Answer:
Step-by-step explanation:
If she doubles the area of her lot, it should be 2x^2.
But how do you get that?
The answer is that the sides have now increased to √2x
How did I get that, and why did I choose it?
- The formula for a square's area is s^2
- If you want to double the area, it will be 2 s^2. Now what?
- Take the square root of 2s^2 which is √(2s^2).
- What that means is the side is now √2 s
Answer:
5 1/3
Step-by-step explanation:
Set up ratio.
2/3 cup orange juice X 2 cups pineapple juice
———————————-
1/4 cup pineapple juice
first multiply numerator : 2/3 x 2 = 4/3
and divide by denominator
(4/3)/(1/4). Keep the first. Change the sign to multiplication and Flip the second fraction.
4/3 x 4/1 = 16/3
change to proper fraction : 16/3 = 5 1/3 cups

Answer:
Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .
Step-by-step explanation:
We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.
The distribution we can use here is;
~ N(0,1)
where, p = 0.20 and n = 100
Let 
= proportion of red candies in our sample
So, P( < 0.20) = P( < 
) = P(Z < 0) = 0.5
Therefore, probability that the proportion in our sample of red candies will be less than 20% is 0.5 .
