The probability helps us to know the chances of an event occurring. The number of possible outcomes When Denato pulls a pen from the bag is 29.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that the bag has 8 red pens, 7 blue pens, and 14 black pens. Therefore, if Denato will pull a pen from the bag the number of possibilities will be the sum of all the number of pens.
Number of Possibilities = 8 + 7 + 14 = 29
Thus, the number of possible outcomes When Denato pulls a pen from the bag is 29.

Ex plane how knowing 50 x 4 = 200 helps you find 500 x 400
Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so

Step-by-step explanation:
if cos(x)=-1/4 and tan(x)<0 what is sin(2x)
By definition of tangent,
tan(x) = sin(x) / cos(x)
so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.
Recall the Pythagorean identity:
cos²(x) + sin²(x) = 1 → sin(x) = + √(1 - cos²(x))
Then
sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4
Recall the double angle identity:
sin(2x) = 2 sin(x) cos(x)
Then
sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8

You are measuring temperature using a thermometer that gives degrees in Fahrenheit. You want to know what the temperature is in degrees Celsius. This formula converts temperatures from degrees Celsius to degrees Fahrenheit: F = 9/5 C + 32. Rewrite this formula to convert Fahrenheit to Celsius. In your answer, use fractions instead of decimal numbers.
Answer:
C = 5/9(F - 32)
Step-by-step explanation:
Given:
F = 9/5 C + 32
Convert Fahrenheit to Celsius:
Computation:
F = 9/5 C + 32
F - 32 = 9/5 C
5[F - 32] = 9C
C = 5/9(F - 32)
A student solves the following equation and determines that the solution is −2. Is the student correct? Explain.
3/a + 2 − 6a/a2 − 4 = 1/a − 2
Answer:
No, the student did not check the solution to the derived equation in the original equation.
No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.
No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.
Step-by-step explanation:
just did on edge good luck!
The student is wrong in his answer to the equation
3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.
3/a + 2 - 3 - 4 = 1/a - 2.
3/a - 1/a = 3.
2/a = 3.
a/2 = 1/3.
a = 2/3.

The spoke of a wheel is 35 cm. How far does the wheel travel in 1 rotation. Give your answer in meters and use pi = 22/7.
Answer:
2.2 m
Step-by-step explanation:
Assuming that spoke refers to the radius (r) of the wheel, you can determine the circumference of the wheel using 2(pi)(r).
2 x (22/7) x 35cm
= 220cm
As this answer is in cm, it needs to be converted to m to be a correct answer. As 1m = 100cm, 220cm x 0.01 = 2.2m

A factor is a number that divides another number, leaving no remainder
The highest common factor of 18, 12, and 56 using prime factors is 2.
What is a factor?A factor is a number that divides another number, leaving no remainder
Example: 12 = 4 x 3 where 4 and 3 are the factors of 12.
We have,
18, 12, and 56
The factors of each number are:
18 = 2 x 9, 3 x 6, 18 x 1
So the factors of 18 are 2, 3, 6, 9, and 18.
12 = 2 x 6, 3 x 4, 12 x 1
So the factors of 12 are 2, 3, 4, 6, and 12.
56 = 2 x 28, 4 x 14, 7 x 8, 14 x 4
So the factors of 56 are 2, 4, 7, 8, 14, and 28.
Thus,
The highest common factor of 18, 12, and 56 using prime factors is 2.

The formula should be the same. most likely
15x + 5y = 20 y = 8 - 3x
Answer:
Step-by-step explanation:
15x+5y=8-3x
18x+5y=8⇒eqn 1
15x+5y=20y
15x-15y=0⇒eqn 2
eqn 1 * 3
54x + 15y=24⇒eqn 3
eqn 3 + eqn 2
69x=24
x=24/69=0.3478
eqn 1⇒
5y=8-18(24/69)
y=1.7391/5
y=0.3478
The solution to the system of equations is (10/3, -2).
What is an equation?Two or more expressions with an equal sign are defined as an equation.
The given equations are 15x + 5y = 20 and y = 8-3x.
15x + 15y = 20
Substitute y = 8-3x into the above equation:
15x + 15(8-3x) = 20
15x + 120 - 45x = 20
45x - 15x = 120 - 20
30x = 100
x = 10/3
Substitute x = 10/3 in y = 8 - 3x:
y = 8 - 3 (10/3)
y = 8 - 10
y = -2
Hence, the solution to the system of equations is (10/3, -2).
