Answer:

The third one is correct, the others bend the truth as they can touch but not overlap. As the third one states 'They are organized in equal intervals.'  this means they share an equal growth opportunity within their own column, their own height and nominated place within the histogram. The bars are of equal width and correspond to the equal class intervals. But on rare occasions like size classes they can be shown as a wider variant within their groups. Example would be showing a wider column say on classes at a school as the width and data being achieved forces a true event of variant sizes in education upon the base of the graph, this rarely applies to staff graphs as planning for schools is a wider data share than say offices using these types of graphs. Work development would use just data percentages along with the frequencies is one example so group size are stated in the reports to support more specific data in the graphs instead.

Step-by-step explanation:

To display numerical data that has been organized into equal intervals. The bars should touch the adjacent bars but not overlap. These intervals allow you to see the frequency distribution of the data, or how many pieces of data are in each interval.

Farhan orders one plate of seafood fried rice at a restaurant which offers at 25% discount. the Marked price of the seafood frie
ANTONII [103]

Answer:

The total amount of money he has to pay for the dish is $8.3861.

Step-by-step explanation:

Here, the marked price of the seafood fried rice  = $9.50

Now, discount on the marked price  = 25%

Calculating 25% of $9.50 = \frac{25}{100}  \times 9.50 = 2.375

So, the discount offered = $2.375

Now, the Selling Price of dish = Marked Price - Discount

                                                    =  $9.50 - $2.375   = $7.125

Now, here the service charge applied here  = 10%

Calculating 10% of $7.125 = \frac{10}{100}  \times 7.125 = 0.7125

So, the service charge applied  = $0.7125

So, the new Selling Price of dish = Selling Price + Service Charge

                                                    =  $7.125 + $0.7125   = $7.8375

Again, here the GST applied here  = 7%

Calculating 7% of $7.8375 = \frac{7}{100}  \times 7.8375 = 0.5486

So, the GST applied  = $0.5486

So, the new Selling Price of dish = Selling Price + GST

                                                    =  $7.8375 + $0.5486   = $8.3861

Hence, the total amount of money he has to pay for the dish is $8.3861.

The school is having a bake sale and the math club is bringing cupcakes. They have 180 total cupcakes, both chocolate and strawb
jeka57 [31]
Let s be the number of strawberry cupcakes, and c the number of chocolate cupcakes.
From our problem we know that the total number of cupcakes is  180, so c+s=180. We also know that the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes, so c-18=2s, or solving for c: c=2s+18.
Know we have our system of equations:
\left \{ {{c+s=180} \atop {c=2s+18}} \right.
We can conclude that the correct answer is <span>B. c + s = 180 c = 2s + 18.

Lets solve our equations to find how many cupcakes of each they have:
from our second equation we know that </span>c=2s+18; lets replace that value in our first equation to find the number of strawberry cupcakes:
2s+18+2=180
3s=162
s= \frac{162}{3}
s=54
<span>Now that we know the number of strawberry cupcakes, lets replace that value in our second equation to find the number of chocolate cupcakes:
</span>c=2(54)+18
c=108+18
c=126
As a bonus, we can conclude that the <span>math club have 126 chocolate cupcakes and 54 strawberry cupcakes. </span>
