If no (A) = 40%, no (B) = 30%, n (A∩B) = 20% then find n (<br> (A B)<br> using formula.

Vesnalui [34]

Answer:

solution:-We know that for any two finite sets A and B, n(A∪B)=n(A)+n(B)−n(A∩B).

Here, it is given that n(A)=20,n(B)=30 and n(A∪B)=40, therefore,

n(A∪B)=n(A)+n(B)−n(A∩B)

⇒40=20+30−n(A∩B)

⇒40=50−n(A∩B)

⇒n(A∩B)=50−40

⇒n(A∩B)=10

Hence, n(A∩B)=10

Step-by-step explanation:

hope it helps you friend ☺️

(3x+7)(x+7)=0<br>What are the two possible values?

lana [24]

For the given equation, either 3x + 7 = 0 or x + 7 = 0

Now,

3x + 7 = 0

3x = -7

x = -7/3

x + 7 = 0

x = -7

So, possible values of x is : -7 and -7/3

Pls help me on this math watch!!! this is non calculator

Andru [333]

The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = $\frac{1}{3}$ πr²h

Now,

According to the problem,

$\frac{1}{3}$ πr²h = 102

or, $\frac{1}{3}$ × $\frac{22}{7}$ ×(4.96)²h= 102

or, h = $\frac{102X7X3}{4.96^{2}X22 }$

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)
