Answer:
<h2>28 lollipops.</h2>Step-by-step explanation:
Let's say that is the total number of lollipops in the bag, which Matt won.
So, if Matt gave 21 lollipops to his friends, and he kept with 7 lollipops, that means there were 28 lollipops in the bag.
If we represent this as an equation, would be:
Where is friend's lollipops, and
is Matt's lollipops.
Replacing values we have:
Therefore, in the bag were 28 lollipops in total.

Answer:
2.35 calls
Step-by-step explanation:
The presented scenario can be modeled by a Poisson distribution with an average number of calls (μ) of 5.5 during the noon hour on Mondays.
Therefore, the standard deviation for the number of calls received, X, is given by:
The standard deviation of X is 2.35 calls.
The correct next step Amy could take is to factor (x^2 - 16) on the left side of the equation to yield (x + 4)(x – 4)(x + 2) = 0.
The equation is given as:
The possible next steps are:
1. Expand the equation as follows
2. Express x^2 -16 as a difference of two squares as follows
However, the correct step in this case is to factor x^2 - 16 as a difference of two squares to give
This is so, because the question says Amy is trying to solve for variable x.
This step will ensure that she gets the possible values of x, unlike expanding the whole equation .
Hence, the correct next step is
