Answer:
The null hypothesis is: 
The alternative hypothesis is: 
Step-by-step explanation:
At the null hypothesis, we test if the mean is equal to a certain value.
At the alternate hypothesis, we test if the mean is less than, more than, or different from the value tested at the null hypothesis.
The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of 20 lb.
This means that the null hypothesis is:
Could it be that the average tuft strength is above 100 lb?
The world above means that the appropriate alternative hypothesis is:
H = Tower Height = 320
W = Tower Width = 260
h = Model Height
w = Model Width
h = (1/500) * H = (1/500) * 320 = .64 feet
w = (1/500) * W = (1/500) * 260 = .52 feet
Now, we need to convert these measurements to inches.
There are 12 inches per foot.
Let x = height in inches and y = width in inches
The ratio below compares feet to inches
x / h = 12 in / 1 ft
y / w = 12 in / 1 ft
Plug in h and w, cross multiply, and solve for x and y, respectively.
x / .64 = 12 / 1
1 * x = .64 * 12
x = 7.68 in
y / .52 = 12 in / 1 ft
1 * y = .52 * 12
y = 6.24 in
Answer:
The sum of the two leg measures equals the hypotenuse.
Step-by-step explanation:
The answer choice "The measure of the hypotenuse squared is equal to the sum of the side measures squared" is true because it is the Pythagorean Theorem.
The other two answer choices basically describe what a hypotenuse is.
Answer: 600 Miles
Step-by-step explanation:
We start off with $300.
We have to spend $60 to rent the car.
300 - 60 = $240
The remaining $240 can be spent on miles.
$240/0.40 = 600 Miles
