Answer
given,
mean of women (μ)=63 inches
standard deviation of women (σ)= 2.4 inches
mean of men (μ)=70 inches
standard deviation of women (σ)= 2.5 inches
for women

To find median . . . list the number in order from least to greatest
10 , 11, 12, 12 13, 15
Then cross of a number from each side until you get to the middle number or middle 2 numbers.
IF there are 2 numbers add them together and divide by 2
12 + 12 = 24
24 / 2 = 12
Your median is 12
To find mean (this is the same as average) add all the numbers to get a total.
10 + 11 + 12 + 12 + 13 + 15 = 73
Then count the number of items added . . .6
Take the total and divide by the items counted
73 / 6 = 12.1666
Your directions say to round to the nearest tenth place.
12.166 = 12.2
0.25 is a demimal
the one to the right of that is a ratio
the one under that is equivalent fractions
the one the right of equivalent fractions is simplest form
You can do this without drawing even. Let's say the coordinates are
A, B and C, respectively, and we're looking for D.
If the other vertex is opposite A(2,1), it will be at B+C-A = (8, 11)
If the other vertex is opposite B, it will be at A+C-B = (4, -1)
If the other vertex is opposite C, it will be at A+B-C = (0, 3)
Explanation: think of one of the vertexes as a corner of the parallelogram and you want to travel to the opposite corner. That means you must add both vectors that represent the sides. So from A to D, you'd have to add (B-A) and (C-A). That gives us A+(B-A)+(C-A) simplifies to B+C-A.
Answer:
x = 3
Step-by-step explanation:
3 ( x + 1 ) = 5 ( x- 2 ) + 7
Expand
3 x + 3 = 5 x - 10 + 7
Minus 5 x from both sides
- 2 x + 3 = - 10 + 7
Minus 3 from both sides
- 2 x = - 10 + 4
Simplify
- 2 x = - 6
Divide both sides by - 2
x = 3
