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.

Answer:

The terminal point would be (1,0)

Step-by-step explanation:

Recall that in a unit circle, x° is located at the point (cosx°,sinx°) therefore the terminal point would be (cos(360°),sin(360°)) -> (1,0)

In a unit circle, it is given that 0 = 360°. The terminal point would be equal to (1,0).

The circle unit terminal Points in the unit circle to locate the terminal point, begin with (1,0).

In a unit circle, x° is located at the point (cosx°,sinx°)

In a unit circle, 0 = 360°.

therefore the terminal point would be

(cos(360°),sin(360°)) -> (1,0)

Answer:

2 2/7 + 4 1/2

Step-by-step explanation:

Exact form 95/14 for me

Mixed number will be 6 11/14

2 2/7 + 4 1/2 simplified fraction is 95/14.

To simplify the expression 2 2/7 + 4 1/2, we can convert the mixed numbers to improper fractions and then add them together.

Converting the mixed numbers to improper fractions:

2 2/7 can be written as (2 x 7 + 2)/7 = 16/7

4 1/2 can be written as (4 x 2 + 1)/2 = 9/2

Now we can add the fractions together:

16/7 + 9/2

To add fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 7 and 2 is 14.

Converting both fractions to have a denominator of 14:

16/7 x 2/2 = 32/14

9/2 x 7/7 = 63/14

Now we can add the fractions:

32/14 + 63/14 = (32 + 63)/14 = 95/14

Therefore, 2 2/7 + 4 1/2 simplified is 95/14.
