Answer:
Option B)
Step-by-step explanation:
We are given the following in the question:
Hypothesis:
The doctors and u=instructor claims that practicing yoga reduces blood pressure and hence is beneficial to people.
Population mean, μ = 140 mm
Sample mean, 
= 139 mm
Sample size, n = 51
Sample standard deviation, s = 5 mm
Thus, we can design the null hypothesis and alternate hypothesis as
The null hypothesis states that the population have a blood pressure of 140 mm. The alternate hypothesis states that yoga reduces the blood pressure and the sample has a blood pressure less than 140 mm.
Thus, the correct answer is
Option B)
Answer: A and c
Step-by-step explanation: because they are the only ones that have p,x,m and not just seperate.
Answer:
regular pentadecagon
Step-by-step explanation:
it has 15 sides
that is what matches the exterior angled sum property - 360degree
let me explain it
1 side = 180 - 156 = 24
360/24 = 15
mark me brainliest and thank me if you like the answer
Answer:
x+4
Step-by-step explanation:
What I like to do in these types of problems is to separate the terms with a variable and those without.
So move +4 to the very end of the problem to make it look like this:
6x-3x-2x+4
Now simply subtract! After subtracting the first two terms (6x and -3x) it should look like this:
3x-2x+4
Then subtract once more (3x-2x)!
x+4
This cannot be simplified anymore so x+4 should be your final answer!
