Remark

All triangles have 180o. There are no exceptions to this statement.

Let the unknown angle = x

43 + 79 + x = 180

122 + x = 180 Subtract 122 from both sides

x = 180 - 122

x = 58 <<<< answer

The next problem should be a triangle. Look at the base which is a triangle. Any horizontal plane will cut out a similar triangle to the base.

If we consider the simple random sampling process as an experiment, the sample mean is a. a random variable. b. always zero. c.

marta [7]

The sample mean is an estimate of the population mean.

The sample mean is exactly equal to the population mean

<h3>How to determine the true statement</h3>

When the population mean is known; the value of the population mean can be used as the sample mean.

This is so because:

The sample mean is an estimate of the population mean.

And it is represented as:

$\bar x = \mu$

Hence, the true statement is that the sample mean is exactly equal to the population mean

Item 2

The question is an illustration of a division model.

The boxes will be completed with: 1650, 231, 50 and 7

The expression is represented as:

$\mathbf{1881 \div 33}$

Express 1881 as 1650 + 231.

$\mathbf{1881 \div 33 = (1650 + 231) \div 33}$

Split

$\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}$

Evaluate each division

$\mathbf{1881 \div 33 = 50 + 7}$

$\mathbf{1881 \div 33 = 57}$

The above illustration means that, the boxes will be completed with the following numbers

1650
231
50
7
