Answer:
y=-4/6+2
Step-by-step explanation:
The rise is -4, and the run is 6. Rise over run means that the slope is -4/6. the Y intercept is 2. Therefore y=-4/6+2.
Given => ABCD is a rectangle.
Where AB(length) = 12.5 units
AD(breadth) = 2.5 units
Area of rectangle = length × breadth
= 12.5 × 2.5
= 31.25 unit²
Hope this helps!
We have given
hypotenuse=<span>6√2
let us suppose leg =a
using Pythagorean theorem
a^2+a^2=(</span><span>6√2)^2
</span>2a^2=36*2
diving by 2 on both sides
a^2=36
taking square root on both sides
√a^2 =<span>√36
a=6
therefore
</span><span>the leg of each isosceles right triangle is 6</span>
Answer:
Step-by-step explanation:
Given that 30% of all students who have to buy a text for a particular course want a new copy (the successes!), whereas the other 70% want a used copy.
Each purchaser is independent of the other and there are only two outcomes
X - no of persons who prefer new copies is Bin (15, 0.3)
a) E(x) = np =
Var(x) = npq = 
Std dev (x) = 1.775
b)
c) 
d) h(X) = revenue when x of 15 purchasers want new copies
E(h(x)) = 100(E(x) = 450
Here h(x) = 100x
Hence E(100x) = 100E(X)
