$\dfrac{q+5}{-3}\cdot\dfrac{-3q}{q+2}=\dfrac{(q+5)(-3q)}{(-3)(q+2)}\qquad\text{use distributive property}\\\\=\dfrac{(q)(-3q)+(5)(-3q)}{(-3)(q)+(-3)(2)}=\dfrac{-3q^2-15q}{-3q-6};\ q\neq(-2)$

Answer:

a. Genre with highest mean is drama. Mean is 72.10

B. 10.46 is difference between means of comedy and horror

C. Horror has the lowest minimum value at 25.00

Action and comedy both have the highest maximum value at 93.00

Step-by-step explanation:

First create a table with the data provided like I did in the attachment. It would give a clearer picture of what your answers should be.

1. Which genre has the highest mean score?

From the table, we have the means as:

Action = 58.63

Comedy = 59.11

Drama = 72.10

Horror = 48.65

The genre with the highest score is drama at 72.10

2. Difference in mean score between comedy and horror

Mean of comedy = lc = 59.11

Mean of horror = ly = 48.65

Difference = lc-ly

= 59.11 - 48.65

= 10.46

3. The genre with lowest score is the genre with the lowest minimum value. This genre is horror and the lowest minimum is 25.00

The genre with highest minimum value is that whose maximum value is the highest out of all the genres. Both action and comedy have the highest maximum value at 93.00

2l+l=39
3l=39
divide by 3
l=13

subsitue
t=2l
t=2(13)
t=26

tim has 26 and luke has 13

Sharif likes exersicing.He goes hill-climbing every 12 days anf goes swimming every 8 days.If je goes hill-climbing and swimming

topjm [15]

This is a lowest common multiple question.
to find the lowest common multiple, you need to find the prime factors of the two numbers:
$8 = 2 , 2 , 2$
$12 = 2 , 2 , 3$
Take out duplicates:
$2,2,2,3$
and multiply them together:
$2*2*2*3 = 24$
and that is your answer.
Easy peasy.

A fish tank has the shape of a rectangular prism. It has a length of 2 1/4 m, width of 7/8 m, and a height of 1 1/2 m. What is t

Andru [333]

Data:
l (lenght) = $2 \frac{1}{4} m$ = $\frac{9}{4}m$
w (widht) = $\frac{7}{8}m$
h (height) = $1 \frac{1}{2} m$ = $\frac{3}{2} m$
V (volume) = ?

Formula:
$V = l*w*h$

Solving:
$V = l*w*h$
$V = \frac{9}{4} * \frac{7}{8} * \frac{3}{2}$
$V = \frac{189}{64}m^3$

<span>Transforming into a mixed fraction:
</span>
.....................189 |_64 → denominator
<span>numerator</span>←(61)....2.→Whole part

Stays like this: $2 \frac{61}{64}$

Therefore:
$V = \frac{189}{64}m^3\:\longrightarrow\:\boxed{\boxed{V=2 \frac{61}{64}m^3 }}\end{array}}\qquad\quad\checkmark$
