Answer:
if she cannot spend more than $40, she will spend .3 on each cupcake
Step-by-step explanation:
when you divide 12 by 40, you get .3 and to check if it is true, you can multiply .3 x 40 and you will get 12 hope you get it right, and have a good day :)
X + 19 >= 8.2
x >= 8.2 -19
>= -10.8
The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
Let X be the number of lightning strikes in a year at the top of particular mountain.
X follows Poisson distribution with mean μ = 3.8
We have to find here the probability that in randomly selected year the number of lightning strikes is 0
The Poisson probability is given by,
P(X=k) = 
Here we have X=0, mean =3.8
Hence probability that X=0 is given by
P(X=0) = 
P(X=0) = 
P(X=0) = 0.0224
The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
C! Like terms refer to the variables that are the same, rather than the coefficients (the numbers).
