What is 4/6 x 6 as a mixed number?

Answers

Answer:

Step-by-step explanation:

4/6 x 6 can be thought of as 4/6 x 6/1.

When multiplying two fractions, multiply the numerator (top number) with the numerator and the denominator (bottom number) with the denominator.

So we have: (4x6) / (6x1)

Which can be simplified to: 24/6, or 4.

Solve the system of equations.
- 5y + 8x = -18
5y + 2x = 58
х=
y =

Answers

Answer:

x = 4 and y = 10

Step-by-step explanation:

-5y + 8x = -18

5y + 2x = 58

First you will want to get rid of y from both equations, so you add both equations together.

You will get 10x = 40, then subtract 10 from both sides and you get x = 4.

Now substitute x as 4 in any of the equations to get y.

-5y + 32 = -18

-5y = -50

y= 10

Answer:

x = 4

y = 10

The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive

A. Continuous data example would be the distance between two cities, which may take on any value along a continuous scale.

C. Another example of continuous data is sumo wrestler weights, which can take on any value along a continuous scale.

D. Another example of continuous data is movie duration, which can have any value along a continuous scale.

B. An example of discrete data is the number of siblings each student in a class has. The only possible values for discrete data are generally integers. The number of siblings a student has in this situation can only be a whole number, making it discrete data.
