To solve this problem, we need to use the distance formula.

Distance = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}

x1 = -9

x2 = 2

y1 = -7

y2 = -6

Plug your numbers in

Distance = \sqrt{((2) - (-9))^2 + ((-6) - (-7))^2}. Simplify each parenthesis.

Distance = \sqrt{121 + 1}. Add these numbers together and take the square root.

Distance = √(122) or 11.05 units.

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:

A ticket for a seat at a village parish play costs £3.95 There are 17 rows of seats. There are 29 seats in each row. The village
Tcecarenko [31]

Answer:

Total money earned = £1,947.35

Step-by-step explanation:

Given:

Per ticket cost = £3.95

Number of rows = 17

Number of seats in each row = 29 seats

Find:

Total money earned.

Computation:

Total number of seats = Number of rows × Number of seats in each row

Total number of seats = 17 × 29

Total number of seats = 493 seats

Total money earned = Total number of seats × Per ticket cost

Total money earned = 493 × £3.95

Total money earned = £1,947.35
