Answer:
no it is not true there is still a 50% chance it will be tails
Step-by-step explanation:
So here is the solution of the given problem above.
To find the area we are just going to use this formula. A = L x W.
Let x be the width and 2x is the length. Given that the area is 8 square meters. So let us find x first.
Plug in the values:
8 = (2x)(x)
8 = 2x^2 << divide both sides by 2 and we get
4 = x^2
Then square 4 and x^ 2 and we got
2 = x
Therefore, the width of the room is 2 meters and the length 2x is 4 meters. Hope this is the answer that you are looking for.
Answer:
The required hypothesis to test is and .
Step-by-step explanation:
Consider the provided information.
It is given that the nightclub has recently surveyed a random sample of n = 250 customers of the club.
She would now like to determine whether or not the mean age of her customers is over 30.
Null hypotheses is represents as . Thus the null hypotheses is shown as:
The alternative hypotheses is represents as . Thus the alternative hypotheses is shown as:
Hence, the required hypothesis to test is and .
Answer:
x= 11.616043
Simplifies to:
3.162278x−7=2.645751x−1
Step 1: Subtract 2.645751x from both sides.
Step 2: Add 7 to both sides.
Step 3: Divide both sides by 0.516527.
