Answer:
Explained
Step-by-step explanation:
Null hypothesis is something that states that there is no difference between the population means, while the alternative hypothesis states that there is difference between the two.
So, If the difference of the sample means is 10cm, and the standard deviation of the difference of sample means is 6 cm. Then the population means of the two districts will be different according to the manual solution.
Answer:
The population means of the two districts are different.
Step-by-step explanation:
x = y + 3
A) x = (7 – x) + 3
B) x – (y + 3) = 7
C) (y + 3) – y = 7
D) x – y = y + 3

Answer:
A Function states an equation that has only one answer for y for every x. Also, a function assigns exactly one output to each input of a specified type.
i,e y= f(x) where x represents the input variable and y represents the output value.
Given the function:
Substitute the given input value of x =2 , we get;
or
Simplify:
Therefore, the function for x=2, we have F(2) =8.
