There are no tanks with less than 30 fish, so the first two groups ( 20-24) and (25-29) aren't used.

There are 3 tanks with 30-34 fish.

There are 3 tanks with 35-39 fish.

There are 3 tanks with 40-44 fish.

There are 1 tanks with 45-49 fish.

Now drag the bars for each group to the number of tanks.

Jerry played with 333 friends today, all at different times. He played with Tommy for 1\dfrac{7}{8}1 8 7 ​ 1, start fraction, 7,
Mars2501 [29]

Answer:

8 1/8 hours

Step-by-step explanation:

Jerry played with 3 friends today, all at different times.

Tommy = 1 7/8 hours

Nathan = 1 3/4 hours

Chris = 3 3/2 hours

How many hours did Jerry play with his 3 friends today?

Number of hours Jerry play with his 3 friends today = 1 7/8 + 1 3/4 + 3 3/2

= 15/8 + 7/4 + 9/2

= (15+14+36)/8

= 65/8

= 8 1/8 hours

If f and t are both even functions, is the product ft even? If f and t are both odd functions, is ft odd? What if f is even and
Natali5045456 [20]

Answer:

(a) If f and t are both even functions, product ft is even.

(b) If f and t are both odd functions, product ft is even.

(c) If f is even and t is odd, product ft is odd.

Step-by-step explanation:

Even function: A function g(x) is called an even function if

g(-x)=g(x)

Odd function: A function g(x) is called an odd function if

g(-x)=-g(x)

(a)

Let f and t are both even functions, then

f(-x)=f(x)

t(-x)=t(x)

The product of both functions is

ft(x)=f(x)t(x)

ft(-x)=f(-x)t(-x)

ft(-x)=f(x)t(x)

ft(-x)=ft(x)

The function ft is even function.

(b)

Let f and t are both odd functions, then

f(-x)=-f(x)

t(-x)=-t(x)

The product of both functions is

ft(x)=f(x)t(x)

ft(-x)=f(-x)t(-x)

ft(-x)=[-f(x)][-t(x)]

ft(-x)=ft(x)

The function ft is even function.

(c)

Let f is even and t odd function, then

f(-x)=f(x)

t(-x)=-t(x)

The product of both functions is

ft(x)=f(x)t(x)

ft(-x)=f(-x)t(-x)

ft(-x)=[f(x)][-t(x)]

ft(-x)=-ft(x)

The function ft is odd function.

If a fraction is a negative should the negative sign be in the numerator denominator both or it doesn't matter
Angelina_Jolie [31]
Here's the rule for working with these things:

There are 3 signs associated with a fraction:
=> the sign of the numerator
=> the sign of the denominator
=> the sign of the whole fraction; (if the fraction were in
     parentheses, this sign would be written outside).

-- You can change any 2 of them without changing the value of the fraction.

-- Changing any 1 of them changes the effective sign.
___________________________________

Now, you said the fraction is negative.
So, let's start with the positive fraction, and see the different ways
that we could make it a negative fraction:

=> mark only the numerator negative
=> mark only the denominator negative
=> put parentheses around the fraction, and mark it negative outside

If you do any one of these things to a normal positive fraction,
it turns into a negative fraction.

Look at the choices you listed in the question:

-- in the numerator only ?  Yes.  That makes it a negative fraction.

-- in the denominator only ?  Yes. That makes it a negative fraction.

-- both ?  No.  That makes it the same as a positive fraction. 

-- put parentheses around the fraction, and a negative sign outside ?
   Yes.  This makes it a negative fraction.

-- it doesn't matter ?   No.  I hope you can see that it does matter.

Have I confused you ?
Is this more than you wanted to know ?
