Given each scenario, identify an appropriate type of chart or plot that you would use to determine the answer. (e.g. pie chart,

scatterplot, etc.)
a) We want to understand distribution the cholesterol level of 100 males aged 20-30
b) Is the correlation between daily outside temperature and amount of natural gas used for heating positive or negative?
c) We want to understand the Indiana yearly harvest (in tons) of soybeans between 1985 and 2015
d) We want to see if there is a relationship between the weight of a passenger vehicle and fuel efficiency (measured as miles per gallon). We want to understand the distribution of yearly household incomes in Tippecanoe County for 2012. A poll of 200 undergraduates was taken. The respondents were asked to list all the modes of transportation used going from their home to campus What is the percentage of Indiana vehicles that are small passenger cars, large passenger cars, trucks, SUVs, and other types?

Answer:

a) dot plot

b) scatter plot

c) bar graph

d) scatter plot

e) histogram

f) pie chart

g) pie chart

Step-by-step explanation:

a) Cholesterol level for 100 males is observed, there is no grouping of people based on different range of cholesterol level, so the best chart for this dataset of 100 males will be a dot plot that shows all the 100 men’s cholesterol level on the chart and helping in depicting the trend as well.

b) For correlation of two factors the best graph is the scatter plot. If the direction of scatters is from lower left to upper right, then the relation is positive. But if the direction of the scatter points is from upper left to lower right then the relation is negative. Thus the best graph for it is scatter plot

c) A bar graph helps to plot the years on the x axis and the harvest on the y axis. A bar for each year is plotted and the length of the bar helps identify the value of yearly harvest.

d) For correlation of two factors the best graph is scatter plot. If the direction of scatters is from lower left to upper right, then the relation is positive. But if the direction of the scatter points is from upper left to lower right then the relation is negative.

Note: After question d) I have divided the questions into e), f) and g) as can be understood.

e) We want to understand the distribution of yearly household incomes in Tippecanoe County for 2012.

In order to understand the distribution of the household income a histogram can be used for the same. Continuous intervals of income can be formed. The bars of each range can be drawn and the distribution can be observed. If each range has same proportion of people the distribution is uniform, is it is lower at the extreme values and higher at the middle values then the distribution is normal and so on, such interpretations can be drawn from such a graph.

f) A poll of 200 undergraduates was taken. The respondents were asked to list all the modes of transportation used going from their home to campus.

Each mode of transportation can form one segment of pie chart. Thus pie chart helps in this kind of categorical data. Each segment size in the pie circle corresponds to the proportion of people in that segment.

g) What is the percentage of Indiana vehicles that are small passenger cars, large passenger cars, trucks, SUVs, and other types?

A pie chart can show the percent of each type of categories of cars. Each segment size in the pie circle corresponds to the proportion of people in that segment

Hope this helps!

Use the following information to complete parts I, II, and III. 1 hour=3600 seconds
lutik1710 [3]

Answer:

I) 8.760 * 10 ³ hours

II) 8.76582 * 10 ³ hours

Step-by-step explanation:

1) No. of hours in one year:

24 hours* 365 days= 8760 hours

Scientific Notation= 8.760 * 10 ³ hours

2) 1 year = 31556952 seconds

1 hour=3600

1 year = 31556952 seconds/3600  = 8765. 82 hours

Scientific Notation= 8.76582 * 10 ³ hours

3) The exact numbers of hours using 365 days is 8760 which is written as 8.760* 10 ³ in scientific notation. But using the given data we get =8.76582 * 10 ³ hours

Comparing these answers the first one  has only 3 significant figures

But the second answer has six significant figures if we round these we get 8.8  * 10 ³ hours which has two significant numbers

Aslo rounding the first gives 8.8 * 10 ³ hours which has two significant numbers  and is the same as the other answer rounded

olga55 [171]

Answer:

P(\text{Pizza}\ |\ \text{Female})=0.225

Step-by-step explanation:

The two-way frequency table is attached below.

We have to calculate the probability of, a person chosen at random prefers pizza given that they are female, i.e P(\text{Pizza}\ |\ \text{female})

This is a conditional probability.

We know that,

P(A\ |\ B)=\dfrac{P(A\ \cap\ B)}{P(B)}

So,

P(\text{Pizza}\ |\ \text{Female})=\dfrac{P(\text{Pizza}\ \cap\ \text{Female)}}{P({\text{Female}})}

From the table,

P(\text{Pizza}\ \cap\ \text{Female)}=\dfrac{119}{1000}

P({\text{Female}})=\dfrac{530}{1000}

Putting the values,

P(\text{Pizza}\ |\ \text{Female})=\dfrac{P(\text{Pizza}\ \cap\ \text{Female)}}{P({\text{Female}})}=\dfrac{\frac{119}{1000}}{\frac{530}{1000}}=0.225

1/b+x=3b/2x^2 - 1/x<br>btw ^2 means square<br><br>​
AlekseyPX

Answer:

x =  \frac{ - 3b}{4}  \: or \: b

Step-by-step explanation:

\frac{1}{b + x}  =  \frac{3b}{2 {x}^{2} }  -  \frac{1}{x}

=  >  \frac{1}{b + x}  =  \frac{3b - 2x}{2 {x}^{2} }

=  > 2 {x}^{2}  = (b + x)(3b - 2x)

=  > 2 {x}^{2}  = 3 {b}^{2}  - 2bx + 3bx - 2 {x}^{2}

=  > 2 {b}^{2}  = 3 {b}^{2}  + bx - 2 {x}^{2}

=  > 3 {b}^{2}  + bx - 4 {x}^{2}  = 0

=  > 3 {b}^{2}  + 4bx - 3bx - 4 {x}^{2}  = 0

=  > b(3b + 4x) - x(3b + 4x) = 0

=  > (3b + 4x)(b - x) = 0

Hence,

x =  \frac{ - 3b}{4}  \: or \: b
