Its 5 cuz you have to divide 20 by 4 and you get 5 (20÷4=5)

"Describe the relationship between the relative frequency of the coin landing on heads and the probability of a single coin land

BigorU [14]

Answer:

The greater the sample size, the closer the percentage.

Step-by-step explanation:

<u>Relative frequency</u>

The relative frequency of an event is the division of the number of times that an event occurs during experimental trials by the total number of trials conducted.

The percentage of the relative frequency of getting Head is usually very close to the theoretical probability of getting a Head. However, results vary for each experiment.

The sample size in this case is the number of experiments carried out. The greater the sample size, the closer the percentage of Heads will be to the theoretical probability of getting a Head.

Find the solution 2x+5y=12

Ahat [919]

You can draw a graph of that equation. When you do that, the graph is a
straight line, and EVERY POINT on the line is a solution of the equation.
There are an infinite number of them.

You can find as many of them as you want. Pick any number you like
out of the air, and call it 'x'. Now find the number that's 2.4 more than
negative 0.4 of 'x' and that's 'y'. Together they form one solution to
the equation.

Brianna is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $3.75. Brianna spent $18.75 a

maxonik [38]

Answer:

6 games and 3 rides

Step-by-step explanation:

Let the number of games Brianna played be x,

and the number of rides she went on be y.

Total cost for games= 1.25x

Total cost for rides= 3.75y

Since number of games is twice the number of rides,

x= 2y -----(1)

Total costs= cost of games +cost of rides

$18.75= 1.25x +3.75y$

Multiply the whole equation by 4 to remove the decimals:

$75= 5x +15y$

Simplify by dividing the whole equation by 5:

$15 = x + 3y$

Label the equation:

x +3y= 15 -----(2)

Although we can solve these 2 equations by substitution, since the question requires us to graphically solve, we have to graph 2 linear lines.

I will choose 3 points to plot on the graph for each equation:

x= 2y -----(1)

$\begin{tabular}{|c|c|c|c|} \cline{1-4}x & 2(1) = 2&2(2) = 4&2(3) = 6\\ \cline{1-4}y & 1 &2&3\\ \cline{1-4}\end{tabular}$

x +3y= 15 -----(2)

x= -3y +15

$\begin{tabular}{|c|c|c|c|} \cline{1-4}x & -3(1)+15= 12& -3(2)+15= 9& -3(3)+15= 6\\ \cline{1-4}y & 1 &2&3\\ \cline{1-4}\end{tabular}$

Let's plot these points on a graph paper. Then, join them with a straight line for each straight line graph. Please see the attached picture for the graph.

From (1): y= ½x

From (2): 3y= 15 -x

y= 5 -⅓x

From the graph, the solution of the equation is (6,3). The solution is the point on the graph in which the 2 lines intersect.

x- coordinate: 6

y- coordinate: 3

Thus, Brianna played 6 games and went on 3 rides.
