Answer:
which p? there isn't any p in above equation
In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.
Let the other side is of length b inches .
Now we use pythagorean identity, which is
Here, a = 12 and c=18
Substituting these values, we will get
And the formula of perimeter is
Substituting the values of the two legs, we will get
Answer:
a. True
Step-by-step explanation:
By ∝= 5% we mean that there are about 5 chances in 100 of incorrectly rejecting a true null hypothesis. To put it in another way , we say that we are 95% confident in making the correct decision.
In the given question the null hypothesis is
H0: u ≤ 1 hour and Ha: u > 1 hour
So there is a 5% chance that the erroneous conclusion will be made that students spend on average more than 1 hour per assignment.
The given statement is true.
B is one of them, i'm not sure how any of the other answers are equivalent to 20% of 45 which is 8.
Sum of all angles in a 62 sided polygon = 10800°. (Mark me as brainliest pls!)
