Step-by-step explanation:

The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.

1. new price = .4 (.4 * original price x)

72 = .16x

2. new price = .75 (.75 * original price x)

72 = .5625x

x = 128

A population of values his normal distribution with men equal to 27.6 and standard deviation equal 39.4 do you intend to draw a

Alecsey [184]

Answer:

The mean of the distribution of sample means is 27.6

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 27.6

Standard Deviation, σ = 39.4

We are given that the population is a bell shaped distribution that is a normal distribution.

Sample size, n = 173.

We have to find the mean of the distribution of sample means.

Central Limit theorem:

It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
The mean of all samples from the same population will be approximately equal to the mean of the population.

Thus, we can write:

$\mu_{\bar{x}} = \mu = 27.6$

Thus, the mean of the distribution of sample means is 27.6

Javier's employer pays for 43% of his annual health insurance premium. javier pays the remaining balance by having it deducted f

mihalych1998 [28]

<span>Let us start with the percentage of premium paid by Javier. Since the employer pays 43%, the remaining 57% (100-43) is paid by Javier. Now let us find out how much is deducted from his paychecks during the year. In one month, $157.38 x 2 = $314 .76 is deducted by the employer. So in 12 months, the amount equal to 57% of the health premium will be $314.76 x 12 = $3777.12. If $ 3777.12 is 57% of a certain number, to find the number, multiply $3777.12 with the reciprocal of the fraction. (57/100) So the unknown number = $3777.12 * 100/57 = $6626.53 Javier's total annual health premium, therefore, is $6626.53</span>
