As gamers progress through a video game, they earn a higher rank. In an online gaming network, gamers can see what fraction of t

he way they
are to the next rank. The line plot displays the fraction of the way to the next rank for all the gamers in the network. What fraction of gamers
have bof the way to go to the next rank?

Question isn't well formatted, a picture if the question is attached below.

Answer:

1 / 4

Step-by-step explanation:

From the plot, each dot represent a gamer ; therefore, the total number of gamers will be counting all the dots ;

Total number of gamers = 24

Fraction of gamers that have 7 / 8 of the way to go ;

This means that they have 7/8 of the way left to proceed to next level ;

The fraction is : 1 - 7/8 = 1 /8

This means the number of of people whose progress are on 1/8 ; this is 6

Hence, fraction of gamers that have 7/8 of the way to go :

6 / 24 = 1 / 4

What is one solution to the system of equations graphed here?
Yakvenalex [24]

Answer:

(-2, 4)

Step-by-step explanation:

Hello!

There are two solutions for this system, which can be found by looking at the intersections of the two graphs.

The first intersection is at point (-2, 4), and the second one is at point (4, -3).

Since the second option is not a given option, it is the last option (-2, 4).

Can someone tell me why the answer is wrong!! I don't get that!! Plz help!!

Note that it said find "a" formula for P(x).  We can infer from this as there are multiple possibilities.
In fact, there are many possible P(x) that fits the bill.
You got the most important part correct, namely
(x+5)(x-5)^2.
In general, P(x)=A(x+5)(x-5)^2 will work, but we need to satisfy also y-intercept of P(0)=-75.
If we expand the expression, we get 
P(x)=A*x^3A-5A*x^2-25A*x+125A
=>
P(0)=125A.
So setting A=-3/5 => P(0)=-75 as required.
or 
P(x)=-3/5(x+5)(x-5)^2
will satisfy all requirements.
It would be nice exercise for you to confirm that it is indeed the polynomial required.

Grant Valley School has hired a fleet of buses and vans to transport 96 students to a picnic. Each bus can seat 31 people, and e
EleoNora [17]

Answer:

Number of buses = 2

Number of vans = 5

Step-by-step explanation:

Solution:

Number of buses = a

Number of vans = b

Number of people= 107

Now according to given statement each bus can seat 31 people and there are three teachers travelling in each bus.

Then the number of students in 'a' buses = (31-3)a = 28a students

Each van can seat 9 people and each van has one teacher. Then the number of students in 'b' vans= (9-1)b = 8b students.

The Grant Valley school has hired a fleet of buses and vans to transport 96 students to a picnic

Then the equation we get is:

28a+ 8b= 96

The buses and vans will take to accommodate 107 people including the teachers and 96 students.

Then the number of teachers will be:

Subtract the number of students from the number of people.

107-96 = 11

'a' number of buses will take 3a teachers and  'b' number of vans will take b teachers

So we got another equation:

3a+b=11

Now we have 2 equations:

28a+8b=96 ------- equation1

3a+b=11   -----------equation2

Solve the system of equation:

We will apply elimination method.

Multiply equation 2 by 4 and then subtract equation 2 from equation 1:

28a+8b=96

24a+8b=88            ------- (equation 2 after multiplication)

__________

4a        =8

Divide both the sides by 4

4a/4 = 8/4

a= 2

Now put the value of a in any of the above equation. We will put the value of a in equation 1.

28(2)+8b=96

56+8b=96

8b = 96-56

8b = 40

Divide both the sides by 8:

8b/8 = 40/8

b= 5

Number of buses = 2

Number of vans = 5....

Find (f•g)(x) when f(x)=sqrt x+3/x and g(x)=sqrt x+3/2x
elena-14-01-66 [18.8K]
For multiplying radical expressions, we are first to list down the given.
  f(x) = (x + 3/x)^(1/2),   and
  g(x) = (x + 3/2x)^(1/2) 

We take a look at first the values of the radicands, these are the numbers inside the radical signs. Since, both of the radicands are raised to exponent 1/2, it is easy to say that we just have to multiply them and raise the product to the exponent 1/2 as well. That is,
 
(f·g)(x)  = ((x + 3/x)(x + 3/2x))^(1/2)

Simplifying,
(f·g)(x) = ((x² + 3/2 + 3 + 9/2x²)^(1/2))

Further simplification will lead us to the final answer of,
<em>(f·g)(x) = (x² + 9/2 + 9/2x²)^(1/2)</em>
