Step-by-step explanation:
180° = m<A + m<B + m<C
180° = 45° +60° + m<C
180° = 105° + m<C
m<C = 180° - 105 °
m<C = 75°
Answer:
Assume the random variable X has Poisson distribution.
The mean of X is given as
μ
=
7.
As mean of Poisson distribution is equal to...
Answer:
a, -b
Step-by-step explanation:
When x is a, the function becomes

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

As you see -b+b is 0, and once again, this would make the whole function 0.
The interquartile range is from Q1 to Q3 and to get this you have to subtract Q2 by Q3. The 10 units represent that only 10 units are fit in the given range.
Answer:
B. Unlikely
Step-by-step explanation:
Generally speaking, a probability of 0.11 to 0.40 is unlikely. 1/5 is 0.2, which falls in this range.
