You should definitely talk to your teacher about it, as well as check out Khan Academy online for detailed explanations and videos of the subject you're working on.

Tough question to answer in just a few words.  For starters:

1) Read assigned portions of your textbook several times; outline what you are reading

2) Make a list of questions about material you don't understand; get help (here or from your teacher) with that material. 

3) Read your textbook or other learning material BEFORE you attend class so that you'll have some familiarity with the vocabulary and subject matter.  Going to class without having prepared in this way almost guarantees that you won't understand very much.

Plenty more.  If you want further dialogue, ask some questions and I'll try to respond with something helpful.

An automobile manufacturer is concerned about a possible recall of its best-selling four-door sedan. If there were a recall, the

Answer:

0.27

Step-by-step explanation:

Suppose A is the event of defect in the brake system and B is the event of defect in the fuel system,

We have given,

P(A) = 0.25,

P(B) = 0.17

P(A∩B) = 0.15 ( the probability of defects in both systems simultaneously is 0.15 ),

We know that,

P(A∪B) = P(A) + P(B) - P(A∩B)

= 0.25 + 0.17 - 0.15

= 0.27

Hence, the probability that the defect is the brakes or the fueling system is 0.27.

Which of the following shows the length of the third side, in inches, of the triangle below? (1 point)
GrogVix [38]

Answer:

2, sqrt of 7633

Step-by-step explanation:

for now, we'll leave the 3rd side as x

y using the Pythagorean theorem, we can conclude that (1) 48^2+x^2=73^2 or (2) 48^2+73^2=x^2.

1. If we conclude the x isn't the longest, the x would be 3025 which is the sqrt of 55, now is invalid because the 2 smallest sides can't be more than the longest side when they add up 55+48>73 so that is invalid

2. Then, it leaves us with only 1 choice left! concluding that the 3rd side is the longest. Which the answer is sqrt of 7633

Answer: The first.

Step-by-step explanation: If you draw out a triangle and lable the points on each point with values from each triangle, you get J=M, K=N, and L=O. The first is the only one that proves it.
