Step-by-step explanation:

a probability is always

desired cases / total possible cases.

there is the theoretical probability in such cases, where we simply assume that all sides of such a die (or solid) truly have the same probability.

and then we have experimental probability, where we use only the actual data we got in the experiments to calculate the probability of that particular die (with all its actual internal imperfections) to roll certain results.

so, in our experiments how many total cases do we have ?

200.

how many desired cases (a number greater than 10, that means 11 or 12 as result) do we have ?

well, the sum of all appearances of 11s and 12s :

16 + 18 = 34

that means our experimental probability to get a number greater than 10 is

34/200 = 17/100 = 0.17

FYI

while the theoretical probability with an ideal die is

total cases : 12 (1 .. 12)

desired cases : 2 (11, 12)

the probability is

2/12 = 1/6 = 0.166666666...

it is actually a tiny little bit lower than what we observed in the experiments.

Adrianna runs up 4.5 flights of stairs. How far will Arianna have to run down to represent an additive inverse?

Mashutka [201]

Answer:

She needs to run down 4.5 flights of stairs to represent an additive inverse

Step-by-step explanation:

Having an additive inverse means that she will be back at point zero.

The point zero in this context simply refer to her starting point.

So if she has run up 4.5 flights of stairs, then to be back at her starting point, she needs to run down also 4.5 flights of stairs

Which number is IRRATIONAL? A) 47 B) 0.09 C) 15 D) 8 45

Elanso [62]

Your answer would be B. 0.09, the reason being is that any number that has a 0 and then a decimal point is irrational (or a regular fraction

(HELP ME )Jolie played dodgeball in PE. In one game, Jolie threw a total of 75 balls at her

ollegr [7]

Answer:

40%

Step-by-step explanation:

A percent is;

$\frac{part}{whole} = \frac{x}{100}$

It is given that Jolie the 75 dodgeballs in total, hence the whole is 75. It is also given that 30 of the dodgeballs hit the target, so the part is 30. Now all one has to do is solve for "x".

$\frac{30}{75} = \frac{x}{100}$

Simplify $\frac{30}{75}$ by dividing the numerator and denominator by 15.

$\frac{2}{5}$

Now the equation is;

$\frac{2}{5}=\frac{x}{100}$

Typically, one would solve a proportion by doing cross products, but in this case, it is easier to think about it intuitively. Since 5 is a factor of 100 (5 * 20 = 100), then all one has to do is multiply $\frac{2}{5}$ by 20 to get the answer (on the numerator).

x = 40
