A piece-wise function combines more than one functions of different input values.

<em>The value of f(-1) is -3</em>

From the graph, we have the following observations

  • <em>When x = -1, y = -3</em>
  • <em>When x = -1, y = -4</em>

Notice that there is a closed circle at the point where x = -1 and y = -3.

This means that y = -3 is inclusive of the values of y on that particular function

However, there is an open circle at the point where x = -1 and y = -3.

This means that y = -4 is exclusive of the values of y on that particular function

The correct corresponding value of y is when y is inclusive.

Hence, the value of f(-1) is -3

See attachment for the graph of the piece-wise functions

Answer for x.<br><br> 1. 3x - 10 = -21<br><br> 2. -22 - 4x = 12
ra1l [238]

Answer:

3x - 10 = -21

add 10 on both side

3x-10+10=-21+10

3x=-11

divide both side by 3

3x/3=-11/3

x=-11/3

Step-by-step explanation:

2. -22 - 4x = 12

add 22 on both side

-22+22-4x=12+22

-4x=36

divide both side by -4

-4x/-4=36/-4

Hypothesis testing on samples with fewer than 30 participants can be carried out by using the t-value for the corresponding leve
Eva8 [605]

Answer: true

Step-by-step explanation:

Z-tests are statistical calculations that can be used to compare the population mean to a sample mean The z-score is used to tellsbhow far in standard deviations a data point is from the mean of the data set. z-test compares a sample to a defined population and is typically used for dealing with problems relating to large samples (n > 30). Z-tests can also be used to test a hypothesis. Z-test is most useful when the standard deviation is known.

Like z-tests, t-tests are used to test a hypothesis, but a t-test asks whether a difference between the means of two groups is not likely to have occurred because of random chance. Usually, t-tests are used when dealing with problems with a small sample size (n < 30).

Both tests (z-tests and t-tests) are used in data with normal distribution (a sample data or population data that is evenly distributed around the mean).
