Answer: The number of air conditioners sold per day in a city and the daily temperature
Step-by-step explanation:
We know that if there is a causal relationship between two variables then one variable is responsible for causing the other variable.
- the number of hats sold and the number of mittens sold in a city.
there is no causal relationship between the variables since both are independent variables.
- the amount of butter and the amount of bread consumed by a family
.
there is no causal relationship between the variables since both are independent variables.
- the number of notebooks sold and the number of pens sold in a stationery store
.
there is no causal relationship between the variables since both are independent variables.
- the number of air conditioners sold per day in a city and the daily temperature
.
there can be causal relationship between the variables since by increasing or decreasing temperature the the number of air conditioners sold per day in a city can be increased or decreased respectively.
- the number of hours a person can swim and the depth of the pool.
there is no causal relationship between the variables since both are independent variables.
Answer:
| a - b | < length of third side < a + b
Step-by-step explanation:
Visualize the two given sides of the triangle (let's call then a and b), joined at the vertex of the triangle, and forming an angle. We can join the other free end of these two segments, with another segment whose length would vary according to how tiny or large the angle is. We can spread the aperture of the angle they form as much as we can just below (not reaching this angle measure, because in such case, there will be no triangle of tangible area. In such case, the length of the joining segment will be limited by the addition of the two sides:
length of third side < a + b
In the case the aperture of the angle formed by the two given sides is diminished as much as possible to still form a measurable triangle, the angle has to be just larger than zero, and in such case, the segment joining the other to ends of a and b would be just larger than the absolute value of the difference between a and b:
length third side > | a - b|
These are the two extreme cases, and the length of the third side must be within these limits.
Simplify the following:
x/((x - 2) (x + 9) (3 x - 6))
Factor 3 out of 3 x - 6:
x/(3 (x - 2) (x - 2) (x + 9))
Combine powers. x/((x - 2) (x + 9)×3 (x - 2)) = (x (x - 2)^(-1 - 1))/((x + 9)×3):
(x (x - 2)^(-1 - 1))/(3 (x + 9))
-1 - 1 = -2:
Answer: (x (x - 2)^(-2))/(3 (x + 9))
Answer:
Vertex is (-1/3, -13/3)
Axis of symmetry is x = -1/3
Step-by-step explanation:
For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k
Vertex form for this equation is:
Y = -6(x + 1/3)^3 - 13/3
To find the vertex, the formula is (h,k)
So, ( -1/3, -13/3)
Answer:19
Step-by-step explanation:
Because there is 5 stripped shirts +8 solid shirts +6 polka dot shirts=19 shirts in total.
