forsale [732]

Answer:

They must sell 106 more pizzas to earn $750.

Step-by-step explanation:

We are given that Mrs. Canale class is selling frozen pizzas to earn morning for a field trip. For every pizza sold, the class makes $5.35.

They have already earned $182.90, but they need $750. We have to find that how many more pizzas must they sell to be able to earn $750.

So, Firstly we will find that how much money did they have to earn more to be able to reach at $750.

Since, it is given that they have already earned $182.90.

So, Amount of more money they have to earn to reach at $750 = Final amount - Amount they already have

= $750 - $182.90 = $567.1

<em>That means they have to earn $567.1 more to be able to reach at $750 mark. </em>

Also, it is known that the price of every pizza sold = $5.35

So, Number of pizza that should be sold to earn an amount of $567.1 is given by;

<u>Number of pizzas</u> = $\frac{567.1}{5.35}$ = $\frac{5670}{535}$ = 106

Therefore, Mrs. Canale class must sell 106 more pizzas to be able to earn a total amount of $750.

Steve is managing a skate park and has been analyzing the attendance data. Steve has found that the number of visitors increases

SashulF [63]

Answer:

Suppose that the equations are:

The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.

N(T) = a0*r^(T)

Also, the number of people that leaves the park as the temperature increases are:

M(T) = a*T + b

So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:

N(T) - M(T) = total change in the park population as the temperature changes = C(T)

C(T) = a0*r^(T) - a*T - b

Determine if the following event is independent or dependent. Ursula went to the market and chose a blue marker from one box of

erastova [34]

Because is likely that the first outcome affected the second one, we can conclude that the events are dependent.

<h3>When two events are independent?</h3>

Two events are independent if the outcome of one can't affect the outcome of the other.

Here, first, she chooses a blue marker from one box and then a yellow one from another, these are the two events.

Now, these are independent or dependent?.

Well, the fact that she chooses a blue marker first, means that she probably would not want to choose another blue marker for the second one. So yes, the first outcome does affect the second outcome, meaning that the events are dependent.
