Answer D The binomial must start at 0, but can increase to an infinite upper limit. Hope that helps.
I think that you typed wrongly. That has to be f(x)= -2x+8
If f(x)= -2x+8, we can solve that problem.
We replace x= -1.8 in that expression, that means: f(-1.8)= -2x(-1.8)+8= 3.6+8=11.6
But if the formula of f(x)=-2+8, that means f(x) has a stable value and that value is -2+8=6.
So for all x we always have f(x)=f(-1.8)=6
Answer:
He needs to buy 120 packages of dod food.
Step-by-step explanation:
b - bird food
h - hamster food
d - dog food
c - cat food
b + h + d + c = 600
b = h (bird food is the <em>same</em> as hamster food)
b = 4 d (bird food is <em>4 times</em> dod food)
c = d/2 (cat food is <em>half</em> dog food)
Total of packages ordered.
b + b + d + c = 600
4d + 4d + d + d/2 = 600
4 d + 4 d + d + d = 600. 2
10 d = 1.200
d= 120 .........the amount of dog food packages.
Answer:
18 million kilometers in one min. and 0.3 million kilometers in one second
Step-by-step explanation:
so the one min. is easy because all you have to do is take 180 and divide it by 10 and you get 18 million kilometers in one min. and then you would take 18 and divide it by 60 and you would get 0.3 million kilometers in one second
Answer:
0.0266, 0.9997,0.7856
Step-by-step explanation:
Given that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 points. Also suppose that IQs of students from university B can be described by a normal model with mean 120 and standard deviation 11. Let x be the score by A students and Y the score of B.
A)
B) Since X and Y are independent we have
X-Y is Normal with mean = 140-120 =20 and 
C) For a group of 3, average has std deviation =
