The product –2 • (–5) is shown on the number line. Use the drop-down menus to explain how the model on the number line could be

egoroff_w [7]

The procedure for representing the product $-2\cdot (-5)$ is described as following:

1) Draw the distance of the first negative number.

2) Extend the distance by the magnitude of the second negative number.

3) Draw the distance of the reflection of the result found in 2).

In the number line negative numbers represent leftward distances. The product of a negative number and a positive number is equal to the distance of the negative one by the number of times such distance is repeated. In addition, we know by algebra that the product of two negative numbers equals a positive number, so we know that distance becomes rightwards due to reflection on the former line segment.

The procedure is described as following:

1) Draw the distance of the first negative number.

2) Extend the distance by the magnitude of the second negative number.

3) Draw the distance of the reflection of the result found in 2).

For a geometric series represented by ++2+3,..., wherein is the first term and the common ratio, calculate the sum of the first

labwork [276]

Answer:

Sum of the first 3 terms is 9245

See explanation below

Step-by-step explanation:

The question is not clear. From the question we can tell we are to determine the sum of the first 3 terms of a geometric series. I would show you how to calculate sum of n terms given first term and common ratio.

Let's consider the question below.

Given that the first term is 15 and the common ratio is 6, find the first 3 terms

Solution:

Sum of geometric series has two formulas: one is for common ratio(r) > 1 and the other is for common ratio (r) < 1

Since the r in the question is > 1. We would apply the formular that applies to it.

Sum of the first 3 terms is 9245

Answer:

(0.4062, 0.5098)

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence interval $1-\alpha$ , we have the following confidence interval of proportions.
