Answer: 123.5 centimeters
Step-by-step explanation:
Let sum of observations be S and number of observations be n.
Average A=
The average height of 4 children is (15h-3)
Also, when two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters the sum of heights of 6 children will be
Now, Average height of 6 students=
At h=9
Average height of 6 students=
We know that
[perimeter of rectangle]=2*(<span>length+width)
</span>
Let
x-----------> length
y-----------> width
so
P=2*(x+y)-----------> 244=2*(x+y)-----> x+y=122-------> y=122-x
Area=x*y-------> x*(122-x)----> 122x-x²
find the derivative function and equals to zero
122-2x=0-----> 122=2x----------> x=61 m
y=122-x------> y=122-61---------> y=61 m
<span>the maximum area is given by a square
</span>
the answer is
is a square of side 61 m
Answer: y=3
Step-by-step explanation:
first, you need to find the slope using the slope formula (y2-y1/x2-x1)
-4--4/6--7 = 0/13 which equals 0
now you fill it into the point-slope form (y=m(x-x1)+y1)
y=0(x--7)-4
you distribute and get
y=3
Answer:
c. x = 27
Step-by-step explanation:
-11 + 1/3 x + 9 = 7
1/3 x - 2 = 7
1/3 x = 9
x = 27
