Substitute the given points into the slope formula

step 2Equation of a line


Step 3

The final answerOption B
Complementary angles = two angles that add to 90° complement each other.
So, angle x = 3y+18
y= complementary angle
(3y + 18) + y = 90
4y+18 = 90
4y=72
y=18°
x= 3y+18
x= 3(18) +18
angle x = 72°
Answer:
17.08, 1.604
Step-by-step explanation:
given that an appliance dealer sells three different models of upright freezers
as per data given below:
x 14.5 16.9 19.1 Total
p 0.2 0.5 0.3 1
x*p 2.9 8.45 5.73 17.08
x^*p 42.05 142.805 109.443 294.298
Thus we find mean of X = 17.08
Var(x) = 
Std dev (x) = 
b) Price = 25x-8.5
E(price) = 
c) Var (price) =
