Answer:

This is called a sample.

In statistics, we take a random 'sample' of people so that we can estimate values for the entire population!

So, say for example you want to find out what percent of students in your school are girls. You take a sample, like this again, of 30 students, and 3/10 are girls, then you can apply it to the rest of the population.

Hope this helps!

P.S. Stay Safe!

Identify the transformations that describe the graph of an even function. Select all that apply.
Bingel [31]
The function becomes even when  f(-x) = f(x)
So, if f is even function and y = f(x)
∴ y = f(-x)
∴ (x,y) and (-x,y) on the same graph
or we can say (-x,y) is an image for (x,y)
So, the rule of transformation becomes (x,y) ⇒⇒⇒ (-x,y)
Which is the same rule of <span>reflection over the y-axis.

∴ The correct choice is the second option

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

                                                        =\frac{65}{100}*80*100\\\\= 65*80\\= 5200

Amount paid for next 50 watches = (55% of 80) * 50

                                                        = \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200

Remaining watches = 280 -(100+ 55)

                                 = 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

                                                  = \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500

Amount received by the watch maker = 5200 + 2200 + 4500

                                                               = £ 11900

First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km

Divide this distance by Allan's average speed to get his average time.

42.165 km / 12 km/hr = 3.514 hours
