There are six red marbles and 11 orange marbles in a bag.  you randomly choose one of the marvelous. What is the theoretical probability of choosing a red marble?
( on a time limit so PLEASEE hurry)

Answers

Answer 1

Given:

Number of red marbles = 6

Number of orange marbles = 11

To find:

The theoretical probability of choosing a red marble.

Solution:

We have,

Number of red marbles = 6

Number of orange marbles = 11

Either we can select a red marble or orange marble.

Total types of marbles (Red and orange) = 2

So, the theoretical probability of choosing a red marble is:

[tex]P=\dfrac{1}{2}[/tex]

[tex]P=0.5[/tex]

Therefore, the theoretical probability of choosing a red marble is 0.5.

[tex] \sin(x) = \frac{7}{15} \\ x = { \sin}^{ - 1} ( \frac{7}{15} ) \\ x = 27.8 \degree[/tex]

Answer:

28°

Step-by-step explanation:

For this problem, we are given the leg length opposite the angle x and the hypotenuse. This perfectly describes the trig function, sine. We can set up an equation:

opposite / hypotenuse = sin(x°)

We can substitute in the sides:

7 / 15 = sin(x°)

Now, to find x, we can evaluate the inverse of sin or arcsin on the ratio 7 / 15

arcsin(7 / 15) = x° = 27.81813928°

This rounds to 28°

The surface area is the 2-dimensional distance around a 3-dimensional figure. In essence, if one was going to wrap a figure in paper, the surface area is the amount of paper one would need. To calculate the surface area one needs to find the area of each face of the figure, then add up all of the values.

How do you Write a problem in Standard Form?

Answers

Answer:

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000

Step-by-step explanation:

First, Switch sides,

y-y^1=m\left(x-x^1)

Second, apply the rule a^1=a

y^1=y

m(x-x^1)=y-y

Third, add similar elements: y-y=0,

m(x-x^1)=0

Fourth, using the Zero Factor Principle: If ab=0 then a=0 or b=0

x-x^1=0

Finally, simplify,

0=0
