Answer:
y = 4x+3x^2
Step-by-step explanation:
For an equation to be linear, x must have a power of 1
y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)
Find how many weeks are in a year and times by 5.15
Answer:
-6
Step-by-step explanation:
From the information given:
Random wins 2000 800 400 0
Probabilities 1/10^4 4/10^4 10/10^4 9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92
Answer:
The length of the other leg is 8.94 m.
Step-by-step explanation:
Given that,
Hypotenuse of a right triangle is 12 m
The length of the one of the legs of a right triangle is 8 m
We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

H = hypotenuse = 12 m
b = base = 8 m

So, the length of the other leg is 8.94 m.
