 or 6, then the answer would be 2:4 which reduces to 1:2. This is because there are 2 ways to get what we want (rolling a 5 or 6) and 4 ways to get what we don't want (rolling either 1,2,3, or 4). The number of events we favor is listed first when it comes to "odds in favor" problems.

Fiesta28 [93]

Answer:

360 approx

Step-by-step explanation:

Given data

We want to find the total number of customers that bought gas

Let the total number of customers be x

So

72% of x = 259

let us solve for x

72/100*x= 259

0.72*x=259

x= 259/0.72

x= 359.72

Hence the actual number of customers is 360 approx

nCr=\frac{n!}{r!(n-r)!}
remember than n! means n times all numbers before like
3!=3*2*1, 5!=5*4*3*2*1
9 stations, how many ways are there to chose 6 of them
9C6=\frac{9!}{6!(9-6)!}=
\frac{9!}{6!(3)!}=
