The slope-intercept is the first option, y=-3x-6
Answer:
ax2 + bx + c = 0.
Step-by-step explanation:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero.
Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Answer:
Skewed
Step-by-step explanation:
Looking at the options;
- Bimodal has to do with 2 modes in a symmetrical Distribution. Thus is doesn't apply to the mean.
-bell shaped deals with the graphical depiction of a normal probability distribution, whereby the underlying standard deviations from the mean will create the curved bell shape. So it is not used for mean.
- symmetric deals mirror images of the distribution when a vertical line is drawn down the middle of the distribution.
-skewed shape tells us whether the mean is pulled to the tail and if it is more than or less than the median.
- uniform shape means same frequency for each class.
The answer is 83x hope this helps
Let, Number of multiple choice = x
Number of short answer question = y
Now, x + y = 20
& 3x + 11y = 100
Multiply 1st equation by 3, and subtract from eq,2,
3x + 3y = 60
After subtraction,
8y = 40
y = 40/8
y = 5
Now, substitute in eq (1),
x + 5 = 20
x = 15
In short, There are 15 Multiple choice & 5 short answer questions
Hope this helps!
