Solve the equation negative 3X +9 equals three(2x+3) + 3(x-4) + 1
timofeeve [1]

Answer:

1

Step-by-step explanation:

-3x+9=3(2x+3)+3(x-4)+1

Distributive property in the parenthesis

Combine Like Terms

-3x+9=9x-2

Get the x’s on one side

1.) What is a qualitative prediction? * and 2.) What is a quantitative prediction? * THERE IS A PIC THAT COME WITH QUESTION PLEA
frozen [14]
I believe a qualitative prediction requires a prediction with out any numerical data to support it while a quantitative predictions require a prediction supported by numerical data.

A real world example of this is in chemistry during a lab.  qualitative data is based off of observation with out numerical data such as a color change.  quantitative data is based off of observation with numerical data such as the mass changes.

(quantitative prediction is decision from data based on percentages, probabilities, and so on while qualitative predictions are based off of given information).
I hope this helps and let me know if you need further explaining.

Ulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.
kiruha [24]

Answer:

7/ 36

Step-by-step explanation:

Roll of 2 fair six sided die :

Sample space = 6² = 36

Sum of 7:

(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6

Probability = required outcome / Total possible outcomes

Required outcome = 7

Total possible outcomes = 36

P(obtaining a sum of 7) = 7 / 36
