Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
Hope this helps!
Here are the answers:
1.) DC=D’C’
2.) 3.) ED=E’D’
answer:
2,558
step-by-step explanation:
the formula for the volume of a cone is v=πr²h/3
with that let us 'fill in' the formula-
v=π*9.6²*26.5/3
v=2,557.51
then since you've asked us to round the answer to the nearest whole number that would be 2,558
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!

Answer: y=-3/4x-2
Step-by-step explanation:
Write an equation of a line in slope-intercept from with the given slope, slope:–3/4, y-intercept: –2
The y-intercept is at (0,-2)
Then we write the equation using y=mx+b becuase that is the point slope form.
m=-3/4 which was given in the question
because y-intercept is at (0,-2)
y=-2
x=0
-2=-3/4(0)+b
-2=0+b
-2=b
now we know that m is -3/4 and b is -2
Hence the equation is y=-3/4x-2
