Answer:
Step-by-step explanation:
This is simple: we need to only do 2 steps
1) Convert to feet
2) Get the area
1) Converting to feet is just
(ignore the use of this it's just to show the differnt things to multiply
Now we have a length of 21 and a width of 12 FEET.
2) To solve for the area, we need to multiply both dimensions.
So the answer is 252^2 FEET (DONT FORGET THE UNIT SQUARE FEET)
Answer:
y = -3x - 6
Step-by-step explanation:
first, find the slope
(-4, 6)
(1, -9)
remember the equation for the slope
insert given points
((-9) - (6)) / ((1) - (-4))
simplify
( -9 - 6) / (1 + 4)
= -15/ 5
= -3
now insert it into the equation of the line
remember, the equation of the line is
y = mx + b
where "m" is the slope
and "b" is the y-intercept
to find "b", you just have to plug in a point that is found on the line
we know that (-4, 6) and (1. -9) is found on the line, so let's just use (-4, 6) for this problem
y = mx + b
substitute in the slope of this line
y = -3x + b
now substitute in the given points
6 = -3 * -4 + b
and solve it like any algebra problem, by inverse operations and simplifying
6 = 12 + b
-12 -12
-6 = b
so the equation of the line is
y = -3x -6
Answer:
Step-by-step explanation:
5,9,11,(13,16),16,19,21
the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5
Q1 = (9 + 11) / 2 = 20/2 = 10
Q3 = (16 + 19) / 2 = 35/2 = 17.5
interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==
