Determine whether each set of ordered pairs shown below is from a geometric sequence or from an arithmetic sequence.

daser333 [38]

Using sequences concepts, it is found that:

The set of ordered pairs {(-3, 7.5) , (-2, 10) , (-1, 12.5)} is an arithmetic sequence with equation a(n) = 15 + 2.5d.

The set of ordered pairs {(1, 150) , (2, 112.5) , (3, 84.375)} is a geometric sequence with $a_n = 150(0.75)^{n-1}$ .

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a(n) = a(0) + nd$

The sequence {(-3, 7.5) , (-2, 10) , (-1, 12.5)} continues with points (0, 15), (1, 17.5), and so on, hence the first term and the common ratio are given, respectively, by:

a(0) = 15, d = 2.5.

Hence the equation is:

a(n) = 15 + 2.5n.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

For the sequence {(1, 150) , (2, 112.5) , (3, 84.375)}, the first term and the common ratio are given, respectively, by:

$a_1 = 150, q = \frac{112.5}{150} = \frac{84.375}{112.5} = 0.75$

Hence the equation is given by:

$a_n = 150(0.75)^{n-1}$

In a survey, 13001300 adults in a certain country were asked how many hours they worked in the previous week. Based on the res

artcher [175]

Answer:

The correct option is (A).

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence interval for mean number of hours worked was,

CI = (39.6 hours, 43.9 hours).

The 95% confidence interval for mean number of working hours, (39.6, 43.9) hours, implies that the true mean number of working hours for the adults of the country lies in this interval with probability 0.95.

So, there is a 95% confidence or chance that the true mean values lies in the interval (39.6, 43.9).

Thus, the correct option is (A).

Which shows how -2.65 can be written as the ratio of two integers

Ksju [112]

-265 / 100 = -2.65

simplifying a little

-53/20 = -2.65

13) If AOBC is a rectangle whose three vertices are A(0,3), (0,0) and B(5,0).

Levart [38]

Answer:

(b) 68

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between them is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Diagonal:

Diagonals are a line between opposite points in a square.

In this question, it is between A(0,3) and B(5,0), and between (0,0) and (5,3). Both these diagonals have the same measure, and are the distance between these points. So

$D = \sqrt{(5-0)^2+(3-0)^2} = \sqrt{5^2 + 3^2} = \sqrt{34}$

Then sum of the squares of its both diagonals is units

Both diagonals measure $\sqrt{34}$ . Sum of squares is:

$(\sqrt{34})^2 + (\sqrt{34})^2 = 34 + 34 = 68$

The correct answer is given by option b.
