NEED HELP PLZ

Mathematics
1 answer:
Angelina_Jolie [31]3 years ago

Answer:

0.14

Step-by-step explanation:

From the question given above, the following data were obtained:

Grade A = 5

Grade B = 10

Grade C = 15

Grade D = 3

Grade F = 2

Sample space (S) = 35

Probability of getting grade A, P(A) =?

The probability that a student obtained a grade of A can be obtained as follow:

Probability of getting grade A, P(A) =

Event of A (nA) / Sample space, (nS)

P(A) = nA/nS

P(A) = 5/35

P(A) = 0.14

Thus, probability that a student obtained a grade of A is 0.14

I really need help <br> ;-;

Hi there! I can help you!

a. Okay. So we have to make a table for the amount of butterflies to total insects. Let's simplify the ratio. 36:100 simplifies to 9:25. We can use that ratio to make this table. Just multiply 25 by the amount it takes to get to 50 or 100, and multiply by the same amount at the top to find the amount of butterflies. If you do it correctly, your table should be as shown below in the image.

b. On that note, let's solve for the amount of butterflies in the conservatory. There are 450 total of them. Let's divide 450 by 100 to find the amount we will multiply by. 450/100 is 4.5. We will mutliply 36 by that amount to find the total amount of butterflies. 36 * 4.5 is 162. That's it. There are 162 butterflies in the conservatory.

A fulcrum moving a resistance of 200 g has a distance to the fulcrum of 20 cm, the effort mass of 50 g has a distance to the ful

Answer:

The ideal mechanical advantage (IMA) is 4.

Step-by-step explanation:

The ideal mechanical advantage is the ratio of length of longer lever L_e to that of shorter lever L_r

IMA \frac{L_e}{L_r}

Please refer to the image attached.

We could see that the the resistance load moves 10\ cm cm towards the fulcrum so the distance of resistance load from fulcrum = (20-10) =10\ cm

Now the as the effort force moves 40\ cm towards the fulcrum overall distance from the fulcrum to the effort force (load) =(80-40)=40\ cm

Plugging the values of the distances in IMA formula we can have.

IMA =\frac{(80-40)}{(20-10)} =\frac{40}{10}  =4.

So the IMA of the fulcrum (simple machine) = 4
