A bird was perched on a tree at a height of 19 feet. The bird then saw food on a branch below and dropped down 7 1/2 feet. What

solmaris [256]

Answer:

11 1/2 feet

Step-by-step explanation:

You simply subtract 19 and 7 1/2 because the bird dropped down which means it is closer to the ground, therefore, subtracting its original height at 19 feet. Hope that helped.

<h3>What is an inequality?</h3>

An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

Less than (<).

Greater than (>).

Less than or equal to (≤).

Greater than or equal to (≥).

Given the following system of inequalities:

3y > 2x + 12 ⇒ 3y - 2x > 12

2x + y ≤ -5

By using Geogebra online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

1.) Any measure representing the center of a set of data arranged in a decreasing or increasing order of magnitude.

Marrrta [24]

Answer: The median is defined the measure of the central value when arranged in ascending or descending order of magnitude.
An average is a single number that represents the “middle” value of all the numbers in a list or set. There are three different types of average. These are called the mean, the median, and the mode.
When the given data is arranged in ascending (or descending) order, then the middle most observation is the median of the data. Mean, median and mode are the representative values of a group of observations. They are also called the measures of central tendency of the data.
If there are two numbers that appear most often (and the same number of times) then the data has two modes. This is called bimodal. If there are more than 2 then the data would be called multimodal. If all the numbers appear the same number of times, then the data set has no modes.
mode
The median is the middle score in a set of given numbers. The mode is the most frequently occurring score in a set of given numbers.
