Answer is:
B

Answers

Answer 1

Answer:

[tex]H_{0} = 0.5[/tex]

[tex]H_{a} > 0.5[/tex]

Option b

Step-by-step explanation:

Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election.

The null hypothesis is always an equalityu related to the expected, or tested value. In this question, the tested value is half of the students, a proportion of 0.5, that is: [tex]H_{0} = 0.5[/tex]

The alternate hypothesis is related to the test we are taking. In this question, we are testing if the majority of the students plan to vote, that is, if the proportion of the students that plan to vote is higher than 0.5. So [tex]H_{a} > 0.5[/tex]

So the correct answer is given by option B.

Elis, Raine and Avery buy a boat for $33 000.
Elise pays $12 000, Raine pays $6000 and Avery pays the rest.
Six years later they sell the boat for $25 300.
They share the money in the same ration that they bought the boat.
How much money does Avery lose on the sale of the boat?

Answers

Amount Avery paid: 32,000-12,000-6,000 = 15,000

Divide portion she paid by total cost:

15,000/33,000

Simplify to 15/33

Multiply the amount the boat was sold for by her portion:

25,300 x 15/33 = 11,500

Subtract the amount she got from the amount she paid:

15,000 - 11,500 = 3,500

She lost $3,500

Answer:

yes

Step-by-step explanation:

yes!

Answers

Answer:

14 one fourths

Step-by-step explanation:

First, we convert 7/2 into a fraction with the denominator of a four. To do this, we multiply the top and bottom by 2. 7*2 is 14, and 2*2 is 4, which gives us 14/4. This means that there are 14 one fourths in 7/2. Hope this helps!

Answer:

14 fourths

Step-by-step explanation:

Hey There!

So to solve this problem we need to divide 7/2 by 1/4

[tex]\frac{7}{2}divided by\frac{1}{4} =14[/tex]

Therefore 14 fourths can go into 7/2
