True, because all angles on a straight line add up to 180 deg
Given:
The cost to install x number of central air conditioning units for a company is given by the function

To find:
The cost to install 45 air conditioners.
Solution:
We have,

Putting x=45, we get





Therefore, the cost to install 45 air conditioners is $60433.33.
Answer:
See explanation
Step-by-step explanation:
Consider given statement "If a figure is a cube, then it has eight vertices" in math terms. Let
- statement p be "A figure is cube.";
- statement q be "A figure has 8 vertices."
Then the statement "If a figure is a cube, then it has eight vertices" can be written as

Converse (
): If a figure has eight vertices, then it is a cube.
Inverse (
): If a figure is not a cube, then it has not eight vertices.
Contrapositive (
): If a figure has not eight vertices, then it is not a cube.
The least likely measure of central tendency to be used would be; The range.
<h3>How to identify measures of central tendency?</h3>
We are given the points scored by the basketball team as;
84, 67, 74, 87, 67, 73
Now, the three major measures of central tendency are mean, median and mode.
Mean is the average while mode is the most frequent item while median is the middle term when arranged in ascending order.
However, when discussing their year, what the paper would like to know is their average amount of points per game for the year and as such he will use the mean.
However, the least likely measure of central tendency to be used would be the range.
