Answer:

Theorem are the type of statement must be proven in geometry.

Step-by-step explanation:

1) Axiom are the statements or prepositions that are accepted and do not need any proof. Example : if a and b are real numbers then then their sum is also a real number.

2) Definition is a statement given to define something.

3) Postulates is a proposition that requires no proof and is for a specific purpose assumed true, and that is used in the proof of other propositions; axiom.

4) theorem are the statements that can be proved using axioms , definition etc.

Thus, from above all theorem are the type of statement must be proven in geometry.

anastassius [24]

Step-by-step explanation:

$1.80 per pound

The amount she's supposed to buy it is

1.80 × 12.5 = $22.5

She paid $21.25 for the 12.5 pounds, that means she saved

$22.5 - $21.25 = $1.25

the amount she saved per pound is

1.25/12.5 = $0.1 per pound

Of the 400 eighth-graders at pascal middle school, 117 take algebra, 109 take advanced computer, and 114 take industrial technol

Hatshy [7]

If 164 of the 400 eighth-graders take none of these courses, then 400-164=236 students take some courses.

Let x students take all three courses, then:

1. 70-x take only both algebra and advanced computer,

2. 34-x take only both algebra and industrial technology,

3. 29-x take only both advanced computer and industrial technology.

Now let's count how many student take only one course:

1. 117-(x+34-x+70-x)=13+x take algebra,

2. 109-(x+29-x+70-x)=10+x take advanced computer,

3. 114-(x+29-x+34-x)=51+x take industrial technology.

Now count all students that take some courses:

51+x+10+x+13+x+29-x+34-x+70-x+x=236,

x=236-51-10-13-29-34-70,

x=29.

Answer: all three courses take 29 students.

Consider the midterm and final for a statistics class. Suppose 13% of students earned an A on the midterm. Of those students who

padilas [110]

Answer:

There is a 38.97% probability that this student earned an A on the midterm.

Step-by-step explanation:

The first step is that we have to find the percentage of students who got an A on the final exam.

Suppose 13% students earned an A on the midterm. Of those students who earned an A on the midterm, 47% received an A on the final, and 11% of the students who earned lower than an A on the midterm received an A on the final.

This means that

Of the 13% of students who earned an A on the midterm, 47% received an A on the final. Also, of the 87% who did not earn an A on the midterm, 11% received an A on the final.

So, the percentage of students who got an A on the final exam is

$P_{A} = 0.13(0.47) + 0.87(0.11) = 0.1568$

To find the probability that this student earned an A on the final test also earned on the midterm, we divide the percentage of students who got an A on both tests by the percentage of students who got an A on the final test.

The percentage of students who got an A on both tests is:

$P_{AA} = 0.13(0.47) = 0.0611$

The probability that the student also earned an A on the midterm is

$P = \frac{P_{AA}}{P_{A}} = \frac{0.0611}{0.1568} = 0.3897$

There is a 38.97% probability that this student earned an A on the midterm.
