THE SLOPE IS -2
if we have the coordinates of two points on a line, we can find the slope with this formula:
so the slope is
the answer is -2
good luck
Total cost=variable cost+fixed cost
variable cost=1.25 times x or 1.25x
fixed cost=3
y=1.25x+3
f(x)=1.25x+3 is da rule
Let x represents the number of dvds sold per day:
To complete the probability distribution table, you need to add all the probabilities given and deduct that to 1 so that you can get the probability of 5-9, applying what I have said:Probability of 5-9:= 1 - (0.1875+0.4375+0.1250) = 1 – 0.75= 0.2500
But the question is not asking for the probability of 5-9, but 5 or more. So deduct the .1875 to 1 since .1875 only represents 0-4.P(X>= 5) = 1 - 0.1875 = 0.8125
Given the figure of a square pyramid
The area pf the base =area of the square of side 14 in =
the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in
so, the area of the sides =
So, the surface area of the pyramid =
So, the answer will be A = 532 in^2
