Write the null and alternative hypothesis which would pertain to a hypothesis test described in each scenario last year politicians average 2000 trouble hours this year with an election occurring it is expected that they will travel more hours

Answers

Answer 1

Considering the situation given, it is found that:

The null hypothesis is [tex]H_0: \mu = 2000[/tex]The alternative hypothesis is: [tex]H_1: \mu > 2000[/tex].

At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:

[tex]H_0: \mu = 2000[/tex]

At the alternative hypothesis, we test if this amount has increased, that is:

[tex]H_1: \mu > 2000[/tex]

What is a inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Now, replacing m by 8 in the given inequality, we get

5 ≤ 4

Therefore, the given statement is false.

There are two solutions for x;

x = 0

x = [tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

Answer:

x = 0 or -3/2

Step-by-step explanation:

( 2 x +  3 ) ^2  −  6 x −  9  =  0 ---> distribute

4x^2 + 6x + 6x + 9 - 6x - 9 = 0 --> add the 9's together

4x^2 + 12x  - 6x = 0 --> combine like terms

4x^2 + 6x = 0 --> common factor

2(2x^2 + 3x) = 0 --> divide by 2 on both sides

2x^2 + 3x = 0

then you should use the quadratic formula (can't add here or the explanation would take too long)

What is the value of x in the equation 3(2x + 8) = 0? (4 points) Group of answer choices −8 −4 4 8

Answers

Answer:

-4

Step-by-step explanation:

Start with 3(2x + 8) = 0.

Distribute the 3 to the 2x and 8 in the parentheses.

That will give you 6x + 24 = 0.

Subtract 24 from both sides, which will get x by itself and leave you with 6x = -24.

Divide both sides by 6 to get x = -4.

That is your answer.

Hope this helped.

3(2x + 8)= 0
3(2x) = 6x
3(8) = 24
6x + 24 = 0
24-24
0-24
6x = -24
-24/6
X = -4

Hey guys, our adviser showed us an example on how to solve the problem that is given in our module. Unfortunately, there's a part of the given example that I can't recall. So, can you explain how to get the answer? (picture above)​

Answers

Given :

45x[ 4/9 = 1/5 + 1/x ]

To Do :-

To multiply 45x to all the terms .

Solution :-

Given that ,

45x[ 4/9 = 1/5 + 1/x ]

Distributive property of Multiplication over addition ,

a( b + c ) = ab + ac

So that ,

45x * 4/9 = 45x* 1/5 + 45 x * 1/x 5x * 4 = 9x + 45 20x = 9x + 45

Step-by-step explanation:

As it says, multiply 45x to all the terms. This is required to get rid of fractions.

See the steps below:

45x [ 4/9 = 1/5 + 1/x]45x(4/9) = 45x(1/5) + 45x(1/x)    ⇒ multiply5x(4) = 9x + 45                          ⇒ simplify20x = 9x + 45                            ⇒ end result without fractions

subtract the 4 from one side

[tex] - 2y = - 2x - 4[/tex]

divide the -2 from the y and the-2x and 4

[tex]y = - x + 2[/tex]

-y + 6 = x

subtract the 6 and add -6 after the x

6x - y - 3 = 0

add the y so it cancels out
