Basing on the table, in each row, if you divide the cost by the number of people, all of them will yield 55. This means that each person, whether as an individual or in a group, must pay $55 in order to rent a fishing charter boat.

An online article about an opinion poll says that "41% of Americans own a gun." The poll is based on online survey interviews wi
sergejj [24]

Answer:

See below

Step-by-step explanation:

A) The population of the poll is the United States Population EXCLUDING New England States. In other words, the population is all USA population except the New England population. Remember that population is all the set of individuals from where you extract your sample. The sample are those 2,700 adults interviewed.

B) The sampling used is, as said in the statement, a randome sampling.

C) Yes! There could be a bias because of the exclusion of New England States if the people who lives there tends to have more guns than the average american population. This could be, for example, due to that those states have the least gun owning in America or, contrary, if they have the highest. If Rode Island is the most violent state and has the highest gun owning rate, the results could be biased.  However, we can't confirm it without seeing the data, but there is possible.

The system shown has the unique solution (2, y, z). Solve the system and select the values that complete the solution. y = 0 y =
madreJ [45]
So we are given a system:
3x-2y+3z=0\\
-3x - 5y - 5z= -21
Substitute x = 2 we get the system:
-2y+3z=-6\\
- 5y - 5z= -15
Multiply the first equation by -5 and the second by 2 we get the system:
10y-15z=30\\
- 10y - 10z= -30
Adding the two equations we get :
-25z=0\text{ then}z=0.
We find the value of y by using any of the other equations like this:
-2y=-6\\y=3.
Final solution:
z=0,y=3

For each of the following, decide if the given series is a geometric series. A. 5+25x+125x2+625x3+3125x4+⋯ : Is this a geometric
Westkost [7]

Answer:

A. Yes.

B. Yes.

C. No.

Step-by-step explanation:

A. Yes. The sum of the series, 5 + 25x + 125x^{2} + 625x^{3} + 3125x^{4} + ........... is the sum of a geometric series.

The first term of the series a_n = 5.

The common ration or the ratio between successive terms (r) = \frac{25x}{5} = 5x (Answer)

B. Yes. The sum of the series, 5x^{7} + 5x^{8} + 5x^{9} + 5x^{10} + ............ is also the sum of a geometric series.

The first term of the series a_n = 5x^{7}.

The common ration or the ratio between successive terms (r) = \frac{5x^{8} }{5x^{7} } = x (Answer)

C. No. The sum of the series, 5 + 5x + 5x^{2} + 5x^{4} + 5x^{8} + ........... is not the sum of a geometric series.

The first term of the series a_n = 5.
