Answer: A   M (2,-3)  and N ( 4,1)

Step-by-step explanation:

(-2, 3)  after a 180 degrees rotation the coordinates will be in the fourth quadrant (2,-3)  and the y coordinate is always negative in the fourth quadrant.

(-4,1)  after a 180 degrees rotation  the coordinates will be in the first quadrant (4,1) and all the coordinates will be positive.

Approximately 12.6% of all (untreated) Jonathan apples had bitter pit in a study conducted by the botanists Ratkowsky and Martin
bagirrra123 [75]

Answer:

Step-by-step explanation:

Let n be a random variable that represents the first Jonathan apple chosen at random that has bitter pit.

a) P(X = n) = q(n-1)p, where q = 1 - p.

From the information given, probability if success, p = 12.6/100 = 0.126

b) for n = 3, the probability value from the geometric probability distribution calculator is

P(n = 3) = 0.096

For n = 5, the probability value from the geometric probability distribution calculator is

P(n = 5) = 0.074

For n = 12, the probability value from the geometric probability distribution calculator is

P(n = 12) = 0.8

c) For n ≥ 5, the probability value from the geometric probability distribution calculator is

P(n ≥ 5) = 0.58

d) the expected number of apples that must be examined to find the first one with bitter pit is the mean.

Mean = 1/p

Mean = 1/0.126 = 7.9

Approximately 8 apples

What is 9 - (-8) = 20 and how did you get that answer?
Colt1911 [192]

Answer: No solution

Step-by-step explanation:

9-(-8)=20             given

9+8=20                the two negatives cancel out, making the eight positive

17=20                   this statement is not correct, so the answer is no solution

no solution

I'm not sure if there was supposed to be a variable in there somewhere, but I did my best to explain. Hope this helps!

Find the area: someone help me
Anna35 [415]
The answer is 56m^2.
The formula for finding area of a triangle is A=b•h/2.
So the base is 16m and the height is 7m. 16m•7m=112m^2
Now divide 112m^2 by 2.
112m^2/2=56m^2
