This is experimental probability.  The probability here is based on the people in the room instead of the number of people in the population.  You're taking actual physical data and conducting a probability experiment, so that makes it experimental.

Help I need one more number but I have no clue what it is!!!!!!!!!!!!!
VARVARA [1.3K]

Answer:

The point of intersection with the x axis are (-2,0) and (8,0)

Step-by-step explanation:

given circle equation x²+y² = 25

x² + y² = r²

r is the radius.

✓(25) = 5

given the center is at (3,0) and radius of 5

(3+5,0) and (3-5,0)

(8,0) and (-2,0)

(Please heart the answer if you find it helpful, it's a motivation for me to help more people)

You want to find the area of the circle. The formula for the area of a circle is A=πr^2 (Area=pi times radius squared). The diameter is the distance across the circle. Radius is half the diameter. Diameter=3. 3 divided by 2 equals 1.5. So, plug it into the equation. A=π1.5^2 (Area=pi times 1.5 squared).

What is log base 7 of 252
rjkz [21]

Answer:

2.84

Step-by-step explanation:

Recognize that 252 = 7*36

and so:

log base 7 of 252 = log base 7 of 36 + log base 7 of 7, or

                                 log base 7 of 36 + 1

So the most you can simplify log base 7 of 252 is to write 1 + log base 7 of 36.

Or, if you want to use the change of base formula, you could do the following:

                                 log 36

log base 7 of 36 = -------------- = 1.84

                                  log 7

and so log base 7 of 252 would come out to

1 + log base 7 of 36  =  1 + 1.84  = 2.84

Check:  does 7^2.84 = 252?  YES.  So we know that:

 1 + log base 7 of 36 = 2.84
