5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following
goblinko [34]

Answer:

<em>H</em>₀: <em>µ</em> = 1100 vs. <em>Hₐ</em>: <em>µ</em> ≠ 1100.

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.

Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.

The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.

It is also known as the research hypothesis and is denoted by Hₐ.

In this case the hypothesis can be defined as follows:

Null hypothesis:

<em>H</em>₀: The average calorie intake of a diner at this restaurant is 1100, i.e. <em>µ</em> = 1100.

Alternate hypothesis:

<em>Hₐ</em>: The average calorie intake of a diner at this restaurant is different from 1100, i.e. <em>µ</em> ≠ 1100.

Help me please!!! I really need it!

<u>Answer:</u> The value of x can be either 5 or 10.

<u>Step-by-step explanation:</u>

We are given:

Total profit, P = $5600

The given equation follows:

⇒ P = 600 + 1500x - 100x²

Putting value of P in above equation, we get:

⇒ -100x² + 1500x + 600 = 5600

⇒ -100x² + 1500x - 5000 = 0

⇒ 100x² - 1500x + 5000 = 0

Solving this equation by middle term split, we get:

⇒ 100(x² - 15x + 50) = 0

⇒ (x² - 10x - 5x + 50) = 0

⇒ x(x - 10) - 5(x -10) = 0

⇒ (x - 10)(x - 5) = 0

⇒ x = 10, 5

Hence, the value of x can be either 5 or 10.

Solve system of equations for x + y: 3x + 2y = -18 &amp; 2x + 9y =-12
blondinia [14]

Answer:

(- 6, 0 )

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 18 → (1)

2x + 9y = - 12 → (2)

Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is

6x + 4y = - 36 → (3)

- 6x - 27y = 36 → (4)

Add (3) and (4) term by term to eliminate x

- 23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and evaluate for x

Substituting into (1)

3x + 0 = - 18

3x = - 18 ( divide both sides by 3 )

x = - 6

Solution is (- 6, 0 )

For the school concert band performance student tickets cost eight dollars each and adult tickets cost $12 each the seller is co
Alexxandr [17]
S + a = 300...s = 300 - a
8s + 12a = 3200

8(300 - a) + 12a = 3200
2400 - 8a + 12a = 3200
-8a + 12a = 3200 - 2400
4a = 800
a = 800/4
a = 200 <==== 200 adult tickets

s = 300 - a
s = 300 - 200
s = 100 <=== 100 student tickets
