Problem 1 a jar contains blue, red and green balls. the null-hypothesis h0 is that there is 25% percent of red balls. (1) a samp

le of 36 ball have been randomly pull out of jar. it contained 16 red balls. what is the probability of that happening? do you still believe that jar contains 25% red balls? answer:_____________________________________________________ (2) we create a statistic which we will use to test the h0 . the statistic is simply a number of red balls in the sample of 36 balls. we make a decision that we will reject the null-hypothesis if sample contains more than 15 red balls. what is the probability of that happening assuming that null-hypothesis is true?

(1) the probability of that happening is .4444.. so on. the jar isnt 25% red balls because 25% of 36 is only 9 and he pulled out 16 red balls. 

I dont know number two sorry.

Verify identity: <br><br> (sec(x)-csc(x))/(sec(x)+csc(x))=(tan(x)-1)/(tan(x)+1)
Nikitich [7]
So hmmm let's do the left-hand-side first

\bf \cfrac{sec(x)-csc(x)}{sec(x)+csc(x)}\implies \cfrac{\frac{1}{cos(x)}-\frac{1}{sin(x)}}{\frac{1}{cos(x)}+\frac{1}{sin(x)}}\implies &#10;\cfrac{\frac{sin(x)-cos(x)}{cos(x)sin(x)}}{\frac{sin(x)+cos(x)}{cos(x)sin(x)}}&#10;\\\\\\&#10;\cfrac{sin(x)-cos(x)}{cos(x)sin(x)}\cdot \cfrac{cos(x)sin(x)}{sin(x)+cos(x)}\implies \boxed{\cfrac{sin(x)-cos(x)}{sin(x)+cos(x)}}

now, let's do the right-hand-side then  

\bf \cfrac{tan(x)-1}{tan(x)+1}\implies \cfrac{\frac{sin(x)}{cos(x)}-1}{\frac{sin(x)}{cos(x)}+1}\implies \cfrac{\frac{sin(x)-cos(x)}{cos(x)}}{\frac{sin(x)+cos(x)}{cos(x)}}&#10;\\\\\\&#10;\cfrac{sin(x)-cos(x)}{cos(x)}\cdot \cfrac{cos(x)}{sin(x)+cos(x)}\implies \boxed{\cfrac{sin(x)-cos(x)}{sin(x)+cos(x)}}

A) show that $n(2n + 1)(7n + 1)$ is divisible by 6 for all integers $n$.
goldenfox [79]
Hi,

A)
\dfrac{n(2n+1)(7n+1)}{6} \\&#10;&#10;= \dfrac{14n^3+9n^2+n}{6} \\&#10;&#10;= \dfrac{12n^3+6n^2}{6} + \dfrac{2n^3+3n^2+n}{6} \\&#10;&#10;=2n^3+n^2+ \dfrac{n(2n^2+3n+1)}{6} \\&#10;&#10;= 2n^3+n^2+ \dfrac{n(n+1)(2n+1)}{6} \\&#10;&#10;= 2n^3+n^2+ 1^2+2^2+3^2+...+n^2\ is\ an\ integer.&#10;

B)
Only if n=4*k or n=4*k+1 , k beeing an integer.

Two numbers have these properties both numbers are greater than 6 their highst common factor is 6 there lowest common factor is
levacccp [35]

Answer:

The two numbers are 12 and 30

Step-by-step explanation:

Both numbers are greater than 6

Their HCF is 6 and their LCM is 60.

A possible guess of the two numbers will be 6 and 60, which were given in the question, because they satisfy this HCF and LCM values, but the question also tells us that both numbers are greater than 6.

Now, we will obtain the answer using what we have.

Since the HCF is 6, that means that both numbers that we seek are a multiple of 6.

Next, the LCM is 60. We can divide the LCM by the HCF, that is \frac{60}{6} = 10

This tells us that the two numbers are within 6 and (6 × 10).

Next we write out the factors of the 10 that we got by dividing the LCM by the HCF.

Factors of 10 are: 1, 2, 5 and 10.

We multiply each of this by 6 (which is the HCF, recall that we had said that HCF means that the numbers are a multiple of 6), to get the numbers; <em>6, 12, 30 and 60</em>

Since 6 and 60 are already the given LCM and HCF, the two numbers that we seek are 12 and 30.
