Perimeter of a triangle = all 3 sides added together
x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==
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:
