Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2
1.An appliance store sells major appliances (such as dishwashers, washing machines, dryers); for an additional fee, the store offers an extended service contract beyond the warranty period. The owner of this appliance store notes that she sold 145 dishwashers during the past 6 months; 45% of these customers also purchased the extended service contract. To maintain customer relations, the owner likes to contact her customers to see how they are enjoying their new appliances. She conducts a random sample of 35 of these customers. a)What is the probability that fewer than 40% of the customers in the sample purchased the service contract
Answer:
0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
45% of these customers also purchased the extended service contract.
This means that [tex]p = 0.45[/tex]
Sample of 35
This means that [tex]n = 35[/tex]
Mean and standard deviation:
[tex]\mu = 0.45[/tex]
[tex]s = \sqrt{\frac{0.45*0.55}{35}} = 0.0841[/tex]
What is the probability that fewer than 40% of the customers in the sample purchased the service contract?
This is the p-value of Z when X = 0.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.4 - 0.45}{0.0841}[/tex]
[tex]Z = -0.59[/tex]
[tex]Z = -0.59[/tex] has a p-value of 0.2776
0.2776 = 27.76% probability that fewer than 40% of the customers in the sample purchased the service contract.
