Answer:
y-int: -9, slope: 3/5
Step-by-step explanation:
The answer is (C). All sides and angles of the square is equal. Its diagonals bisect each other and meet at 90°. If two lines are said to meet at 90°, these lines are perpendicular to each other. Therefore, the diagonals of a square is perpendicular to each other
Answer:
The number is equal to 10
Step-by-step explanation:
Let x be the number
4(x-3)=28
x-3=7
x=10
Answer:
Median and IQR
Step-by-step explanation:
If we are to accurately compare two data sets, the best measure of central tendency is median and best measure of variability is the MAD.
The reason is that:
1. Median is not affected by outlier or extreme value. Due to this, if we use the mean, it can be misleading if there is any case of outlier(s) in the data sets.
2. The interquartile range (IQR) is the middle half of the data. It uses the concept of median to operate - think about the median value that splits the dataset in half. Similarly, you can divide the data into quarters. This also is not affected by outlier(s) or extreme value(s).
NB: When we say middle half or middle number, we assumed you have sorted the data sets either in ascending order or descending order. This will put the data sets in order of their sizes. E.g., 1 < 2 < 3, etc.
Answer:
Step-by-step explanation:
We must convert the given temperatures from degrees Celsius to degrees Fahrenheit
The formula is:
Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit
Then we must replace the temperature in degrees Celsius and solve the equation for F
The Fahrenheit temperature range in which the antifreeze protects the car is:
