Answer:

We conclude that is the binomial distribution.

Step-by-step explanation:

We know that the binomial distribution describes the probability of k successes in n draws with replacement.

We know that:  Spinning an  American roulette wheel 45 times and recording the number of times the ball lands on green.

So with each new turn, we have the same opportunity for the ball to be on the green.

We conclude that is the binomial distribution.

What is the 7th term of the geometric sequence where a1 = -625 and a2 = 125
kykrilka [37]
Since the sequence is geometric, there is some constant r such that the sequence is recursively given by

a_n=ra_{n-1}

By this definition, you can recursively substitute into the right hand side the definition for a_{n-1},a_{n-2},\ldots to find an explicit formula for the nth term.

a_n=ra_{n-1}=r^2a_{n-2}=r^3a_{n-3}=\cdots=r^{n-1}a_1=-625r^{n-1}

You know the second term, which means you can find r:

a_2=-625r^{2-1}\implies125=-625r\implies r=-\dfrac15

So, the 7th term of the sequence is

a_7=-625\left(-\dfrac15\right)^{7-1}=-\dfrac1{25}

Answer:

85

Step-by-step explanation:

because A is half of that and if you divided 170 by 2 you would get 85, I think that's how you do it.

Help me please i don’t get it
Fofino [41]

Answer:

4

Step-by-step explanation:

Both triangles are the same shape, just to different scales. In order to find out the length of side AB in triangle ABC, you have to find out the length of side PQ in triangle PQR and how much bigger than side AB is.

You can tell that sides AC and PR are similar, and 30/5 is 6. You see also that sides BC and QR are similar, and 42/7 is also 6. We have now discovered that triangle PQR is 6 times bigger than triangle ABC.

So now, to find the length of the missing side, we have to shrink side PQ by 6.  24/6 is 4. Therefore, the length of side AB is 4.
