Darrin tosses a quarter and a penny 20 times. He gets heads on both coins twice. Compare the theoretical probability of getting

heads on both coins with Darrin’s experimental probability of getting heads on both coins. Why might the probabilities differ?

Answer:

The theoretical probability is that it will be Heads Heads 25% of the time. However, the experimental probability is 10%.

Step-by-step explanation:

The main difference between experimental and theoretical probability is that experimental probability is based on the actual results of an experiment. In contrast, the theoretical probability is based on possible outcomes based on assumptions.

a plate has a raduis of 3 inches what is the best approximation for the circumference of the plate ? use 3.14 to approimate pi.​
kozerog [31]

Answer:

Best approximation for the circumference of the plate = 18.84 inches

Step-by-step explanation:

Given in the question,

radius of a plate = 3 inches

π  = 3.14

To find,

circumference of the plate.

As we know that formula to calculate circumference of a circle given radius

<h2>2 π r</h2>

2 (π) (3)

2 (3.14) (3)

18.84 inches

So the circumference or perimeter of area = 18.84 inches

Tell whether the ordered pair is a solution of the given system. (-2,-4) {y=1/2x -3, y=-2x-8}
kompoz [17]

Answer:

The ordered pair (-2,\, -4) is indeed a solution to the system:

\left\lbrace\begin{aligned} & y = \frac{1}{2}\, x - 3 \\ & y = -2\, x - 8\end{aligned}\right..

Step-by-step explanation:

Consider a system of equations about variables x and y. An ordered pair (x_{0},\, y_{0}) (where x_{0} and y_{0} are constant) is a solution to that system if and only if all equations in that system hold after substituting in x = x_{0} and y = y_{0}.

For the system in this question, (-2,\, -4) would be a solution only if both equations in the system hold after replacing all x in equations of the system with (-2) and all y with (-4).

The \texttt{LHS} of the equation y = (1/2)\, x - 3 would become (-4). The \texttt{RHS} of that equation would become (1/2) \, (-2) - 3. The two sides are indeed equal.

Similarly, the \texttt{LHS} of the equation y = -2\, x - 8 would become (-4). The \texttt{RHS} of that equation would become (-2)\, (-2) - 8. The two sides are indeed equal.

Thus, x = (-2) and y = (-4) simultaneously satisfy both equations of the given system. Therefore, the ordered pair (-2,\, -4) would indeed be a solution to that system.
