What two numbers add to 10 and multiply to -192? How do you find it?

Levart [38]

There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative.
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum.
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this.

The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.

Min: 2 Q1: 7.5 Med: 11 Q3:14 Max:17

Step-by-step explanation:

Min is the minimum value of the provided data. In this case it is easier to tell because the numbers are arranged in ascending order;

The minimum value is;

= 2

Quartile 1 is the value that divides into half, the first half of the provides values. The first half of the value is divided by the median (In this case 11). The value that is halfway the values before median value is the Q1

In this case, we end up with two values because the numbers of values are even;

6 & 9

We sum the two and divide by 2

(6 + 9) / 2 = 7.5

Median is the value that is in the middle of all the provided values arranged in ascending order. Because the values are even, we end up with two numbers;

11 & 11

Again we sum the two and divide by 2;

(11 + 11) / 2 = 11

Quartile 3 is the value that divides into half, the second half of the provided values. This means the value three-quaters way. Because the number of provides values is even, then we end up with two values;

14 & 14

We sum the two and divide by 2

(14 + 14) / 2 = 14

Max value is the largest number of all the values;

= 17
