Katelyn wants to build a desk for her doll. Her actual desk is 3 feet tall. The scale is 0.5 in: 1 ft How tall will the doll des

velikii [3]

Each foot of the real desk will be 0.5 on the dolls desk.
3ft x 0.5 in per ft = 1.5 inches

Recall the experiment comparing patients 4 weeks after surgery for carpal

dimulka [17.4K]

Answer:

4. H0: u1= u2 Ha; u1≠ u2

5. The smaller value of p supports the null hypothesis.

Step-by-step explanation:

4. The null and alternate hypotheses are

H0: u1= u2 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1≠ u2 i.e there a difference between the mean pinch strengthof the two surgeries

It can be written like this as well

H0: u1 -u2= 0 i.e there no difference between the mean pinch strengthof the two surgeries

against the claim

Ha; u1 -u2≠ 0 i.e there a difference between the mean pinch strengthof the two surgeries

Part 5. The test having a p- value less than 0.05 tells that the null hypothesis cannot be rejected. Theres no evidence to reject the null hypothesis.

The smaller value of p supports the null hypothesis.

Help needed on this composition math problem

Marrrta [24]

Given that f(x) = x/(x - 3) and g(x) = 1/x and the application of function operators, f ° g (x) = 1/(1 - 3 · x) and the domain of the resulting function is any real number except x = 1/3.

<h3>How to analyze a composed function</h3>

Let be f and g functions. Composition is a binary function operation where the variable of the former function (f) is substituted by the latter function (g). If we know that f(x) = x/(x - 3) and g(x) = 1/x, then the composed function is:

$f\,\circ\,g \,(x) = \frac{\frac{1}{x} }{\frac{1}{x}-3}$

$f\,\circ\,g\,(x) = \frac{\frac{1}{x} }{\frac{1-3\cdot x}{x} }$

$f\,\circ\,g\,(x) = \frac{1}{1-3\cdot x}$

The domain of the function is the set of x-values such that f ° g (x) exists. In the case of rational functions of the form p(x)/q(x), the domain is the set of x-values such that q(x) ≠ 0. Thus, the domain of f ° g (x) is $\mathbb{R} - \{\frac{1}{3} \}$ .

If A = {2, 3, 4, 5} and B = {5, 6, 7, 8}, what is A U B? {2, 3, 4, 5, 6, 7, 8) {5}

Ulleksa [173]

Hey!!!!

Here's your answer:

Solution:

A={2,3,4,5}

B={5,6,7,8}

 A U B={2,3,4,5} U {5,6,7,8}

 ={2,3,4,5,6,7,8}

In case of Union,we have to list all the elements which are present in both sets.

Hope it helps...

Good luck on your assignment

Stereo has a list price of $150 but is on sale for 20% off the list price what is the sale price of the stereo???

8_murik_8 [283]

Answer:

The correct answer is option A.120

Step-by-step explanation:

Let's start by analyzing the information they have given us.

We know that the stereo has a list price of $ 150, but at the time of payment, we are told that it has a 20% discount.

Now we must find out what the discount was applied to know the final price of the stereo.

One way to calculate the percentage would be multiplying 150 by 0.20

150.0.20 = 30

The discount applied is $ 30, so now we just have to subtract that amount from the original price:

150-30 = 120

Therefore, the correct answer is option A.
