Linear mathematical models describe real world applications with the use lines. For instance, a car going 50 mph, has traveled a distance represented by y=50x, where x is time in hours and y is miles. The equation and graph can be used to make predictions.
3. Greater than
Median is the middle number of the data set. But in this senario, there are 2 numbers in the middle. So you can take 4+5/2=4.5
To find Mean, you can must take all the numbers in the data set divided by the number of data collected.
In this case, (3+3+4+5+5+9)÷6
You will find that the mean is greater than the median.
Answer:
It's not very high
Step-by-step explanation:
The angle that the string and the ground maje, is acute, because it's smaller than a right angle. So, since it is an acute angle, it's not very high. It is about 30cm high.
3x + 4y = 0
3x = -4y
x = 4y/3
5x - 6y = -38
(5*4y/3) - 6y = -38
(20y/3) - 6y = -38
(20y - 18y) / 3 = -38
2y = -114
y = -57
x = 76
Answer:
Algebra -> Percentage-and-ratio-word-problems-> SOLUTION: A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 55% off clearance items
A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 55% off clearance items. 0.75(0.45) = 0.3 + 0.0375 = 0.3375. One ends up paying 33.75% of the original price.
