Bar graph display directly the varibales which are the rate and ratio of the numbers to visualize and display the results, these contrasting the different outcomes. On the contrary, histogram is used in grouped frequency parameters. Moreover, as little as the given five parameters or data set this will be ineffective and will result to a bar graph only and basically, the suited option is the aforementioned vertical graph to display the numbers. To expound on the definition of histogram it is used when the frequency is grouped. For example the data set of 1-5, 6-10, 11-15 and 16-20 this now can be used and applied to illustrate histogram because of the number and quantity of the given data.<span>

If a and b represent positive real numbers, what is the inequality when solved for V?
Nutka1998 [239]

Answer:

C. v < (3au - 60)/2b

Step-by-step explanation:

Given

au/2 - bv/3 > 10

Required

Solve for v

We start by rewriting the inequality

au/2 - bv/3 > 10 becomes

½(au) - ⅓(bv) > 10

Multiply both sides by 6

6 * ½(au) - 6 * ⅓(bv) > 6 * 10

3au - 2bv > 60

Make -2bv the subject of formula

-2bv > 60 - 3au

Multiply both sides by -½

[When multiplying or dividing an inequality by a negative number, the sign of the inequality will change]

-½ * -2bv < -½(60 - 3au)

bv < -½(60 - 3au)

bv < ½(3au - 60)

bv < (3au - 60)/2

Divide both sides by b

v < (3au - 60)/2b

Option C is correct

The sunshine ski shop makes a profit of $40 on each pair of skis sold. Shop expenses for one week are 2,480. What is the minimum
vivado [14]

Answer:

Number of units to sell= 112 units

Step-by-step explanation:

Giving the following information:

Unitary contribution margin= $40

Fixed costs= $2,480

Desired profit= $2,000

<u>To calculate the number of units to be sold, we need to use the following formula:</u>

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= (2,480 + 2,000) / 40

Break-even point in units= 112 units
