Answer:

$- 2\frac{1}{2}$ inches

Step-by-step explanation:

The water level at Lake Penny changed $- 1\frac{1}{10} = - 1.1$ inches

Again, in the next year, it is predicted to change another $- 1\frac{2}{5} = - 1.4$ inches

Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches = $- 2\frac{1}{2}$ inches. (Answer)

Answer: option 1

Step-by-step explanation: By constructing a 99% confidence interval for population proportion, it implies that the principal is 99% sure that the confidence interval will contain the population proportion.

When we construct confidence interval, we do so to show that the population parameter that we are looking for is present in the interval at a specified confidence level.

Z varies directly with q. when z=2,q=1 . find a formula connecting z and q z=???

Lostsunrise [7]

Answer:

$z = \frac{q}{2}$

Step-by-step explanation:

$z \infty q$

$z = kq$

$z = 2 \: and \: q = 1$

$2 = k1$

$k = \frac{2}{1}$

$z = \frac{1}{2} q$

$z = \frac{q}{2}$

Answer:

a) The table of values represents the ordered pairs formed by the elements of the sequence ( $a_{i}$ ) (range) and their respective indexes ( $i$ ) (domain):

$i$ $a_{i}$

1 6

2 11

3 16

4 21

5 26

b) The algebraic expression for the general term of the sequence is $a(i) = 6 + 5\cdot (i - 1)$ .

c) The 25th term in the sequence is 126.

Step-by-step explanation:

a) Make a table of values for the sequence 6, 11, 16, 21, 26, ...

The table of values represents the ordered pairs formed by the elements of the sequence ( $a_{i}$ ) (range) and their respective indexes ( $i$ ) (domain):

$i$ $a_{i}$

1 6

2 11

3 16

4 21

5 26

b) Based on the table of values, we notice a constant difference between two consecutive elements of the sequence, a characteristic of arithmetic series, whose form is:

$a(i) = a_{1} + r\cdot (i - 1)$ (1)
