Choose the method to solve the problem below: There are members on a board of directors. If they must form a subcommittee of mem
shepuryov [24]

Answer:

b. 56

Step-by-step explanation:

Please consider the complete question.

There are 8 members on a board of directors. If they must form a subcommittee of 3 members, how many different subcommittees are possible?

We will use combinations for solve our given problem.

^nC_r=\frac{n!}{r!(n-r)!}, where,

n = Number of total items,

r = Items being chosen at a time.

For our given scenario n=8 and r=3.

^8C_3=\frac{8!}{3!(8-3)!}

^8C_3=\frac{8!}{3!\cdot 5!}

^8C_3=\frac{8\cdot7\cdot6\cdot5!}{3\cdot2\cdot1\cdot 5!}

^8C_3=8\cdot7

^8C_3=56

Therefore, 56 different subcommittees are possible and option 'b' is the correct choice.

Prove the following statement. Assume that all sets are subsets of a universal set U.
nadezda [96]

Answer:

O U ⊆ A ∪ B                     True

O U ⊆ A ∩ B                    False

O A ∪ B ⊆ U                     True  

O B ⊆ U                            True

O A ⊆ U                            True

O A ∩ B ⊆ U                     True      

Step-by-step explanation:

To prove the first part

\text{If} \,\,\,\,\,\, A^{c} \subseteq B   \,\,\,\,\,\text{then} \,\,\,\,\, A \cup B = U

Remember that any set is a subset of the universal set. Therefore it is true that

A \cup B \subseteq U

Now, given any  x \in U   it is true that

x \in B  \,\,\,\, \text{or} \,\,\,\, x \notin B

Now according to the information given initially

\text{If} \,\,\,\,\, x \notin B  \,\,\,\,\, \text{then} \,\,\,\,\, x \notin A^{c}

And then you know that    

\text{If} \,\,\,\,\, x \notin A^{c} \,\,\,\,\,\text{then} \,\,\,\,\,\,\, x \in A

Therefore    U \subseteq A \cup B  and using double inclusion

U = A \cup B.

Now using the information just exposed

O U ⊆ A ∪ B                     True

O U ⊆ A ∩ B                    False

O A ∪ B ⊆ U                     True  

O B ⊆ U                            True

O A ⊆ U                            True

O A ∩ B ⊆ U                     True

Plz this is due today help me explain the answer
Natali [406]

Answer:

177.3 feet

This is a classic find the vertex of a parabola question.

if this was a calculus class the solution would be to take the derivative and set it equal to zero... -32t+ 105 = 0

BUT i assume that you are not in a calculus class..

so we try plan "B" the  highest (or lowest) point of parabola is it's vertex

the vertex formula is [-b/2a,f(-b/2a)]

in your problem a = -16, b=105, c= 5

so the "X" (TIME) is located at -(105)/(2*-16) = 3.28

plug in 3.28 into -16(3.28)^2 + 105(3.28) + 5 = 177.27

and you will get
