Answer:
18
Step-by-step explanation:
First, you would do a proportion
=
Then you would cross multiply, getting 50x=900.
After that, you would do 900/50, which is 18.
Answer:
4
Step-by-step explanation: 4*4 is 16. 4^2 is 16. So the square root of 16 is 4.
Answer:
40
Step-by-step explanation:
Also, you find it by multiplying.
The median of this list of numbers is 63.5 acres (not given).
The median of a set of data is the middle value. If you order the 4 numbers you have:
60 63 64 65
The middle is in between 63 and 64, therefore the median is 63.5.
Answer:
y = 1/2 x + -5
Step-by-step explanation:
Slope-intercept form is y = mx + b
where m is the slope and b is the y-intercept
m is equal to change in y/ change in x ( aka horizontal change over vertical change), in the graph the horizontal change is 1 up for every 2 units right, which equals 1/2
b is the y-intercept (when x=0), if you look at the graph x=0 when y=-5
Lastly, you put in m and b into the equation to get y = 1/2 x + -5
