Answer:

Bob is paying more for the actual steak

Step-by-step explanation:

we know that

Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)

Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)

so

Bob's cut is 2/3 all meat

Find the unit rate of Bob's cut for all meat

\frac{13.98}{(2/3)} \frac{\$}{pounds} =20.97\frac{\$}{pounds}

therefore

\$20.97> \$19.98

Bob is paying more for the actual steak

The following are the ages (years) of 5 people in a room:
Nata [24]

Answer:

The age of the person who entered the room is 15

Step-by-step explanation:

Ages of 5 people in a room are:

17, 16, 15, 17, 22

A person enters room, the mean age of 6 people is 17.

We need to find the age of person who entered the room.

We know that: Mean=\frac{Sum\:of\:all\:data\:values}{Number\:of\:data\:Values}

Now, we have mean of 6 people that is 17

We know the age of 5 people while age of one person is unknown.

Let age of person which is unknown= x

So, we can write:

Sum of all data values = 17+16+ 15+ 17+ 22+x

where x is the age of person who enters the room.

Finding x

Mean=\frac{Sum\:of\:all\:data\:values}{Number\:of\:data\:Values}\\17=\frac{17+16+ 15+ 17+ 22+x}{6}\\17=\frac{87+x}{6}\\17*6=87+x\\102=87+x\\x=102-87\\x=15

So, we get the value of x: x=15

Therefore, the age of the person who entered the room is 15.

A sequence is defined by the explicit formula an=3n+4 Which recursive formula represents the same sequence of numbers?
fomenos

Answer:

Option (3)

Step-by-step explanation:

Explicit formula of the sequence is,

a_n=3^n+4

From this explicit formula,

First term of the sequence will be,

a_1=(3^1)+4

a_1=7

Second term of the sequence,

a_2=(3^2)+4

a_2 = 13

3rd term of the sequence,

a_{3}=(3^3)+4

   = 31

Sequence formed,

7, 13, 31 ..........

From the given options,

Recursive formula,

a_n=3a_{n-1}-8

a_2=3(a_1)-8

a_2=3(7)-8

a_2=21-8 = 13

a_3=3a_2-8

a_3=3a_2-8

a_3=3(13)-8

    = 39 - 8

    = 31

Sequence formed from this recursive formula will be,

7, 13, 31........

Therefore, Option (3) will be the answer.
