Answer:

nth term, $T_n=1(2)^n^-^1$

10th term, $T_1_0=512$

Step-by-step explanation:

From the question;

We are given the first term, $a_1=1$
The common ratio, r = 2

We are required to write the formula of getting nth term and find the 10th term of the sequence;

We need to know that for nth term in a geometric sequence, we use the formula;

$T_n=a_1r^n^-^1$

Therefore, in this case;

nth term will be given by;

$T_n=1(2)^n^-^1$ , where n is the term in the sequence;

Therefore;

To get the 10th term of the sequence;

$T_1_0=1(2)^1^0^-^1$

$T_1_0=1(2)^9$

$T_1_0=512$

Therefore, the tenth term of the sequence is 512

It is impossible to get 6 jacks when selecting cards from a shuffled deck. Express the indicated degree of likelihood as a proba

Vinil7 [7]

Answer:

Probability = 0

Step-by-step explanation:

If something happening is impossible, it's probability of occurring is also 0.

A deck of cards only contains 4 jacks.

Thus you can never get 6 jacks out of the deck without replacing the selected card each time.

Since we are not replacing the cards once we pick them, this event is impossible to occur.

Suppose I claim that the average monthly income of all students at college is at least $2000. Express H0 and H1 using mathematic

pishuonlain [190]

Answer:

For this case we want to test if the the average monthly income of all students at college is at least $2000. Since the alternative hypothesis can't have an equal sign thne the correct system of hypothesis for this case are:

Null hypothesis (H0): $\mu \geq 2000$

Alternative hypothesis (H1): $\mu$

And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 200 or no

Step-by-step explanation:

Null hypothesis (H0): $\mu \geq 2000$

Alternative hypothesis (H1): $\mu$

And in order to test this hypothesis we can use a one sample t or z test in order to verify if the true mean is at least 2000 or no

The Opera House sells an average of 1,700 tickets per night when the price of each ticket is $25. An employee of the Opera House

irakobra [83]

So here's the solution to the problem:

Calculate the average sell:

1,700 * $25 = $42,500 (revenue)

And if the Opera House wants to increase their revenue:

The price of a ticket will be:

$25 - x (where x is the number of 1-dollar decreases)

The number of tickets in total:

1,700 + 200x

Therefore the equation is:

(1,700 +200x) * ( 25 - x ) = 55,000

We can also solve this equation, but the solutions are not whole numbers.

x 1 = 5.89 and x 2 =10.6

For x = 6 (6 times 1 - dollar decreases):

( 1,700 + 200 * 6 ) * ( 25 - 6 ) = ( 1,700 + 1,200 ) * 18

=2,900 *19 = 55,100 (we will yield the revenue over $55,000)
