Answer: 10th Percentile
Step-by-step explanation:
The percentile of a variable in a dataset is the percentage position of the variable in the dataset such that the variables before this variable are below this percentage.
There are 20 variables in this data set and Biff scored a 65 which occupies the second and third positions on this dataset.
Picking the first position, 65 is the second variable in the data set so Biff's percentile is;
= Position on dataset/ No. of variables in data set
= 2/20
= 10%
= 10th percentile
Answer:
3 terms
Step-by-step explanation:
Each of the following is a term:
13·8, or 5.
-5·2, or -10
(6/3), or +2
And so the value of the entire expression is 104 - 10 + 2, or 94 + 2 = 96
The specific answer to this question is : "this expression has three terms."
Answer:
m = 3, c = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x , or y = 3x + 0 ← is in slope- intercept form
with m = 3 and c = 0
Answer:
2310789600
Step-by-step explanation:
10 digits + 26 letters = 36

Hope this helps, although i am not 100 percent sure its right.
Answer:
2x^2 = 6x - 5.
-x^2 - 10x = 34.
These have only complex roots/
Step-by-step explanation:
3x^2 - 5x = -8
3x^2 - 5x + 8 = 0
There are complex roots if the discriminant 9b^2 - 4ac) is negative.
Here the discriminant D = (-5)^2 - 4*-5*8 = 25 + 160
This is positive so the roots are real.
2x^2 = 6x - 5
2x^2 - 6x + 5 = 0
D = (-6)^2 - 4*2*5 = 36 - 40 = -4
So this has no real roots only complex ones.
12x = 9x^2 + 4
9x^2 - 12x + 4 = 0
D = (-12)^2 - 4*9 * 4 = 144 - 144 = 0.
- Real roots.
-x^2 - 10x = 34
x^2 + 10x + 34 = 0
D = (10)^2 - 4*1*34 = 100 - 136 = -36.
No real roots = only complex roots.
