Answer:
5
Step-by-step explanation:
2/4=y/10
=> 2x10=yx4
=> 20=yx4
=>y=5
Answer:
2391 and 5016
Step-by-step explanation:
Answer:
Consider the following explanation
Step-by-step explanation:
The experimental unit here is a cat.
The explanatory variable is a numerical variable which identifies the time for which a given cat is subjected to hunger deprivation.
The response variable is a categorical variable which identifies whether there is an increase in aggression in a given cat.
The interacting variable is a numerical variable where weight of a given cat is noted.
Population here is the 10 cats.
There is no control group for the given experiment.
Dependent variable is the weight of each cat as it changes as the experimental units are subjected to hunger deprivation.
The given quadratic equation has no real solutions.
Given quadratic equation is:
<h3>What does the discriminant of a quadratic equation tell?</h3>
The discriminant(D) of a quadratic equation tells about the nature of roots.
If 
, the roots of the quadratic equation will be real and distinct.
If 
, the roots of the quadratic equation will be real and equal.
If 
, the roots of the quadratic equation will be imaginary.
Given that the quadratic has a discriminant value of -16.
So, the roots of the given quadratic equation will be imaginary.
So, the given quadratic equation has zero real solutions.
Hence, the given quadratic equation has no real solutions.

Answer:
-7/3
Step-by-step explanation:
When finding slope from a graph, I always look for places where the graph crosses grid intersections. One of these is the y-intercept, (0, 40).
You have to go quite some distance to find another. It looks to me like the next grid crossing is at (30, -30). At this point, you can do either of two things:
- find the ratio of grid squares
- use the slope formula
What you want to calculate is the ratio of the change in vertical height (rise) to the change in horizontal distance (run). If you use grid squares, you need to make sure the grid has the same number of units horizontally as vertically. (Here a grid square is 10 units in each direction, so we're OK on that point.)
We have observed that the line falls 7 grid squares vertically for a change of 3 grid squares to the right. So, the slope using grid squares is ...
m = rise/run = -7/3
Using the slope formula, we calculate the slope to be ...
m = (y2 -y1)/(x2 -x1)
m = (-30 -40)/(30 -0) = -70/30 = -7/3
The slope of the line is -7/3.
