The answers to the questions are as follows:

  • The value of the empty box in the diagram is 10
  • The probability that the number is in AnB = 1/5

<h3>How to solve the Venn diagram</h3>

We have E = {1, 3,5, 7, 9, 11, 13, 15, 17, 19}

A= { 3, 7, 9, 11, 15}

B = {5, 7, 11, 13}

We have A n B = numbers that are contained in both of the sets

= 7, 11

a.) We have to count the total number in the dataset. That is the total number of odd numbers that are less than 20.

Hence total numbers in the set = 10

b. The probability that the number is in set AnB

= 7, 11

= 2/10

= 1/5

We can conclude that the probability that the number is in A intersect B = 1/5

A negative number is 12 less than it’s square.find the number
butalik [34]

Answer:

A negative number that is 12 less than its square is -3.

Step-by-step explanation:

This is because (-3)² = 9 and 9 - 12 = -3.

You can get this answer by testing different number until one works in the given situation. This is done by testing numbers by squaring them and then subtracting 12 to see if it equals the original number.

Use 1/2ab sin C formula pls
Harman [31]

Step-by-step explanation:

area =  \frac{1}{2} a.b \sin(C)  \\ from \:cosine \: rule \\  {c}^{2}  =  {a}^{2}  +  {b}^{2}  - 2a.b \cos(C)  \\ 36 = 144 + 81 - (2 \times 12 \times 9) \cos(C)  \\ 189 = 216 \cos(C)  \\  \cos(C)  = 0.875 \\ C =  \cos {}^{ - 1} (0.875) \\ C = 28.96 \degree \\ area =  \frac{1}{2}  \times 144 \times 9 \times  \sin(28.96 \degree)  \\ area = 313.8 \: sq \: units

A cake is made out of 2 identical trapezoids. Each trapezoid has a height of 11 inches and base of 9 inches and 14 inches . What
a_sh-v [17]

Answer:

Area is 126.5 inches^2

Step-by-step explanation:

Mathematically, to calculate the area of the trapezoid, we use the following mathematical formula;

A = 1/2(a + b) h

here, a and b represents the two parallel sides which is 9 and 14 inches here and h which is the height is 11

Plugging these values into the equation, we have

A = 1/2(9 + 14)11

= 1/2(23)11 = (23*11)/2 = 126.5 inches^2

In the distance, an airplane is taking off. As it ascends during take-off, it makes a slanted line that cuts through the rainbow
irakobra [83]

Answer:

The equation of the parabola is given to be : y = -x² + 36

So, the airplane will cut the rainbow if the graph of the equation of airplane intersects the graph of rainbow.

Now, to find the equation of airplane :

The points through which airplane passes are : (1,0) and (0,2)

⇒ Equation : 2x + y = 2

This equation will  intersect the parabola at exactly two points.

And the points are the solution of these two equation :

(-4.916,11.832) and (6.916,-11.832)

The required table is :

x        -4.916       11.832

y         6.916      -11.832
