Answer:
Percentage of gold bangles is 66.6 and of silver bangles it is 33.3
Step-by-step explanation:
Given:
Number of gold bangles Mala has = 
Number of silver bangles she has = 
Total number of bangles = 
= 
We have to find the percentage of each type of bangles.
So,
Percentage of bangles = 
- Percentage of gold bangles.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
- Percentage of silver bangles.
⇒ 
⇒ 
Percentage of gold bangles, Mala has = 66.6 and of silver bangles it is = 33.3
3x+1+52 = 180°
Remember, angles in a straight line must ALWAYS add up to 180°.

Answer:
The probability that in a random sample of 100 CSU graduates the error is within 5% of the population proportion of 60% is 0.6923.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The information provided is:
<em>p</em> = 0.60
<em>n</em> = 100
As <em>n</em> = 100 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample proportions.
The distribution of sample proportion is 
.
Compute the probability that in a random sample of 100 CSU graduates the error is within 5% of the population proportion of 60% as follows:
Thus, the probability that in a random sample of 100 CSU graduates the error is within 5% of the population proportion of 60% is 0.6923.
