When change in one variable is accompanied by the change of another variable in the same direction, they are directly proportional to each other, and it is usually represented by the general equation, y = kx where k is a constant.
X is 30 because
x-4x=-90
-3x=-90
x=30
Answer:
B. CT+TA=RM+MA
Step-by-step explanation:
I'm not quite sure what you mean.
the factors can't be 1.
the factors have to be odd.
they have to be the same.
offhand i would say 3*3*3*3 would be equal to 9*9 = 81.
the number 81 has 4 odd factors that are all the same.
can't be 1 because 1 doesn't counts as a factor.
a prime number has 2 factors.
1 and itself.
every number has a factor of 1 and itself.
The shape of distribution for a polygon of the average annual rainfall in Los Angeles over the past 110 years would be normal.
<h3>How to determine the
shape of
distribution?</h3>
In Statistics, the shape of distribution of a data set can be determined by examining the frequency distribution, which explicitly shows the number of score or numerical data associated with each member of a population.
Over the past 110 years, we can logically deduce that the shape of distribution for a polygon of the average annual rainfall in Los Angeles would be normal because very few number of years had extremely low rainfall, high rainfall and many years with average rainfalls.
