The mean of four numbers is 43. What are those four numbers?​

Mathematics
1 answer:
Andrej [43]3 years ago
7 0

Answer:

42,43,43,44

Step-by-step explanation:

If there are four numbers in a list then the middle 2 numbers should be added up and divided up to give the mean. If we are given the mean we can now work backwards to give us:

\frac{x+y}{2} (where x and y are the 2 middle numbers)

We can also see that x and y must be equal as the mean is an integer.

So:

43=\frac{2x}{2}

So x=43 and that is the middle 2 numbers.

I don't exactly know how to explain how i got the other 2 numbers.

Is the figure an example of a segment?
Radda [10]

Answer: yes, it extends infinitely in opposite directions

Step-by-step explanation:

Examples of line segments include the sides of a triangle or square. More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or otherwise a diagonal.

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y r
Ratling [72]
Y > x
y = 2(3+x)
y = 3x-2
------------------------------
2(3+x) = 3x-2
2(3+x) - (3x-2) = 0
6 + 2x -3x + 2 = 0
8 -x = 0
x = 8
---------------------------
y = 2(3+x) = 2(3+8) = 22
y = 3x-2 = 3*8 -2 = 22
----------------------------------
x = 8 ; y = 22

Find the surface area of the triangular prism shown below .
Wewaii [24]

Answer:

the surface area should be 544 (whatever the unit is)

Step-by-step explanation:

You start by taking the rectangles on the side and finding their area.

1. (10×14)×2 ←Because there are two rectanglular sides.

2. find the area of the triangles on the side. 1/2bh = area of triangle.

(.5×8×6)×4 ← in order to find the area for all of the triangles.

3.  lastly take the base of the prism and find the area then add the previously found values together.

(12×14)+(.5×8×6)×4+ (10×14)×2 = 544
