Describe the diagram

Mathematics
2 answers:
Degger [83]2 years ago
6 0

Answer:

The diagram represents 3 sets assuming they refer to 3 activities A, B and C.

The shaded point on A shows those engage in activities A only.

The shaded point on B shows those engage in activities B only.

The shaded point on C shows those engage in activities C only.

Incidentally the numbers of people engage in activities A only and B only are the same number.

The colour grade for the following is the same with that engage in only activity B;

The intersection of A and B

The intersection of B and C

The intersection of A and C

Therefore it means the numerical value is the same with that of B only;

A n B= B n C = A n C = n( B only); n on the right represent intersection and on the left number.

A n B n C = no of people engaged in all 3 activities.

A n B n C = n( A only) = n( B only) ;

From the colour grade

Note: n on the right represent intersection and on the left

Answer:

The diagram reprents the 3 sets and the universal set . The shaded portion clearly can be seen as :

A \cap B \cap C + A - (A \cap B) - (A \cap C) + A \cap B \cap C + C - (C \cap B) - ( C \cap A) + (A \cap B \cap C)

Shaded region = 3(A \cap B \cap C) + A + C - (A \cap B) - 2(A \cap C) - (C \cap B)

I NEED HELP PLEASEEEEEEEEEEEEEEEEEEEEEEEEE
ser-zykov [4K]

Answer:

58 square feet

Step-by-step explanation:

The room is already broken down into two smaller rectangles.

The smaller of the two measures 4 ft by 2 ft. A=lw, so substitute 4 for l and 2 for w.

A(smaller rectangle) =(4)(2), or (4*2).

A(smaller rectangle) =8

The larger measures 10 ft by 5 ft, so using the same method, multiply l times w.

A(larger rectangle) =(10)(5), or (10*5).

A(larger rectangle) =50

Add the two rectangles' areas together to find the total area of the room.

8 + 50 = 58

What weight of dry substance is in 150g of a 3% substance solution? What weight of an 8% solution can we have with the same weig
Leto [7]
<span>4.5 g 56.25 g Since the only type of measurement mentioned in this question is weight or mass, I'll assume that the percentage concentration is % m/m (mass/mass). For that type of concentration measurement, simply multiple the percentage by the total mass to get the mass of the desired substance. So 150 g * 3% = 150 g * 0.03 = 4.5g For the amount of 8% solution with the same amount of dry substance, there's 2 ways of calculating the mass of solution. First, use the ratio of percentages, multiplied by the mass of the original solution to get the desired amount of new solution: 3/8 * 150 g = 56.35 g Or calculate it from scratch, like 4.5/X = 8/100 450/X = 8 450 = 8X 56.25 = X In both cases, the result is that you desire 56.25 grams of 8% solution.</span>

shenika is inviting 7 friends to a party. if each friend will get 5 cookies and each box has 12 cookies. how many boxes does she
Naddik [55]

Answer:

Shenika invites 7 friends and each one gets 5 cookies.

= 7*5

= 35

Based on above answer, Shenika will need a total of 35 cookies for all.

-----------------------------------------------------------------------------------------------------------

Each box has 12 cookies.

Total cookies = 35

Let the number of boxes be x.

12*x = 35

x = 35/12

x = 2.9

This means she would need <em><u>3 boxes</u></em>.
