Answer:
Step-by-step explanation:
Grove City = 45,032
Franklin = 41,064
Franklin < Grove City
5 thousands > 1 thousand
The distributive property is being used because a is being distributed to b and c, which leaves you with ab + ac
Answer:
hypotenuse = 6.3
Step-by-step explanation:
here 6 and 2 are the legs of the triangle . we are asked to find hypotenuse (longest side)
using pythagoras theorem
a^2 + b^2 = c^2
6^2 + 2^2 = c^2
36 + 4 = c^2
40 = c^2
= c
6.32 = c
6.3 = c
With 10 integers available,
has PMF
We're interested in the statistics of the new random variable
. To do this, we need to know the PMF for
. This isn't too hard to find.
Since the PMF for
gives a value of
whenever
is an integer between 0 and 9, it follows that
must also be an integer for the PMF to give the identical value of
. This means
Now the mean (expectation) is
The variance would be
The standard deviation is the square root of the variance, so you have
There’s a 20% increase from last year to this year.
