Answer:
a. Cat is the least popular.
b. It represents 8.
c. 6 people preferred giraffes than dogs.
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.
For clearly look we can seperate the number parts and the letter parts because they are all “*” and “/“ caculation
Initial fraction: (20 * a^2 * b) / ( 5 * a * b^2) = (20 / 5) * (a^2 / a) * (b / b^2)
Result: (4*a) / (b) = (4*a) / (1*b) = (4/1) * (a/b)
As you can see the result is a fully simplifying form so just simplify any thing you can from initial fraction
20/5 = 4/1 (both nume and deno are divided by 5)
a^2 / a = a/1 (divided by a)
b / b^2 = 1/b (divided by b)
Multiply all above we get the result 4a/b (just for checking whether we did right or not)
Next, multiply all that we have divided in previous step: 5*a*b = 5ab
=> problem solved
Answer:
i think its independant , not independant , not indepedant i think im not sure
Step-by-step explanation:
We know that
the formula in solving residual is shown below:
[Residual value] = [Observed value] - [predicted value]
so
[Observed value]=25
[predicted value]=27.745
[Residual value]= 25 - 27.255----------> -2.745
Residual values = -2.745
the answer is the option D) -2.745
