Answer:
A square that has sides of 4.5 units, or a rectangle that is 1 unit wide and 8 units long.
Step-by-step explanation:
First, you need to find the perimeter in the first place. Since there are two sides of the same number, you would double each number.
2 would become 4
6 would become 12
Add 4+12=18
So, our rectangle has to have a perimeter of 18 units. Because a square is a rectangle, you can divide 18 and 4, since a square has 4 sides. You get 4.5. Each side can be 4.5 units.
Or, you can have a rectangle. What I thought first was a length of 9, but I knew that wouldn't work. I drew a rectangle and tried 8. If I put it on the top and bottom, which you need to to find the perimeter, it was only 16. Then I knew I could use 1 as a side length. If you added the sides, it would equal 2, and when you add 16 and 2, it's 18. So, you can use a rectangle that has a length of 8 units and a width of 1 unit.
Answer:
13:7
Step-by-step explanation:
We see that the ratio from women:children is 13:4.
Therefore, the number of women is 13.
In the ratio comparing men to children we see that it is 7:3.
Therefore, the number of men is 7.
Now we need to compare the number of women to the number of men which is 13:7.
The answer should be C. Examples of mixed numbers: 1 2/3; 3 6/7; 2 12/18. Hope this helps. Note: If I’m right can I have brainliest ?
Solving for x right?
2) 6x + 4 = 3x - 1
6x - 3x = -1 - 4
3x = -5
x = - 5/3
3) x - 9 = 3/5x
5(x-9) = 3x
5x - 45 = 3x
2x = 45
x = 45/2
Answer:
Step-by-step explanation:
n = 400
Proportion p = 229/400= 0.5725
For 95% confidence interval we use Z value as 1.96
Std error = 0.025
margin of error = 1.96*0.025
Confidence interval 95% = 0.5725±Margin of error
= (0.524, 0.621)
b) When smiled x becomes 277
p = 0.6925
Std error = 0.023
Margin of error= 1.96*0.023
Confidence interval = (0.647, 0.738)
Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.
