Y^2-5y+1- a= 4y^2-y+7
a=y^2- 4y^2-5y+y+1-7
a= -3 y^2 - 4y - 6 this is the polynomial
The probability of a screen being damaged is:
P(d)=3/13=0.23
Thus to get the probability that the first 10 sold were undamaged we use the binomial distribution formula:
P(x)=n!/((n-x)!x!)p^x(1-p)^(n-x)
from the question:
n=13, x=10, p=0.23
hence
P(x)=13!/((13-10)!10!)*0.23^(13-10)*(1-0.23)^(10)
simplifying the above we get:
P(x)=0.255
The correct answer is the larger one is 30 and the smaller one is 12 because 42-18 gives you 24 so you do 24/2 you get 12 so you add 18 to one of the 12s and you get the answer as 12 and 30
Answer:
33 feet
Step-by-step explanation:
We can draw a triangle in this situation.
<u>Note:</u>
The height of the tree is the side "opposite" of the 35 angle. The squirrel's distance of 47 feet from the base of the tree is the side "adjacent" to the angle.
Which trig ratio relates "opposite" and "adjacent"?
It is Tan
Thus we can write and solve (let height of tree be h):
To the nearest foot, the height of tree is about 33 feet
