Answer:

I believe the answer is, 11.75.

-Hope this helps!

Step-by-step explanation:

To find the mean, you must add up all your data and divide it by how many people there are. So, all the numbers added together is, 82. Since there are seven kids, you would divide 82 by 7. Which equals, 11.75: (Simplified).

Answer:

See steps below

Step-by-step explanation:

Let F(x, y) and W be

F(x,y) = “x can fool y”

W the set of all the people in the world

a) Everybody can fool Fred.

$\forall x \in W,F(x, Fred)$

b) Evelyn can fool everybody.

$\forall y\in W, F(Evelyn, y)$

c) Everybody can fool somebody.

$\forall x \in W,\exists y :F(x,y)$

d) There is no one who can fool everybody.

$\nexists x \in W: \forall y ,F(x,y)$

e) No one can fool both Fred and Jennifer.

$\nexists x \in W: F(x,Fred)\wedge F(x,Jennifer)$

f) Nancy can fool exactly two people.

$\exists x,y \in W:\forall z\neq x,z\neq y, F(Nancy,x)\wedge F(Nancy,y)\wedge (\neg F(Nancy,z))$

7(x+3)=-2(x-5) Help pls?

olganol [36]

Answer:

x = -11/9

Step-by-step explanation:

7(x+3)=-2(x-5)

Distribute

7x+21 = -2x+10

Add 2x to each side

7x+21 +2x = -2x+10+2x

9x +21 = 10

Subtract 21 from each side

9x +21-21 = 10-21

9x = -11

Divide each side by 9

9x/9 = -11/9

x = -11/9

Write an explicit formula for an, the nth term of the sequence 19,24,29

o-na [289]

Answer:

explicit formula for an, the nth term of the sequence 19,24,29

$a_1=19 ; \ a_n=a_{n-1}+5$

Step-by-step explanation:

We need to Write an explicit formula for an, the nth term of the sequence 19,24,29

In the sequence the First term a₁= 19

Common Difference d= 5

The Formula used for explicit formula is: $a_1=First \ term ; \ a_n=a_{n-1}+d$

Where d is common difference and n is nth term of sequence.

So, explicit formula for an, the nth term of the sequence 19,24,29

$a_1=19 ; \ a_n=a_{n-1}+5$
