Answer:
-21x^2+50x-24
Step-by-step explanation:
3x((5)(2)-7x+2)-2((5)(2)-7x+2)
30x-21x^2+6x-20+14x-4
50x-21x^2-24
-21x^2+50x-24
Answer:
-.1
Step-by-step explanation:
First we do
19-1.67 since left to right
this is 2.3
then we multiply -2.4 with the + sign to get -2.4
then we add 2.3 to -2.4 to get -.1
ANSWER:
7 / 80
8 3/4% expressed as a fraction is 7 / 80.
STEP-BY-STEP EXPLANATION:
Write 8 3/4% as a percentage with a decimal:
= 8.75%
Convert 8.75% to a fraction:
= 8.75% ÷ 100
= 8.75 / 100
Make the numerator a whole number by multiplying both the numerator and denominator by a 100:
= ( 8.75 × 100 ) / ( 100 × 100 )
= 875 / 10000
Divide the numerator and denominator in the fraction by their highest common factor ( HCF ):
HCF = 125
THEREFORE:
= ( 875 ÷ 125 ) / ( 10000 ÷ 125 )
= 7 / 80
A histogram is better for "discrete" data and a frequency polygon is better for "continuous" data.
<h3>What is histogram?</h3>
A histogram is a data representation that looks like a bar graph and buckets a wide range of categories into columns all along horizontal x-axis.
- The numeric count or percentage of happenings in the data for every column is represented by the vertical y-axis.
- Columns can be employed to visualize data distribution patterns.
- Technical analysts use the MACD histogram in trading to making data in momentum.
- The MACD histogram columns could provide buy and sell signals earlier than the MACD and signal lines.
<h3>What is
frequency polygon?</h3>
Frequency polygons are a graphs depiction of the distribution that aids in data comprehension by utilizing a specific shape.
- Frequency polygons are comparable to histograms but are more beneficial when comparing two or more different data sets.
- The graph primarily displays cumulative frequency distribution data as a line graph.
- Frequency Polygons are a type of graph that deciphers information or data and are broadly used in statistics.
- This graphic form of data representation aids in the depiction of the data's shape and trend in a systematic and organized manner.
