The total cost of the bracelet will be $96.

The number of charms will be 2.

Step-by-step explanation:

Given,

Cost per charm at Dayton Fine Jewelry = $17

Cost of bracelet = $62

Let,

x be the number of charms

y be the total cost

y = 17x+62 Eqn 1

Cost per charm at Cain Jewelers = $18

Cost of bracelet = $60

y = 18x+60 Eqn 2

For same cost;

Eqn 1 = Eqn 2

$17x+62=18x+60\\62-60=18x-17x\\2=x\\x=2$

Putting x=2 in Eqn 1

$y=17(2)+62\\y=34+62\\y=96$

Putting x=2 in Eqn 2

$y=18(2) +60\\y=36+60\\y=96$

The total cost of the bracelet will be $96.

The number of charms will be 2.

A restaurant decides to test their oven's thermostat to see if it is working properly, that is, if the actual temperature inside

Taya2010 [7]

Answer:

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

With n = 20 and represent the mean temperature of the oven

The correct option for this case is:

mu = the true mean temperature of the oven xbar = the true mean temperature of the oven

Step-by-step explanation:

Previous concepts

Parameter represent a property of a population and is calculated with the information of all the populatio. Some examples are the population mean and deviation $\mu,\sigma$

Statistic represent a propoerty of a sample and are used used in order to describe the population parameters, since represent estimators of the real parameters.

Solution to the problem

For this case we have information from a sample of n =20 times of temperatures of the oven

The parameter of interest is $\mu$ population temperature mean of the oven

And the statistic is calculated with this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$
