Answer:
24/225
Simplified: 8/75
Step-by-step explanation:
8 + 4 + 3 = 15
Since there are no replacements the denominator will get lower every time a marble is pulled.
First is blue which means,
3/15
The second is white,
8/15
If I'm not wrong you would multiply 3/15 and 8/15 and you get 24/225.
Simplified: 8/75
Answer:
The speed of sound is 
Step-by-step explanation:
Let
x-----> the speed of sound
we know that

so

solve for x

- Quadratic Formula:
, with a = x^2 coefficient, b = x coefficient, and c = constant.
Firstly, using our equation plug in the values into our equation (a = 1, b = -4, and c = 3):

Next, solve the exponent and multiplications:

Next, solve the subtraction:

Next, solve the square root:

Next, you are going to solve this equation twice - once with the + symbol, once with the - symbol as such:

<u>Your zeros (x-intercepts) are 3 and 1. These solutions are real and rational.</u>
The arithmetic mean provides a single measure for a certain population, also called the average.
The sum of a set of numbers divided by the total number of numbers in the set is known as the arithmetic mean or arithmetic average in mathematics and statistics.
The ratio of the total number of observations divided by the sum of all the given observations is known as the arithmetic mean. For instance, if the data set contains 5 observations, it is possible to get the arithmetic mean by adding all 5 of the given observations and dividing by 5.
