Answer:

B. the mean

Step-by-step explanation:

According to the Bar Chart shown, the number of DVDs sold at a local music store during one week are displayed.

Therefore, the measure(s) of central tendency that can be used to determine the average number of DVDs sold each day is the mean.

This is because the mean is the sum total of the number of DVDs sold, divided by the number, which gives the average.

Does this graph represent a function? Why or why not?

malfutka [58]

Answer:

Yes.

Step-by-step explanation:

It is a function because it passes the vertical line test. Each x-value has just one y-value. If the relation had any x-values that had several y-values, it would just be a relation. But this one is a function.

Hope this helps!

Answer:

a = 12

b = 2

c = 11

Step-by-step explanation:

$\frac{( {x}^{5}y {z}^{4} )^{3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{5 \times 3}y^{3} {z}^{4 \times 3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{15}y^{3} {z}^{12} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{15 - 3} {y}^{3 - 1} {z}^{12 - 1} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{12} {y}^{2} {z}^{11} = {x}^{a} {y}^{b} {z}^{c} \\ \\ equating \: like \: terms \: from \: both \: sides \\ \\ {x}^{12} = {x}^{a} \: \implies \: a = \boxed{ 12}\\ \\ {y}^{2} = {y}^{b} \: \implies \: b = \boxed{ 2} \\ \\ {z}^{11} = {z}^{c} \: \implies \: c = \boxed{ 11}$

a student spends the same amount each week for bus fare. In 5 weeks, he spends $115. Write an equation for his relationship. Let

dem82 [27]

Answer:

f(x) = ($23/week)(x)

Step-by-step explanation:

Hello!

Let's determine the unit rate. I'd suggest finding the cost per week, rather than the weeks covered by a certain amount of money.

Then:

$115

-------- = $23 per week

Then the amount spent as a function of the # of weeks would be:

f(x) = ($23/week)(x)

If f (1) = 7 and f (n) = 4 f (n - 1) then find the value of f (5)

Elina [12.6K]

Answer:

1792

Step-by-step explanation:

given,

f (n) = 4 f (n - 1)

here,

f(2) = 4 f ( 2-1)

= 4 f ( 1 )

= 4. 7

= 28

then,

f(3) = 4 f ( 3-1)

= 4 f ( 2)

= 4. 28

= 112

again,

f (4) = 4 f ( 4-1)

= 4 f ( 3)

= 4.112

=448

at last,

f ( 5) = 4 f ( 5-1)

= 4 f ( 4)

= 4. 448

= 1792
