It's 369.6
(840X44)/100 = 369.6
A+b=-10
ab=-75
a=-75/b
-75/b + b = -10
-75/b + b²/b = -10b/b
b²+10b-75=0
(b+15)(b-5)=0
b+15=0 or b-5=0,
b= -15, a=5
Sorry for the wait.....
Hope this helps and Happy Halloween!!!!
Question:
Discus the advantages and disadvantages of histograms versus stem-and-leaf plots
Answer:
C. Stem-and-leaf plots are easier to make and and can contain more information than histograms. However, they are not very useful for large data sets
Step-by-step explanation:
A stem and leaf plot is a graphical presentation of quantitative data similar to an histogram. However, a stem and leaf plot retains and present the values of the original in the data set such that individual data values can be seen and can then be used to make analysis
The stem and leaf plot consists of a stem and a leaf arranged in the order of place value, such that the numbers having a common highest place value are arranged on a row in a stem and leaf plot and therefore a stem and leaf plot is easier to make or construct than an histogram
However, it is very rare to find stem and leaf plots having more than 50 datasets or observations.
