In a sample of 77 children , the mean age as at which they first began to combine words was 16.51 months
astraxan [27]

Answer:

Mean age = 1271.27

Step-by-step explanation:

No of children = 77

The age at which children first began to combine words = 16.51 months

Mean age = No of children × age at which children first began to combine words

                = 77 × 16.51

                 = 1271.27

Mean age = 1271.27

Please help! I can't seem to figure this stuff out...
Fudgin [204]
1: always rearrange the equation to y = mx + c so....
x - y = o

x = y

So the gradient is 1 and it intersects the y axis at (0,0)

The three points could be (1,1), (2,2), (3,3) and so on



2: -x -2y = -10
Multiply everything by -1

x + 2y = 10

2y = 10 - x

y = 5 - x/2

The y intercept is 5 so you could use the point (0,5), (2,4), (4,3) and so on



3: x + y = -2

y = -2 - x

The y intercept is -2 so you could use the points (0,-2), (2,-4), (3,-5) and so on



4: -3y =-x -7

Multiply everything by -1

3y = x + 7

y = x/3 + 7/3

The y intercept is 7/3 so you could use the points (0,7/3), (3,10/3), (6,13/3) and so o



5: -y = -x + 1

y = x - 1

The y intercept is -1 so you could use the points (0,-1), (2,1), (3,2) and so on


Hope this helps! Any questions let me know :)
