Answer:
9. n=-15 , 10. f=6, sorry i can't help you more I am just tired and have to get some rest but i hope this helps
Step-by-step explanation:
9. Eight less than 1/3 a number n is -13
so -13 = 1/3n -8
then
-5 = 1/3n
multiply 3 to each side
-15 = n
10. a number f multiplied by -12.3 is -73.8
so -12.3f= -73.8
divide -12.3 on each side
so f=6
<span>Discriminant is 28 (c)
First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation)..
By subtracting 10x both sides (to get it on the other side)..
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 10x - 10x
9x^2 - 10x + 2 = 0
Now the discriminant is: b^2 - 4ac
The quadratic equation is Ax^2 + Bx + C = 0
Here, A = 9, B = -10 and C = 2
(-10)^2 - 4 (9)(2)
= 100 - 4 (18)
= 100 - 72
= 28</span>
Answer:8 5/12 - 8 3/4

Answer:
Box and Whisker Plot
Step-by-step explanation:
Box and Whisker Plot is a visual display of a data set in statistics used to display a 5-number summary. The five number summary is the minimum value, the maximum value, the median, the upper quartile, and the lower quartile.
For the box plot a box is drawn from the first quartile to the third quartile with a vertical line going through the box at the median. Also, the whiskers go from each quartile to the minimum or maximum.
