Step-by-step explanation:

In circle with centre O, TN is tangent at E.

$\therefore OE \perp TN\\\\\therefore m\angle OET = m\angle OEN= 90\degree \\\\In\: \triangle OET\\\\\angle OET + \angle OTE +\angle TOE = 180°\\\\\therefore 90\degree + 35\degree+\angle TOE = 180°\\\\\therefore 125\degree+\angle TOE = 180\degree\\\\\therefore \angle TOE = 180\degree-125\degree\\\\\huge \red {\boxed{\therefore \angle TOE = 55\degree}} \\\\In\: \triangle OPE\\\\OP = OE... (radii\: of \:same \: circle) \\\\\therefore \angle OPE = \angle OEP..(1)\\ (\angle s \: opposite \: to \:equal\:sides) \\\\\angle TOE =\angle OPE +\angle OEP.. (2)\\(by\:exterior \:\angle\:theorem) \\\\\therefore 55\degree= \angle OPE +\angle OPE\\\{From\: equations\:(1) \&\:(2)\} \\\\\therefore 55\degree= 2\angle OPE \\\\\therefore \angle OPE = \frac{55\degree}{2}\\\\\huge \orange{\boxed{\therefore \angle OPE =27.5\degree}}$

25 730 to nearest thousand

Agata [3.3K]

If you round 25,730 to the nearest thousand, you should look at the digit directly before the thousands digit, which, in this case, is 7. In mathematics, if the digit is equal to or greater than 5, you should round upwards. Since 7 is greater than 5, the answer to this problem is 26,000.

An analyst for a large credit card company is going to conduct a survey of customers to examine their household characteristics.

zheka24 [161]

Answer:

We can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.

Step-by-step explanation:

Previous concepts

A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation

A parameter is "any numerical quantity that characterizes a given population or some aspect of it".

Solution to the problem

For this case the analyst knows that from previous records that the mean for all the customers (that represent the population of interest) is $\mu = 1622$

He have a random sample of n =500 customers from the previous month and he knows that 1732 represent the sample mean for the selected customers calculated from the following formula:

$\bar X = \frac{\sum_{i=1}^{500} X_i}{500}= 1732$

So on this case we can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.

In a city it snowed 3/5 meter on Saturday and 1/5 meter on Sunday how much more snow is needed on Monday to reach a total of 1 m

yawa3891 [41]

You do 4/5+1/5=4/5 and then you do 5/5-4/5=1/5 of a meter is needed.
