Answer:

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4

Step-by-step explanation:

We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.

The total value of all the slips when added together is:

= (8)(2) + (2)(4)  

=  16 + 8 = 24

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4  ....

If the circumference of a circle measures 25.12cm, what is the area of the circle in terms of pi?
kiruha [24]

Answer:

Step-by-step explanation:

The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.

Circumfrance is 25.12 so....

25.12 = 2 * (pi) R........ you want to find R because you need it to find the area

R is about 4; it is 3.99797 .

You use the R that you goot from cirdumfrance to find area.

Area = (pi) (4)^2 = 50. 265

or is you prefer a more precise answer, Area = 50.2145

The graph of a proportional relationship passes through the points (15,3) and (5,y). Find y.
snow_tiger [21]
Y is equal to 1 because to change 15 into 5 you have to divide by 3. 15/3=5. So you do the same to the other coordinate. Divide 3 by 3 to get 1.
