Answer:

A. 6%

B. 14%

C. 80%

Step-by-step explanation:

Typically the easiest way to think of probability problems is with the "formula"

probability = part ÷ whole.

The "whole" part of the earlier formula is the total number of times the cup was flipped ("whole" = 50).

The "part" portion of the formula is the number of times that result occurred ("part" = 3, 7, and 40).

A. The probability of the open side up result is probability = 3÷50 = 0.06 = 6%.

B. The probability of the closed side up result is probability = 7÷50 = 0.14 = 14%.

C. The probability of the landing on side result is probability = 40÷50 = 0.8 = 80%.

Answer:

3/50 7/50 40/50

Step-by-step explanation:

Ok. I'm not exactly a math wiz but I think you may be overthinking this. Experimental probability should be the probability from the experiment right. It's in the name. In chemistry if it's a well established value it's called a theoretical value or probability. So the answer should just be the probability from the said experiment. No other funky math terms are given here which clues me to the idea that it might just be this simple.

If you would like to know how many hours did Eric practice the piano this week, you can calculate this using the following steps:

the piano: 3/4 of 8 hours = 3/4 * 8 hours = 6 hours

The correct result would be 6 hours.

astraxan [27]

Answer:

The difference in the lengths of the two alligators = 3

Step-by-step explanation:

First, let us make the lengths improper fractions, then we will find the difference from there.

Alligator 1:

Length = $14\frac{5}{12} = \frac{173}{12}$

To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]

Alligator 2:

Length = $17\frac{5}{12} = \frac{209}{12}$

Now Let us find the difference between the lengths:

$\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3$

Therefore the difference in the lengths of the two alligators = 3

The diameter of a circle has endpoints P(-6,-11 ) and Q(4, 7). Write an equation for the circle. Be sure to show and explain all

MrMuchimi

Answer:

(x + 1)^2 + (y + 2)^2 = 106

Step-by-step explanation:

The formula for a circle is

(x - h)^2 + (y - k)^2 = r^2

Where (h, k) is the center of the circle and r is the raadius

--------------------------------------

The center is the midpoint of the diameter end points

(h, k) = ( (-6 + 4)/2 , (-11 + 7)/2 )

(h, k) = (-1, -2)

The radius is the distance from the center to an endpoint

Using (h, k) and Q

r^2 = (4 - -1)^2 + (7 - -2)^2

r^2 = 5^2 + 9^2

r^2 = 106

-------------------------------

Plug into the circle formula

(x + 1)^2 + (y + 2)^2 = 106
