Answer:
400
Step-by-step explanation:
325 + 75
Answer:
Options 1) and 3) are correct.
Step-by-step explanation:
R={(A,B)|A⊆B}
Reflexive:
As A⊆A,
∈ R.
So, R is reflexive
Symmetric:
Let
∈ R. So, A⊆B
Take ![A=\{1,2\}\,,\,B=\{1,2,3,4\}](https://tex.z-dn.net/?f=A%3D%5C%7B1%2C2%5C%7D%5C%2C%2C%5C%2CB%3D%5C%7B1%2C2%2C3%2C4%5C%7D)
Here, A⊆B but B⊄A
So,
∉ R
R is not symmetric
Transitive:
Let
∈ R and
∈ R
So, A⊆B and B⊆C.
Therefore, A⊆C
So,
∈ R
Hence, R is transitive.
Option 1) is correct.
Antisymmetric:
Let (A,B)∈R and (B,A)∈R
So, A⊆B and B⊆A
Hence, A = B
So, R is antisymmetric
Option 3) is also correct.
Answer:
9 mile/ 1 hour
Step-by-step explanation:
Because the squirrel ran 9 miles in 1 hour, so u have to divide 9 miles by 1 hour.
Answer: We reject the null hypothesis.
Step-by-step explanation:
Given : Significance level : ![\alpha=0.01](https://tex.z-dn.net/?f=%5Calpha%3D0.01)
Let p represents the proportion of the settled medical malpractice suits.
Given claim : The percentage of settled medical malpractice suits is at least 50%.
i.e. ![p\geq 0.5](https://tex.z-dn.net/?f=p%5Cgeq%200.5)
Thus,
![H_0:p\geq0.5\\\\H_a:p](https://tex.z-dn.net/?f=H_0%3Ap%5Cgeq0.5%5C%5C%5C%5CH_a%3Ap%3C0.5)
We know that when the calculated p-value is less than the significance level (
) then we reject the null hypothesis, if p-value is greater than the significance level (
) then we do not reject.
Now , the calculated value 0.012 is less than the 0.01, so we reject the null hypothesis.
