Answer:
B. 108 calories
Step-by-step explanation:
The mean number of a data set is

Corn chips: 230 calories
Popcorn: 25 calories
Potato chips: 115 calories
Pretzels: 62 calories
Thus,
The sum of all calories 
The number of productrs = 4
The mean number of calories 
Answer:
B. y=2t-3
Step-by-step explanation:
First rewrite the parametric equation.
f(x)= y = at + b
Once arranged you get
2x - y =3
2x - 3 = y
f(x) = y = 2x - 3
Replace x with t, x = t
Answer:
Step-by-step explanation:
Solving for x means you have to factor. First factor out the GCF of 2 to get:
and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:
1, 18
2, 9
3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:
and
and
and
and
which finally simplifies to
No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
