2. the histogram shows the prices of dinners at a local fine-dining restaurant.
(a) how many total dinners are included in the histogram?
(b) what is the most popular price range of the dinners?

a). Total dinner are 10

b). 15 - 45 is the most popular price of dinner.

Step-by-step explanation:

Given: Histogram

To find: a). Total dinners

             b). The most popular price range of the dinners  

We are given:

Prices of Dinners on X axis with width of 15 units and

Frequency on Y axis with Scale of 1 unit = 0.5

First we convert Histogram in Data of Tabular form,

Table is attached

Now from table,

a). Total dinner = 3 + 3 + 2 + 2

                         = 6 + 4

                        = 10

b). Since, 15 - 30 and 30 -45 has equal no of frequencies

    So, 15 - 45 is the most popular price of dinner.

Therefore, a). Total dinner are 10

                  b). 15 - 45 is the most popular price of dinner.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
