X 0 y was 30
at x 12 y is about 55
12-0 = 12
55-30 = 25
25/12 = 2.08 inches per year average
so answer should be D
You need to use a common denominator. The least common denominator of 11 and 22 is 22.
3/22 + -1/11 = 3/22 + -2/22 = 3/22 - 2/22 = 1/22
Answer:
(4, 7)
Step-by-step explanation:
The point of interest is ...
P = (2Z +1Y)/(2+1) = ((2·3+6)/3, (2·9+3)/3)
P = (4, 7)

The point that divides the segment into the ratio a:b is the weighted average of the endpoints, with the weights being "b" and "a". The weight of the first end point corresponds to the length of the far end of the segment.
Answer:
The coordinates of his position is (-6,-8).
Step-by-step explanation:
Consider the provided information.
Let's assume for a moment that we are standing at the origin and the positive y-axis points due North while the positive x-axis points due East.
North represents the positive y axis, then south will represents the negative y axis.
It is given that the east represents the positive x axis then west represents the negative x axis.
Sasquatch-o-meter tells us that Sasquatch is 6 miles West and 8 miles South of our current position.
6 miles west represents a x=-6 and also 8 miles south represents y=-8
Thus, the coordinates of his position is (-6,-8).
Answer:
P[X=3,Y=3] = 0.0416
Step-by-step explanation:
Solution:
- X is the RV denoting the no. of customers in line.
- Y is the sum of Customers C.
- Where no. of Customers C's to be summed is equal to the X value.
- Since both events are independent we have:
P[X=3,Y=3] = P[X=3]*P[Y=3/X=3]
P[X=3].P[Y=3/X=3] = P[X=3]*P[C1+C2+C3=3/X=3]
P[X=3]*P[C1+C2+C3=3/X=3] = P[X=3]*P[C1=1,C2=1,C3=1]
P[X=3]*P[C1=1,C2=1,C3=1] = P[X=3]*(P[C=1]^3)
- Thus, we have:
P[X=3,Y=3] = P[X=3]*(P[C=1]^3) = 0.25*(0.55)^3
P[X=3,Y=3] = 0.0416
