Ratios are used to compare quantities of different measures
<u>Forms</u>
Ratios are represented in any of the following forms
- Ratio = a : b
- Ratio = a / b
For three quantities, the ratio would be
<u>Examples</u>
Assume the proportion of milk and chocolate is 1 to 2.
The ratio would be represented as:
Other possible examples are:
- Water : Honey = 5 : 3
- Rice : Beans = 4 : 1

Okay nvm the answer is wrong, my life has ended
This can be solved by using the normal approximation to the binomial distribution.
mean = np = 10.000 * 0.5 = 5,000
The standard deviation is given by:
![S.D.= \sqrt{npq} = \sqrt{5000\times0.5} =50](https://tex.z-dn.net/?f=S.D.%3D%20%5Csqrt%7Bnpq%7D%20%3D%20%5Csqrt%7B5000%5Ctimes0.5%7D%20%3D50)
![z=\frac{5100-5000}{50}=2](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B5100-5000%7D%7B50%7D%3D2)
The probability of obtaining more than 5100 tails is 0.0228 and the probability of obtaining fewer than 5100 tails is 0.9772.
The odds of obtaining more than 5100 tails is therefore:
0.0228:0.9772 = 1:42.86.
Answer:
Step-by-step explanation:
points that lie on an axis do not lie in any quadrant.
So point A lies in the positive x-axis
The origin (0,0) does't lie on any quadrant.
Origin is the point that lies on both x-axis and y-axis
Answer:
l = 15 feet
Step-by-step explanation:
l = 2w + 3
First you solve for the width(w)
(2w+15) (w-6) = 0
This means
2w+15=0 OR. w-6=0
First let’s solve 2w+15=0
2w = -15
w = -7.5
Width can’t be negative so that can’t be the answer. So we look at the second equation w-6=0
w= 6
Since we found the width now we can find the length by using the formula l = 2w + 3
= 2(6) + 3
= 12 + 3
= 15 feet
You can check this by using the given area which is 90.
A = lw = 15*6 = 90
