The number of students P(n), on each floor of a school building depends on the floor number n. What does the statement P(6) > P(1) + P(3) mean?​

Answer:

.39

Step-by-step explanation:

just did the math

Correct Answer is 0.13

Probability:

The probability formula is the number of favourable outcomes to the total number of all the possible outcomes.

The probability of an Event = (Number of favourable outcomes) / (Total number of possible outcomes)

P(A) = n(E) / n(S)

Here, (Given)

n(E) = The participant prefers football and the event is foam finger = 39

n(S) = Total number of outcomes = 300

P(A) = probability the participant prefers football and the event foam finger.

P(A) = 39 / 300

P(A) = 0.13

Answer:

x =  40

Step-by-step explanation:

.80x + 30 = 1.20x + 14

-.80x        = -.80x        

          30 = .4x  + 14

         -14 =         -14

           16 = .4x

            16/.4  = .4/.4x

              40    =  x

Answer:

56°

Step-by-step explanation:

1. the rule is: m(DCE)+m(DEC)+m(CDE)=180;

2. m(DCE)=180-(7x-2)=182-7x;

m(DEC)=180-(4x+33)=147-4x;

m(CDE)=180-(9x-31)=211-9x;

3. after the substitution all the angles (item 2) into the rule (item 1):

182-7x+147-4x+211-9x=180;

20x=360;

x=18;

4. if x=18, then filally, m(DCE)=182-7*18=56°.

Step-by-step explanation:

Given info:-

A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.

What is the CP of an article whose MP is Rs. 280 ?

Explanation:-

Given that

The Marked Price of an article (M) = Rs. 280

Discount on it = 20%

Discount (D) = MD/100

⇛ Discount = (280×20)/100

⇛ Discount = 28×2

⇛ Discount =56

Selling Price = Marked Price - Discount

⇛ Selling Price = 280-56

⇛ Selling Price = Rs. 224

Selling Price of the article = 224

Profit on it = 12%

We know that

Cost Price = (100×SP)/(100+g)

⇛ CP = (100×224)/(100+12)

⇛ CP = 22400/112

⇛ CP = 200

Therefore, The CP = Rs. 200

The Cost Price of the article = Rs. 200.

Formula:-

M = Marked Price

SP = Selling Price

g = gain or profit

Answer:

x = -9

Step-by-step explanation:

We will bring all the xs to the left side:

2x - 5 - 3x = 4

We will move -5 to the right side

2x - 3x = 4 + 5

Combine like terms:

-1x = 9

solve for x:

x = 9/-1 = -9

Step-by-step explanation:

2x-3x=4+5

-x=9

Therefore x=-9

According to graph, the answers are:

(1) H(0) = 6

(2) H(x) = 0, there are 5 points:

(3) The domain is:

(4) The range is:

Answer:

y= -x + 6

Step-by-step explanation:

-x + y =1 ---> y = x+1

the line perpendicular to this line should have negative inverse slope

the slope is 1 so the negative inverse of 1 is -1

set up

y = -x +b

since it goes through (4,2)

then we have

2 = -4 +b

b=6

so the linear equation is y = -x+6

Answer:b) If there are 20 squares there will be 25 triangles.

c) There are 20 girls

Step-by-step explanation:

b) The ratio here is 4(squares):5(triangles), so if there are 20 squares you have to divide that by the original number of squares, 4. Once you get that, you multiply it by the number of triangles, 5. The work should look something like this:

20/4 = 5

5 x 5 = 25

c) For this one you have to add the total number of students within the ratio. Since there 5 girls and 2 boys, that is 7 people in total. Since you’re trying to reach a total of 28, you divide 28 by 7, which will give you 4. Now, you multiply 4 by the number of just girls, (5), which gives you a total of 20.

Answer:

it’s B

Step-by-step explanation:

Answer:

Information given

3 blue

2 red

4 green

1 yellow

Total= 10

For (1)  for the probability of a green OR blue blocks you jsut gotta add up green and blue. 4+3=7 And 10 blocks in total so 7/10 chance

For (b) you find the probability of a green which is 4/10 and then a blue which is 3/10. So assumingg you draw twice you have 4/10*3/10 which is 12/100 chance of getting that order.

Well of course b is most likely to happen because its the most Chances.

7/10 > 12/100
