It equals 24 bc 40/1=40 40+3=43 43-21=22 22+7=29 and 29-5=24
Answer:
Step-by-step explanation:
When we collect a large data we may find a single entry repeated. In these cases we prepare frequency distribution with x = the item in one column and f = the no of times it repeats i.e. frequency in other column.
Similarly for class intervals also, we write as frequency to the right side of interval column which gives no of items which fall within the class.
This process ensures compact presenting of data.
Hence we have
a)The number of observations that fall in a class
answer: Frequency
b) The relative frequency of a class multiplied by 100
answer: Percentage. Because when we express probability as a percentage we get total 100
c) The ratio of the frequency of a class to the total number of observations
answer: Relative frequency
(Relative frequency also known as probability is frequency/total entries)
Answer:
0.5(_12m_) - 0.5(_22n_)
Step-by-step explanation:
To apply the distributive property multiply each the term outside to each term in the parenthesis.
0.5(12m - 22n) 0.5(12m - 22n =0.5(_12m_) - 0.5(_22n_)
Answer:
y = 15x + 20 or 15x - y + 20 = 0
x = 11
Step-by-step explanation:
Line is passing through the points (0, 20) & (2, 50)
Slope of line = (50 - 20)/(2 - 0) = 30/2 = 15
Equation of line
y - 20 = 15(x - 0)
y - 20 = 15x
y = 15x + 20 or 15x - y + 20 = 0
Plug y = 185 in above equation, we find:
185 = 15x + 20
185 - 20 = 15x
165 = 15x
x = 165/15
x = 11
Answer=B
The explanatory variable is another term for the independent variable. The independent variable is the 'thing' that YOU decide to change/manipulate in an experiment. The type of nail polish given was the independent variable for this experiment.
