112 diapers online is a better deal since 56/28=2 and 112/52=2.15
Using the combination formula, the probability that Rosa's mom chooses sausage and onion is given by:
B. .
The order in which the toppings are chosen is not important, hence the <em>combination formula </em>is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
2 toppings are chosen from a set of 8, hence the number of options is given by:
.
Sausage and onion correspond to one topping, hence the probability is given by:
B. .

Answer:
8 units
Step-by-step explanation:
The last one
x + y = 25 is the number of pieces of fruit they will buy, where x is apples and y is oranges.
0.50x + 0.25y = 10 applies the cost, in cents, to each piece of fruit. The 10 is 10.00, keeping everything to the same number of decimal places.
The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
<h3>What is the parabola?</h3>
It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80
The vertex of the parabola will be at (–4, –80).
