A rhombus is a shape that has all four sides equal, whether they be in the shape of a parallelogram, or a square, if it has all four sides equal length, it's a rhombus. The definition of a rectangle, is a shape that has four right angles. (90 degrees).
So, if a square has all four sides equal, and four right angles, it can be both a rhombus and a rectangle.
Not all rhombuses are squares, because not all have four right angles. Not all rectangles are squares, because they do not all have four equal sides. Not all rectangles are rhombuses because they do not have four equal sides.
But all squares are a rhombus and all squares are a rectangle.
Answer:
<em>3x + 5</em>
Step-by-step explanation:
We are doing variables and simplifying.
You have two types of numbers here, you have a coefficient, and you have regular numbers. Now do keep in mind that you can never add a regular number to a coefficient. So the only thing in this problem you will add is 3 and 2. Because 3x is different
3x + (3 + 2)
3x + 5
Answer:
The sample size is 
Step-by-step explanation:
The population proportion is 
The margin of error is 
From the question we are told the confidence level is 90% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20)
=> ![n = [\frac{1.645 }{0.1} ]^2 * 0.50 (1 - 0.50 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.645%20%7D%7B0.1%7D%20%5D%5E2%20%2A%200.50%20%20%281%20-%200.50%20%29%20)
=>
20% of the juice is cranberry
80% of the juice is apple
Our ratio would be 20:80
We can simplify it and it will become
1:4
So your answer would be B. 1:4
I hope this helps :)
The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.
The area can be calculated in terms of known linear measurements of the circle:
-- Area = (π) x (radius)²
-- Area = (π/4) x (diameter)²
-- Area = (1/2) x (circumference) x (radius)
-- Area = (1/4) x (circumference) x (diameter)
Any of these formulas will give you the area. The one you decide to use
just depends on what you already know about the circle.
