Answer:
The correct option is
Step-by-step explanation:
From the question we told that
The test statistics is 
The number of student is n = 5
The degree of freedom can be mathematically evaluated as
=> 
The p-value is mathematically evaluated as
using the z table(shown in second and third image ) we obtain that
A) 3 times 7x makes it a normal number of 21.
B) using PEMDAS you must multiply 5 times 5 to put 5 to its own power, then multiply by 2 to get 50, then add 4 getting 54.
C) 9 times 5y gets the normal number of 45, then subtract that from 80, you get 35.
Okay so we know that 3/5 of the conductors club went on the last camping trip. We also know that 3/5 of the club is equal to 39 people. All we have to do is find the last 2/5 and add it to our 3/5 to get the answer:
To find how much each 1/5 is, divide 39 by 3. This will give us 13. Then we multiply it by 5, because there are five parts. This gives us 65. So the answer is 65
Actually Welcome to the Concept of the Inverse Trigonometry Function.
So here, we get as
SinX = 1/2
X = Sin^-1(1/2)
X= 30°
1) you have to find the difference between pipe A and pipe B, which is 6.40.
23.55-17.15=6.40
2) after finding the difference. You will take that difference and put it out of 23.55 and multiply by 100 to get your percentage. As so:
(6.40/23.55)(100)= 27.176% which rounds to 27% as a whole number.
Your answer is 27%. Hope that helps!
