The answer is 42 because there are 10 adults and
M=4(10)+2
M=40+2
M=42
Answer:
Histogram
Step-by-step explanation:
There are two types of data i.e. qualitative/categorical and quantitative/numerical data
Quantitative has further two more types i.e. discrete data and continuous data
To represent these types of data on a graph we commonly use three different types of graphs i.e. bar graph, histogram and pie chart
Bar graph is usually used to represent the discrete type of data
- It can either be quantitative or qualitative.
Histogram is used to represent the continuous type of data
- It can only be used for quantitative type of data
Pie chart can be either qualitative or quantitative, but it is expressed as the percent of the whole
As we know better that age is a continuous type of data as we are growing all the time
That is why to describe the variable age, I would like to use Histogram.

Explanation: A= b x h = 4 x 5 = 20
Answer:
a Dryer @ 4,000 watts. Cost = 172 cents
a Heater @ 1,500 watts. Cost = 64.5 cents
a Radio @ 40 watts. Cost = 1.72 cents.
Step-by-step explanation:
Given that cost of 1 kilowatt hour = 4.3 cents.
Then cost of 1 kilowatt for 10 hours = 4.3*10 = 43 cents.
4000 watts = 4000/1000 kilowatt = 4 kilowatts
Then cost for running a Dryer for 10 hours = 4*43 = 172 cents.
-----------
1500 watts = 1500/1000 kilowatt = 1.5 kilowatts
Then cost for running a Heater for 10 hours = 1.5*43 = 64.5 cents.
-----------
40 watts = 40/1000 kilowatt = 0.04 kilowatts
Then cost for running a Radio for 10 hours = 0.04*43 = 1.72 cents.
